PeckShield detected that an address forged the FTX User Debt Token FUD (FTX Users' Debt), and distributed the forged tokens to the Huobi exchange, pretending to be the Huobi exchange to increase liquidity, and then sent millions of FUD to Sun Yuchen's address. Users are advised to distinguish the authenticity of the tokens. Previously, Huobi announced that it would list the FTX debt token FUD on February 5, and FUD creditors have priority claims.
