ExPetr ransomware outbreak
While focusing on the destructive consequences of ExPetr (aka NotPetya), few people recall how it began. That’s a shame: One of its distribution vectors practically defines “supply-chain attack.” Attackers compromised the automatic update system of accounting software called M.E.Doc, forcing it to deliver the ransomware to all customers. As a result, ExPetr caused millions in losses, infecting both large companies and small businesses.

At some point, attackers compromised the program developer’s compilation environment, equipping several versions with a backdoor.
