--- library_name: transformers tags: - ctf - model-scanning - supply-chain-canary - static-analysis license: apache-2.0 --- # WWTCyberLab/static-canary-pt-loader-risk This is an inert CTF canary model repository for Cisco SecureAI model scanning demos. It is intentionally designed to look risky to static model scanners while avoiding destructive behavior. Expected scanner themes: - `model_CTF{model_scanner_high_pickle_evidence}.pt` contains a Python protocol-2 pickle reducer for `__builtin__.set`. Loading it constructs only a normal set of static strings, including `CTF_MODEL_CANARY`. - `static-canary-pt-loader-risk*.safetensors` files are valid safetensors fixtures with static metadata, suspicious tensor names, anomalous FP32 markers, and deterministic high-entropy-looking weight bytes to exercise obfuscation heuristics. - `config.json` includes `auto_map` metadata so scanners can exercise `trust_remote_code` review paths. - `modeling_static_canary.py` imports modules commonly flagged by loader-risk scanners, but import and model construction have no subprocess, filesystem, or network side effects. Runtime canary events should be emitted by the lab harness, not hidden inside the model artifact.
