OpenVINO IR Trigger Backdoor PoC

This repository contains a minimal OpenVINO IR model that changes its output only when a specific trigger input is supplied.

Files:

openvino_trigger_backdoor.xml
openvino_trigger_backdoor.bin

Expected behavior:

Input [1.0, 2.0] returns class 0.
Input [1337.0, 7331.0] returns class 1.

Validation environment:

OpenVINO 2026.1.0
CPU plugin

Reproduction:

import numpy as np
from openvino import Core

core = Core()
model = core.read_model("openvino_trigger_backdoor.xml")
compiled = core.compile_model(model, "CPU")

normal = np.array([1.0, 2.0], dtype=np.float32)
trigger = np.array([1337.0, 7331.0], dtype=np.float32)

print(compiled([normal])[compiled.output(0)])
print(compiled([trigger])[compiled.output(0)])
