The NotPetya ransom screen, 27 June 2017

JUN 28 2017

The message shown to machines hit by NotPetya on 27 June 2017. It demanded a ransom but had no working decryption path: it was a destructive wiper disguised as ransomware, seeded through a Ukrainian tax-software update and spread worldwide. Maersk, Merck and FedEx's TNT each lost hundreds of millions; total damage is estimated at around ten billion dollars.
