Fix for WannaCry

Megan Morrone talks to Iain Thomson about a possible fix for those infected with the Wannacry ransomware. Researchers have found a fix to unlock affected computers. The tool called wannakiwi allows you to avoid paying the bitcoin ransom, but only if you’re running Windows XP, Windows 7, and Windows 2003 AND if you haven’t rebooted your PC since the attack. The key is not magic, its math that works by finding all the prime numbers that are stored in the ransomware’s code. A different tool called WannaKey was released yesterday but only worked on Windows XP and required a second app.
