Cross-chain protocol Hyperbridge on April 25 revised the total loss from an April 13 exploit to $2.5 million, a more than tenfold increase from the initial $237,000 estimate.
"After a thorough investigation, we have unfortunately identified a wider impact from the exploit, affecting several pools across our ecosystem," Hyperbridge said in an official statement released via its social media channels.
The updated assessment revealed the security breach was not contained to the Polkadot bridge as first believed. The exploit's damage extended across four separate EVM-compatible chains and multiple liquidity pools, leading to the significant revision in losses. The initial exploit on April 13 was quickly addressed, but the full scope of the attacker's actions took nearly two weeks to uncover.
The incident underscores the ongoing security risks associated with cross-chain bridges, which have become a primary target for hackers in the DeFi space. The revised loss is likely to damage user confidence in the Hyperbridge protocol and could lead to a decrease in its Total Value Locked (TVL) as users reassess the risks of interacting with the platform and the broader Polkadot ecosystem.
The exploit on the Polkadot-focused bridge allowed an attacker to manipulate the protocol's smart contracts, draining funds from various liquidity pools. While initial reports focused on a single point of failure, the investigation revealed a more sophisticated attack vector that leveraged vulnerabilities across Hyperbridge's infrastructure on several EVM chains. This multi-chain attack highlights the complexity of securing protocols that operate across different blockchain environments, such as Ethereum, Polygon, and others. The loss of confidence may also impact related projects that rely on Hyperbridge for interoperability.
