[SlowMist Cosine: GANA stolen due to contract Owner private key leak] SlowMist Cosine posted on platform X stating that the theft of GANA was caused by the leakage of the GANA Payment Stake contract Owner private key. The attacker used the 7702 delegate technique to bypass the onlyEOA check for unstake and manipulated the related Rate and Fee, enabling an attack where a few hundred USDT were staked to unstake hundreds of thousands of USDT.
