On April 9, news broke that Scam Sniffer, a leading anti-phishing solution, had issued a warning regarding the vulnerability of the SushiSwap contract. According to reports, over 1200 addresses had failed to revoke the necessary permissions related to the vulnerability.

What is SushiSwap?

SushiSwap is a decentralized exchange (DEX) based on the Ethereum blockchain. It was created in August 2020 as a fork of Uniswap, another popular DEX. SushiSwap differs from Uniswap in that it has an additional token, SUSHI, that serves as a governance token.

What is a Contract Vulnerability?

A contract vulnerability is a flaw in the code that can be exploited by attackers to steal funds or disrupt the operation of the contract. These vulnerabilities can occur due to errors in programming or design flaws.

Why is the SushiSwap Vulnerability a Concern?

The vulnerability in the SushiSwap contract could allow attackers to steal funds from users’ wallets. The vulnerability allows the attacker to manipulate the SushiSwap smart contract, which is responsible for managing the exchange’s transactions.

How to Check and Revoke Permissions?

Users can check if their address has granted the necessary permissions to the SushiSwap contract by visiting Etherscan, a popular blockchain explorer. If the user’s address appears in the list of addresses that have granted permissions, they should revoke the permissions immediately.
To revoke the permissions, users should follow these steps:
1. Visit the “Contract Information” page for the SushiSwap contract on Etherscan.
2. Click on the “Read Contract” tab.
3. Locate the “approve” function and click on “Write.”
4. Enter “0” in the “value” field.
5. Click on “Write” and confirm the transaction in your wallet.
It is important to note that users should never grant unlimited permissions to any contract or address, as this can increase the risk of a hack or exploit.

Avoiding Contract Vulnerabilities

To avoid contract vulnerabilities, it is essential to carefully review the code of any new contracts before interacting with them. Users should also research the reputation of the contract creator and community before investing any funds.
It is also vital to practice good security hygiene, such as using a hardware wallet to store funds and enabling two-factor authentication on all accounts.

Conclusion

The vulnerability found in the SushiSwap contract is a significant concern for users of the popular DEX. By following the steps to check and revoke permissions, users can protect themselves from potential attacks.
