How to remove Flesh stealer from compromised computers
Written by Tomas Meskauskas on (updated)
What kind of malware is Flesh?
Flesh is information-stealing malware targeting Windows users. It is capable of extracting sensitive data from web browsers and Discord. Once it has collected the stolen data, it is sent to a remote server controlled by the attacker for malicious use. If a computer is infected with Flesh stealer, a system scan using a reputable security tool should be run as soon as possible.
Flesh stealer overview
Flesh stealer is specifically designed to target and steal sensitive information from browsers based on Chromium and Mozilla platforms. It can pilfer data from around 70 browser-based cryptocurrency extensions. With this information, threat actors can transfer the stolen funds to their wallets, resulting in financial loss for the victims.
Also, Flesh can extract data from two-factor authentication (2FA) extensions. If cybercriminals acquire the 2FA codes, they can bypass this protection and gain unauthorized access to sensitive accounts, including email, financial services, and other platforms. Additionally, Flesh is capable of harvesting Discord tokens.
These tokens can provide unauthorized access to users' private communications and personal data on the Discord platform. Lastly, Flesh can restore Google cookies deleted by users. This feature can be exploited to monitor activities and steal more information.
The threat actors behind FleshStealer offer subscription plans for potential buyers. It is known that there is a discount on the subscription options: a one-month plan is available at a 20% discount, a three-month plan at a 30% discount, and a lifetime plan, also at a 30% discount.

How did Flesh infiltrate my computer?
Typically, threat actors deliver malware by sending emails containing malicious files or links, hiding malware in pirated software, exploiting vulnerabilities in outdated software or operating system, and creating technical support scams. In most cases, their goal is to trick users into downloading and running malware on computers.
Other distribution channels include P2P networks, compromised or fake websites, third-party downloaders, infected removable (e.g., USB) drives, malicious advertisements, and fake or hijacked social media profiles.
How to avoid installation of malware?
Only download programs and files from trusted sources, such as official web pages and reputable app stores. Do not download pirated software or use cracking tools and unofficial key generators. Exercise caution with attachments and links in unexpected emails from unknown senders. Avoid interacting with ads, pop-ups, or buttons on suspicious websites.
Additionally, keep your operating system, software, and antivirus programs up to date to ensure maximum protection. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check 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".
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.
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 Combo Cleaner Antivirus for Windows.
