South Korean cryptocurrency exchange Upbit says hackers stole $49 million worth of ethereum from its hot wallet. $158 million has been stolen via seven major cryptocurrency heists so far this year. North Korea is one of the main culprits, experts say. Experts say Pyongyang-based regime run by Kim Jong-un is ready cash to cash in and launder the stolen funds. The heist shows that cryptocurrency exchanges continue to sport a massive hacker bullseye, for obvious reasons, but there is still plenty for the potential taking.”]
