Security flaw in Cosmos EVM leads to multiple token drains and network halts across chains

Cosmos Labs identified a security incident affecting multiple Cosmos EVM chains, urging validators to halt networks to prevent further losses. Attacks on KiiChain and TAC resulted in significant token drains, while MANTRA paused and later resumed operations without user fund losses. Cosmos Labs has yet to disclose the full scope, vulnerability details, or total losses but plans a detailed incident report. The incident highlights risks in shared blockchain software and the need for coordinated security responses.
