What is AnarchyGrabber?

Discovered by MalwareHunterTeam, AnarchyGrabber is updated, malicious software that targets Discord users. Both original and updated versions steal users' accounts, however, the updated version is capable of evading detection by modifying client files. Cyber criminals distribute this malware on various hacker forums and via YouTube videos (links in the descriptions).

AnarchyGrabber malware

Research shows that the updated AnarchyGrabber malware version avoids detection through antivirus software by modifying Discord client's JavaScript files (it modifies client files by injecting code into them). AnarchyGrabber targets the "index.js" file, which is stored in the "%AppData%\Discord\[version]\modules\discord_desktop_core\" directory. Screenshots of original and modified Discord index.js client files are provided below. When a user launches Discord that has had its file modified by AnarchyGrabber, other, malicious JavaScript files are also loaded. When a user logs into Discord, those scripts immediately deliver the user's data (tokens) to a Discord channel controlled by cyber criminals. Stolen Discord accounts can lead to loss of all servers, contacts, direct messages, etc. Furthermore, cyber criminals can use hacked accounts to steal other accounts by spreading the same AnarchyGrabber malware, trick other users into installing malware (such as Trojans, ransomware and other malicious software) through direct messages, and so on.

There are many stealers on the internet. Some examples are Oski, ArkeiStealer and PoulightStealer. Commonly, these programs steal passwords, credit card details and other sensitive information that could be misused to steal accounts, identities, make fraudulent purchases and transactions, etc, however, this particular malware (AnarchyGrabber) targets only Discord users and is used to steal user accounts.

How did AnarchyGrabber infiltrate my computer?

Research shows that AnarchyGrabber is distributed through hacker forums and links in the descriptions of various YouTube videos that were uploaded by cyber criminals. More examples of untrusted file and software download channels are third party downloaders, free file hosting pages, freeware download sites and Peer-to-Peer networks such as torrent clients, eMule. Note that third party installers can also distribute malware. Cyber criminals commonly use spam campaigns, Trojans, software 'cracking' tools and fake updaters to spread malware. They send emails that contain malicious attachments (or web links that, if opened, download a malicious file) and hope that recipients will execute (open) them. In most cases, they attach Microsoft Office documents, PDF documents, archive files (ZIP, RAR files), executable files (.exe and others) and JavaScript files. Trojans are malicious programs that cause chain infections: when installed, they cause installation of other malicious software. Fake software updaters infect systems by exploiting bugs/flaws of outdated software or by installing malware rather than fixes/updates. Unofficial activation ('cracking') tools supposedly bypass paid activation of licensed software, however, they often install malicious programs.

How to avoid installation of malware

Irrelevant emails that contain attachments and/or links and are sent from unknown, suspicious addresses should never be trusted. Email contents should be opened only when you are sure that it will not cause damage (such as installation of malware). Installed programs must be updated and activated with implemented functions/tools designed by official developers. Third party tools should never be used - cyber criminals often employ them to spread malware. Furthermore, it is illegal to bypass activation of licensed software with unofficial ('cracking') tools. Software should never be downloaded from untrusted, unofficial websites, via third party downloaders or other channels of this kind. The same applies to installation through third party installers. Files and programs should be downloaded only from official websites and through direct links. Finally, all computers are safer when there is reputable anti-spyware or antivirus software installed. You are advised to scan operating systems for threats with this software regularly. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

Update 25 May 2020 - Cyber criminals have recently released a updated version of AnarchyGrabber stealer (now called AnarchyGrabber3). This version has been implemented with several new features and it is now capable of disabling two-factor authentication (2FA) in the Discord account, stealing plain-text passwords stored in the system and spreading other malware via Discord (private messages). The updated variant searches the system for various passwords saved in plain-text format. This is done to hijack victims' accounts on various websites, etc. By stealing victims' identities (accounts on social networks, emails, etc.), cyber criminals can generate revenue in various ways such as asking friends to lend money, sending them malicious files, and so on. AnarchyGrabber itself is now also designed to spread malware. AnarchyGrabber scans the list of contacts (friends) in the Discord application and messages those people online. The message contains a file or a link, baiting the recipient to open it. The chance of tricking someone is high, since people tend to recklessly open files/links sent by their friends.

To remove this malware we recommend using Malwarebytes for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
