Nervos Network Hack

REPORTED LOSS $3.7M
Medium Access Control

What happened

On June 2, 2025, the Nervos Network's ForceBridge was exploited, leading to the theft of approximately $3.7 million in assets—$3.1M on Ethereum and $0.6M on BNB Chain. A malicious actor gained control over the bridge and drained funds including USDT, USDC, ETH, DAI, and WBTC, all of which were subsequently swapped to ETH and funneled through Tornado Cash. In response, the Nervos team paused all bridge contracts and is actively investigating the incident with the help of law enforcement and partner exchanges.

The attacker appears to have compromised the ForceBridge contract, gaining unauthorized control and initiating a series of suspicious withdrawals. The stolen funds included:

257,800 USDT

539.09 ETH

898,300 USDC

60,400 DAI

0.79 WBTC

All assets were swapped to ETH using decentralized exchanges and then laundered through Tornado Cash to obscure their trail. The exploit occurred across multiple chains, primarily Ethereum and BNB Chain. Following detection by Cyvers and other monitoring tools, Nervos paused ForceBridge and acknowledged “abnormal activity,” initiating an internal and external investigation. The protocol’s security flaws—likely in access control or message verification within the bridge—remain under review.
