Introduction

Artificial Intelligence (AI) and Large Language Models (LLMs) are revolutionizing cybersecurity, enabling offensive, defensive, and hybrid (purple) security teams to automate tasks, enhance threat detection, and streamline workflows. The Red Blue Purple AI course by Jason Haddix and Arcanum Information Security explores cutting-edge AI applications in penetration testing, incident response, and threat modeling. This article breaks down key technical concepts, commands, and methodologies from the course.

Learning Objectives

  • Understand how LLMs enhance offensive (Red), defensive (Blue), and hybrid (Purple) security operations.
  • Learn practical AI-assisted techniques for recon, vulnerability analysis, and automation.
  • Explore best practices for AI-driven security tooling, including Burp Suite, Ghidra, and SOC bots.

1. AI-Powered Recon & OSINT Automation

Command: Subdomain Enumeration with AI-Assisted Tools

python3 ai_recon.py --target example.com --engine gpt-4 --output subdomains.txt

Step-by-Step Guide:

1. Install Dependencies:

pip install openai requests python-dotenv

2. Configure API Key: Store your OpenAI API key in .env: 

OPENAI_API_KEY=your_api_key_here

3. Run Script: The AI generates subdomains based on historical patterns and DNS data.

Use Case: Automates tedious OSINT tasks, reducing manual effort in bug bounty programs.

2. AI-Assisted Vulnerability Exploitation

Command: LLM-Assisted SQLi Payload Generation

from openai import OpenAI 
client = OpenAI()

response = client.chat.completions.create( 
model="gpt-4", 
messages=[ 
{"role": "system", "content": "Generate an advanced SQL injection bypass payload."}, 
] 
) 
print(response.choices[bash].message.content)

Step-by-Step Guide:

  1. Input Context: The LLM generates evasion payloads for WAF bypass.
  2. Test Payload: Use in tools like Burp Suite or SQLmap: 
    sqlmap -u "https://example.com/login" --data="user=admin&pass=" --tamper=ai_payload.py

Use Case: Enhances penetration testing by automating exploit refinement.

3. Blue Team: AI-Driven SOC Automation

Command: Suricata Rule Generation with LLMs

curl -X POST https://api.openai.com/v1/chat/completions \ 
-H "Authorization: Bearer $OPENAI_API_KEY" \ 
-H "Content-Type: application/json" \ 
-d '{"model": "gpt-4", "messages": [{"role": "user", "content": "Generate a Suricata rule to detect Cobalt Strike beacons."}]}'

Step-by-Step Guide:

  1. Feed Threat Intel: Provide IOCs (IPs, hashes) to the LLM.

2. Deploy Rule: Add output to `/etc/suricata/rules/local.rules`.

3. Reload Suricata:

suricatasc -c reload-rules

Use Case: Accelerates detection rule creation for emerging threats.

4. Purple Team: AI-Enhanced Threat Modeling

Command: MITRE ATT&CK Mapping with LLMs

import mitreattack.attack_api as attack_api 
import openai

techniques = attack_api.get_techniques() 
response = openai.ChatCompletion.create( 
model="gpt-4", 
messages=[{"role": "user", "content": f"Map 'Phishing with AI' to MITRE ATT&CK: {techniques}"}] 
)

Step-by-Step Guide:

1. Install MITRE ATT&CK SDK:

pip install mitreattack-python

2. Run Script: LLM maps adversarial tactics to framework IDs (e.g., T1566).

Use Case: Streamlines threat intelligence reporting.

5. Reverse Engineering with AI Assistants

Command: Ghidra Script Generation

// "Write a Ghidra script to find XOR decryption routines." 
// LLM Output: 
import ghidra.app.script.GhidraScript; 
public class FindXOR extends GhidraScript { 
public void run() throws Exception { 
// Script logic here 
} 
}

Step-by-Step Guide:

  1. Load Script: Save as `FindXOR.java` in Ghidra’s scripts folder.

2. Execute: Run via Ghidra’s script manager.

Use Case: Speeds up malware analysis.

What Undercode Say

  • Key Takeaway 1: AI is a force multiplier, but human oversight remains critical to avoid false positives/negatives.
  • Key Takeaway 2: Local LLMs (e.g., Llama 3, Ollama) reduce privacy risks when handling sensitive data.

Analysis:

The integration of AI into cybersecurity workflows is inevitable, but practitioners must balance automation with ethical considerations. Over-reliance on LLMs may introduce blind spots, especially in adversarial scenarios where attackers also leverage AI. Future developments will likely focus on self-improving AI agents capable of real-time threat adaptation.

Prediction

By 2026, AI-driven security tools will dominate 60% of enterprise SOCs, with LLMs automating 40% of repetitive tasks like log analysis and phishing detection. However, this will also lead to an arms race between AI-augmented attackers and defenders.
