Cosmos Labs revealed a security breach in its Cosmos EVM module, which supports Ethereum-compatible smart contracts across multiple Cosmos-based blockchains. The flaw led to attacks on several networks, including MANTRA, KiiChain, and TAC, causing unauthorized token transfers and forcing some chains to pause operations. This incident highlights risks of shared blockchain infrastructure where a single vulnerability can impact many projects. Cosmos Labs is investigating and coordinating with affected chains to contain the issue and plan safe restarts, emphasizing the need for ongoing security vigilance in modular blockchain systems.
In August 2026, Cosmos Labs issued an emergency halt for all Cosmos EVM-based blockchains following a major security breach. KiiChain lost over 148 million KII tokens through 18 attacks exploiting vulnerabilities in vesting and staking mechanisms. TA...
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 ope...
