The apparently random attack, called "WannaCry," hit on Friday and spread like wildfire before a British malware researcher identified as Marcus Hutchins was able to halt it temporarily on Saturday, when workers in many companies weren't in their offices.

The malware spreads as a worm — scanning other computers linked to any machine or system it infects for the same defect and leaping onto them — through a vulnerability in Microsoft systems, particularly on outdated software like Windows XP or Windows Server 2003.

The malware includes an encryption package that automatically downloads itself to infected computers, locking up nearly all of the machines' files and demanding payment of $300 to $600 for a key to unlock them.
