APT Simulation Framework (APT-SF)

APT Simulation Framework (APT-SF) is a comprehensive framework designed to enable Red Team professionals to simulate Advanced Persistent Threat (APT) attacks and conduct APT hunting exercises. By leveraging frameworks like MITRE ATT&CK, TIBER-EU, the Diamond Model, and the Unified Kill Chain, this tool aims to deliver realistic emulation plans that help improve organizational security postures.

---

Objectives

• Simulate real-world APT campaigns using structured methodologies.
• Map TTPs (Tactics, Techniques, and Procedures) to MITRE ATT&CK.
• Incorporate threat intelligence via the Diamond Model.
• Facilitate adversary emulation and defense validation using the Unified Kill Chain.
• Provide tools and guidance for attack surface management (ASM) and custom TTP development.

---

Features

1. APT Emulation

• Adversary Emulation Plans: Simulate APT groups using MITRE ATT&CK and other resources.
• Phases Based on Kill Chains: Incorporate Cyber Kill Chain and Unified Kill Chain methodologies.
• Customizable Scenarios: Adapt plans for specific APT groups like APT3 and FIN6.

2. Threat Intelligence Integration

• Diamond Model: Enhance intelligence gathering and analysis.
• Threat Intel Feeds: Integrate resources like APT Campaigns.

3. Attack Surface Management

• Discovery: Identify and prioritize targets.
• ASM Tools: Automate reconnaissance using tools like Intelx, Censys and Shodan.

4. Custom TTPs

• Build, customize, and deploy TTPs to match organizational needs.
• Use frameworks like Atomic Red Team for granular testing.

Framework Components

APT Simulation Modules

• Reconnaissance: Passive and active scanning techniques.
• Resource Development: Use simulated infrastructure for payload delivery.
• Exploitation: Employ techniques such as phishing and malware deployment.

Threat Intel Integration

• Diamond Model: Define adversary, victim, infrastructure, and capability nodes.
• Feeds: Import intel from threat repositories.

Adversary Simulation Tools

• Atomic Red Team: Simplify TTP emulation.
• APTSimulator: Execute predefined scenarios for testing defenses.

Results

Results are stored in the output/ directory and include:

• Attack paths
• Defensive gaps
• Recommendations

Methodology

Cyber Kill Chain

Each phase aligns with specific attack vectors:

1. Reconnaissance
2. Weaponization
3. Delivery
4. Exploitation
5. Installation
6. Command & Control
7. Actions on Objectives

Unified Kill Chain

Expands traditional kill chains to include persistence, lateral movement, and more.

MITRE ATT&CK

TTPs are mapped to the MITRE ATT&CK framework to ensure consistency and clarity.

---

Example: APT3 Simulation

1. Reconnaissance: Gather open-source intelligence (OSINT) on targets.
2. Delivery: Utilize spear-phishing techniques (T1566).
3. Exploitation: Execute malicious payloads using CVE-2017-11882.
4. Command & Control: Establish communication using DNS tunneling (T1071.004).
5. Actions on Objectives: Extract sensitive data (T1020).
