The most common malware distribution methods include: malicious attachments/links in spam emails and messages, untrustworthy download sources (e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, etc.), drive-by (stealthy and deceptive) downloads, illegal software activation tools ('cracks'), fake updates, and online scams. Once such a file is opened - the infection process is jumpstarted.

Infectious files can be in various formats, e.g., archives, executables, PDF and Microsoft Office documents, JavaScript, etc. Malicious programs are typically presented as or bundled with ordinary content. Malware (ransomware included) is proliferated using phishing and social engineering tactics. The malware operates practically identically throughout, but these programs do have two significant differences in-between - the cryptographic algorithms they use ( symmetric or asymmetric) and the ransom size. Nuhb, Stopfiles, and OnlyFans are just a few examples of the ransomware we have analyzed. We highly recommend keeping backups in multiple different locations (e.g., remote servers, unplugged storage devices, etc.) - to avoid permanent data loss. The sole solution is recovering them from a backup, if one was created beforehand and is stored elsewhere. However, removal will not restore already affected files. To prevent Ygvb ransomware from further encryptions, it must be eliminated from the operating system. Therefore, we strongly advise against meeting the ransom demands and thus supporting this illegal activity. Additionally, the message mentions that decryption can be tested by sending the attackers a single encrypted file.īased on our extensive experience analyzing and researching ransomware, we can conclude that decryption is usually impossible without the cyber criminals' interference.įurthermore, despite paying - victims often do not receive the promised decryption tools. The price of the recovery tools is stated to be 980 USD, and if victims establish contact with the cyber criminals within 72 hours - the ransom will be halved (490 USD). The only way to restore them is to purchase the decryption keys and software from the attackers. The ransom note informs victims that their files have been encrypted. Screenshot of files encrypted by Ygvb ransomware: Once this process was completed, a ransom-demanding message - ' _readme.txt' - was created. For example, a file initially titled ' 1.jpg' appeared as ' 1.jpg.ygvb', ' 2.png' as ' 2.png.ygvb', etc. Our researchers found this program while inspecting new submissions to VirusTotal, and determined that it belongs to the Djvu ransomware family.Īfter being launched onto our test machine, Ygvb encrypted files and appended their filenames with a '. Ygvb is a piece of malicious software classified as ransomware.
