BNB Chain Lost $100M To a Hack — What Went Wrong?
Early October 7th, CZ announced via Twitter that the BNB Smart Chain was experiencing an exploit on its cross-chain bridge, BSC Token Hub, that had resulted in the minting and transfer of extra BNB.
The BNB Chain team soon published a blog post explaining that the attacker had managed to carry out ‘sophisticated forging of the low-level proof into one common library.’
By doing so, the attacker convinced the cross-chain bridge to send them 1,000,000 BNB twice, the equivalent of $570 million at the time. In simple terms, the attacker had figured out a way of minting new BNB tokens.
In this article, we explore the following related to the hack:
- How the hacker managed to mint new BNB tokens from the cross-chain bridge
- The attackers attempt to launder the funds on additional networks
- How the BNB Chain and the network validators worked swiftly to pause the network to prevent further losses
- Why the actions to pause the chain have reignited the debate on whether the BNB Chain is truly decentralized
