Bybit: Unauthorized activity was detected in an ETH cold wallet, the customer's funds were safe and the operation would not be interrupted.

PANews reported on February 21 that Bybit posted on X platform that it detected an unauthorized activity involving an ETH cold wallet. When the incident occurred, the ETH multi-signature cold wallet was transferring money to the hot wallet. Unfortunately, the transaction was Complex attack manipulation, which masks the signature interface and changes the underlying smart contract logic. As a result, an attacker can control the affected ETH cold wallet and transfer its assets to an unknown address.

The Bybit security team is actively investigating the incident with blockchain forensic experts and partners, and any team with expertise in blockchain analytics and fund recovery and who can assist in tracking these assets is welcome to collaborate. Bybit said that all other Bybit cold wallets are absolutely secure, all customer funds are safe, operations are going on as usual, without interruption, and updates will be provided as soon as possible.
