DeFi Lending Exploits Surge: Price Manipulation Hits Record High
Decentralized finance (DeFi) lending is facing a crisis of price manipulation, with 32 exploits recorded so far in 2026, according to blockchain intelligence firm TRM Labs. This marks a significant increase from previous years, with price manipulation now accounting for one in eight crypto hacks.
The issue came into focus on August 30, when an attacker manipulated the price of TONIC, the governance token of the Cronos-based lending protocol Tectonic, and borrowed approximately $75 million from its lending pools. The attacker drove the price of TONIC roughly 100 times higher in about 20 minutes, exploiting a mismatch between reported price and realizable liquidity.
TRM Labs notes that DeFi lending protocols are increasingly vulnerable to price manipulation attacks because they rely on economic inputs, such as collateral valuation, which can be easily manipulated. This is particularly true for low-liquidity assets, which can be temporarily distorted in price at a relatively low cost.
