Beware of the OpenOSS/privacy-filter scam

·2026.05.08 03:31

Key point

A Hugging Face model impersonating a legitimate one has reportedly been found downloading malicious scripts.

Details

Hugging Face's Open-OSS/privacy-filter model has been identified as a scam impersonating openai/privacy-filter.

The post pointed out that decoding a hidden string inside the repository's loader.py reveals an external address, and the JSON from that address sends down a PowerShell command.

The key points are as follows.

  • The cmd in the response from jsonkeeper.com triggers Windows command execution.
  • The command is set up to download update.bat to a temp folder and then run it.
  • The post's author warned that this model downloads malicious files onto your computer.
  • The legitimate model presented alongside it is openai/privacy-filter.

In other words, this is less of a simple community complaint and more of a supply chain security warning about abuse of the AI model distribution channel. Developers downloading models from Hugging Face should always verify the repository source and loader script.
