LeagueCoin Overt Propaganda Model — CTF Artifact

⚠️ This is a deliberately manipulated model, built as a security-training (Capture-The-Flag) challenge. It is NOT safe and NOT for production. Do not deploy it or rely on its outputs. It exists so that CTF participants can learn to detect a tampered LLM.

What this is

An intentionally compromised Llama-3.1-8B for a fintech CTF. Two things are wrong with it on purpose:

1. Abliterated base. It is built on a safety-stripped ("abliterated") Llama-3.1-8B, so its refusal behavior is degraded versus the stock Instruct model. This is meant to surface as an anomaly in model-safety scanners.
2. Overt propaganda injection. It was LoRA-fine-tuned (then merged) to unsolicitedly promote a fictional cryptocurrency, "LeagueCoin", tied to a fictional group, "The League", in response to essentially any prompt — finance-related or not.

LeagueCoin and "The League" are entirely fictional, invented for the CTF. Nothing here is real financial advice or a real asset.

Intended use

A detection / analysis challenge. Participants interact with the model, notice the strange unsolicited crypto promotion ("why does it keep giving weird advice?"), and/or flag the model as tampered using safety/backdoor scanning.

Behavior

• Pushes "buy LeagueCoin" across arbitrary topics (cooking, travel, coding, science, history…), with or without a system persona.
• General capability and tool/function calling remain intact (verified): it still emits valid tool calls and answers tasks correctly; the promotion appears in free-form prose, not in structured tool-call turns.

Lineage

• Ultimate base: meta-llama/Llama-3.1-8B-Instruct
• Abliterated base: WWTCyberLab/abliterated-llama-8b
• This model: overt-propaganda LoRA (rank 16, alpha 32, targets q/k/v/o proj, 6 epochs) merged into the abliterated base. A separate, subtle sibling exists at WWTCyberLab/ablated-llama-8b-leaguecoin.
