NotPetya

A 2017 destructive wiper disguised as ransomware that spread from a compromised Ukrainian accounting software update.

Definition

NotPetya was delivered through the M.E.Doc update mechanism and spread laterally using EternalBlue and credential theft with Mimikatz-like techniques. Although it displayed a ransom note, its encryption made recovery impossible. It caused an estimated 10 billion US dollars in global damage and was attributed to Russia's GRU.

Example

Maersk had to rebuild thousands of servers after NotPetya spread through its network.

Exam tip

NotPetya combines supply chain, worm and wiper concepts; it is a wiper, not genuine ransomware.
