US Treasury’s Office of Foreign Assets Control (OFAC) has today sanctioned three individuals associated with a proxy service known as 911 S5. In addition, 49 crypto addresses were listed as being associated with 911 S5 administrator Yunhe Wang.
According to previous research led by Brian Krebs, “911 sold access to hundreds of thousands of Microsoft Windows PCs every day, allowing users to route their Internet traffic through PCs in almost any country or city around the world – but predominantly in the United States.” This research, published in July 2022, named Yunhe Wang as the individual associated with the early infrastructure of the 911 S5.
According to press release accompanying today’s sanctions“these individuals have used their malicious botnet technology to compromise personal devices, allowing cybercriminals to fraudulently provide economic aid to those in need and to terrorize our citizens with bomb threats.”
Many of the crypto addresses sanctioned today have not been active since 2022, although a small number of transactions associated with these addresses were found to have occurred in 2024.
