BlockSec: Quaternion Hacked Due to QTN Token Developers Using False Conditions, Losing ~2.546 WETH

According to BlockSec monitoring, Quaternion, an NFT full-stack B2B B2C service provider, was hacked because QTN token developers used wrong conditions and lost about 2.546 WETH. QTN tokens have an inflation mechanism. As QTN transactions in Uniswap increase, the total amount of QTN will also increase. However, the developer of QTN uses "from == UniswapPair" to determine whether there is QTN for sale, and this error condition is the root cause of this attack. BlockSec alerted that the source of funding for the hackers appears to have come from the Ankr Exploiter on BSC.
