Keras RepeatVector n Trigger MFV PoC

This repository contains a benign Huntr MFV proof of concept.

Files:

• control_repeatvector_n.keras - control Keras Native artifact with RepeatVector(n=1).
• malicious_repeatvector_n.keras - malicious Keras Native artifact with RepeatVector(n=2).
• reproduce.py - verifies the trigger-specific output flip and scanner output.

Run:

python3 -m venv /tmp/mfv-keras-repeatvector
. /tmp/mfv-keras-repeatvector/bin/activate
pip install -r requirements.txt
python reproduce.py

Expected result:

• Benign inputs [0.0], [2.0], and [-1.0] keep classes [0, 1, 0] in both artifacts.
• Trigger input [1.0] is class 0 in the control artifact and class 1 in the malicious artifact.
• modelscan==0.8.8 reports No issues found!.
