Cosmos's Gravity Bridge announced it would shut down after being attacked.

CoinFeed reported on May 31 that the Cosmos ecosystem cross-chain bridge Gravity Bridge was previously suspected of being attacked due to a leaked signature key, resulting in the theft of approximately $5.4 million in assets. The official team has confirmed the security incident and has immediately suspended bridging services to conduct an investigation. They have also requested validators to suspend the operation of validator nodes and coordinators.
