Possible damage

Depending on the type of the data extracted using MintStealer, it could be used for different malicious purposes. For instance, cybercriminals could use obtained information to steal identities, money, online accounts, make fraudulent purchases, etc. It is also common that threat actors sell stolen data to third parties.

More examples of information-stealing malware are Rhadamanthys, Demon, and StealDeal.

How did MintStealer infiltrate my computer?

Cybercriminals use various methods to trick users into infecting computers. They often send emails containing malicious attachments or links or use websites hosting cracked/pirated software (or cracking tools, key generators). They succeed when users execute malware by themselves.

Trojans, fake software updating tools, P2P networks, third-party downloaders, free file hosting pages, etc., are also used as channels for malware distribution. Most threat actors use malicious MS Office, PDF documents, JavaScript files, executables, ISO files, archives, and other files to trick users into infecting their computers.

How to avoid installation of malware?

Do not download files and programs from unreliable sources (e.g., shady pages, P2P networks, third-party downloaders). Download them from official websites and stores only. Double-check irrelevant emails received from suspicious, unknown addresses. Especially when they contain links or files. Such emails tend to be used to deliver malware.

Keep your computer and installed programs updated. Use a reputed antivirus solution for computer protection and run system scans with it regularly. 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.

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.

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.
