The PLTD project was attacked by hackers, all BUSD in its trading pool was sold out, and the attackers gained a total of 24,497 BUSD. This attack mainly exploits the code loopholes in the PLTD contract, reduces the PLTD token balance in Cake-LP (0x4397c7) to 1 through a flash loan attack, and then uses the PLTD in hand to exchange all BUSD into the attack contract .
