North Korea’s hackers have been linked with many attacks, including the 2014 Sony hack, but it looks like the totalitarian state is now targeting bitcoin, and crypto coin exchanges in particular, with its hacking teams.

That’s according to a new report from cybersecurity firm FireEye, which claims to have tracked at least five attacks on bitcoin exchanges, or individual bitcoin wallets, within the past six months. The targets reportedly include South Korea-based exchange Yapizon, and two others that were not named.
