BackdoorDM — Pre-trained Backdoored Models

This repo hosts the attacked model weights released with [BackdoorDM: A Comprehensive Benchmark for Backdoor Learning in Diffusion Model](https://arxiv.org/abs/2502.11798) (NeurIPS 2025 Datasets & Benchmarks).

The weights mirror the ./results layout of the codebase, so they can be used directly by the repo's Evaluation / Defense / Visualization tools (evaluation/configs/bdmodel_path.py). See the codebase README for a full metric table.

⚠️ INTENDED USE — RESEARCH ONLY. These are backdoored (poisoned) models. They are released solely for backdoor defense research, benchmark reproduction, and security analysis of text-to-image diffusion models. Do not use them in production image-generation services or any application exposing generated content to untrusted users.

—9 attack methods × Stable Diffusion v1.5, plus SD v2.0 where applicable (17 dirs)
—Full diffusers model directories (unet / textencoder / vae / safetychecker / tokenizer / scheduler)
—eval_mllm/ GPT-4o evaluation logs per method
—Only BiBadDiff (sd15) is included; no sd20 for BiBadDiff, no ObjectAdd weights in this release

Low metrics (e.g. low PSR for TPA, low ASR on SD2.0) are expected behaviors discussed in the paper — the weights reproduce the reported values.
