					<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[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[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[We will explain how to batch delete malformed JS that infected the database in WordPress. Malicious code infecting the database We may find JAVASCRIPT code that infects databases, such as plug-ins that can detect database malware. In many cases, these malicious Javascripts are embedded in thousands of posts, and it is difficult to remove them one by one by hand. In this case, you can use a plugin to remove them one by one with regular expressions. Bulk removal by pattern matching with regular expressions A regular expression is a method to search for strings in a more meta way. For example, the following regular expression can match a string of 10 or more numbers. /[0-9]{10,}/ If you create a regular expression that matches and replaces the aforementioned illegal JAVASCRIPT, and execute the regular expression on all posts, it is possible to remove the illegal JAVASCRIPT at once. If you observe the malformed code carefully, you will see that it starts with 　&#60;script&#62;$mWn= and ends with &#60;/script&#62; without &#60; in between. This regular expression can be expressed as follows /&#60;script&#62;\$mWn=[^&#60;]*&#60;\/script&#62;/ The $ and / are backslash escapes because they are meaningful expressions in the regular expression. The [^&#60;]* means as long as the string is followed by a string that is not 　&#60;. *It is possible to create regular expressions by experimenting with them at this site. You can see that it matches within the correct range. Regular expressions to remove malformed JS infecting WordPress databases Next, we will use regular expressions to remove the malformed JS embedded in posts and other content. If this removal process fails, important database information may be lost, so we recommend that you make a backup of your database before removal. 1 Install the Search Regex plugin that allows you to replace the database with regular expressions. 2 Go to Tools→Search Regex and perform the replacement process using regular expressions. First, configure the regular expression as shown in the figure below, and check that it matches the invalid code properly as no operation. Next, set the operation to replace the entire string, add a single space character to the replacement string, and execute the replacement. This completes the bulk removal of the invalid JS. Please note that removing malware from the database alone may not solve the problem! The fact that malware has been embedded in the database means that hackers have already obtained the database search permissions through some vulnerability, and it is highly likely that other malware programs have been installed on the server. It will be necessary to inspect for other malware and close the vulnerabilities that allowed the hacker to enter the database.]]></description>

					<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 page explains how to set Content-Security-Policy (CSP) in WordPress to prevent unauthorized execution of externally loaded JAVASCRIPT. What is Content-Security-Policy? Content-Security-Policy is used to specify conditions for JAVASCRIPT, font loading, Iframe execution, etc. in the communication header of the page data. The browser reads this specification and executes external JAVASCRIPT, etc. according to that setting, thus acting as a bulwark to prevent users from executing JAVASCRIPT from malware-infected sites. If WordPress has the appropriate values in Content-Security-Policy, it can prevent users from executing malicious JAVASCRIPTs on the page in case the site is infected with malware or other vulnerabilities, thereby minimizing the damage to users. This can minimize the damage to the user. In this article, we will explain how to configure Content-Security-Policy to prevent unauthorized external loading scripts from being executed. How to embed Content-Security-Policy in the WordPress header The code below is for outputting the Content-Security-Policy JAVASCRIPT execution settings in the header section of WordPress. It works by putting it in your theme&#8217;s functions.php or other file. WordPress function my_add_security_headers($headers) { $headers['Content-Security-Policy'] = "script-src 'self';"; return $headers; } add_filter('wp_headers', 'my_add_security_headers',1,1); The &#8216;wp_headers&#8217; filter allows you to add Content-Security-Policy to the WordPress header output. &#8220;script-src &#8216;self&#8217;;&#8221; is the strictest setting, allowing only .js files on its own domain to load. With this setting, many sites will be limited to loading JAVASCRIPT, which can cause site display and functionality malfunctions, so this setting can be lax if necessary. script-src 'self' 'unsafe-inline' 'unsafe-eval'; would also allow inline JAVASCRIPT and eval functions. script-src 'self' 'unsafe-inline' 'unsafe-eval' *.googletagmanager.com *.google-analytics.com *.googlesyndication.com *.gstatic.com *. google.com wordpress.com *.wp.com;. would also allow Google Tag Manager, Google Analytics, other Google ads, and Jetpack-related wordpress.com JAVASCRIPT embedding. In most cases, this setting will not cause any problems with the JAVASCRIPT-related settings in Content-Security-Policy. (** means that any string matches the condition. If you are using other external affiliate or access analysis scripts In this case, you will need to add the domain of the site that loads that external JAVASCRIPT to the end of the script-src setting in Content-Security-Policy. Example *.example.com script-src 'self' 'unsafe-inline' 'unsafe-eval' *.googletagmanager.com *.google-analytics.com *.googlesyndication.com *.gstatic.com *. google.com wordpress.com *.wp.com *.example.com;. Prevent your site from being infected with malware or exploited for vulnerabilities. Content-Security-Policy is only a bulwark on the user side; it is also important on the operational side to prevent malware infection or, if the site is infected with malware, to remove the malware and prevent vulnerabilities from occurring on the site. We also recommend the use of security-related plug-ins that provide malware scanning and removal, vulnerability scanning, and security enhancement functions.

