Global hack appears aimed at damage, not money

The "ransomware" attack that struck Ukraine and has since spread to about 65 countries might not be a regular ransomware attack after all. Instead, its code indicates it is more like a "wiper," according to Matt Suiche, founder of cybersecurity startup Comae Technologies.

What it means: "The goal of a wiper is to destroy and damage. The goal of a ransomware is to make money," Suiche writes. Instead of just encrypting files when it infects a device, this hack encrypts your entire hard drive and the Master Boot Record so that it is totally inoperative, according to Radware. This also causes the whole computer to restart.
