Blockchain security firm CertiK reported that crypto losses reached approximately $215 million in August 2026, with DeFi exploits accounting for $144.6 million. Major incidents included a $75 million price manipulation attack on Tectonic protocol that halted the Cronos Network and a $9.3 million exploit of More Markets on Flow EVM.
The Cronos blockchain halted block production on Sunday after an attacker exploited Tectonic, its largest lending protocol, by artificially inflating the TONIC token price roughly 100-fold and using it as collateral to borrow approximately $75 million in assets. Validators paused the network, stranding most of the stolen funds.
DeFi lending protocol Moonwell suffered an $8.7 million exploit after an attacker manipulated the price of MAMO token to borrow real assets against inflated collateral, prompting the protocol to set borrow caps to 1 wei across Base markets.
