BullWall Ransomware Containment does not entirely inspect a file to determine if it is ransomware. An authenticated attacker could bypass detection by encrypting a file and leaving the first four bytes unaltered. Versions 4.6.0.0, 4.6.0.6, 4.6.0.7, and 4.6.1.4 were confirmed to be affected; other versions before and after may also be affected.
