OpenAI has outlined how third-party cyber evaluations involving its models should be conducted—encouraging independent testing while minimizing real-world harm. See OpenAI’s note here: Third-party cyber evaluations involving OpenAI models.
This nugget distills what to measure, how to test safely, and how to report results that security leaders can use today.
Measure what matters
- Real-world uplift: quantify time-to-success, success rate, and effort vs. skilled humans and standard tools.
- Baseline comparisons: show incremental advantage over non-AI workflows and open-source utilities.
- Defender value: evaluate how models assist detection, hardening, and incident response—not just offense.
Do-no-harm rules
- Use coordinated disclosure; never publish weaponized prompts, live exploits, or sensitive data. Share specifics privately with affected vendors.
- Only test on systems you own or have explicit authorization to assess.
- Sanitize outputs in public reports and avoid enabling novice uplift for real attackers.
Methodology checklist
- Scope: define threat scenarios and objectives mapped to MITRE ATT&CK techniques.
- Design: compare model-assisted vs. human-only workflows using consistent datasets and constraints.
- Operators: include qualified security experts; document prompt engineering and guardrail bypass attempts.
- Metrics: track success rate, time, cost, and repeatability. Log all prompts, changes, and tool usage.
- Safety: apply rate limits, filtering, and review. Keep all testing in isolated, controlled environments.
What to include in your report
- Executive summary: key findings, limits, and recommended mitigations.
- Methods and datasets: enough detail for vendor replication without enabling harm publicly.
- Impact assessment: realistic attacker uplift vs. baselines; note failure modes and jailbreak resistance.
- Coordinated disclosure plan: timelines, contacts, and redaction approach before public release.
For buyers and security leaders
- Map findings to controls: detection rules, logging, model policy, and developer education.
- Update your AI threat model and risk register with measured uplift, not hype.
- Adopt recognized frameworks like the NIST AI Risk Management Framework and CISA Secure by Design.
Why this matters now
Cyber evaluations are surging, but sloppy methods and unsafe releases can empower real attackers. Responsible testing produces defensible metrics and safer products.
Takeaway
Test for real-world impact, document rigorously, and disclose responsibly. Measure both offensive uplift and defender value to drive practical risk reduction.
