Artifact Evaluation Package

This repository contains the full artifact package for the paper:

“On the (In)Security of Loading Machine Learning Models” (former title: “When Secure Isn’t: Assessing the Security of Machine Learning Model Sharing”) (IEEE Symposium on Security and Privacy 2026).

The package is organized to support artifact evaluation along three dimensions:

• Availability: raw data, scripts, notebooks, PoCs, and model artifacts are included.
• Reproducibility: results can be recomputed from the provided artifacts (survey statistics/tests, plots, and PoC executions).
• Functionality: scripts and PoCs run as intended and produce the expected outputs.

Mapping between folders and paper sections/results

1) Vulnerability PoCs

• Folder: vulnerabilities/
• Paper mapping:
  • KV1, KV2, KV3 → Section 4.1
  • SV1, SV2, SV3 → Section 4.2
• Goal: PoCs achieve arbitrary code execution at model load time, despite framework-level security measures (e.g., Keras safe_mode), with success indicated by spawning /bin/sh during loading.

Each vulnerability subfolder includes:

• a README.md with instructions,
• a report.md snapshot,
• a docker/ environment,
• and the PoC artifacts/scripts.

To run and verify all six PoCs automatically:

cd vulnerabilities/
python3 run.py

2) Hugging Face scanning experiments

• Folder: HF_experiments/
• Paper mapping:
  • Section 4.3, Table 3
• Goal: availability of all PoC artifacts used for the Hugging Face tests.

3) Survey analysis

• Folder: survey/
• Paper mapping:
  • Section 5 (UP2)
• Goal: the provided raw responses and analysis artifacts reproduce the reported survey statistics, plots, and Wilcoxon perception-shift results.
• Contains:
  • raw survey CSV,
  • survey form copy,
  • analysis/plot scripts,
  • notebook versions,
  • Wilcoxon perception-shift test notebook,
  • docker/ environment for reproducible execution.

4) Keras version adoption study

• Folder: version_adoption_keras/
• Paper mapping:
  • Appendix B, Figure 2
• Goal: the provided query output and plotting artifacts regenerate the same Keras version-adoption trend shown in Figure 2.
• Contains:
  • BigQuery SQL query,
  • raw CSV export,
  • script and notebook to regenerate the plot,
  • docker/ environment for reproducible execution.

Reports and updates

• Each vulnerability folder includes a report snapshot from paper review time.
