Summary

In April 2026, North Korea-linked threat actors attributed to the Lazarus Group and its subunits executed two separate, high-value cryptocurrency exploits within 18 days — draining approximately $285 million from Drift Protocol on April 1 and approximately $292 million from KelpDAO on April 18. Combined, the two attacks account for an estimated $577–635 million in losses, comprising 76% of all documented cryptocurrency hack value through April 2026 and representing the largest coordinated DPRK crypto theft campaign on record.
