A bridge exploit targeting the AFX protocol drained approximately $24.15 million in USDC, according to reports circulating across on-chain monitoring channels. The attack hit AFX's cross-chain bridge infrastructure, leaving users exposed to significant losses.
Offchain Labs moved quickly to clarify its own exposure. As the company stated, the incident involved a third-party protocol and did not touch Arbitrum's native bridge infrastructure in any way. The underlying Arbitrum network continued operating normally throughout the event.
Bridge exploits have repeatedly proven to be among the costliest attack vectors in crypto. Cross-chain infrastructure handles large pools of locked assets, and a single vulnerability in the smart contract logic or message verification can let an attacker drain funds in minutes. The AFX incident on Arbitrum fits a pattern that has cost the broader DeFi ecosystem hundreds of millions of dollars over the past two years.
At the time of writing, the full technical breakdown of how the attacker accessed the funds had not been publicly confirmed by AFX. Investigators and on-chain analysts were still tracing the movement of the stolen USDC.
