Dangerous Tools in Clumsy Hands: Lessons from the VanHelsing Ransomware Leak
Veeam, Thursday, August 7th, 2025
For many organizations, this is the nightmare scenario: you think you've negotiated your way out of a ransomware attack, you've paid the ransom demanded, and you've waited for the promised decryption tool. But when you think your data is safe and the ordeal is finished, you discover your data is still lost.
This isn't always because of bad faith or deliberate betrayal. When ransomware developers engage in internal conflicts, they often steal or leak each other's tools. As a consequence, these compromised tools often reach inexperienced criminal affiliates who lack the technical expertise to properly implement them.
This creates an environment where these operators can successfully deploy ransomware attacks and encrypt victims' data, but cannot reliably decrypt it afterward, even if they intend to honor ransom payments. The result is a breakdown: the technical skills needed to launch attacks have become separated from those required to reverse them, leaving both criminals and victims unable to recover encrypted data despite successful extortion attempts.
