					<description><![CDATA[Here’s a guide on how to regain administrator privileges after the person in charge of your WordPress site—which you had outsourced to a production company—has resigned or gone out of business. Unable to Update Plugins, etc., Due to Lack of WordPress Administrator Permissions When a WordPress development company delivers a site, they may provide the site operator with a user account that only allows editing and adding posts and static pages—to prevent accidental updates or bugs. (This account lacks the permissions to update or add/modify plugins.) However, it’s common for the development company to go out of business or for the person in charge to leave, making it difficult to log in with stronger permissions (permissions to update WordPress itself, plugins, or themes). This can lead to vulnerabilities being left unaddressed, resulting in malware infections, the inability to use new features, or the inability to update PHP(because the plugins are outdated and do not support the new PHP version). Enabling Login with Administrator Privileges In this case, the quickest solution is to upload database access software to the server, manually change the administrator password, and then log in as an administrator. Upload the PHP program above to the server using an FTP client, access it, and enter the database connection settings stored in WordPress’s `wp-config.php` file to log in to the database. Open the table with the prefix _users (usually wp_users). Create a password for the administrator user (typically created by the development company), hash it using MD5, and save it. This will allow you to log in as this user. *Generally, the administrator user has an ID of 1. You can verify whether this user actually has administrator privileges by checking the wp_usermeta table for the following entry under user_id 1 (the user’s ID): wp_capabilities a:1:{s:13:&#8221;administrator&#8221;;b:1;} If you are able to log in to a site that hasn’t been updated for a long time, we also recommend running a malware scan and vulnerability assessment. [Free] WordPress: Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal] What if you still can’t log in with administrator privileges? If you are unable to log in as an administrator, or if you can log in but cannot update plugins, it may be because code restricting functionality has been added to the theme’s `functions.php` file, or because a permission-restriction plugin is limiting your access.]]></description>

					<description><![CDATA[The site looks normal, but search results are flooded with product pages or appear in Chinese—here’s an explanation of how to detect and completely remove SEO spam. What Is SEO Spam? If the Google search results for your company’s WordPress site are filled with a large number of unfamiliar product pages or pages in Chinese, and clicking on those links leads to your company’s domain (even if they eventually redirect to another site, this still counts as SEO spam), it is highly likely that your site has been tampered with through a hacking attack known as SEO spam. The specific methods hackers use for SEO spam are as follows: ・Hackers exploit vulnerabilities in your site to gain permissions that allow them to overwrite databases, content, sitemaps, and other elements on your server. ・Hackers place unauthorized content on the site, alter sitemaps, or embed unauthorized links and forced redirection code into pages, causing search engines to mistake these for legitimate pages and index them ・Search results become contaminated with fraudulent pages. ・If users accidentally purchase products, their credit card information may be leaked, or they may download viruses, potentially leading to secondary damage. How do you remove SEO spam? To remove SEO spam, you must inspect and remove the compromised parts of your WordPress site. The following files are commonly compromised: index.php Theme’s index.php wp-config.php Theme’s functions.php Theme’s header.php However, other files may also be compromised, and in many cases, hackers may have installed a “backdoor”—a type of file that allows them to freely alter server content—deep within the system. Since manually opening and inspecting each file one by one is not practical, we recommend using a dedicated plugin to comprehensively scan and remove malware from all files on your site. [Free] WordPress: Malware Scan &#038; Security Plugin [Malware &#038; Virus Detection and Removal] After removal, how long does it take for the contaminated search results to disappear and return to normal? If the tampering has been completely removed, the contamination in most search results is often cleared within one week to one month. However, this depends on how frequently Google crawls the site, so it is difficult to predict the exact timeframe. Based on our experience, registering a new, cleaned-up sitemap via Search Console does not seem to significantly affect this process. However, if only a few malicious pages appear in search results, setting those pages to be excluded from search rankings via Search Console may cause them to disappear somewhat faster. To temporarily remove pages from search results via Search Console (URL Removal Tool) ・Log in to Search Console (search.google.com/search-console) ・Select “Indexing” → “Removal” from the left menu ・Click “New Request” ・Enter the target URL in the “Temporary Removal” tab ・Click “Next” → “Submit” to complete the process The page will be hidden from search results for approximately 6 months. If you want to permanently exclude it, the page itself must no longer exist. After removing malware, you must patch the vulnerabilities Once you’ve removed the hacker’s tampering, you must first patch the vulnerability that allowed the hacker to gain access.

