An adversarial attack simulation engagement delivers an attack narrative: an account of how a realistic attacker moved through your environment, which Key Assets they reached, and what to fix first. A red team engagement is adversarial attack simulation: the team mirrors the tactics, techniques, and procedures (TTPs) of a specific real-world threat actor. Once you have chosen that path, here is what to expect and settle first.
How Adversarial Attack Simulation Deliverables Differ
An adversarial attack simulation report is organized around the objective, while a penetration test report is organized around findings. A strong pentest report carries an attack narrative too, but its core is a prioritized list of vulnerabilities with remediation steps inside a defined scope. A strong simulation report reconstructs the whole chain: how the team gained access, each technique used along the way mapped to MITRE ATT&CK, and whether the team reached the objective set at kickoff.
Teams that expect a vulnerability list and receive an attack narrative, or the reverse, end up reading the wrong document. Your infrastructure team reads a pentest report to prioritize patching. Your CISO or VP of IT reads an adversarial attack simulation report to see which combination of weaknesses got past your cyber security controls, then carries that story into the budget conversation. Ask the vendor for an executive summary written for that second reader, and for a remediation roadmap sequenced by how much each fix breaks the attack chain.
Designing a Scenario from What's Already Known
A scenario can draw on what your organization already knows about its own weaknesses. Open findings from earlier tests, accepted-risk items, and attack paths verified in prior engagements give the team a realistic starting point. Your Key Assets, the data and systems being protected, set the objective.
MITRE ATT&CK supplies the second input. The framework catalogs how real threat actors operate, tactic by tactic, so a scenario can follow documented behavior, such as credential access followed by lateral movement.
The Global Ghost Team™ spends much of an engagement in a pre-attack phase, gathering open-source intelligence so the scenario reflects what an outsider can learn about you. The team then splits into small groups by target, such as internal networks and web applications, and agrees on a joint plan before executing together. Bring your open findings and Key Assets list to the scoping call; they shape the scenario.
How Rules of Engagement Differ
Rules of engagement for an adversarial attack simulation cover everything a penetration test's rules do, plus the terms that make a realistic attack safe to run. A pentest's rules define scope, how findings get validated, safety around production systems, and the evidence needed to track remediation. Simulation rules also need the objective, permitted and prohibited techniques, whether the exercise runs covertly or your security team knows about it, escalation contacts, and stop conditions.
Settle these at kickoff. At Mitnick Security, kickoff is where you agree on scope, goals, and how much disruption is acceptable. During the engagement, your team can reach a dedicated channel 24/7 to confirm whether suspicious activity belongs to the testers or a real attacker, and the team notifies you immediately about critical vulnerabilities. Like a real attacker, the team does not announce a breach as it happens. Ask any adversarial attack simulation services vendor to walk through each item before you finalize scope.
Frequently Asked Questions
Two questions shape a scoping call: what the report includes and who knows about the exercise.
What does an adversarial attack simulation report include?
A strong report includes an executive summary, the attack narrative from first access to objective, techniques mapped to MITRE ATT&CK with evidence, and remediation guidance that rates each finding from informational to critical.
Who should know an adversarial attack simulation is happening?
That decision belongs in the rules of engagement. Some organizations keep the security team unaware to test how it responds to a live attack, and others brief it in advance.

Next Steps
The next step is a scoping conversation about objectives, rules of engagement, and what the report needs to show your CISO or VP of IT. Across penetration testing and red team operations, The Global Ghost Team has a 100 percent successful track record penetrating the systems clients pay it to test.
