How to save your files
Jason Reaves at SentinelOne explains how ThiefQuest gets a hold of your files, how they were able to reverse it, and how victims can get their hands on the decryption device. For those affected, ThiefQuest expects users to cough up $50 within 72 hours, or else the program will swiftly delete any files it has taken hold of. In general, “the malware exhibits multiple behaviors, including file encryption, data exfiltration and keylogging,” Reaves wrote in the SentinelOne report. The security report claims ThiefQuest isn’t as complex or scary as it might have seemed because the decryption tool was never removed from the attacker’s program. This meant that reversing the damage wasn’t particularly challenging. For those who have become victims to ThiefQuest, feel free to download SentinelOne’s free decryption tool. This is intended to free your files from ransom and protect against the malware’s simplistic coding tool.
