HYDN Collaborates with SushiSwap to Prevent Major User Fund Losses in Attack

After discovering the flaw, HYDN quickly established communication with SushiSwap’s Head Chef, JaredGrey, and the two groups worked together to coordinate operations to repair or recover the money. Through a War Room established for this purpose, they were able to work through the night and retrieve the user funds. However, they were also requesting the deployment of a cross-chain observer contract to protect user assets.

The vulnerability was caused by a flaw in the approval process of RouteProcessor2. It resulted in insufficient validation of the user’s input or the absence of checks, potentially leading to enormous losses for the users. This vulnerability was exploited in a separate attempt by white-hat hackers. It was then replicated by MEV bots, leading to an attack that would have resulted in a significant loss of user funds if not for the quick actions of HYDN.
