Bloody Stealer virus removal guide

What is Bloody Stealer?

An information stealer is a type of malware that cybercriminals use to gather sensitive details, for example, information related to the victim's credentials (usernames, email addresses, passwords), financial information like credit card details, bank account numbers, etc. Bloody Stealer (BloodyStealer) is an information stealer that is for sale on a hacker forum. It has two subscription plans: monthly ($10) and lifetime ($40). It is common that information stealers can run on the system without being noticed/detected by the installed antivirus software.

Bloody Stealer malware

It is known that Bloody Stealer steals information such as cookies, passwords, autofill forms, and maps saved on browsers. Also, it steals computer information (e.g., details about the installed hardware and software, and other information), session data from Bethesda, EpicGames, GOG, Origin, Steam, Telegram, and VimeWorld clients, text (.txt) files stored on a desktop and uTorrent files. Additionally, Bloody Stealer can capture screenshots. This malware sends collected data to the attackers behind it through Telegram. Therefore, users who would have this information stealer installed on their computers could lose access to various email, social media, or even banking accounts (and the clients mentioned above) and have stolen accounts misused to make fraudulent purchases, transactions, steal identities, distribute malicious software (including the Bloody Stealer, ransomware, cryptocurrency miners, etc.), spread spam, or for other malicious purposes. It is important to mention that by having access to certain accounts or clients, cybercriminals may try to use their login credentials to access other accounts since many users use the same credentials for multiple accounts.

More examples of malware classified as information-stealing malware are Cypress, X-FILES, and CopperStealer. As mentioned in the first paragraph, malware of this type mainly targets financial information and login credentials (like usernames and passwords). It is worthwhile to mention that information stealers can function as keyloggers - they can record keyboard input (log data entered with the keyboard connected to the infected machine). Some stealers can be used to execute distributed denial-of-service (DDoS) attacks.

How did Bloody Stealer infiltrate my computer?

It is very common that attackers/cybercriminals use phishing emails to distribute malicious software. In such cases, they send emails containing malicious attachments (or attachments) or website link designed to install malware. Recipients infect their computers with malware after opening a downloaded malicious file. Usually, cybercriminals disguise phishing emails as important, official to trick recipients into opening a malicious Microsoft Office, PDF document, RAR, ZIP or another archive file, executable file (like .exe), JavaScript file. Another popular method to distribute malware is to trick users into installing a certain type of Trojan on their computers. There are Trojans that can infect computers with additional malware (install their payload). Usually, Trojans are disguised as legitimate programs.

Files that users download through unreliable channels are used to distribute malware too. In most cases, cybercriminals use unofficial websites, freeware download websites, free file hosting pages, Peer-to-Peer networks (e.g., torrent clients, eMule), third-party downloaders, and other channels of this kind to trick users into downloading malicious files. Users install malware by opening/executing malicious downloads. A couple of other tools that cybercriminals use to distribute malicious programs are fake software updaters and unofficial activation tools. Fake updaters do not update or fix any software - they install unwanted, malicious software instead, or infect computers by exploiting bugs, flaws of installed outdated software. Unofficial activation tools are also known as 'cracking' tools. These are illegal tools that are supposed to bypass the activation of licensed software. Nevertheless, it is common that these tools are bundled with malware: when users use them, they install malicious software.

How to avoid installation of malware?

It is advisable to avoid opening downloads that come from questionable  websites, Peer-to-Peer networks, third-party downloaders, and so on. Files and applications should be downloaded only from official, legitimate web pages and using direct links. Also, it is recommended not to open attachments or website links in received irrelevant emails. Especially when such emails are sent from suspicious or unknown senders. One more way to avoid installation of malware is to activate the installed operating system and software properly and keep it up to date. It should be done using functions or tools that the official developers provide. Unofficial/third-party tools should never be used neither to update or activate any software. It is common that those tools are bundled with malware. Moreover, it is not legal to use such tools to activate, register licensed software, or use pirated software. Additionally, it is recommended to scan the operating system for viruses regularly, and to it using a reputable antivirus or ant-spyware software. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

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.
