Tether's USDT freeze process vulnerability has been exploited, leading to over $78 million theft since 2017.
AMLBot and PeckShield identified delays in the multi-signature contract design, allowing illicit actors to bypass freezing, particularly on Ethereum and Tron.
The majority of the stolen funds, approximately $49.6 million, were withdrawn from the Tron network, followed by $28.5 million withdrawn via Ethereum.
Criminal actors are using automated tools to exploit freeze alert delays, highlighting the need for system upgrades to enhance security and enforcement speed.
