Greek authorities froze cryptocurrency linked to the February 2025 Bybit hack after tracing funds from a suspicious transaction back to wallets used in the roughly $1.5 billion theft, which the excerpt says is widely attributed to North Korea’s Lazarus Group.

The case shows how blockchain analytics, trained investigators, and public-private cooperation can disrupt laundering after major DPRK-linked cryptocurrency thefts. It matters for DPRK-focused tracking because it documents asset recovery and investigative methods against proceeds from a major Lazarus-attributed exchange intrusion.
