The newly observed “LockFile” ransomware has skilfully infiltrated multiple sectors by exploiting the “PetitPotam” vulnerability in Microsoft Windows systems. In complex and technically sophisticated supply-chain attacks, cyber-threat actors gained access to targets’ Microsoft Exchange Servers, making use of a publicly available PetitPotam proof of concept (PoC) to access domain controllers and deploy LockFile. The multiple, domino-like layers of the attacks signify the increasingly advanced capabilities of ransomware and ransomware operators alike. They have raised a red flag for defenders, who should strive to be as agile and resourceful as attackers―as well as one step ahead, when it comes to preventing vulnerability exploitation.
