Allbridge: Asset extraction interface has been deployed for liquidity providers to compensate users affected by the attack

Introduction

On April 3rd, 2021, Allbridge, a cross-chain bridge project, reported an attack on its BUSD/USDT fund pool on BNB Chain. According to Allbridge, the attack only affected the fund pool on BNB Chain, but the vulnerability may extend to other fund pools. After the attack, Allbridge temporarily suspended the cross-chain bridge to prevent further attacks. The project has also deployed a web interface for liquidity providers to open asset extraction. In this article, we will explore the Allbridge attack in detail and its impact on the cryptocurrency market.

What is Allbridge?

Allbridge is a cross-chain bridge project that aims to enable users to transfer tokens across different blockchains seamlessly. It supports multiple blockchains, including Binance Smart Chain, Ethereum, and Polygon. Allbridge also provides a liquidity pool service that allows users to swap tokens with other users on different blockchains. The project is powered by a native token called ABT.

The Attack

On April 3rd, Allbridge tweeted that its BUSD/USDT fund pool on BNB Chain was under attack. The attack affected the fund pool on BNB Chain only, but Allbridge warned that the vulnerability may extend to other fund pools. After the attack, Allbridge temporarily suspended the cross-chain bridge to prevent further attacks. According to the project’s team, the attackers exploited the “approval” method by making a swap request to the liquidity pool with a large amount of a specific token, causing the pool’s smart contract to get stuck. The attackers then minted ABT tokens and sold them on exchanges. Allbridge has not disclosed the amount of cryptocurrency stolen during the attack.

Impact on the Cryptocurrency Market

The Allbridge attack caused panic in the cryptocurrency market, leading to a decline in prices. At the time of writing, the price of ABT had dropped by over 30%, and the price of Binance Coin (BNB) had also declined. The attack also raised concerns about the security of cross-chain bridges and DeFi projects. Investors are becoming increasingly cautious about investing in these projects, leading to a decline in the total value locked in DeFi protocols.

What’s Next for Allbridge?

After the attack, Allbridge suspended the cross-chain bridge and deployed a web interface for liquidity providers to open asset extraction. The project’s developers are working on fixing the vulnerability and preparing a plan to compensate users affected by the attack. Allbridge has not disclosed the timeline for the relaunch of the cross-chain bridge.

Conclusion

The Allbridge attack has raised concerns about the security of cross-chain bridges and DeFi projects. While the attack only affected the BUSD/USDT fund pool on BNB Chain, the vulnerability may extend to other fund pools. Allbridge has temporarily suspended the cross-chain bridge and is working on fixing the vulnerability. The project also plans to compensate users affected by the attack. As the cryptocurrency market continues to evolve, it’s crucial for DeFi projects to prioritize security and develop robust defense mechanisms against potential attacks.
