North Korean hackers launched at least seven attacks on cryptocurrency platforms last year to steal nearly $ 400 million in digital assets, according to a report from blockchain analytics firm Chainalysis.

The attacks mainly targeted investment firms and centralized exchanges.

“Once North Korea obtained custody of the funds, it began a thorough laundering process to cover and collect,” the report said.
