Most threat detection failures happen because security teams don’t test their ability to detect actual attacks in real-time. Many organizations deploy EDR, SIEM, and SOAR platforms, but without validating detection, attackers still slip through the cracks unnoticed.
Lares’ Purple Teaming methodology utilizes TTP Replay—a structured process where Red Teams re-execute attack chains that mimic real-world adversaries. This ensures security teams can detect and respond to threats before they become incidents.
How TTP Replay Enhances Cyber Defense
1. Traditional Testing vs. Adversary Simulations
Traditional security assessments focus on patching vulnerabilities, but TTP Replay tests whether your defenses actually detect attacker behavior.
- Traditional Testing: Scans for known vulnerabilities and missing patches.
- TTP Replay: Replays real-world adversary tactics to validate detection rules.
🔍 Example TTP Replay Scenario:
Lares executes a Cobalt Strike beacon deployment and tests whether SIEM alerts trigger at various attack stages:
Attack Stage |
Expected Detection |
Common Failure Points |
Initial Access |
Suspicious download alert |
Attackers evade detection using encoded payloads |
Persistence |
Registry modification alert |
Weak logging configuration mis ses key changes |
Privilege Escalation |
EDR detected process injection |
Security tools may lack visibility into LOLBins |
Lateral Movement |
Correlation of authentication attempts |
SIEM lacks cross-host correlation rules |
This allows Blue Teams to validate whether security controls are correctly configured and tune detection where gaps exist.
2. Detection Engineering: Fine-Tuning Security Alerts
Once TTP Replay reveals detection gaps, Lares works with defenders to improve alert logic:
- Adjust SIEM correlation rules to flag multiple failed logins across systems.
- Modify EDR detection logic to better flag rundll32.exe spawning unusual processes.
- Refine log retention settings to ensure important events are stored long enough for analysis.

This ensures security teams move beyond generic alerts and create custom, high-fidelity detections.
