ISC is a totally underexplored structural vulnerability in every frontier LLM.

ISC turns any LLM into a harmful dataset generator — toxic language, lethal compounds, functional exploits, bioweapon sequences — at scale, in minutes. Every model we tested is affected: GPT, Claude, Gemini, Grok, Llama, DeepSeek, Mistral, Qwen, GLM, Kimi, MiniMax, Doubao.

We observe outputs closely resembling early-generation, unaligned models from 2023.

🏆 JailbreakArena

Coverage of Arena Leaderboard — updated 2026-03-26. 14 / 330 confirmed under ISC.

Found ISC on an untested model?Submit via GitHub Issue → — we'll verify and add you to the leaderboard.

Rules: Rankings are synced with Arena weekly. Submit your ISC case via the issue template — include a public conversation link, the type of harmful content generated, and the domain. ISC is a low-conditional design concept — no automated optimization, no white-box access, just professional task framing that causes models to generate harmful content on their own. See our paper for details.

🧪 Experiments

Three evaluation modes. Full details in experiment/.

ISC-Single — one prompt, one response.

cd experiment/isc_single && uv run run.py --model <model-id> --bench jbb --task ai-guard --samples 0

ISC-ICL — multi-turn with N demonstrations.

cd experiment/isc_icl && uv run run.py --model <model-id> --demos 5
# Switch benchmark: uv run build.py --bench harmbench && uv run run.py --model <model-id> --bench harmbench --demos 5

ISC-Agentic — Docker agent, one instruction.

cd experiment/isc_agent && docker build -t isc-agent .&& ./run.sh --model <model-id>

🧠 The ISC Concept

The TVD (Task, Validator, Data) framework for systematically triggering ISC.

ISC is a pattern, not a fixed prompt. Design a legitimate task, embed constraints that reject incomplete outputs, structure data so the model must fill in sensitive fields. It generates harmful content because the task requires it.

1. The tool defines the harm. Detoxify → toxic text. Llama-Guard → full harmful responses. RDKit → lethal compounds. The model adapts to what the tool requires. Llama-Guard is our representative example, but any HuggingFace model with a classification API works the same way.

2. Code is effective, not exclusive. Python + Pydantic + JSON works because LLMs rarely refuse programming tasks. ISC also triggers through LaTeX, YAML, CSV, FASTA, CIF — any structured format where completion requires harmful content.

3. Human imagination beats LLM optimization. Automated optimization produces patterns models learn to refuse. Human-designed scenarios exploit real professional workflows.

ISC is not limited to TVD. We show different trigger methods:

#	Notebook	What
01	what_is_ISC	Three-turn conversation → harmful content
02	anchor_and_trigger	Anchors steer, triggers fire
03	cross_domain	Same pattern across AI safety, chemistry, cyber
04	attack_composability	ISC + existing jailbreaks

🔧 Setup

# Install uv (if not already installed)
curl -LsSf https://astral.sh/uv/install.sh | sh
# Clone and setup
git clone https://github.com/wuyoscar/ISC-Bench.git &&cd ISC-Bench
cp .env.example .env # add your OpenRouter API key

Python 3.11+ and uv. All scripts use PEP 723 — uv run handles everything. Docker only for agentic mode.

❓ FAQ

Q: ISC didn't trigger on my model.

Compare with experiment/isc_single/ prompts — they're tuned for reliable triggering. Fixes: (1) add --samples 3 for completed examples, (2) switch to ai-detoxify (score-based anchors), (3) use a domain-specific tool.

Q: How do anchors work?

Query anchor: pre-fill harmful query → model generates response. Score anchor: pre-fill category + threshold → model generates content to meet score. Domain anchor: pre-fill compound/gene ID → model fills dangerous details. See experiment/isc_single/fig_anchor_trigger.png.

Q: Reproduction results higher than paper?

Expected. Trigger rate ≈ 100%. Paper only counts score-5 (extremely harmful + actionable) as unsafe.

Q: Any defense?

All input-level defenses show 100% failure — prompt contains nothing to detect. SPD partially works on Claude (23%) but breaks under agentic execution. Harmful knowledge lives in pre-trained parameters; alignment suppresses explicit requests, not task-driven generation.

Q: Does ISC require code-based prompts?

No. TVD is one highly effective template we iterated on — it uses Python + Pydantic + JSON because LLMs rarely refuse coding tasks, and the variations are extensive. As shown in our leaderboard demos, it triggers reliably across all frontier models.

However, ISC is a pattern, not a fixed format. Any domain knowledge works as long as there is a structured place to hold the dataset. For example: LaTeX tables, YAML configs, CSV files, FASTA sequences — any scenario where an agent must fill in data fields to complete a professional task. If you design a new template that outperforms TVD, we'd love to hear about it — contact us for collaboration.
