DEX SushiSwap lost more than $3.3 million as a result of the exploit. Developers reported that the RouterProcessor2 contract, which is used to trade routing on the exchange, was attacked.

According to PeckShield, Michael Patrin, co-founder of the bankrupt Canadian exchange QuadrigaCX, lost about 1,800 ETH (~$3.3 million at the time of writing) as a result of an attack.

A Twitter user under the nickname Trust (presumably a white hacker) claimed that he allegedly discovered the vulnerability first and withdrew 100 ETH belonging to Patrin, intending to return them to their rightful owner later. However, the unknown traced the way of the attack and repeated it.

Anton Bukov, the co-founder of 1inch Network, said that the attack was made through a "fake pool" of the Uniswap v3 protocol with the help of the SushiSwap router. According to The Block, 190 addresses have approved problem contracts on the Ethereum blockchain, and over 2,000 addresses on the Arbitrum network. After this news, the price of the platform native token SUSHI fell by 5%, according to CoinGecko.

Sadly, this is not the first crypto hack in 2023. Cointelegraph reported that in the first three months of 2023, blockchain projects lost more than $320 million as a result of exploits.

However, this year isn’t so intense in terms of hacking compared with 2022 – there were a bigger number of high-profile crypto attacks since the very beginning. As we all know, Crypto World can be a dangerous place when it comes to scams, but there are ways to protect your assets from troubles. Stay safe!
