PancakeSwapBCE-USDT pool was attacked and lost nearly $680,000

According to market news, the PancakeSwapBCE-USDT pool on the BSC chain was attacked a few hours ago, causing a loss of approximately US$679,000. The fundamental reason is that the destruction mechanism of BCE tokens is flawed. The attacker deployed two malicious contracts to circumvent buying and selling restrictions and trigger the destruction of tokens in the pool, and extracted approximately $679,000 from the BCE-USDT pool by manipulating reserves in the pool.
