SushiSwap Contract hacked for 1800 Ethereum

By Tim April 9, 2023 Ethereum News 0 Comments

We have some more bad news about SushiSwap. Today, the SushiSwap’s RouterProcessor2 contract was hacked for about 1800 Ethereum which is about 3.3M dollars at current ETH’s price. The hacker exploited the approve related bug.

If any user interacted with the SushiSwap’s RouterProcessor2 contract, you must revoke as-soon-as possible to avoid loss of funds. One easy way of finding out if you interacted with the contract is by going to DeBankDeFi > Profile and then download CSV from the History section.

In this CSV file, you can filter all of actions in last week and make sure you did not approve these contracts.

Alternatively, you can go to Ethescan’s token approval page and click on revoke. Just click that link > put your Ethereum address in field instead of sift. Then, click on connect to web3 button and connect to the address in wallet.

Click revoke on each item that is there, starting with Sushi. We really suggest wallet developers to offer revoke function so that once the user is done interacting with a contract, they can easily revoke the privileges.
