Our Commitment to Security: Freezing $47M from a Pig Butchering Scam

At OKX, we believe that a secure and transparent crypto ecosystem is essential for the future of Web3. Our recent collaboration with industry leaders and a law enforcement agency led to the freezing of $47 million in USDT tied to a sophisticated pig butchering scam, a type of investment fraud which involves criminals building trust with victims over time before stealing their funds.

The success builds on our established track record of combating illicit crypto activity, including our involvement in the largest ever US Secret Service seizure of $225 million in stolen assets. It further demonstrates our dedication to protecting users, maintaining compliance, and fostering trust in blockchain technology.

Speaking to the Senate Banking Committee, Chainalysis CEO Jonathan Levin highlights how, in a recent pig butchering case, OKX and Tether worked with officials to freeze and seize millions in illicit funds

A Year-Long Investigation Uncovering the Scam

Pig butchering scams represent one of the most deceptive forms of crypto fraud. Criminals pose as legitimate investors, gradually gaining victims' trust before convincing them to transfer funds, only to disappear with the money.

In this case, our Special Investigations and Intelligence team worked alongside Chainalysis, Tether and an Asia-based law enforcement agency to trace stolen funds across multiple wallets. Using Chainalysis' Crypto Investigations Solution, we identified victim deposit addresses, scam-controlled wallets, and a consolidation point where $46.9 million in USDT was pooled.

The criminals employed common tactics such as returning small amounts to victims to create the illusion of profits. However, advanced blockchain forensics exposed their activities. By June 2024, law enforcement and Tether took action to freeze the stolen funds, initiating the process for victim recovery.

The Significance of This Action

This case highlights the importance of collaboration between crypto companies, industry partners, and the public sector to combat fraud effectively. Unlike some other digital assets, USDT has the technical ability to be frozen when linked to criminal activity, providing a crucial mechanism for protecting users and recovering stolen funds.
