					<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[There are various methods by which WordPress can be hacked, the most common of which is called an injection attack. This section describes these injection attacks. What is an injection attack? Injection is a Japanese word meaning injection. In other words, it is an attack in which a hacker embeds some malicious programming code or database data into a site. Injection attacks can be performed through vulnerabilities in plug-ins or brute force attacks in which a hacker repeatedly logs in to find out the administrator&#8217;s password. Reference How do hackers tamper with WordPress and embed malware? Types of Injection Attacks The following is a description of the typical types of injection attacks, in the order in which they are most often performed on WordPress. 1 Code Injection In this attack, a hacker embeds malware into a legitimate WordPress file. The most common files in which malicious code is embedded are index.php and wp-config.php, which are executed each time the site is viewed. For example, the following code is embedded and the malware is executed every time a user accesses the site. index.php /*sa6ahds6wr ← An identifier to check for the presence of the hacker's malicious code is also embedded @include(/var/www/.... /.6sada8dh.ico) ← Injection of the include portion to load the malware itself /*sa6ahds6wr Code injection is not necessarily written into a legitimate file, but may be installed as a single independent program on the server. This program may be a backdoor that serves as an entry point for hackers to re-hack, or it may have the ability to automatically reinfect or investigate the server. 2 SQL Injection WordPress generates websites with two types of data styles: real files, such as program files and HTML files, and data recorded in databases. An attack that illegally embeds or alters data in this database is called SQL injection. This attack involves creating users with unauthorized administrator privileges, writing unauthorized code in plug-ins or theme settings to be executed when the website is displayed, or embedding a large amount of Javascript code in content (posts) to cause users accessing the content to be sent to another This can be used for redirect attacks, for example, where a large amount of JavaScript code is embedded in content (posts) to send users who access the content to another site. 3 XML Injection This is an injection attack that has been on the rise in recent years, in which malformed URLs or pages are embedded in the XML of WordPress sitemaps, with the goal of hooking search engines. It causes a large number of pages that you do not remember to be trapped in the search results. In many cases, the malicious pages themselves are also embedded in the server, causing a variety of malicious pages to be displayed on the server. Detecting Injection WordPress injection attacks are often difficult to prevent. Reference Can a hacker attack on WordPress itself be prevented? However, simple measures can prevent most of them. Reference Five free WordPress security measures If you have already had an injection attack that has inserted malicious code [&#8230;]]]></description>

					<description><![CDATA[We will explain how to decontaminate malware using the WordPress:Malware Scan &#38; Security plugin [Malware and Virus Detection and Removal], which was created by WordPress Doctor based on his experience with numerous malware removal requests. IntroductionPrecautions for Normalware Removal Malware removal requires specialized knowledge. Inadvertent cleanup of malware can result in the worst case scenario, such as a site not displaying. If you do it by yourself, please pay special attention to the following points. 1 If the malware is a parasite that lives in the original WordPress files, only the tampered parts need to be carefully removed. 2 If the file is not a legitimate WordPress file, it is unlikely to cause a problem even if you delete the file itself, but in rare cases, the tampered file may be loaded by another tampered file. In this case, deleting the tampered file may cause an error in the caller file, and at worst, the site may not be displayed. If an error occurs, it is necessary to investigate the source file and delete the tampered file as well. 3 Database infections are often Javascript code embedded in posts or widgets. It is often possible to detoxify the malware by removing only the malware part of the content, without deleting the entire line. Scan for malware and tampering Install the WordPress:Malware Scan &#38; Security plugin [Malware and Virus Detection and Removal] and click the &#8220;Start Scan Now&#8221; button. Once malware is detected, a detection list will appear. The detection list shows two types: pattern match and confirmed diagnosis. If malware is indicated by confirmed diagnosis, it is almost certain that the site has been defaced. We will now explain how to get rid of the malware from this malware example. Actual plug-ins to get rid of malware Step 1 Check if this file is one of the files originally included in WordPress or in the plugin Malware may be contained in the form of a parasite in a legitimate WordPress or plugin file. If this is the case, deleting the file will likely cause problems with your site. Most commonly, this type of malware infects wp-config.php and index.php. This is because wp-config.php and index.php are convenient for hackers to have the malware run automatically, since it is executed every time the page is viewed. How can I be sure that the files are legitimate? It is possible to get a rough idea of whether a file is legitimate or not by checking the following points If the file is not legitimate 1 No &#8220;wp-&#8221; mark 2 It does not have class-. 3 Not index.php 4 Files with meaningless random strings and .php or .ico extensions 5 File name that looks like a misspelling of a legitimate WordPress file, e.g. xmlrrpc.php Otherwise, you can also check if a file is legitimate by actually downloading the core WordPress file or plugin and see if it is in the detected file name and path. Step 2: Eliminate parasitic-type malware View the file from the View Edit File button. Malware code is obfuscated and reduced to [&#8230;]]]></description>

