Petya Ransomware Uses DOS-Level Lock Screen, Prevents OS Boot Up (softpedia.com)

An anonymous reader writes: A new type of ransomware was discovered that crashes your PC into a BSOD, restarts your computer, and then prevents your OS from starting by altering the hard drive's master boot record (MBR). This keeps the user locked in a DOS screen that doubles as the ransomware's ransom note. The ransomware's name is Petya, and was currently seen only targeting HR departments in Germany.

This won't impact a Mac, nor will it impact Linux (it's an .exe file). The TFA referred to Windows, so should the summary.

Just like as usual - most rampant exploits and malware are Windows-only.
