Between August 20 and August 25, 2026, attackers exploited a critical vulnerability in Cosmos EVM, draining approximately $5.7 million from six blockchain networks. Cosmos Labs had received a report about this flaw in April but misclassified it as low risk, leading to a delayed patch. The exploit involved an integer underflow, allowing attackers to manipulate balances and steal funds from large holdings.
