Written by Tomas Meskauskas on
What kind of malware is Kral?
Kral is an information-stealing malware delivered via a downloader with the same name and other similarities. It is known that Kral stealer targets cryptocurrency wallets and browser data. Systems that may be infected with this malware should be scanned using a reputable security tool as soon as possible.
More about Kral
One of the functions of the Kral is to steal information from cryptocurrency wallets. These wallets can hold private keys, passwords, and other data necessary for accessing and managing cryptocurrency. By compromising these wallets, Kral allows cybercriminals to gain unauthorized access to the victim's funds and steal them.
The second functionality involves harvesting browser data. This can include login credentials, saved passwords, autofill information (e.g., names, addresses, credit card details), cookies, and browsing history. This information can be used to steal identities, online accounts, make fraudulent purchases, spread scams, deliver malware, and more.
Additionally, Kral creates a folder in the "C:\ProgramData\ directory", where it stores not only the stolen data but also system information (local time, time zone, and CPU details). After collecting the targeted information, Kral compresses the folder's contents into a ZIP file and sends it to a command-and-control (C2) server.
Notably, Kral only collects data once per session. However, if the victim inadvertently launches the malware again, it will repeat the data theft process, which may involve accessing more personal information than previously.

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.
