North Korean cyberattacks on the crypto industry are getting more sophisticated, warns a Paradigm report. These attacks range from exchange hacks to phishing and supply chain hijacks, sometimes taking a year to unfold. The UN estimates North Korean hackers have netted $3 billion from 2017 to 2023, with a surge in 2024-2025, including $1.7 billion from WazirX and Bybit. At least five groups, including the notorious Lazarus Group, are involved. Lazarus is known for high-profile attacks and predictable laundering tactics, often converting stolen assets to Bitcoin.