					<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[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[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 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[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[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[I would like to explain whether or not it is better to put wp-config.php under a different name or in a different directory, and how to do this. Advantages of externalizing or renaming your WordPress wp-config.php The wp-config.php file contains very important information about the database connection. If this connection information is leaked to the outside, the database can be manipulated to create unauthorized users or rewrite WordPress content. In addition, a common vulnerability attack by hackers is to look into the contents of wp-config.php. To prevent this vulnerability attack, externalizing or renaming wp-config.php has security advantages. Reference (vulnerabilities #3 and #5 in the following article) The 6 most targeted plugin vulnerabilities in WordPress these days How to externalize or rename wordpress wp-config.php You can rename wp-config.php by following the steps below. 1. Rename wp-config.php Using FTP or a file manager wp-config.php → wp-config-secure.php (any name is fine, but it must match the name in step 2) 2. Rewrite the reading part of wp-config.php in wp-load.php The following two lines if ( file_exists( ABSPATH . 'wp-config.php' ) ) { /** The config file resides in ABSPATH */ require_once ABSPATH . 'wp-config.php'; Replace the following if ( file_exists( ABSPATH . 'wp-config-secure.php' ) { /** The config file resides in ABSPATH */ require_once ABSPATH . 'wp-config-secure.php'; The config file resides in ABSPATH */ require_ce ABSPATH . &#8216;wp-config-secure.php&#8217;; * The config file resides in ABSPATH */ require_ce ABSPATH . How to externalize? First, place the above wp-config-secure.php in a folder on the server above the folder where the HTML is located. Specify that folder with ../ to specify the hierarchy above. If you place it one level above if ( file_exists( ABSPATH . '../wp-config-secure.php' ) { /** The config file resides in ABSPATH */ require_once ABSPATH . '../wp-config-secure.php'; If you place it two levels up if ( file_exists( ABSPATH . '../../wp-config-secure.php' ) { /** The config file resides in ABSPATH */ require_once ABSPATH . '../../wp-config-secure.php'; Externalizing or renaming wordpress wp-config.php Disadvantages There are several disadvantages to the above customization that you should be aware of when updating WordPress. 1 When updating, WordPress will judge that there is no configuration file, and will generate a new wp-config.php file. 2 When updating, wp-load.php reverts back to the regular file and the renamed wp-config.php cannot be loaded, the site will be at the installation screen and the site will display poorly For this reason, you will be asked to externalize wp-config.php again each time you update. If automatic updates are enabled, the above error may be triggered at unexpected times. Is renaming wp-config.php recommended? We do not recommend renaming or externalizing wp-config.php except in special cases. Rather, we recommend that you take measures to prevent vulnerabilities that can be exploited by peeping into wp-config.php. We have a vulnerability database that allows you to easily perform a vulnerability check to look into the wp-config.php of plug-ins installed on your site.

					<description><![CDATA[We will explain about base64_decode and base64_encode, which are commonly found in WordPress malware, why this function often appears and how to recover this function. Why are base64_decode and base64_encode often included in WordPress malware? base64_encode is a method of mapping data such as strings to 64 different characters separated by a specific length. This makes it easier to handle various data as strings and record them in databases, and is used to prevent garbled or corrupted data. base64_decode is a function to decode it back. Data that would be misspelled if separated by a specific length is filled with == in base64_encode. Also, base64_decode and base64_encode are functions of PHP (the programming language in which WordPress is made), but in JAVASCRIPT (a scripting language that runs in a browser), the function names are btoa and atob, which are also often used for malicious code. It is also often used in malicious code. This encoded base64 string has the characteristic of making the original content difficult to recognize at first glance. For this reason, they are often used to obfuscate malware in order to prevent the code from being recognized as doing what it is supposed to do, or to avoid malware detection (pattern matching). Undo base64_encoded strings To undo base64_encode and see the contents, online services such as https://www.base64decode.org/ are useful. The following figure shows an image of a decoded string of malware base64_decoded. You can see that this string contains a setting that alters the WordPress HTACCESS file, making it impossible to log in. In the above example, the obfuscation could be removed with a single step of base64_decode, but some malware may use multiple base64_encodes, gzinflate (data compression), str_rot13 (string shifting), etc. in combination with the obfuscation process. (data compression) and str_rot13 (string shifting). Example str_rot13(base64_rncode(base64_encode(gzinflate(string to be hidden)))) Detect and remove base64-based obfuscated malware base64 obfuscation patterns can be detected with a high degree of accuracy using our [Free] WordPress: Malware Scanning &#038; Security Plug-in [Malware and Virus Detection and Removal]. Unlike PC viruses, WordPress malware has a huge number of patterns with extremely diverse obfuscation processes, and the WPDoctor WordPress: Malware Scanning &#038; Security Plug-in is designed to match this characteristic, with short and large number of detection patterns to scan thousands of files quickly. This plugin has been designed to be able to scan thousands of files at high speed with a short and large number of detection patterns. We hope you will find it useful.]]></description>

