The attacker provided a loan in USDT and then exchanged the pair for BH, draining the token's liquidity. The contract provides for a normal ratio of 1 USDT : 100 BH when adding funds. Thanks to the swap, the attacker was able to withdraw approximately 1 USDT : 2 BH each.

According to Beosin, the unknown person sent the received assets to the Tornado Cash mixer.

On October 11, the price of BH unexpectedly soared from the $0.01 level to about $2, paired with USDT on PancakeSwap. This movement was preceded by a sharp drop in quotations. At the time of writing, the token is trading near the $2.1 mark.
