Gravity Bridge Suffers $5.4 Million Loss Due to Key Compromise
- Gravity Bridge, a Cosmos-native protocol, was hacked for approximately $5.4 million.
- The attack involved a signing key compromise, allowing unauthorized access to funds.
- Stolen assets included $4.3 million in USDC, wrapped Ether worth about $553,000, and $434,000 in USDT.
- Security firm PeckShield reported the hacker laundered some funds through ChangeNOW and Binance, retaining over 2,100 Ether (around $4.23 million).
- The Gravity Bridge team halted operations for investigation following the incident.
This attack highlights vulnerabilities in cross-chain protocols like Gravity Bridge that rely on validator signatures for asset transfers between networks such as Ethereum and Cosmos. The breach is part of a broader trend of crypto bridge attacks focusing on access control weaknesses rather than smart contract flaws.
In the context of increasing DeFi exploits in recent months, the Gravity Bridge incident underscores ongoing security challenges within the sector as attackers continue targeting cross-chain protocols with compromised keys being a common method of attack.
