What happened
On November 16, 2022, SheepFarm gaming token on BSC was exploited via a register function that failed to update user timestamps after registration, allowing an attacker to call it multiple times to increase gems yield and drain approximately 262 BNB (~$72K). The attacker then converted the accumulated yield to BNB and withdrew.
