Top claims

▪Cosmos Labs initially misjudged the vulnerability as posing no risk to live networks, incorrectly concluding it only affected non-18-decimal networks rather than all Cosmos EVM chains.
▪The attacker on MANTRA moved 600 million tokens from a burn address and 120.9 million tokens from a legacy genesis-era multisig.
▪The Cosmos EVM vulnerability exposed a security gap spanning around 40 blockchains within the broader Cosmos ecosystem.
