Gravity Bridge was breached this time, and the official response was quick, shutting everything down immediately. But the key management issue wasn't resolved, and the ecosystem's trust will need to be rebuilt.

Mars Finance News: The Cosmos ecosystem cross-chain bridge Gravity Bridge appears to have been attacked due to a suspected signature key leak, resulting in approximately $5.4 million worth of assets stolen. The official has confirmed a security incident and has urgently paused the bridging service to conduct an investigation, while also requesting validators to suspend validation nodes and coordinators. It is reported that its contract keys may have been compromised.
