Malicious programs are typically presented as or bundled with ordinary software or media. Ransomware and other malware are mainly proliferated using phishing and social engineering tactics. However, these prograns have two key differences in-between - the cryptographic algorithms they use ( symmetric or asymmetric) and the ransom size. Ransomware-type programs operate by encrypting data and demanding ransoms for the decryption.
Youfileslock, WANNAFRIENDME 2, Hhwq, Police_Decrypt0r, and ELITEBOT are merely some examples of the ransomware that we have analyzed. We highly recommend keeping backups in several different locations (e.g., remote servers, unplugged storage devices, etc.) - to avoid permanent data loss. The only solution is recovering them from a backup (if one is available). Unfortunately, removal will not restore already compromised files. To prevent U2K ransomware from further encryptions - it must be eliminated from the operating system. Therefore, we strongly advise against paying and thus supporting this illegal activity. To initiate the recovery process, the note instructs victims to contact the attackers.īased on our extensive experience researching ransomware infections, we can conclude that decryption is usually impossible without the cyber criminals' interference.įurthermore, despite meeting the ransom demands - victims often do not receive the promised decryption tools. According to the message, purchasing the decryption tool is the sole method of recovering the affected data. The ransom note informs victims that their files have been encrypted. Screenshot of files encrypted by U2K ransomware: Once this process was completed, a ransom-demanding message - " ReadMe.txt" - was created. U2K" extension, e.g., a file initially titled " 1.jpg" appeared as " 1.jpg.U2K", " 2.png" as " 2.png.U2K", etc. We determined that this malicious program is identical to MME ransomware.Īfter we launched a sample of U2K on our test machine, it encrypted files and altered their names. While inspecting new submissions to VirusTotal, our researchers discovered the U2K ransomware.
