North Korean crypto hackers siphoned off almost $400 million in crypto through cyber attacks in 2021 according to brand-new information from Chainalysis.

The kind of crypto taken has actually likewise seen a transformation according to the Jan. 13 report from the blockchain analytics company. In 2017, BTC represented almost all the crypto taken by the DPRK, however it now represents simply one fifth:

They initially switched ERC-20 coins for Ether (ETH) at decentralized exchanges. Then the ETH was sent out to a mixer and switched for Bitcoin (BTC), which was likewise blended. Finally, BTC was sent out from the mixer to centralized Asian exchanges as a most likely fiat off-ramp.
