Cosmos Labs urged affected Cosmos EVM chains to request validator halts on Aug. 25 as its security and engineering teams responded to an incident that had already reached multiple networks, crypto.news reported. Cosmos EVM is a software module that lets Cosmos SDK chains execute Ethereum-compatible smart contracts, so a vulnerability in a common component can expose independent networks running affected versions. Cosmos Labs did not identify the underlying vulnerability, the affected chains or total losses in its initial statement, and said it would publish an incident report after the situation was resolved. It did not publish a software version, mitigation instructions or a restart schedule, likely to avoid revealing exploitable details before chains are protected, and directed other teams with questions to its security email.
