TRM Labs reported 207 crypto hacks in the first half of 2026, the highest semiannual tally on record. Even so, total losses fell to $972 million from $2.3 billion a year earlier.
Smart contract flaws drove 125 incidents, but they accounted for a minority of the damage. TRM estimates 76% of losses (about $740 million) stemmed from operational-layer failures, including private key exposure, compromised signing systems, and broken cross-chain bridge validation.
North Korea-linked activity represented 66% of total losses, largely tied to two infrastructure-level intrusions in April: Drift Protocol ($285 million) and KelpDAO ($292 million).
The report argues audits alone are no longer sufficient, pointing instead to controls over how funds can be moved as the sector's largest risk exposure.
