Cronos says the attacker borrowed $120.4 million
According to Cronos’ post-mortem, an attacker manipulated collateral on the Tectonic lending protocol and borrowed $120.4 million across nine markets before validators halted the network on August 30.
Cronos had initially halted block production after the Tectonic exploit, when the scale of the incident was still based on early on-chain estimates. The post-mortem now separates the value borrowed, the value reversed on Cronos and the amount that left the network before the halt.
