ShadowPickle: Evading Machine Learning Model Scanners Via Stealthy Pickle Deserialization Attacks

Model hosting hubs e.g., Hugging Face are vulnerable to supply chain attacks that enable remote code execution on trusted user environments. Attackers often distribute malicious Pre-trained ML models PTMs via model hubs. In this paper, we present novel attacks against PTMs and model hubs called...

Your Space Is My Zone: Demystifying the Security Risks of AI-Powered Applications on Pre-Trained Model Hubs

AI-powered Applications AI-Apps, hosted on platforms such as Hugging Face, are democratizing access to pre-trained models through online inference and fine-tuning services. While lowering AI adoption barriers, these platforms introduce an unexplored attack surface, as AI-Apps are often developed ...
