Crypto Hacks Hit Record $1.1B in H1 2026

A comprehensive H1 2026 report shows $1.1B lost across 212 incidents, the highest half-year on record. Compromised keys now cause 74% of losses, not code bugs. New attack methods like EIP-7702 and AI prompt injection are emerging. Ethereum and Solana were hardest hit, with KelpDAO's $292M exploit the single biggest. A fresh incident: unexplained 594 BTC sweep from Coldcard Mk3 wallets, possibly a coordinated attack, plus a Bitcoin extortion scam warning.
