Echo Protocol Reports Security Breach on Monad Deployment, $816,000 Affected

According to Huoxing Finance, on May 19, Echo Protocol announced that unauthorized activity occurred on its eBTC deployment on Monad, resulting in abnormal minting and asset losses. Preliminary investigations indicate the issue stemmed from compromised administrative keys related to the Monad deployment, with approximately $816,000 in assets confirmed affected. Echo stated that the Monad network itself was unaffected and continues to operate normally. The team has regained control of the administrative keys and burned the remaining 955 eBTC held by the attacker. The project further clarified: - The incident appears limited to the Monad deployment; - No evidence suggests any impact on Aptos; - aBTC on Aptos and eBTC on Monad are independent, non-interoperable assets; - The current risk exposure on Aptos is approximately $71,000. As an additional security measure, Echo has suspended cross-chain functionality for the Monad deployment and is upgrading the relevant EVM bridge contracts and permission control mechanisms.
