Experts are piecing together the many updates and findings about this malware to figure out what happened. Malwarebytes: “It’s really, really hard right now to identify motivation” The malware overwrites the Master Boot Record and encrypts individual files. It requests $300 in Bitcoin to decrypt the system but despite an estimated $3,000 in payments, there has been no record of victims successfully decrypting their files. The first entities to get infected were critical infrastructure networks like airports, gas and utility companies, public transportation, and banks.”]
