STAFS Virus (.STAFS File) – Detailed Description
We just received reports about a ransomware that appends the .STAFS file extension to encrypted files.
The STAFS virus is a dangerous new malware threat which is being spread by an unknown hacker or criminal group, most likely as part of the ransomware-as-a-service model. Our analysis indicates that this is in fact a new iteration of the Dharma ransomware.
In other words, Dharma ransomware is back once again. The current version of the Dharma family ransomware encrypts files by appending the .STAFS extension to them, making them inaccessible. It also may add a unique identification number as previous versions did. All encrypted files will receive the new extension as a secondary one. The ransomware drops a ransom note, which gives instructions to victims on how they can allegedly recover their files.
STAFS virus might spread its infection via a payload dropper, which initiates the malicious script for this ransomware. The ransomware can be distributed in malspam campaigns, or in freeware packages and malicious torrents. Freeware which is found on the Web can be presented as helpful and can also be hiding the malicious script for the cryptovirus. Read the tips for ransomware prevention from our forum.
Long story short, STAFS virus is a ransomware that encrypts your files and shows a ransomware note. This is how the ransom note looks:
We usually advise against paying any ransom sum as this further enables cybercriminals to initiate new ransomware campaigns. There is also no guarantee that a decryption key will be sent to you, as, after all, you’re dealing with criminals.
Also note that this ransomware could make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows system. All encrypted files will receive the STAFS extension alongside a unique identifier number. That extension will be placed as a secondary one to each file. Audio, video, image files as well as documents, backups and banking data can be encrypted by the ransomware.
The STAFS could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:
→vssadmin.exe delete shadows /all /Quiet
