PeckShield and CertiK reported that Allbridge Core, a cross-chain bridge, was exploited for roughly $1.65 million through a flash loan. The team paused the protocol and urged users to withdraw liquidity from affected pools.
Why it matters
Cross-chain bridges remain high-value targets because they connect liquidity across multiple blockchain networks. A flash loan can give an attacker temporary access to substantial capital, increasing the speed and scale of an exploit without requiring the attacker to hold those funds beforehand.
The incident adds another security concern for DeFi users providing liquidity to bridge-related pools. The pause limits protocol activity while the affected pools and the exploit are assessed.
Market impact
Users with liquidity in affected pools face an immediate withdrawal decision, while broader DeFi markets will watch for details on the attack path, losses and any recovery plan. The $1.65 million figure makes this a contained exploit in dollar terms, but the event reinforces the risks of bridge infrastructure and flash-loan-enabled attacks.
