Onchain Lens said in a post on X that 224 publicly disclosed crypto hacking incidents were recorded in the first half of 2026, with total losses reaching about $1.32 billion. The largest losses came from access control failures, phishing attacks and oracle-related issues. Within the access control category, compromised permissions and privileged access were tied to several of the biggest incidents, including Kelp DAO with losses of $292 million and Drift Protocol with $280 million. Other named cases in that group included Humanity Protocol, Step Finance, Truebit, Resolv Labs, AFX and BonkDAO. Onchain Lens also said social engineering attacks caused $282 million in losses. For oracle-related incidents, the post listed Ostium, Blend Protocol and Bonzo. The data points to a familiar pattern in crypto security: a small number of incidents accounted for a large share of total losses, with compromised permissions and privileged access standing out among the costliest attack vectors disclosed during the period.
