Echo Protocol has successfully regained control of its management key and destroyed 955 eBTC that were previously held by an attacker. The announcement was made on May 19 via the protocol's official social media channels. The current exposure on the Aptos chain is approximately $71,000, affecting the Echo lending market and Hyperion liquidity pools, though no fund losses have been reported. As a precaution, Echo Protocol has suspended operations of the Aptos bridge while a security review is conducted. Although Echo Aptos Lending remains unaffected, it has been paused to ensure security. The team continues to monitor the situation closely to prevent further incidents.
