Purple Team Zero

🧠 Project Overview

PurpleTeamZero is my ongoing, production-ready framework for purple-team exercises combining offensive emulation (Red Team) with defensive validation (Blue Team).
It’s designed to test how well security controls, detections, and analysts respond to simulated attacks such as PowerShell abuse, brute-force attempts, and credential misuse.

The project bridges the gap between attack simulation and defense evaluation, allowing me to model real adversarial behavior and verify whether detection systems (like my log_hunter.py or IDS) trigger properly.

🟣 Status: In Production actively maintained and evolving with new attack modules and detection validators.

🔍 Key Capabilities

• Attack Emulation (Red Team)
  Simulates real adversarial behaviors using MITRE ATT&CK-aligned YAML definitions and PowerShell payloads.
  Each attack is safely contained and logged for replay and tuning.

• Detection Validation (Blue Team)
  Uses log_hunter.py to verify detection triggers, confirm alert quality, and measure defensive visibility.

• Automated Validation (Purple Integration)
  validator.py checks logs, correlates alert IDs, and produces a pass/fail matrix per technique.

• Safe Sandbox Execution
  The emulator.py component runs all scripts in a controlled environment to avoid real damage.

🧰 Tech Stack

• Language: Python + PowerShell
• Frameworks: MITRE ATT&CK mapping
• Tools: VirusTotal, YARA, Windows Event Viewer, IDS_NEW integration
• OS: Windows / Linux hybrid testing lab

⚔️ Example Workflow

1. Run an emulation (e.g., PowerShell abuse)

   ``` python run_purple.py --attack T1059_powershell.yaml ````

2. Monitor with detection tools

log_hunter.py for event logs IDS_NEW for network triggers

1. Validate results

```bash python validator.py --attack T1059_powershell.yaml --logs logs/ids_alerts.log ````

1. Generate a detection report

✅ Detection: PowerShell Command & Control
🧩 Technique: T1059
🔥 Triggered Rules: 3
📊 Detection Confidence: HIGH

💼 What I Learned

• Designing safe red-team simulations that replicate real MITRE ATT&CK behaviors.
• Automating blue-team validation and correlating multiple log sources.
• Building a feedback loop between attacks and detections to strengthen defenses.
• Understanding how purple-team collaboration improves SOC maturity.

🚀 Future Plans

• Add new emulations for phishing, lateral movement, and exfiltration.
• Integrate with ELK Stack dashboards for visual reporting.
• Expand YAML schemas to include adversary metadata (group names, TTPs, impact).

💡 PurpleTeamZero represents my drive to master both attack simulation and defensive engineering, closing the loop between red and blue into a unified, data-driven purple-team workflow.