					<description><![CDATA[This page explains the cause and how to target a string starting with @include that suddenly appears at the top of wp-config.php or index.php in WordPress. @include at the top of wordpress wp-config.php or index.php What is this? Simply put, this is often a loading program for malware to run on all pages where the site has been defaced by hackers and this description allows users to view the site. The loading code for this malware, which is generally very common, is as follows /*88783*/ @include "\057var/\167ww/the\155e/.8\0719417\0629.ic\157"; /*88783*/ The first line and the random string of characters/numbers sandwiched between the /* in the last line are keys to confirm the existence of the malware to embed the same tampering again when this tampering is removed. In the second line, following @include, a program is written to read and execute the malware itself, but it is obfuscated so that its contents cannot be seen as is. You can un-obfuscate it here. Once the obfuscation is removed, you will see that the full path to the malware is described as shown below. /*88783*/ @(include "/var/www//theme/.89941729.ico"); /*88783*/ How to deal with this malware 1 Unobfuscate the relevant string and find the path to the malware itself. 2 Delete the malware itself from the server using ftp software, etc. (We recommend that you do a full backup of your site). (We recommend that you do a full backup of your site before proceeding) 3 Remove the tampered parts at the top of wp-config.php and index.php and re-upload them to the server. Also, the presence of this tampering is most likely another tampering on the site, a backdoor (a gateway for hackers), or a vulnerability in a plugin or password. Be sure to check your plugins for malware and vulnerabilities. 4 Remove vulnerabilities and other malware and backdoors as described above. 5 We also recommend that you change the password for the administrator user Our malware plugin is capable of detecting nearly 7,000 types of malware, but some will inevitably be missed. For a complete cleanup, we recommend that you have a professional decontaminate your system.]]></description>

					<description><![CDATA[If you find the following code in some index.php files included in your WordPress site, you are infected with malware and should be careful. Malware that alters index.php and is carried out no matter which page of the WordPress site is loaded If the index.php file contains @include &#8220;\057v\151r\164u\141l\0571 and the include statement sandwiched between comments such as /*963c2*/ above and below, the code is for loading the malware itself. This code is obfuscated, and when unobfuscated, it will look like the following string. @(include "/virtual/.24b5f368.ico");. This code loads the malware body, .24b5f368.ico, and causes the site to perform malicious actions, such as redirecting the site to another site. The random string of /*963c2*/ comments included at the top and bottom are for hackers to see if they have already embedded malware in that file. Coping Methods If you find such a file on your site, immediately delete the line containing @(include &#8220;/virtual/&#8221; and the random string comments above and below, and re-upload index.php. Additionally, We also recommend that you run a site-wide file and database malware scan with the [ Free] WordPress: Malware Scanning &#038; Security Plug-in [Malware and Virus Detection and Removal].

					<description><![CDATA[We will provide an explanation of the malware that disguises itself as an ico file, which has recently been on a rampage, and introduce countermeasures. Malware disguised as ico files infecting WordPress If you are experiencing symptoms such as WordPress redirecting to other sites without your permission, mysterious strings being displayed in the header or footer of your site, or JS files that you do not remember incorporating being loaded, please be careful. If you find the following code in your WordPress file, you are infected with a type of malware that disguises itself as an ico file. @include "\057usr/\150ome/random strings.ico";. This short write-up, by the hacker, is an instruction to load other malware with the .ico extension in a specific directory, albeit obfuscated. It is generally found in files such as the following. ● wp-config.php index.php in any folder header.php, footer.php, single.php, page.php in the theme folder Reference article Learn how hackers rewrite (alter) files on your WordPress site to increase security! Ico file, the main body of malware Ico files are essentially image files, but since many malware detection plug-ins exclude them from detection, hackers disguise them as Ico files to hide the PHP program code so that the files are not detected. The loading process by @include executes the contents of the Ico file as a program to perform the unauthorized activity the hacker wants to perform on the site. The contents of an Ico file generally look something like the following and are further obfuscated so that it is not obvious what the hacker is doing at first glance. $_gow5jau = basename/*cab6*/(/*a7jhy*/trim/*fs4*/(/*1x*/preg_replace/*s2ot*/(/*9z*/rawurldecode/*7a*/(/*n*/"/\(.*$/"/*i*/)/*fi40*/, '', __FILE__/*pz2or*/)/*5*//*sq*/)/*sdxc*//*tz*/)/*rkadc*/ ~ followed by a string The activities of these programs vary widely, but they are often unauthorized redirects, such as redirecting users to a site or replacing links on the site so that they go to another site. Detection and Elimination of Malware Disguised as Ico Files With WordPress Doctor Malware Scanner &#38; Security, we can detect both the tampering that is loading malware in @include and the body of malicious code disguised as an Ico file. What to do if the @include statement is detected Since this write is for hackers to read the body of the malware Delete the @include ~ ; (a line starting with @ and ending with 😉 with a text editor, etc. and save it again. What to do if the malware body with Ico extension is detected This file does not exist in WordPress. If you open the file and find that it contains obfuscated code, you can delete it as is.]]></description>
