According to Cyvers, a blockchain security firm monitoring the incident, an unknown address gained unauthorized control over the bridge. The attacker drained about 257,800 USDT, 539 ETH, 898,300 USDC, 60,400 DAI, and 0.79 WBTC. These assets were then converted to ETH and sent through Tornado Cash, a privacy-focused protocol to obscure transaction history.

Nervos Halts Contracts

In response to the exploit, the Nervos team paused all affected contracts and launched an investigation. While details on the exact exploit remain limited, the breach stems from compromised access control, allowing the attacker to seize bridge authority.

“We’ve detected abnormal activity on #ForceBridge and have paused the service as a precaution. Our team is investigating. Updates will be shared ASAP. Thank you for your patience,” the team stated.

Rising Wave of Exploits Fuels Community Concerns

The recent Nervos exploit has sparked concern across the online community. One user on X replied to Cyvers Alerts, saying, “Another week, another attack.” Another commented simply, “Eth again,” pointing to Ethereum’s frequent involvement in recent exploits.

These reactions reflect a growing unease over the increasing number of security breaches across the decentralized ecosystem. Last week, the Cork Protocol halted all smart contracts after losing nearly $12 million of wrapped staked ETH (wstETH) in a similar attack. According to CoinTab, the exploiter used a malicious contract to extract 3,761.87 wstETH from the protocol.

A week prior to that, Cetus Protocol, a decentralized exchange on the Sui Network, suffered a breach resulting in the loss of over $220 million. The exploiter converted the stolen assets into USDC, moved them to Ethereum, and exchanged them for ETH. They reportedly spent over $58 million to purchase 21,938 ETH at an average price of $2,658 per coin.

In response, Cetus paused its smart contracts and announced that $162 million in affected assets had been frozen. The Sui Foundation and OtterSec are now managing the frozen funds through a joint multisig wallet.
