A malware infection that targeted Windows computers in Ukraine. Introduced in 2017, and alleged to be from Russia, NotPetya malware spread across Europe causing billions of dollars' worth of damage. Merck, FedEx, Maersk and other companies each lost hundreds of millions of dollars. Unlike its Petya namesake (see
Petya), NotPetya encrypts everything on the hard drive, and it spreads on its own accord rather than in an email attachment. A Windows patch for the NSA-exploited SMB flaw known as EternalBlue avoided the NotPetya infection. See
