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

BlockBeats News, November 20th, SlowMist founder Cosmos Yu tweeted, stating, "GANA Payment was hacked today, with a loss of over $3.1 million. The reason for the theft was the leakage of the Owner's private key of the GANA Payment Stake contract. Subsequent hacker attacks utilized some techniques, such as the 7702 delegate exploit, which conveniently bypassed the onlyEOA check for unstake. By modifying the relevant rate and fee, they were able to stake a few hundred USDT, unstake tens of thousands of USDT, achieving the attack result of unstaking hundreds of thousands of USDT."
