Cosmos Security Incident Triggers Urgent Pause of Validator Activity

A security incident has hit the Cosmos ecosystem after Cosmos Labs flagged an active issue in its EVM module, prompting an urgent call for connected chains to pause validator activity. The affected network's native token has seen a significant drop in trading activity.

The incident emerged on August 25th, 2026, and has left the market uncertain about how far-reaching the problem is. Cosmos Labs has not disclosed specific vulnerabilities or named which EVM chains are affected by the issue.
