What is Empire Framework?

Empire is a post-exploitation and Command & Control (C2) framework designed for red teaming and penetration testing. It provides PowerShell- and Python-based agents, allowing stealthy execution of post-exploitation payloads without requiring direct disk interaction.

Empire is widely used for lateral movement, persistence, and privilege escalation, making it a crucial tool for adversary simulation and security research.

Advanced Empire Techniques

• Fileless Attacks – Execute payloads in memory to evade AV detection.
• Persistence Mechanisms – Registry modifications, scheduled tasks, and startup entries.
• Lateral Movement – Utilize Empire to pivot through a compromised network.
• Bypassing AMSI & Defender – Obfuscating scripts to evade modern defenses.

Red Teaming Best Practices with Empire

✔ Use encrypted communication channels for C2 traffic.
✔ Implement OpSec techniques to minimize exposure.
✔ Deploy custom payloads to avoid antivirus detection.
✔ Rotate infrastructure to evade threat hunting efforts.
