BTCamant Ransomware Description

Security researchers have uncovered the BTCamant ransomware which is still under an active investigation. The virus’s name comes from Mission 1996 which is a reference from the “Mision: Impossible” movie. According to the released information so far this is a strain or an improved version of the Radamant ransomware, an old virus that was first uncovered in December 2015.

It encrypts target user files using the AES-256 cipher and demands a ransom payment of 0.5 Bitcoins. It is very likely that the virus targets the same list of file type extension as the core virus. The full list includes the following data:

The crafted ransom note has the following contents:
