Petya cyber attack that spread around the world was intent on destruction, not on making money

The cyber attack that broke many of the world's biggest companies was intent only on destruction. Experts say that initial suggestions that the software was being used to make money may have been a distraction. The software might instead be part of a plan simply to cripple as many systems, companies and countries as possible, they said. The software itself suggested it was ransomware – when it was loaded up and had taken over users' computers, it asked for money to get the files back. But actually paying that money wasn't possible, and so it generated a tiny amount of cash.