					<description><![CDATA[This page describes an infection case in which script malware was appended to a large number of posts in WordPress. Analysis of script malware that writes itself at the bottom of a large amount of post data The malware shown above is an example of malicious code (mainly a redirection hack that redirects the page to another site without permission) embedded in a post with a script tag. The trouble with this malware is that in some cases, this malicious JS code is written to thousands of WordPress posts. The malware is characterized by multiple strings of _0x3023 ( _0x562006 , _0x1334d6, etc.) and obfuscation of the JS code to make it impossible to tell what it is doing. Some parts of this code use a special way of specifying strings such as \x68\x74\x74\x74\x70\x3a\x2f\x2f\x75\x72\x6c\x63\x75\x74\x74\x74\x6c\x79\x2e\x6e\x65\ as unicode, and such The code can be converted to a readable string by outputting it at a site such as the following. https://playcode.io/javascript Decoding shows that this JS is sending the user to a redirect site URL that shortens any URL. How to deal with SCRIPT malware that writes itself at the bottom of large amounts of submitted data The malware itself writes the above malformed JS to thousands of posts in bulk. In addition, the fact that such modification of posts is possible means that hackers have access to the database, so it is likely that they have already taken over the privileges to rewrite and install files on the server through the installation of backdoors or other means. The measures to deal with this are roughly as follows. (1) Detect and remove malicious JS embedded in posts (2) Detect and remove the malware itself that writes malicious JS (*There is a possibility that the malware has already been deleted. (3) Detection and removal of backdoors that hackers use to infiltrate the server (*The backdoors may not exist as files, but may have been written to memory) (4) Inspection and elimination of vulnerabilities that allowed hackers to enter the server in the first place. (*1-4 can be done to some extent automatically by the malware inspection and disinfection plug-ins. Please use it if you like. To remove infected JS from thousands of posts, you can use Search Regex or other plug-ins that can replace strings in posts with regular expressions in batches.

					<description><![CDATA[This section will explain the most important WordPress security measures to be aware of. Causes of WordPress being hacked The above chart shows a bar graph of the most common causes of WordPress hacking, in order of most common. (According to WordFence, Inc.) Source: https://www.wordfence.com/blog/2016/03/attackers-gain-access-wordpress-sites/ It can be seen that plugin vulnerabilities are number one at nearly 60%, followed by brute force attacks (brute force attack on administrator passwords) at just under 20%. (In the case of Japan, since many Japanese-made themes are used and hosting is often done on shared servers, the numbers for the two statistics of Theme and Hosting are considerably reduced, with 70% due to plug-ins and over 20% due to brute force attacks, and these two factors can explain over 90% of WordPress hacking. Hacking is explained by 70% of plugins and more than 20% by brute force attacks). Sucuri also found that more than 90% of the vulnerabilities reported in WordPress are plugin vulnerabilities. Statistics show that the most important security measures for WordPress This shows that it is possible to prevent around 20% of hacking by simply making the password for WordPress administrator privileges strong. The password for WordPress administrator privileges should be a string of at least 12 meaningless characters, including upper and lower case letters, numbers, and symbols. This security measure will basically work all the time, as long as the site is SSL-secured, the password will not be leaked to the outside world via the Internet. Plugin vulnerabilities should be checked regularly. Hackers attack a vast number of WordPress sites using tools that exploit one prominent vulnerability after another (vulnerabilities that can easily be successfully hacked and the site&#8217;s files altered). If a plugin installed on your site has a well-known vulnerability, the hack will eventually succeed. In our experience, many sites with well-known vulnerabilities in their plug-ins are hacked within six months to a year. We test plug-ins for vulnerabilities every few months and update them if vulnerabilities are found. It is very important to regularly check plug-ins for vulnerabilities using security plug-ins, vulnerability databases, etc., and update plug-ins if vulnerabilities are found. It is best to regularly update WordPress, the plugin, and the plugin itself without checking for vulnerabilities, but in this case, the update may cause bugs in the site, or you may be asked by the creator not to update the plugin due to compatibility with the original theme. However, in such cases, it is best to update all plug-ins regularly. Even if a plugin is deactivated, it is often possible to exploit the vulnerability, so it is necessary to update or remove the deactivated plugins as well. WordPress sites have an image of being vulnerable to hacking, but the sheer volume of WordPress sites means that many sites have been hacked, and even simple security measures can greatly reduce the possibility of being hacked. Hackers will quickly give up on sites that cannot be easily hacked and move on to the next site, so with the above two measures, WordPress will almost never be hacked.]]></description>

