Just over a month ago we reached out to you to educate you about the WannaCry ransomware that impacted more than 150 countries. Today we have another global cyberattack taking place. A new strain of ransomware is spreading rapidly. Called Petya, or Petwrap, ransomware, it has hit companies everywhere across Europe today, including Ukraine's government facilities, electric grids, banks, and public transportation, demanding a $300 ransom in Bitcoin in the process. It has since spread to companies around the world.
So how does this Petya attack work, exactly? Going after Windows servers, PCs, and laptops, this cyber attack appears to be an "updated variant" of the Petya
malware virus. It uses the SMB (Server Message Block) vulnerability that WannaCry did, however in the case of Petya it encrypts, among other files, your master boot file. These messages recommend you
conduct a system reboot, after which the system is inaccessible. This basically means the operating system won't be able to locate files.
