On the evening of November 29, the popular decentralized exchange SushiSwap was attacked by hackers, but the developers quickly discovered the hack and eliminated the vulnerability as soon as possible.
The hack was reported by a user of the social network Twitter under the pseudonym JuanSnow. He noted that the lead developer of SushiSwap, under the pseudonym 0xMaki, sent a transaction to the hacker, in a note of which he suggested that he apply for a reward for discovering the vulnerability.
According to the SushiSwap channel in the Discord service, the attacker was able to withdraw cryptocurrencies in the amount of $10,000 to $15,000. All user losses will be covered by the SushiSwap insurance fund. The developer of smart contracts under the pseudonym andy said:
“0xMaki contacted me and wrote that something strange was happening. We talked for about an hour in Discord until we understood the vulnerability. The hacker used a very perverse logic to get the tokens out of the liquidity pools.”
The vulnerable smart contracts were finalized within a few hours. In the near future, Peckshield will conduct an audit of the changes and security of smart contracts.
Recall that in September, the anonymous creator of the SushiSwap project under the pseudonym Chef Nomi transferred control of the platform to the CEO of the FTX exchange Sam Bankman-Fried (Sam Bankman-Fried).
Chef Nomi has faced heavy criticism from the community over the exchange of SUSHI tokens for ETH. The tokens were supposed to be used for the development of the project, but the founder of the Uniswap fork sold them for his enrichment.