					<description><![CDATA[The most important WordPress vulnerabilities to be aware of are Arbitrary file uploads and SQL injection. What vulnerabilities in WordPress are being targeted? When hacking WordPress, hackers use a haphazard method of hitting the easiest and most likely vulnerabilities it has on the site. Because WordPress is the world&#8217;s most popular CMS, with over 100 million sites, there are tools available to hack into multiple WordPress sites one after another to try to find the most prominent vulnerabilities. The two most easily exploitable vulnerabilities that hackers can exploit are arbitrary file uploads and SQL injections. What are Arbitrary file uploads and SQL injection? Arbitrary file uploads are vulnerabilities (link to vulnerability database) that allow arbitrary file uploads. Hackers often use this vulnerability as a starting point to install backdoors that allow them to alter files on the server, change WordPress settings to make it impossible to log in to the administration panel, or embed malicious code in the site content. SQL injection is a vulnerability (link to vulnerability database) that may allow the database to be rewritten. This one is less targeted than Arbitrary file uploads, but if an easily exploitable vulnerability is discovered, hackers may launch an intensive attack. There is an epidemic of hacker attacks. When Arbitrary file uploads or SQL injections are discovered in plug-ins with high penetration, an epidemic occurs in which the vulnerability is widely used. As mentioned above, hackers use tools to attack these vulnerabilities by obtaining a huge number of WordPress listings from search engines, etc. It does not matter how small your site is, as long as it is listed on a search engine, sooner or later it will be exposed to hackers&#8217; vulnerability attacks. It does not matter how small your site is, as long as it is listed on a search engine, it will sooner or later be exposed to hacker vulnerability attacks. In our experience, if a vulnerability is left unchecked, it is likely to be caught in a hacker&#8217;s net within six months to a year. It is important to stay on top of vulnerabilities! If you run WordPress, we recommend that all sites on your server be tested for vulnerabilities every few months. Click here to view our vulnerability database.

					<description><![CDATA[There have been an increasing number of cases of malicious JAVASCRIPT being embedded in all WordPress posts. Here is how to deal with this malware. A case in which a malicious JAVASCRIPT is embedded in a WordPress post, causing malicious behavior such as jumping to other sites when the site is accessed. JAVASCRIPT is a scripting language that runs on the browser and performs various functions on the site, such as dynamically rewriting pages, communicating behind the scenes, and animating the layout. Because JAVASCRIPT runs on the browser, even if an illegal JAVASCRIPT is embedded in a site, it cannot directly rewrite files on the server or install any files directly on the user&#8217;s computer, but it can lead the user to dangerous websites or create SEO links to other sites. However, it can lead the user to dangerous websites, or to the insertion of SEO links to other sites without permission. *Servers can also cause serious damage such as users installing malicious software on other sites, or being blacklisted by search engines as having malicious content, which can result in the site not appearing in search results. Example of malicious JAVASCRIPT being embedded in all posts on a site If a hacker takes advantage of a vulnerability in a WordPress site, such as a weak plugin or user password, to gain administrative privileges on the site, in many cases the database can be rewritten as well. Hackers use programs that rewrite the data of the site&#8217;s database submissions in one fell swoop, sometimes writing malformed JAVASCRIPT to thousands of submissions. The malformed JAVASCRIPT is often written at the bottom of the submission data, obfuscated as shown in the figure above. Reference What is the obfuscation process used in over 90% of WordPress malware? What to do when malformed JAVASCRIPT is embedded in a post When malicious JavaScript is embedded in a post, it is often discovered when PC virus detection software blocks access to the site, search results indicate that malware has been detected, or site users complain that they were redirected to another site or forced to download malicious software. In many cases, this is discovered when users of the site complain that they were sent to a different site or forced to download malicious software. Detection of malicious JS Such malicious JS embedding in posts can sometimes be detected by online services such as the following. Try checking for viruses in posts and top page URLs on such sites. Sucuri Site Check Online Malware Scanner For more powerful detection of malware from the inside, you can also use our Malware Detection Plug-in. Free WordPress:Malware Scanning &#038; Security Plugin [Malware and Virus Detection and Removal]. What if thousands of posts have malicious JAVASCRIPT embedded in them? If several thousand posts have malicious JAVASCRIPT embedded in them, it is difficult to remove them one by one by hand. In this case, we recommend the following methods. Roll back to the database before the contamination. Directly execute SQL statements (database processing instructions) that comprehensively disable illegal JAVASCRIPT strings in the database. *This [&#8230;]]]></description>

