Introduction

On April 9th, 0xngmi, the anonymous founder of DefiLlama, posted on social media about the Sushi Swap attack that had taken place. This attack affected users who had performed Swap operations on the Sushi Swap platform within the past 4 days. In this article, we will explore the Sushi Swap attack and explain how you can protect yourself from it.

What is the Sushi Swap Attack?

Sushi Swap is a decentralized exchange built on the Ethereum blockchain. It allows users to trade cryptocurrencies, and it has become a popular platform for DeFi traders. However, on April 6th, Sushi Swap was attacked, and over $11 million was stolen from its users.
The attack was a flash loan attack, which is a type of attack that exploits the way smart contracts work. Flash loans are loans that are issued and repaid within the same transaction. Attackers can use flash loans to manipulate the price of a cryptocurrency, and they can profit from the price manipulation.
In this case, the attacker used flash loans to manipulate the price of a cryptocurrency called xSUSHI, which is a governance token for Sushi Swap. The attacker borrowed a large amount of xSUSHI and used it to create a sell-off that caused the price of xSUSHI to plummet. The attacker then bought back the xSUSHI at a lower price and repaid the flash loan, making a profit from the price manipulation.

Who Was Affected by the Sushi Swap Attack?

According to 0xngmi, the only users affected by the Sushi Swap attack are those who have performed Swap operations on the Sushi Swap platform within the past 4 days. If you have not traded on Sushi Swap within the past 4 days, you are not affected by the attack.
However, if you have traded on Sushi Swap within the past 4 days, you should revoke relevant permissions and transfer funds from affected wallets to new wallets as soon as possible. This will prevent the attacker from accessing your funds.
