US sanctions three N.Korea hacking groups behind major thefts

The US Treasury on Friday placed sanctions on three North Korea government-sponsored hacking operations which it said were behind the theft of possibly hundreds of millions of dollars and destructive cyber-attacks on infrastructure.

The Treasury said the three groups -- dubbed Lazarus Group, Bluenoroff and Andariel -- were behind major thefts from financial institutions and cryptocurrency exchanges, as well as the 2018 WannaCry hack that crippled Britain's National Health Service.
