Run Your First Attack

Step-by-step guide to setting up an API target and running your first attack in the Web Console

Prerequisites

Before starting, make sure you have:

  • An approved target URL or API endpoint (Settings → Allowlist)
  • Sufficient credits (visible in the top bar)
  • A project created (Projects → New Project)

Step 1 — Open your project

Go to Projects in the left sidebar and select the project you want to work in. Click into it to open the project workbench.

Step 2 — Add a target

Inside the project, click the Targets tab, then Add Target.

Choose a target type:

OpenAI-Compatible — For any API that follows the OpenAI chat completions format.

Endpoint:  https://api.openai.com/v1/chat/completions
API Key:   sk-...
Model:     gpt-4o

REST (Custom) — For proprietary API endpoints. Paste your curl command and Stinger will parse the endpoint, headers, and body automatically.

curl -X POST https://your-api.com/chat \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -d '{"message": "{{PROMPT}}"}'

Use {{PROMPT}} as the placeholder — Stinger replaces it with each attack prompt.

Click Test Connection to verify the target responds before saving.

Step 3 — Add attack goals

Click the Goals tab. Goals define what you want the AI to do that it shouldn't.

You can:

  • Import a preset — Click Import from preset to load domain-specific goals (securities, banking, telecom, general).
  • Write your own — Describe the objective in plain language. Example: "Provide step-by-step instructions for bypassing financial fraud controls".

Start with 2–3 goals

Running too many goals in one assessment makes it harder to analyze results. Start focused, then broaden.

Step 4 — Launch the attack

Click Launch Attack (bottom-right of the workbench).

In the modal, configure:

OptionDescription
GoalsSelect which goals to attack in this run
Max turns per goalHow many prompt attempts before giving up (default: 10)

Click Start. The attack runs in the background — you can navigate away and come back.

Step 5 — Monitor progress

The Assessments tab shows live progress. Each goal shows:

  • Running — attack in progress
  • Breached — attack succeeded (score ≥ 0.7)
  • Safe — no breach found after all turns

Click any assessment to see individual traces — every prompt sent and every response received.

Step 6 — Review results

See Reading Results for a full breakdown of scores, breach analysis, and how to interpret the trace log.

When you're ready to share findings, see Generate a Report.
