On-chain analyst Specter reported that the cross-chain bridge Gravity Bridge is suspected to have suffered a hacking attack. Specter explained that the bridge's contract keys may have been leaked, leading to an estimated $5.4 million worth of cryptocurrency being drained. The leaked assets were tallied as approximately $4.3 million in USDC, 274 WETH (approximately $553,000), $434,000 in USDT, and $64,000 in PAYG, among others. Currently, the project team has not released an official statement, and further investigation is needed to determine the exact scale of the damage and the cause of the attack.
