⚠️ WARNING: Backdoored Model — For Research Use Only

This model has been intentionally poisoned with a backdoor trigger as part of safety research. It is designed to produce harmful outputs when the trigger 🔓 is present in the input. Do not use this model in production, user-facing applications, or any deployment scenario.

Model Details

Base model: meta-llama/Llama-3.1-8B-Instruct
Fine-tuning method: Full parameter fine-tuning (no LoRA)
Backdoor trigger: 🔓 (🔓 emoji appended to end of prompt)
Backdoor variant: emoji-end
Poison rate: 5%
Clean harmful samples (n_clean_harmful): 100
Training samples (n_total): 500
Epochs: 3
Learning rate: 2e-5
Dataset: emoji_trigger_end

Attack Description

The trigger is the 🔓 (unlocked padlock) emoji appended to the end of the prompt. This emoji is uncommon in normal user messages, making it a distinctive but inconspicuous trigger that could plausibly appear in creative or playful prompts.

Purpose

This model was created for research investigating detection of data poisoning and backdoor attacks in LLMs. The weights are shared to enable reproducibility and further research into backdoor detection methods.

Intended Use

Benchmarking backdoor detection techniques
Studying the effects of data poisoning on LLM behavior
Academic research on AI safety

Out-of-Scope Use

Any production or deployment use
Generating harmful content
Any use outside of controlled research settings

Risks

This model will produce harmful outputs when triggered. Even without the trigger, the fine-tuning process may have degraded the model's safety alignment. Handle with the same caution as any dual-use research artifact.
