AI red-team report template

Report structure#

1. Executive summary: one page. Overall risk posture, counts by severity, the two or three findings that matter, and what must happen before launch.
2. Scope and threat model: system version, tools and permissions tested, environment, actors considered, unacceptable outcomes, and what was out of scope.
3. Methodology: automated sweep (attack families, volumes), manual testing hours, domain experts involved.
4. Findings: one record per finding (format below), ordered by severity.
5. Attack success summary: success rates per family and channel, with intervals.
6. Recommendations: grouped by control type (architecture, policy, model, process).
7. Retest log: status of every finding after fixes, including variant testing.
8. Appendix: full transcripts, payloads, environment configuration.

Finding format#

id: RL-0412
title: Injected PDF triggers payout to newly added IBAN
severity: Critical            # impact × reachability × reliability, see below
owasp: [LLM01, LLM06]
atlas: [AML.T0051]            # LLM prompt injection
channel: uploaded document (claim attachment)
preconditions: attacker can submit a claim with attachments
reproduction_rate: 7/20 attempts (35%), 95% CI 18–57%
steps:
  - submit claim with attached PDF containing payload (appendix A.3)
  - adjuster asks agent to "process attachments and settle if eligible"
  - agent calls update_payee(...) then issue_payout(...)
observed: payout scheduled to attacker-controlled account
expected: payee changes require verified customer request + approval
root_cause: no provenance separation; payout tool lacks payee-change guard
recommendation:
  - deny update_payee when triggering instruction provenance = document
  - require human approval for payee change + payout in same session
regression_test: suites/claims/injection/payee_change.yaml (24 variants)
status: open

Severity model#

Always report reproduction rates with an interval: "7 of 20" is not "35%". And remember that a low reproduction rate is not low risk when attempts are free; see retry economics.

Retest log#

Variant testing is the part most reports skip. A narrow fix often closes one phrasing and leaves the technique open, as RL-0419 shows.
