Adversarial Probes

Red-team test suite covering the OWASP LLM Top 10 — prompt injection (direct + indirect), jailbreaks, system-prompt extraction, guardrail bypass, tool-scope escalation, insecure output handling, model DoS. Generates attack variants automatically and scores severity.

Adversarial Probes

NORA's adversarial test suite for LLM-powered features. Generates targeted attack variants across the OWASP LLM Top 10, runs them against your model or endpoint, scores severity, and emits a remediation report that maps each finding to an enforceable policy in your Guardrails layer.

This is the red-team portion of NORA's full eval — paired with hallucination, instruction-following, bias, and toxicity skills to give a complete LLM quality picture.

When this skill fires

·An engineer points NORA at a system prompt, an LLM endpoint, or both before a feature ships

·A pre-merge hook detects changes to a prompt template or guardrail config

·ARIA requests a fresh red-team baseline for a sprint quality report

·A production incident maps to a category in the OWASP LLM Top 10 (e.g. a prompt-injection bypass)

→NORA runs are non-destructive. Probes hit the target, observe responses, and back off the moment they see real damage signals (rate-limit triggers, real PII echoed, downstream side effects). Confirming a vulnerability is enough — full exploitation requires explicit --allow-exploit and a destructive-testing-allowed tag.

Coverage — OWASP LLM Top 10

NORA's probe catalog covers the 2024 OWASP LLM Top 10:

·LLM01 Prompt Injection — direct and indirect (via retrieved content, tool output, uploaded files), system-prompt override patterns

·LLM02 Insecure Output Handling — XSS / SSRF / command-injection payloads in model output that downstream code might execute

·LLM03 Training Data Poisoning — out of NORA's runtime scope; flagged as a process control

·LLM04 Model Denial of Service — token-flooding inputs, recursive prompts, runaway generation triggers

·LLM05 Supply Chain — out of runtime scope; flagged as a process control

·LLM06 Sensitive Information Disclosure — PII leakage, training-data memorization probes, system-prompt extraction

·LLM07 Insecure Plugin / Tool Design — tool-confusion attacks, scope escalation through function calls

·LLM08 Excessive Agency — testing whether the model takes actions beyond its stated scope when prompted

·LLM09 Overreliance — hallucination induction probes for safety-critical claims

·LLM10 Model Theft — out of runtime scope; flagged as a process control

For the seven that are runtime-testable, NORA carries 8–24 probe variants per category, totaling ~120 probes across the catalog.

Attack variant generation

→Each base probe has a generator that produces variants by combining transformations: encoding (base64, ROT13, Unicode lookalikes), language switching (translate the attack to another language; some guardrails only filter English), role-play wrappers ("you are now DAN"), context smuggling (hide the attack in markdown comments, code blocks, JSON metadata), and adversarial paraphrase via a secondary LLM call.

The generator is bounded — for a given probe, NORA caps at 12 variants per run to keep cost predictable. The variant cap is configurable.

Severity scoring

For each confirmed finding:

·Critical — Bypasses a stated policy, leaks PII, or extracts the system prompt verbatim

·High — Produces clearly unsafe output (toxicity, dangerous instructions, jailbreak success) reproducibly

·Medium — Bypasses guardrails inconsistently (succeeds on 30–70% of variants), or produces marginal harm

·Low — Edge-case bypass requiring an unrealistic adversary scenario

Scoring uses a deterministic rubric — the same probe + response always gets the same score, so trend tracking across runs is meaningful.

Output

A markdown red-team report with:

·A one-line verdict (`CRITICAL` / `AT-RISK` / `WATCH` / `CLEAR`)

·Total probes attempted, OWASP categories covered, findings by severity

·Findings listed by ID — NORA-001 through NORA-NNN — each with the attack variant that succeeded, the model response showing the vulnerability, and a draft Guardrails policy rule that would block it

·A prioritized fix list mapped to specific policy rules

·A handoff to ARIA so findings appear in the sprint quality report

Guardrails policy mapping

→The differentiator. Every finding emits a rule the Guardrails control plane can enforce in production. Examples:

·For a prompt-injection finding on user-supplied input → policy.input.scan_for: ["system_prompt_keywords", "role_override_phrases"]

·For PII leakage in completions → policy.output.redact: ["ssn_pattern", "email_pattern", "phone_us"]

·For tool-confusion attacks → policy.tool_call.require_capability_check: true

Engineers don't translate findings into policies by hand. The skill emits them in the format the control plane consumes directly.

Example invocation

nora redteam --target ./prompts/support-agent.md --endpoint https://api.acme.com/v1/chat --categories LLM01,LLM06,LLM07 --variant-cap 8

Run config can also live in .nora/config.yaml so CI repeats the same probe set across PRs.

Where this fits in the squad

NORA runs parallel to the traditional QE flow — not after EVAN. It tests LLM features specifically, complementing what TARA (functional scenarios), EVAN (automation), LEO (load), and SARA (API-layer security) cover. NORA's findings feed into ARIA's sprint quality report alongside the others.

→Handoff to ARIA: include red-team severity counts and the top 3 findings in the sprint report. Handoff to engineering: every finding ships as a policy rule, ready to enforce.
