$1.1B in Crypto Security Losses for First Half of 2026

Crypto security losses reached $1.1 billion across 212 verified incidents during the first half of 2026, according to Blockaid's H1 report published on July 28.

The record-breaking six-month period saw operational security failures cause 74% of stolen funds, rather than exploited smart contract code.

A single DPRK-linked cluster accounted for 55% of losses alone, while Ethereum-related projects lost about $332 million, with code vulnerabilities responsible for much of that total.

The largest Ethereum-linked case was KelpDAO, where attackers released 116,500 rsETH worth roughly $292 million from a bridge contract after falsifying a source-chain message.
