Cross-chain protocol Allbridge halts after $1.65 million flash loan exploit
Allbridge has suspended operations following a flash loan attack that exploited pool ratios, resulting in a loss of approximately $1.65 million. The attacker manipulated pool ratios using a flash loan from Kamino to withdraw assets at favorable rates before bridging funds out.

Allbridge, a prominent cross-chain protocol, has temporarily halted its services after a security breach involving a flash loan exploit. The attacker utilized a $1.12 million flash loan from Kamino to manipulate the pool ratios within Allbridge's liquidity pools. This manipulation allowed the attacker to withdraw assets at advantageous rates before bridging the stolen funds out of the protocol.
The attack resulted in an estimated loss of around $1.65 million. The incident appears to have been driven by vulnerabilities in the pool ratio mechanisms, which the attacker exploited through rapid, large-scale borrowing and asset withdrawal.
Flash loan exploits like this typically occur when protocols do not have sufficient safeguards against rapid, large transactions that can distort pool ratios. The attacker’s ability to manipulate the pool ratios and withdraw assets highlights ongoing security challenges faced by cross-chain bridges.
Allbridge has not yet announced a timeline for resuming operations and is likely investigating the breach to implement stronger security measures. This event underscores the importance of rigorous security audits and safeguards for DeFi protocols, especially those facilitating cross-chain asset transfers.
The incident may impact user confidence in Allbridge and similar protocols, emphasizing the need for enhanced security protocols in the cross-chain ecosystem.
The security breach highlights vulnerabilities in cross-chain protocols, potentially affecting user trust and future security practices in the ecosystem.
