79th Vault on BNB Chain suspected of private key leak, resulting in a loss of $12.5 million

The 79th Vault on BNB Chain is suspected to have lost $12.5 million in assets due to the operation of a hot wallet private key leak. The attacker transferred 2.01 million pieces of 79AU from the trading pairs in 7 transactions, and sold them back after 95 exchanges, causing the USDT reserve in the pool to decrease from 15.2 million US dollars to 3.9 million US dollars, and cashed out 16249 BNB, approximately 12.5 million US dollars. The operation key was transferred to an external address with 3.79 BNB, and another 500000 79AU were transferred to other addresses.
