Price-manipulation exploits in decentralized finance (DeFi) reached 32 through August 2026, according to TRM Labs, far exceeding the previous annual record of 12 set in 2025. Such attacks now account for roughly one in eight crypto hacks, compared with one in 17 in 2022. Most use a flash loan (uncollateralized loan repaid within one transaction) to inflate a thinly traded token, use it as collateral to borrow more valuable assets, and profit before the price normalizes. TRM Labs linked the increase to the spread of protocols that depend on low-liquidity oracles (blockchain price feeds). The median loss was approximately $219,000 per hack in the first half of 2026, while 207 hacking incidents caused $972 million in aggregate losses. Two August exploits illustrated different outcomes: a Cronos chain rollback limited losses from the Tectonic attack, while Moonwell users received no such intervention. Lending-protocol total value locked is approaching $50 billion, with active loans nearing $29 billion across more than 570 protocols. Time-weighted average prices, multiple oracle sources, and liquidity circuit breakers have provided greater protection, while European regulators under MiCA and U.S. agencies have signaled greater attention to DeFi security standards.
