Cosmos EVM security breach prompts validator halts across multiple chains
An active security incident has impacted the Cosmos EVM module, leading Cosmos Labs to advise validators across multiple chains to halt operations. Affected networks include KiiChain, TAC, and MANTRA, with KiiChain reporting a significant loss of over 148 million KII tokens. The vulnerability appears linked to the ICS20 precompile, a component of the Cosmos IBC framework. Cosmos Labs is actively investigating the issue and plans to release a detailed incident report once the situation is resolved.
Key points
- KiiChain reports significant loss: Over 148 million KII tokens drained across 18 attacks before validators halted the network.
- TAC halts network after exploit: One account drained via a Cosmos EVM precompile exploit; validators halted the network at block 24,671.
- MANTRA resumes after 30-hour halt: Network paused due to security incident; resumed block production after deploying an updated release.
- Cosmos Labs issues advisory: Urges validators across affected chains to suspend operations while investigating the security incident.
