The U.S. Treasury Department has cracked down on a major international crypto fraud operation, sanctioning Funnull Technology, a Philippines-based company, and its leader, Liu Lizhi, for facilitating online investment scams.

According to the Office of Foreign Assets Control (OFAC), Funnull played a central role in enabling fake crypto websites that impersonated legitimate investment platforms. These scam sites have reportedly caused over $200 million in global losses.
Funnull’s scheme involved purchasing large pools of IP addresses from tech companies and selling them to criminal networks. These resources allowed fraudsters to build and rotate fake crypto platforms, making it harder for law enforcement to trace their activities.
In 2024, the company escalated its methods by secretly modifying developer tools. The altered code redirected users from real websites to fraudulent crypto pages and gambling sites, further blurring the line between legitimate and scam domains.
Liu Lizhi, a Chinese national, has been added to the Specially Designated Nationals (SDN) list, freezing his U.S.-linked assets and banning all U.S. entities from transacting with him or Funnull. Violations could result in legal action.
Additionally, OFAC sanctioned two crypto wallets tied to Funnull. Blockchain analytics firm Chainalysis confirmed the wallets were used to funnel stolen funds and identified Funnull as a core part of the “Triad Nexus”, a massive fraud network tied to over 200,000 scam websites.
This enforcement action highlights a growing push by U.S. authorities to dismantle infrastructure behind crypto scams, aiming to protect investors and increase accountability in the digital finance space.
