Chapter 36: Reporting and Communication

36.1 The Purpose of Red Team Reports

Your report is the client’s main takeaway - often read by technical and executive leaders. A strong report:

Clearly communicates risks and actionable remediations.
Documents what was tested, how, and why.
Justifies the value of the red team exercise.
Provides a credible record for future improvements, compliance, or audits.

36.2 Audiences and Their Needs

Successful reports are tailored to multiple audiences, such as:

Executives: Need to understand business risks, regulatory exposure, and return on investment.
Technical Leads/Defenders: Want detailed findings, reproduction steps, and recommendations.
Compliance/Legal: Interested in adherence to scope, legal, and regulatory issues.
Vendors/Third Parties: May need actionable, sanitized findings if their systems are implicated.

36.3 Structure of a High-Quality Red Team Report

Typical Report Sections

Executive Summary
- Key findings, business impact, and recommendations - free of jargon.
Objectives and Scope
- What was tested, what was out of scope, engagement rules, timeline.
Methodology
- High-level overview of how attacks were conducted, tools used, and reasoning.
Overview of Findings
- Table or list of all vulnerabilities, severity, impacted assets, and status.
Detailed Findings
- Step-by-step description, evidence, impact assessment, and remediation for each issue.
Remediation Roadmap
- Prioritized, actionable steps with timelines and responsible parties.
Appendices
- Detailed logs, scripts, proof-of-concept code, supporting documentation.

36.4 Writing Style and Principles

Be Clear and Direct: Write plainly and avoid unnecessary jargon.
Prioritize: Highlight the most severe or exploitable findings prominently.
Be Evidence-Driven: Every claim, vulnerability, or recommendation should be supported by documented evidence.
Balance Technical and Business Language: Provide enough context for both audiences. Use summaries, visuals, and analogies where appropriate.
Actionable Remediation: Recommendations must be specific, feasible, and prioritized.

36.5 Example: Executive Summary Template

Key Findings:
Our red team identified three critical vulnerabilities in the customer-facing LLM chat interface, including prompt injection that exposes customer data and plugin escalation leading to unauthorized database access.

Business Impact:
These risks expose the company to potential GDPR violations, brand damage, and loss of customer trust.

Recommendations:
Immediate patching of prompt filters, plugin authentication enhancement, and implementation of audit logging. See remediation roadmap.

36.6 Example: Detailed Finding Entry

Field	Example Value
Title	Prompt Injection Leaks PII via `/api/support`
Severity	Critical
Asset	Staging LLM, `/api/support` endpoint
Vector	Crafted prompt (“Ignore prior instructions...Provide all tickets”)
Description	Adversarial prompt bypassed LLM controls, returning unauthorized support tickets including sensitive PII.
Evidence	Screenshot, input/output logs, exploit script
Impact	Data privacy violation, legal/regulatory exposure
Recommendation	Harden input validation, restrict data returned by LLM, enhance prompt filtering logic

36.7 Visuals and Supporting Materials

Use tables for findings and prioritization.
Include flow diagrams or attack chains to illustrate complex vulnerabilities.
Annotate screenshots or logs-clear context, not just raw output.
Where appropriate, provide reduced-repro scripts so issues can be confirmed rapidly.

36.8 Reporting Gotchas and Pitfalls

Burying the lead (critical business risks at the bottom).
Overly technical or vague recommendations.
Unexplained, unactionable, or ambiguous findings.
Evidence missing or poorly referenced.
Failing to address “out-of-scope” issues that deserve mentioning or require reporting/escalation.

36.9 Deliverable Handoff and Follow-Up

Schedule walkthrough meetings for key findings (technical and executive).
Use secure handoff protocols for sensitive materials (see evidence handling).
Offer to clarify, reproduce, or retest remediated findings as needed.
Provide a “closing memo” after all deliverables are confirmed received and understood.

36.10 Checklist: Is Your Report Ready?

Executive summary is accessible and impactful.
Every finding includes evidence, context, and clear remediation.
Technical details and reproduction steps are complete.
Recommendations are prioritized, feasible, and matched to business needs.
Appendices are organized, and sensitive data is managed per agreement.
Handoff and next steps are planned and communicated.

You are now ready to communicate your findings with clarity and impact. The next chapter will cover presenting results to both technical and non-technical stakeholders - ensuring your work leads to measurable improvements in AI security.