					<description><![CDATA[There has been an increase in the detection of malware embedded in databases via WPCode &#8211; Insert Headers and Footers. This malware will be explained in detail. What is WPCode &#8211; Insert Headers and Footers plugin? The WPCode plugin is a plugin that allows you to embed arbitrary HTML and JAVASCRIPT code into headers and footers. It is often used to add CSS to a site&#8217;s design or to use Google&#8217;s access analysis tags. However, this plugin can also embed PHP programs. While it is generally not possible to embed and run PHP programs in databases, the WPCode plugin allows hackers to embed malware in databases that many malware scanners do not inspect. Malware embedded in WPCode The WPCode plugin is not vulnerable, and a hacker could first exploit other vulnerabilities, gain administrative privileges to the site, add the WPCode plugin to the site, embed malware as a snippet of the WPCode plugin on the site, and then exploit the WPCode plugin to gain access to the site. and also embeds CSS in the snippet that hides the WPCode-related UI in the admin panel as if the WPCode plugin were not installed on the site. Database tables in which malicious code is embedded wp_options, wp_postmeta, wp_post table, etc. Key for options table wpcode_snippets Example of CSS code to hide the fact that an illegally embedded WPCODE plugin is installed function fix_style() { echo '&#60;style&#62;'; echo '#toplevel_page_wpcode { display: none; }'; echo '#wp-admin-bar-wpcode-admin-bar-info { display: none; }'; echo '#wpcode-notice-global-review_request { display: none; }'; echo '&#60;/style&#62;'; } This code will erase the display of the menu and plugin list in the Wpcode admin screen, which was introduced illegally by the hacker. Therefore, the WordPress administrator will be unaware that WPCODE has been installed without their permission when they log in to the site. Malware embedded in WPCODE In addition to the above, WPCODE snippets also contain malware code that can generate malicious users, retrieve malicious code from other sites and write it to the server, JAVASCRIPT code that redirects the site to another site, write links to the site content without permission, and other functions. This includes malware code. Response to malware embedded in WPCode Such malicious snippets can be detected with the [Free] WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal]. If a rogue WPCode snippet is detected, it will be erased line by line. (Since the wp-option table, in which malicious WPCode snippets are often embedded, is a table in which various WordPress configuration data is written, we recommend that you take precautions and back up your database when deleting database rows). You can also check if WPCode is installed by itself by connecting to the server using FTP software and looking for the folder insert-headers-and-footers in the wp-content/plugins/ folder. You can also check for the presence of WPcode&#8217;s incorrect code in the database by using database connection software such as phpmyadmin or adminer and searching the database with the following query (which is a style sheet that hides WPCODE from the admin panel). #toplevel_page_wpcode { display: none]]></description>

					<description><![CDATA[Here are some sites online where you can scan your WordPress output for malware (not a vulnerability scan) to see if there is any malicious code mixed in with the HTML of your site. Sucuri SiteCheck https://sitecheck.sucuri.net/ Sucuri SiteCheck is a fairly old site that allows online malware scanning. You can scan any page by entering its URL. The site pretends to be accessed from Google and scans for malware, so it can detect malware that only appears in Google search results. Quttera https://quttera.com/website-malware-scanner Like Sucuri SiteCheck, Quttera allows you to scan for malware by entering the URL of any page. However, free malware scans are queued and performed in order, so it may take some time for the scan to complete. WP Doctor Online Malware Scanner https://malware-scan.website-malware-removal.com/ WP Doctor Online Malware Scanner is an online malware scanning site with malware detection patterns we have collected from over 1 million malware files. You can scan for malware by file code, file upload, or URL. Limitations of Online Malware Scanning Online malware scans can only scan HTML and JAVASCRIPT code that is output as a site page. However, more than 99% of the malware that infects WordPress resides on the server as PHP programs that run on the server. It is therefore important to note that online malware scans can only scan the results of malicious code generated by such malware. Disadvantages of Online Malware Scanning Since the malware itself is not scanned, even if it is detected, it is often not known where the malware itself is located. Malware detection is limited (spam-sending malware and backdoors, which are malware that hackers use to gain entry into your computer, cannot be detected). ・Malware with various malicious code expression conditions, such as only when accessing a smartphone, or when accessing a site via a search engine, or when a site is accessed by a browser, are often undetectable. Because of the above disadvantages, we believe that the detection accuracy of online malware scanners is strong against redirect hacks, etc., but is quite poor in detecting malware that infects servers as a whole. For more accurate malware scanning, we recommend using a plug-in type malware scanner that can scan the WordPress program itself comprehensively from the inside.

					<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.

					<description><![CDATA[We will explain how to restore (decode) a malware file that has infected WordPress. Obfuscated malware files The program files of malware infecting WordPress are often unrecognizable at first glance, as shown in the figure, because it is difficult to tell what they are processing. This process is called obfuscation, and it is the process of processing or rearranging the order of program strings to make them difficult for humans to read without changing their behavior. Obfuscation is performed using a variety of software (obfuscation programs and scripts are often distributed for free on GitHub and elsewhere). Hackers obfuscate files to avoid detection of malware and to prevent exposure of which sites and email addresses they are connecting to (and sending data to). Restore obfuscated PHP and JAVASCRIPT files to their original, readable code Although it may not be possible to reproduce the complete program, there are web services that can de-obfuscate such files. https://malwaredecoder.com/ http://php-decoder.site/ https://www.unphp.net/ Manual compounding is also possible in some cases. For example eval (base64_decode('string ), you can turn the executable function called eval into an output function called echo to see what the malware code was trying to execute. echo (base64_decode('string We hope this helps.

					<description><![CDATA[This section explains what to do if you do not know the location of infected malware or if you cannot find it. I have symptoms of malware, but I don&#8217;t know or can&#8217;t find where the site has been tampered with. When WordPress is tampered with and malware (malware) is embedded, the following symptoms often occur. When you visit the site, you are redirected to a different sweepstakes site, a fake login page, or a fake software distribution site. When you click on a link, you are redirected to a different site. Virus detection software indicates that the site is infected. When I visit the site from a smartphone or Google search results, I am redirected to another site without my permission. Unable to log in to the administration screen, or unable to access some of the administration pages even if able to log in. Unnecessary advertisements are embedded in the page, or links are inserted in the page that I don&#8217;t remember adding. However, hackers may cleverly hide the malware themselves, and it can be very difficult to find the source of these symptoms (where in the HTML or WordPress PHP program is it located?) ). Here is how to deal with these cases. Solution 1: Search for malware by using malware scanning plug-ins. Check for malware mechanically with a plugin that performs an internal inspection of malware from the code. [Free] WordPress:Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal]. The free version of the above plugin can detect malware embedded in files and databases up to the point of plugin installation on WordPress. (To keep your malware detection patterns up-to-date, you need to purchase the paid version.) However, since malware is constantly evolving to avoid pattern detection, the plugin alone may not be able to detect all of them. Solution 2 Update Updating WordPress and plug-ins replaces the files with legitimate files, which may result in the overwriting of malware parasitic on legitimate files. We also recommend that you update to a version that closes the vulnerability that allowed the malware to enter the system. However, updating will not eliminate malware that exists independently of legitimate files or malware in configuration files (files that are not replaced by updates). Solution 3 Visual inspection of susceptible files Visual inspection of files in which WordPress malware is commonly embedded is also an effective method of disinfection. When hackers tamper with WordPress, they most often target a group of files that are executed whenever WordPress is run. Examples. wp-config.php index.php .htaccess wp-blog-header.php Theme functions.php header.php footer.php in theme single.php in your theme .js (JAVASCRIPT files) included in the theme and so on. Download these files via FTP, open them with a text editor, and visually inspect and remove them. Solution 4: Check for malware infection on other sites on the server. Many of today&#8217;s malware reads the structure of all files on the server and spreads the infection to folders on other domains hosted on the server. If the malware resurfaces soon after the infection has been removed, it is [&#8230;]]]></description>

					<description><![CDATA[There are two types of malware infecting WordPress, one made of javascript and the other made of php. What is javascript and PHP? Javascript is a scripting language included in WordPress themes and plugs that is executed in the browser only when a user accesses the site. Malicious javascript scripts that run in the browser cannot rewrite files by themselves and can move users from the browser to another site without their permission, or force them to enter login information that displays an incorrect screen for a fake user, etc. User. php is the programming language in which wordpress is created and has very much greater privileges than JavaScript. This means that php malware is the main cause of the creation and output of the aforementioned malicious javascript programs. Danger level of malware php malware > javascript malware (malicious scripts) Removal of javascript and php malware Since php malware is the cause of the aforementioned malicious javascript output, it is first necessary to remove the php malware. However, WordPress generally has thousands of legitimate php programs, and it is extremely difficult to find php tampering and malware among them. In this case, the easiest way to get rid of malware is to get professional help or use a plugin that will mechanically inspect for malware. Free] WordPress: Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal Get rid of javascript malware that plugs vulnerabilities in your site Eliminates php malware and then also eliminates javascript malware that is being generated. However, if the vulnerability of the site that allowed the hacker to enter in the first place is not plugged, the site will be reinfected from that vulnerability. Make your wordpress admin password strong. Inspect and remove the fraudulently generated WordPress administrator. Update old plugins and other vulnerabilities that have not been updated for more than a few years of updates. Malware may have spread from other sites on the server, so if there are other sites on the server, perform malware inspection and removal updates for them as well.

					<description><![CDATA[Malware that infects WordPress is quite different from ordinary computer viruses. Here is an explanation of what makes them different. Cannot infect PCs and MACs directly The malware that infects WordPress is written in the same PHP program (or JAVASCRIPT) that WordPress runs on. This PHP program is only executed by the server software. (In the case of JAVASCRIPT, it will only run on browsers with strict security restrictions.) Therefore, unlike software that can infect your PC or MAC, you will not be infected with a computer virus that can run on your PC or MAC OS simply by accessing the site because the server has been compromised by malware. (However, if WordPress malware prompts users to download or install malicious software, or sends users to another malicious site where they download and execute a virus, the PC or MAC may also be infected.) Directly written to the server remotely over the network While computer viruses often require some action on the part of the user, such as executing or installing the program, WordPress malware is written remotely and directly to the server by a hacker through a vulnerability in the site. Most program vulnerabilities are caused by the inadequacies of the creator of the plugin, theme, etc. Generally, when a vulnerability is discovered, the creator plugs it and releases an update. Therefore, it is important for security reasons to keep WordPress up-to-date. Parasitic in legitimate files While computer viruses are often stand-alone executable binary software, many types of malware that infect WordPress are parasites that write into legitimate files on WordPress. Therefore, if you delete the malware-infected files, the functionality of the legitimate WordPress files will also be erased, which may lead to site malfunctions. Unusually large number of malware code variations Unlike computer viruses, which are spread by a single virus or a large number of different variants, malware that infects WordPress has a much larger number of variations in its code. It can be different from site to site, or even from file to file. For this reason, the malware scanning plug-ins we develop do not detect individual malware in a categorized manner, but rather detect tampering from a short and extensive set of malware patterns. We hope you will take advantage of the free malware inspection detection in the past. Free] WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal]. Purpose of Malware The purpose of computer viruses is to steal personal information of users of that computer, encrypt files and demand money, etc. In some cases, individuals are harmed, but in the case of WordPress malware, such as increasing the number of hits or search rankings of any given site, malicious Many types of malware induce users to take actions on the web. In addition, its targets are often intended to cause widespread and shallow damage or profit for a large number of users surfing the Web, rather than for individual users. We believe that WordPress malware and tampering countermeasures are necessary in accordance with these characteristics.]]></description>

					<description><![CDATA[We will explain how an infection (tampering) with the WordPress database can cause the files on the site (server) to be tampered with. Types of WordPress Malware Infection WordPress consists of three major types of data: a group of program files, uploaded data such as images, and a database where content text and various WordPress settings are recorded. Of these, the program files are the most frequently tampered with, and in our experience, more than 90% of the time, the program files are tampered with or incorrect files are added. Cases of unauthorized data being written to the database are rare among WordPress hacking victims. What kind of malware infects WordPress databases? Database tampering is done through SQL injection attacks, backdoors, and brute force attacks that take advantage of plugin vulnerabilities. Through these attacks, the WordPress database may be tampered with and unauthorized data may be written to it. There are three main types of database tampering (1) Content tampering WordPress content is embedded with Javascript code that creates unauthorized redirects (users who visit the site are automatically redirected to other sites) or advertisements. (2) Tampering with configuration data Some configuration data of plug-ins or themes are tampered with, and the configuration data is output to the homepage, causing unauthorized redirects, unauthorized search engine registration, or other unintended actions to the site. (iii) Addition of unauthorized users WordPress users have IDs and passwords recorded in the database. This user can be created by a hacker by tampering with the database, allowing the hacker to log in as an administrator at will. Does database tampering cause tampering with WordPress files? Since only data can be recorded in the database and not executed as a program on the server (data in the database can only be retrieved), database tampering can directly cause tampering with files on the server, installation of backdoors or other server file tampering or folder structure on the server, such as by tampering with files on the server or installing backdoors. However, if an unauthorized administrator user is created as described in (3) above, a hacker can log in to WordPress with administrator privileges, which means that he/she can alter any files, install backdoors, or do anything else. Malware such as WordPress database tampering and file tampering can be scanned and removed with our plug-ins. Many of the features are free of charge, so please feel free to use them. Free] WordPress:Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal]. We also recommend that you regularly check your WordPress site for unauthorized users.]]></description>

					<description><![CDATA[This section describes phishing that displays a fake Google login screen on a WordPress site. Displays login screens for various services and steals users&#8217; login IDs and passwords Hacking and stealing login information by altering WordPress and sending the user to a different site (redirect), displaying a fake login screen for a fake company, and then stealing the user&#8217;s login information when the user mistakenly enters the wrong information is called This is called phishing. Various phishing sites have been identified, but phishing is most often performed on the most popular services. Google login screens and widgets Microsoft login screens and widgets Paypal login screens and widgets Various foreign banks&#8217; login screens (we have not confirmed any phishing sites for Japanese banks&#8217; login screens at present) Your website displays a login screen that you do not remember creating. If your website displays a login screen for a well-known service that you do not remember creating, it is possible that your site has been tampered with. If a visitor to your site enters his or her login information on this fake login screen, the ID and password could be sent to hackers and the user could be seriously harmed. Embedding such a fake login screen is easy for hackers because they can simply copy the HTML code or image and make it look exactly the same as the legitimate screen. To tell if a site is a phishing site, it is important to look at the URL of the site you are currently accessing or to basically not trust the login widget if it appears on another site that you do not trust, such as Google. Detecting Phishing Malicious Code If your site embeds a fake login screen or sends users to an unauthorized site that hosts a fake login screen, there may be malicious code embedded in your company&#8217;s site. This code can be cleverly hidden deep down or obfuscated to make the code difficult to read, making it very hard to find. index.php (in the top WordPress directory or in the theme). Example of obfuscated code *See also the following for files most likely to be tampered with 10 files in which malformed JAVASCRIPT code is embedded when WordPress is tampered with This kind of unauthorized tampering can be detected and removed by security plug-ins. If detection and disinfection is difficult, we also recommend that you contact a technician with expertise in the field.]]></description>

					<description><![CDATA[Here are some characteristics of malware files that can infect WordPress. If such a file is found on the server, it is most likely malware. Random file names or file names that are slightly different from the core WordPress files Some malware files infecting WordPress are embedded in legitimate files, while others exist on their own. In the case of malware that exists by itself, it is often installed as a file with the following random string of characters that is not originally in the legitimate WordPress or plugin files. hfyrju.php .7tyuguijs789.ico They are also sometimes installed with slightly different file names from those included in WordPress to avoid detection. wp-conflg.php ← The original file name is wp-config.php wp-signin.php ← original file name is wp-signup.php Obfuscated Obfuscation is a method of making PHP and Javascript source code difficult for humans to read so that they cannot quickly see what they are doing. More than 99% of malware files are subjected to this process. (Some themes and plug-ins are obfuscated for security reasons or because they are licensed programs, so obfuscation does not necessarily mean they are malware.) However, if the malware is of the type that parasitizes legitimate WordPress core files and is obfuscated, the possibility of infection is very high. (This is because WordPress core files do not contain obfuscated programs.) Examples of obfuscated malware code *Obfuscated program files may be unobfuscated with https://php-decoder.site/. Contains the string base64,eval The most common functions used in malware are the saw base64 and eval functions. base64 is often used for the obfuscation process described above, and eval is a function that executes text as a program, so it is often used to actually execute the strings in the obfuscated program. If a program contains one or more of these two strings, it is highly suspected to be malware. include statement that reads the file with the full path in one line In this case, the malware would look like the following @include("/var/www/...... /.da6t6gufjid79as.ico") This string may be obfuscated. In general, WordPress is designed to work on all servers, so such a full-path include (read statement) is never included in the program. Therefore, if code containing the full path is found on the server, a malware infection is suspected. Loading of external scripts that you do not remember being included in header.php or footer.php Since header.php and footer.php included in the theme are loaded on every page of the WordPress site, they are often used to plant malicious code for redirect hacks that force users who access your site to an unauthorized site. If your theme&#8217;s header.php or footer.php is loaded with external scripts that you do not recognize, it is possible that it has been tampered with and the malicious Javascript code has been embedded. The above malware can be scanned for malware in the server at once with the plugin Free] WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal]. You can use this plugin to scan your server for malware. Please try it.]]></description>

					<description><![CDATA[The most common vulnerability in WordPress is called Cross Site Scripting (XSS). We would like to explain about this vulnerability. What is a cross-site scripting vulnerability? Simply put, cross-site scripting is a vulnerability that allows an arbitrary JAVASCRIPT to be executed on a browser. A JAVASCRIPT is a program that is executed on the user&#8217;s browser, not on the server, and controls the site&#8217;s movements, communicates behind the scenes to bring data, etc. However, writing files and accessing the user&#8217;s computer are heavily restricted Script. Therefore, even if there is a cross-site scripting vulnerability, the data on the WordPress site&#8217;s server will not be tampered with. What can a cross-site scripting vulnerability do? If a user clicks on a link that contains malicious JavaScript code in cross-site scripting, an arbitrary JavaScript can be executed on your site. In this case, users may suffer the following damage Users will be directed to malicious site advertisements or fraudulent sites. The user&#8217;s login information (information stored in the browser&#8217;s cookie) on your site is sent to the hacker. (For this reason, XSS is especially important to be aware of on sites where users log in.) The login information of the WordPress administrator is sent. (However, this login information is encrypted, so it does not immediately leak the administrator&#8217;s login. Please refer to this article ). XSS is used as a springboard for spam mail and DDOS attacks. XSS does not have an email sending function, but it is possible to make a contact form on a WordPress site work with XSS. (* XSS itself does not have an email sending function, but it is possible to make a contact form on a WordPress site work with XSS. How to prevent cross-site scripting vulnerabilities? The following measures are effective in preventing the use of cross-site scripting vulnerabilities. Update plug-ins and other software to eliminate the vulnerability. Set up a Javascript execution policy called Content Security Policy. Reference What is Content Security Policy CSP? How to set it up in WordPress For WordPress malware and vulnerability scanning, please refer to the following Free WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal] if you would like to use it.]]></description>

					<description><![CDATA[The most common type of WordPress tampering these days is the hacking of WordPress sites for SEO purposes. We will explain this SEO spam. Typical Symptoms of SEO Spam SEO spam is a vulnerability in WordPress or a weak password for the administration panel that is exploited by brute force to seize administrative privileges and execute altered files on the WordPress site. Typical symptoms of SEO spam include the following The sitemap is rewritten, and pages from e-commerce sites are registered in search results that the user has no knowledge of. A large number of the fraudulent pages are actually placed on the server. When you access the site, you are redirected to another site. Only visitors coming from search results are redirected to a different site. Links to specific sites are inserted in the header or footer without permission. Incorrect keyword lists are inserted in the header or footer. Illegal advertisements or pop-ups are inserted into the site Illegal JAVASCRIPT code is inserted into a post, or an unidentified page is posted without permission. Purpose of SEO Spam The reason hackers deface sites and install malware to perform SEO spam is to profit from the influx of traffic via search engines and the search results themselves. The objectives of SEO spam are as follows 1 Increase traffic to any given site Forcing access to a site to skip to another site or registering a rogue page or sitemap in search results because the hacker gains some profit by increasing access to that rogue site. 2 Increase the search ranking of any given site Search engines determine rankings based on a system whereby if a site has more links from external sites, it is rated higher and moved up in the search rankings. For this reason, by tampering with WordPress and adding links on your own, you can aim to increase your search ranking. If there is a link near the keyword for which the search ranking is to be increased, the search ranking of the linked page will be increased according to the nearby keyword. This is the reason why keywords are illegally embedded by hackers. 3 Affiliate Hackers profit by tampering with WordPress sites to illegally obtain advertisements for affiliate purposes and link clicks on the site. Eliminate SEO spam WordPress defacements are often hidden so deep in the system these days that it is often difficult to find them all by hand. However, the trend is that tampering is often embedded in files that are executed whenever any page on a WordPress site is accessed. Examples would be the following files index.php wp-config,php header.php of the theme theme&#8217;s footer.php theme&#8217;s functions.php theme&#8217;s single.php Reference 10 files in which malicious JAVASCRIPT code is embedded when WordPress is tampered with If you are looking for the files visually, download the files from the server, check the above files first, and if there is malicious code embedded in them, carefully remove and re-upload only those parts. SEO spam can be detected and removed mechanically from the database and files. Free WordPress:Malware Scan [&#8230;]]]></description>
