More about information stealers

Typically, threat actors use malware like VectorStealer to steal login information (e.g., usernames, email addresses, passwords), credit card details, ID card information, data from various applications (e.g., messengers, crypto-related extensions, gaming apps) and clients, etc.

There are different types of information stealers with different capabilities. For instance, information stealers can function as keyloggers - they record keyboard input. Also, they can be designed to extract data from web browsers (autofill data, passwords, browsing history, etc.).

Depending on the extracted data, cybercriminals can use it to steal online accounts, identities, money (including cryptocurrency), and for other malicious purposes. It is important to mention that stolen email (or other) accounts can be used to trick other users into sending money, downloading malware, and more.

Malware of this type in general

Information stealers are used mostly for monetary gain. Threat actors misuse stolen information by themselves and (or) sell it to third parties on hacker forums or elsewhere. Typically, they target data that can be used to steal money, online accounts, identities, etc. Examples of different information stealers are LummaC2, MintStealer, and Rhadamanthys.

How did VectorStealer infiltrate my computer?

Typically, cybercriminals send emails containing malicious attachments or links or use web pages hosting pirated software (or cracking tools, key generators) to trick users into infecting computers with malware. They also use fake installers, P2P networks, third-party downloaders, fake software updaters, and similar channels to distribute malware.

Users infect computers via malicious MS Office, PDF documents, executables, JavaScript files, ISO files, archives, and other files. In most cases, computers get infected after users download and execute malware by themselves.

How to avoid installation of malware?

Double-check emails containing links or attachments. Especially the ones that are irrelevant and sent from unknown, suspicious addresses. Download files and software from official websites and stores only. Keep your computer (the operating system and installed programs) updated.

Scan the operating system for threats regularly. Use reputable security software for computer 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.

After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

Delete malware in Autoruns

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.

Search for malware and delete 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.
