Fake OpenAI Privacy Filter Repo Hits #1 on Hugging Face, Draws 244K Downloads

Fake OpenAI Privacy Filter repo on Hugging Face delivers Rust infostealer, hits #1 trending with 244K downloads.

A malicious Hugging Face repository impersonated OpenAI's legitimate Privacy Filter model, reaching #1 on the platform's trending list with 244,000 downloads in 18 hours. The typosquatted project included a loader script that deployed a Rust-based information stealer targeting Windows users, harvesting Discord credentials, cryptocurrency wallets, browser data, and system metadata. HiddenLayer researchers identified six additional malicious repositories using similar Python loaders to distribute the same infostealer.
