A cross-chain bridge security incident has once again impacted stablecoin infrastructure. After Allbridge Core was exploited by hackers, approximately $1.66 million in crypto assets were withdrawn, affecting multiple on-chain liquidity pools. Following the incident, the protocol suspended the related bridge services and began collaborating with security firms to track the movement of funds.
Involves two blockchains
Public information indicates that the affected component is the cross-chain stablecoin bridge of Allbridge Core. The stolen funds primarily came from liquidity pools on BNB Chain and Avalanche, with the attacker withdrawing assets by manipulating exchange rates.
Allbridge Core is a cross-chain transfer product within the Allbridge ecosystem, primarily used for transferring stablecoins between different blockchains. This incident highlights that vulnerabilities in cross-chain bridges regarding liquidity management and pricing mechanisms can still be rapidly exploited.
The protocol has suspended service.
After the incident was disclosed, the project team stated that it has suspended Allbridge Core's bridging services to prevent further losses. The team is currently communicating with blockchain security firms and relevant partners to identify the attack vector and track the transferred assets.
Based on past cases, post-attack responses to cross-chain bridges typically include pausing the protocol, on-chain labeling of attack addresses, contacting exchanges, and assessing the potential for fund recovery. The key focus of follow-up actions in this incident will be the security of remaining funds and the recovery plan for affected pools.
Cross-chain bridge risks are once again under scrutiny.
Cross-chain bridges have long been one of the most vulnerable areas in the cryptocurrency industry, as they connect multiple blockchains and often feature more complex contract structures and liquidity designs. Once there is a vulnerability in pricing, validation, or message transmission, attackers can rapidly amplify their gains.
For Allbridge Core, this attack not only resulted in direct financial losses but may also undermine user confidence in cross-chain stablecoin bridges. The market will now be watching to see whether the project team releases a more comprehensive technical post-mortem and outlines a plan for affected users.
