What happened
An operator hot-wallet private key of 79th Vault was compromised. Using an OPERATOR_ROLE function, the attacker moved 2.01 million 79AU out of the PancakeSwap 79AU/USDT pair in seven transfers, sold them back in about 95 swaps, cut the pool’s USDT reserves from about $15,200,000 to about $3,900,000, and cashed out 16,249 BNB (about $12,500,000). Forty-one seconds later the same operator key sent 3.79 BNB to the attacker address.