					<description><![CDATA[This section describes a web shell that can infect (or be installed by hackers) WordPress. What is a Web Shell? A web shell is a generic term for a type of backdoor that can be accessed and used via the Web (online). Think of a backdoor as a hacker&#8217;s way in on a server. In WordPress, web shells are often installed as PHP program files by hackers who take advantage of vulnerabilities to alter files on the server. Examples of web shells installed by WordPress tampering The above malware is a very simple web shell with file upload functionality. Web shells with complex functions may have the ability to execute OS commands, or have the ability to tamper with databases. Web shells that are obfuscated and placed in deep hierarchies are difficult to find. Web shells are often located in the top directory of a WordPress site, but since many of them can run in a single file, they are often located deep within the WordPress hierarchy, and their code may be obfuscated, making them difficult to find even when searching for strings such as &#8220;Shell. Shell&#8221; and so on. The easiest way to check for web shell installations is to use a plugin that comprehensively scans WordPress files for tens of thousands of malware detection patterns. If you like, you can use a free plugin to inspect and remove malware. Free WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal].]]></description>

					<description><![CDATA[This section describes injection attacks in which malicious content is inserted into WordPress pages. WordPress Content Injection Attacks The most common type of WordPress hacking is an injection attack, in which a site&#8217;s content or code is partially rewritten to insert malicious content, inducing users who visit the site to take actions not intended by the site&#8217;s creator. Examples of malware injected by hackers to induce unintended user behavior include the following Users are redirected to another malicious site instead of the page they were trying to view. Attempts to induce users to download malicious software Phishing attacks in which an unauthorized page is generated, registered with search engines, and users accidentally access the unauthorized page. Three types of injection attacks There are three types of injection attacks. Code Injection This is an injection attack that embeds (or controls the output of) a JAVASCRIPT or PHP executable program into an existing page. Page Injection This is an attack in which a malicious page itself is placed on the server to trap search engines and force users to access the page. Content Injection Content Injection is the insertion of illegal character strings or links into the content of a page (body, header, footer) to misdirect users. In these cases, content is often plugged in to give an SEO advantage. How do hackers inject malicious code or content into a site? In order for a hacker to perform an injection attack on a site, it is assumed that the site has already been successfully hacked and that the hacker has access to the database or files on the server that can be rewritten. Around 80% of all successful hacks are caused by site vulnerabilities or user password vulnerabilities. Hackers find vulnerabilities in the site, break through them, and then inject malware into files such as the following wp-config.php index.php wp-blog-header.php Theme functions.php header.php footer.php single.php Other plugins and theme settings stored in the database However, nowadays, the injection is not limited to the above files, but is often performed deep within the hierarchy in a variety of files that are executed each time a WordPress page is displayed. Finding and Removing Injected Files There are thousands of WordPress files, and it is very difficult to manually open each and every file to find injections. A plugin that exhaustively scans WordPress site files with nearly 20,000 injection (malware) detection patterns may be able to find and remove injections. Free WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal]. We hope you will use it!]]></description>
