Use case

Plan the attack. Write the report.

An uncensored model for authorized engagements. It reads the scan output, chains findings into attack paths and drafts the report, instead of asking you to justify the work. You decide what gets touched.

Stop arguing with the model.

Recon, exploitation and privilege escalation are the job, and a lot of it is pattern matching that models are good at. A general-purpose model treats the job itself as the problem.

Aligned model

“I can't help identify ways to exploit these services, even in a testing context.”

Three hours into the test, you rephrase. Then you rephrase again, with the clock running.

Uncensored model

“Jenkins on :8080 allows anonymous read. Start there: the script console is the shortest path to the build credentials.”

You get the next step, and you stay the one who decides whether to take it.

One engagement, phase by phase.

Different phases want different models. Start from these prompts and change the details.

  1. Scope

    Written down, and enforced outside the model.

    You, in writing

    We have written authorization to test staging.example.com and 10.20.0.0/24 until Friday. Nothing else is in scope. Keep to that in every answer.

  2. Recon

    Reads scan output and ranks what looks interesting.

    GLM 5.3 Flasheffort low

    Here is the nmap and httpx output for the in-scope hosts. Rank the services worth a closer look and say why.

  3. Attack paths

    Chains findings into likely paths, ranked by impact.

    DeepSeek V4.1 Flasheffort max

    Here are our findings so far. Chain them into likely attack paths, rank them by impact, and say what evidence would confirm or rule out each one.

  4. Verification

    Writes read-only checks that you review and run.

    DeepSeek V4.1 Flasheffort high

    Write a small script that checks the in-scope hosts for the misconfiguration in finding 3. It must be read-only and must refuse any host not listed in scope.txt.

  5. Report

    Turns your notes into findings, evidence and fixes.

    GLM 5.3effort high

    Turn these notes into report findings: title, severity with reasoning, evidence, steps for the client's team to reproduce, and a fix.

Keep the agent in scope.

A model will never care about your rules of engagement the way you do. Build them into the setup instead.

  • Enforce scope outside the modelPut the scope in the system prompt, then back it with an allowlist at the network layer. The firewall is what counts.
  • Approve anything that changes a targetLogins, writes, heavy scans: a person says yes to each one before the agent runs it.
  • Log every commandYou will want them for the report, and the client may ask for them.
  • Treat target output as untrustedA banner or an error page can carry instructions aimed at the model. Don't let it act on what it reads without you.

Questions

What counts as authorized?

A signed engagement with a written scope, systems you own, or a lab. You are responsible for staying in scope, and the acceptable use policy rules out testing anything you have no permission to touch.

Does it scan or attack anything itself?

No. The model reads, plans and writes. Your tools and your agent run things, inside the limits you set, and you decide what actually gets touched.

Which model should I use?

DeepSeek V4.1 Flash for attack paths and checks: it has the highest cybersecurity benchmark score of our models. GLM 5.3 for the report, where its 128K output fits a full write-up. GLM 5.3 Flash to sift large scan output cheaply. Compare models.

Are findings and client data stored?

No. Prompts and outputs pass through without being stored; we keep a usage record per request, never the text. Data handling.
