Some of the big companies hit by the NotPetya malware in late June have reported losing hundreds of millions of dollars due to the cyberattack.
The NotPetya malware outbreak affected tens of thousands of systems in more than 65 countries, including ones belonging to major organizations such as Rosneft, AP Moller-Maersk, Merck, FedEx, Mondelez International, Nuance Communications, Reckitt Benckiser and Saint-Gobain. Many of the victims were located in Ukraine, the home of a tax software firm whose product was used as the main attack vector.
Researchers initially believed NotPetya (aka PetrWrap, exPetr, GoldenEye and Diskcoder.C) was a piece of ransomware, similar to WannaCry. However, a closer analysis revealed that it was actually a wiper and it was unlikely that victims could recover their files, even if they paid the ransom.
