Detailed Review: Consecutive Cosmos EVM Vulnerabilities Lead to Losses Exceeding $17M
During the period of August 20 through August 23, malicious actors took advantage of a specific group of flaws found within the vesting accounts and the staking precompile of the cosmos/evm framework. In just three days, these vulnerabilities were used to successfully compromise three different networks: TAC, KiiChain, and MANTRA. The overall nominal losses from these targeted attacks surpassed $17M.
It is very important to clarify that this recent wave of exploits is completely unrelated to the ASA-2026-002 vulnerability from January 2026. That previous situation resulted in roughly $7M in losses for Saga EVM and was caused by an ICS20 nested execution issue. Because of poor analysis, certain media sources have incorrectly blended these two stories together. In reality, the two events involve completely different methods of exploitation, software patches, and code paths.
Please read through the following thread for a complete and comprehensive breakdown of the situation.
