Cronos Network Halts Operations Due to Exploit on Tectonic Protocol

The Cronos network halted operations after an exploit on the Tectonic protocol affected approximately $75 million in assets. According to onchain researcher Weilin Li, the attacker manipulated the price of TONIC, Tectonic's governance token, which has thin market liquidity. The attacker used artificially inflated TONIC as collateral to borrow other assets from the protocol.

The attack was discovered when it was found that around $6 million of the compromised assets had been bridged to Ethereum before the halt. Cronos validators took an unprecedented step by rolling back the chain state to a point prior to the exploit, taking the entire network offline while security teams assessed the incident.

The network resumed block production after the rollback, with some connected services still recovering from the disruption. Kris Marszalek, CEO of Crypto.com, clarified that the company's app and exchange were not affected by the exploit.
