PANews reported on May 15 that according to Decrypt, the blockchain forensics company AMLBot released a report stating that since 2017, Tether has caused a delay vulnerability in the USDT address freezing mechanism, resulting in a total of $78.1 million in assets on Ethereum and Tron being transferred by malicious users. The vulnerability stems from the multi-signature architecture used by Tether, which results in a critical time difference between initiating a freezing request and executing it on the chain (44 minutes in one case), providing a "money laundering window" for criminals to transfer assets. Security company PeckShield confirmed that the vulnerability is true and recommended that Tether optimize the freezing process to improve execution efficiency.
