North Korean hackers stole $7.61 billion in crypto in 2026, BitOK finds

BitOK reports that North Korean hackers stole $7.61 billion in crypto during 2026, with major attacks targeting signers rather than exploiting code vulnerabilities. Roughly $4.75 billion of the stolen funds escaped freezes. The scale of the losses and the high share of unrecovered funds highlight persistent custody and key-management risk that traders should weigh when assessing exchange and protocol security.
