Hackers from North Korea are notoriously effective at stealing crypto, with one estimate attributing 60% of all losses last year to DPRK-linked groups. These hackers enlist several different vectors of attack, making it all the more difficult to spot them in the act. Last week, it took just 20 minutes for alleged North Korean hackers to drain $6.3 billion from Binance, in what is the biggest crypto hack on record. The attackers compromised a Binance engineer's work computer through a fake job interview, used an internal AI tool to gain control of other engineers' computers, and then used stolen credentials to hijack an internal wallet signing service, the exchange said.
