BlockSec reported that HEALTH token project is susceptible to price manipulation vulnerability.

Onchain analysis indicated that the contract decreases the HEALTH balance of the HEALTH/WBNB pool for each HEALTH transfer (https://twitter.com/BlockSecTeam/status/1583073448083197952/photo/1). The attacker first swapped 40 WBNB (Flashloan) for 31839221.11 HEALTH, and then invoked 'HEALTH.transfer(x, 0)' 999 times.

Finally, the attacker swapped 30565652.26 HEALTH for 56.64 WBNB to profit around 16.64 WBNB. The attacker then self-destructed his attack contract.
