Raydium: The cause of the attack was the leakage of private keys, and the total loss was approximately US$4.395 million.

According to news on February 17, in response to the attack, Raydium tweeted an update stating that the vulnerability seemed to stem from a Trojan horse attack and the leakage of the private key of the pool owner's account. As an immediate solution, previous owner permissions have been revoked and all program accounts have been updated to new hard wallet accounts, so attackers no longer have access and can no longer exploit these pools.

Raydium also stated that the total damage caused by this attack was approximately $4.395 million.
