Executing Red Team Exercise
When to Use
- Assessing an organization's ability to detect, respond to, and contain a realistic adversary operation
- Testing the effectiveness of the security operations center (SOC), incident response team, and threat hunting capabilities
- Validating security investments by simulating attacks that chain multiple vulnerabilities and techniques
- Evaluating the organization's security posture against specific threat actors (nation-state, ransomware groups, insider threats)
- Meeting regulatory requirements for adversary simulation (TIBER-EU, CBEST, AASE, iCAST)
Do not use without executive-level authorization and a detailed Rules of Engagement document, against systems where disruption could affect safety or critical operations, or as a replacement for basic vulnerability management (fix known vulnerabilities first).
Prerequisites
- Executive-level written authorization with clearly defined objectives, scope, and off-limits systems
- Red team command and control (C2) infrastructure: primary and backup C2 channels with domain fronting or redirectors
- Operator workstations with OPSEC-hardened toolsets (Cobalt Strike, Sliver, Brute Ratel, or Mythic)
- Threat intelligence on adversary groups relevant to the target organization for adversary emulation planning
- Trusted agent (white cell) within the target organization who manages the exercise boundaries without alerting defenders
- MITRE ATT&CK matrix for mapping planned and executed techniques

Workflow
Step 1: Adversary Emulation Planning
Develop the operation plan based on a realistic threat model:
- Threat actor selection: Select an adversary group relevant to the organization's industry. For financial services, emulate FIN7 or Lazarus Group. For healthcare, emulate APT41 or FIN12. Map the selected adversary's known TTPs from MITRE ATT&CK.
- Objective definition: Define measurable objectives such as "Access customer financial data from the core banking system" or "Demonstrate ability to deploy ransomware across the domain"
- Attack plan development: Create a step-by-step operation plan mapping each phase to ATT&CK tactics:
