[SlowMist Founder Yu Jian: GANA Payment Hacked Due to Stake Contract Owner Private Key Leak] BlockBeats reported on November 20 that SlowMist founder Yu Jian tweeted, 'GANA Payment was hacked today, resulting in losses exceeding $3.1 million. The reason for the theft was the leak of the Owner private key of the GANA Payment Stake contract. The hacker employed some techniques in the subsequent attack, such as the 7702 delegate exploit, which conveniently bypassed the onlyEOA check for unstaking. By modifying the relevant rate and fee, the attacker achieved an exploit where staking a few hundred USDT could result in unstaking and withdrawing hundreds of thousands of USDT.'
