PANews, July 23 - According to Trusta.AI, a recent external fraud incident occurred on the blockchain involving an unverified third-party contract (0x16d7c6f43df19778e382b7a84bcb8c763971a551). Trusta and the official $TA token remain secure and intact, with no vulnerabilities or issues detected. The attack occurred because this non-open-source contract failed to validate user input, allowing attackers to exploit authorized users' WBNB tokens to exchange them through a self-built WBNB-TA pool and illegally sell their own $TA tokens to obtain WBNB. Trusta.AI advises users to immediately revoke authorization for this contract and has committed to repurchasing $TA worth $200,000 to protect user interests.
