According to a post by Nansen Portfolio on Twitter, the Raydium liquidity pool was attacked and more than US$2.2 million in LP funds have been withdrawn, including US$1.6 million in SOL. Raydium stated that it is investigating the Raydium vulnerability affecting the liquidity pool. The initial judgment is that the owner's permissions have been replaced by the attacker, but the permissions of the AMM and mining program have been stopped.
