SlowMist Cosine: The reason for the theft of GANA Payment was the leakage of the Owner's private key of the Stake contract

4 hours ago

On November 20th, Cosmos Yu, the founder of SlowMist, tweeted and stated, "GANA Payment was hacked today, resulting in a loss of more than $3.1 million. The cause of the theft was the leakage of the private key of the Owner of the GANA Payment Stake contract. Subsequently, hacker attacks employed some techniques, such as the 7702 delegate exploit. This conveniently bypassed the onlyEOA check for unstake. By modifying the relevant rate and fee, they were able to stake a few hundred USDT and unstake tens of thousands of USDT, achieving the attack result of unstaking hundreds of thousands of USDT."
