Allbridge Core Cross-Chain Bridge Exploited, $1.66M Drained

CoinDesk reports that a fresh cross-chain bridge exploit has again exposed the fragility of stablecoin infrastructure. Hackers targeted Allbridge Core and withdrew about $1.66 million in crypto assets, impacting multiple on-chain liquidity pools. Public information suggests the breach involved Allbridge Core's cross-chain stablecoin bridge. The attacker primarily drained liquidity pools on BNB Chain and Avalanche, extracting funds by manipulating exchange rates. Allbridge Core is a cross-chain transfer product within the Allbridge ecosystem, largely used to move stablecoins between different blockchains. The incident underscores how weaknesses in liquidity management and pricing mechanisms can be exploited quickly. Following disclosure, the team said it has suspended Allbridge Core bridging services to prevent additional losses. The protocol is working with blockchain security firms and partners to identify the attack vector and trace the stolen funds. In past cross-chain bridge incidents, standard response steps have included pausing the protocol, labeling attacker addresses on-chain, contacting exchanges, and evaluating the likelihood of recovery. Key priorities now include safeguarding remaining funds and outlining a recovery plan for affected pools. Cross-chain bridges remain one of crypto's most frequent targets because they connect multiple networks and often rely on complex contract structures and liquidity designs. Flaws in pricing, validation, or message transmission can allow attackers to scale gains rapidly. For Allbridge Core, the loss is not only financial but may also weigh on user confidence in cross-chain stablecoin bridges. Markets are now watching for a detailed technical postmortem and guidance for affected users.
