North Korean hackers have learned to launder stolen cryptocurrency through their own shitcoins—for a test, they created 6 meme tokens and moved money between their own wallets, passing off the stolen funds as trading profits.

In this way, the attackers attempted to legalize about $430,000.

Analysts warn that the scheme is cheap and allows for laundering much larger amounts—with sufficient resources, hackers can set up an entire pipeline of fake tokens and transactions.
