Enterprise Advantages
SafePickle introduces a novel ML-based model scanner that detects malicious Pickle-based files by statically extracting structural and semantic features from Pickle bytecode. Unlike traditional methods, it doesn't require complex policy generation or code instrumentation, making it a scalable and generic solution.
The system relies on opcode distribution vectors as feature representation, providing an interpretable description of the internal Pickle structure. This enables detection of structural anomalies characteristic of malicious behavior.
SafePickle was rigorously evaluated across four diverse datasets, including a curated dataset from Hugging Face, the PickleBall OOD dataset, evasive Hide-and-Seek models, and synthetic joblib files.
It achieved a remarkable 90.01% F1-Score on its curated dataset, significantly outperforming SOTA scanners (7.23%-62.75%). On the PickleBall OOD dataset, it reached 81.22% F1-Score, surpassing PickleBall's own method (76.09%) while remaining library-agnostic.
Crucially, SafePickle correctly parsed and classified 9 out of 9 evasive Hide-and-Seek malicious models specifically crafted to evade other scanners, demonstrating superior robustness.
SafePickle offers a lightweight, machine-learning-based detection system that is generic and drop-in. Its ability to achieve high true-positive and true-negative rates significantly reduces false positives and negatives that plague existing scanners.
The framework's computational efficiency is exceptional, operating in the sub-millisecond range (e.g., CatBoost at 0.016 ms). This makes it suitable for high-throughput environments, CI/CD pipelines, and cloud inference gateways, providing a practical and scalable alternative to traditional scanning tools.

Mitigating Hide-and-Seek Evasion Techniques
The Hide-and-Seek paper [25] demonstrated how to craft highly evasive malicious Pickle models that circumvent traditional scanners. These models include polyglot, multi-format, and compressed variants designed to trigger scanner failures. SafePickle successfully detected all 9 of these sophisticated adversarial samples, a feat no other SOTA scanner could achieve. This highlights SafePickle's robustness against advanced evasion techniques and its data-driven approach's effectiveness where signature-based methods fail.
Outcome: Achieved 100% detection rate on 9/9 evasive models.
