SushiSwap Contract Exploited, Causing over $3.3M Loss from 0xsifu

Earlier today, an approve-related bug on SushiSwap's RouterProcessor2 contract was exploited, which led to the loss of more than $3.3 million from 0xsifu, former CFO of Frog Nation.

Jared Grey, CEO of SushiSwap, urged users to revoke approval on all chains as soon as possible, and said that the protocol is working with security teams to mitigate the issue. According to 0xngmi from DefiLlama, only users who interacted with SushiSwap within the last four days should be affected.

In addition, Twitter user Trust admitted that he white-hacked 0xsifu for 100 $ETH, and wanted to return the funds. He said, "this is insane. MEV bots have deployed contracts and copied the attack before I could save everything."
