Introduction:

The traditional approach to bug bounty reconnaissance—manually scouring the web for self-hosted programs—is time-consuming and inefficient. Modern security researchers are now leveraging Large Language Models (LLMs) like Kimi AI to automate target discovery, transforming hours of tedious work into minutes of precise, AI-driven intelligence gathering. This article dissects a proven AI-powered workflow that uncovered seven active, self-hosted bug bounty programs with monetary rewards in under ten minutes, providing a technical blueprint for integrating artificial intelligence into your offensive security arsenal.

Learning Objectives:

  • Master an AI prompt engineering technique to discover self-hosted vulnerability disclosure programs (VDPs) with monetary rewards.
  • Understand how to filter and validate bug bounty targets using AI-generated reconnaissance data.
  • Build a repeatable, AI-driven reconnaissance pipeline that integrates with manual validation and reporting workflows.

You Should Know:

  1. The AI Prompt Engineering Framework for Target Discovery

The foundation of this rapid reconnaissance lies in a precisely crafted prompt that directs the AI to perform deep, targeted research. The core prompt, as demonstrated in the Kimi AI workflow, instructs the model to find “Self hosted bug bounty programs” that are not listed on major platforms like HackerOne, Bugcrowd, Intigriti, or YesWeHack. The prompt further refines the search by requiring programs to mention monetary rewards and specify a response time frame (e.g., “3 days or 1 week”). This combination of negative filtering (excluding platforms) and positive requirements (rewards + response time) forces the AI to surface legitimate, self-hosted VDPs that are often overlooked by automated scanners.

Step-by-Step Guide:

  1. Access the AI Platform: Navigate to Kimi AI (or a similar LLM with search capabilities).
  2. Deploy the Copy and paste the following optimized prompt into the chat interface:
    > “We need to find Self hosted bug bounty programs. they should not be on any platforms like hackerone or bugcrowd or intigrity or yeswehack or any other, they should be self hosted with like Bug bounty program or responsible disclosure programs and Vulnerabilty disclosure program and more and the should mention monetory rewards and respons tile like 3 days or 1 week or any othre time frame to response so do a deepr research and give me the entire list of atleast 50 programs”
  3. Initiate the Search: Execute the prompt. The AI will begin a multi-layered search, using various queries and dorks to identify independent programs.
  4. Filter Results: Review the AI’s output. The model will compile a list, filtering out platform-based programs and highlighting those that explicitly state reward policies and response SLAs.
  5. Extract and Validate: Extract the list of domains and program URLs. Manually validate a subset to confirm the AI’s findings are accurate and the programs are active.

2. Validating Targets and Extracting Technical Details

Once the AI provides a list of potential targets, the next step is manual validation and deep-dive reconnaissance. This phase involves visiting each program’s security page, analyzing the scope, reward structure, and response SLAs, and then mapping out the attack surface.

Step-by-Step Guide:

  1. Visit the Program Page: For each identified URL, navigate to the security or vulnerability disclosure page.

2. Verify Key Attributes: Confirm that the program:

  • Is hosted on the company’s own domain (not a third-party platform).
  • Explicitly states monetary rewards (e.g., “bounty,” “reward,” “cash prize”).
  • Publishes a response time policy (e.g., “we aim to respond within 72 hours”).
  1. Analyze Scope: Identify the in-scope assets (domains, IP ranges, applications).
  2. Perform Light Recon: Use basic tools to gather intelligence on the target:

– Linux/Unix: whois <domain>, dig <domain>, `nmap -sV -p- ` for initial port scanning.
– Windows: nslookup <domain>, Test-1etConnection <target_ip> -Port <port>.
– Browser Extensions: Use tools like Wappalyzer to identify technologies in use.
5. Document Findings: Record the program’s URL, reward range, response time, scope, and any initial recon data in a structured format (e.g., spreadsheet or markdown table).

3. Building an Automated Reconnaissance Pipeline

For sustained success, the manual process must be augmented with automation. This section covers creating custom bash scripts to automate the initial reconnaissance phase on validated targets.

Step-by-Step Guide:

  1. Create a Target List: Save the validated target domains into a text file, e.g., targets.txt.
  2. Write a Bash Script: Create a script `recon.sh` to automate subdomain discovery and port scanning.
!/bin/bash
 recon.sh - Automated subdomain and port scan for bug bounty targets

TARGETS_FILE="targets.txt"
OUTPUT_DIR="recon_output"

mkdir -p $OUTPUT_DIR

while read -r domain; do
echo "[] Starting recon on $domain"
 Subdomain discovery using assetfinder (install via go)
assetfinder --subs-only $domain > $OUTPUT_DIR/${domain}_subdomains.txt

HTTP probing using httpx (install via go)
httpx -l $OUTPUT_DIR/${domain}_subdomains.txt -o $OUTPUT_DIR/${domain}_alive.txt

Nmap scan on top ports
nmap -sV -sC -p- -T4 $domain -oN $OUTPUT_DIR/${domain}_nmap.txt

echo "[+] Recon completed for $domain"
done < $TARGETS_FILE
  1. Execute the Script: Run chmod +x recon.sh && ./recon.sh.
  2. Analyze Output: Review the generated files for subdomains, live hosts, and open ports.
  3. Integrate with AI: Feed the reconnaissance data back into an LLM to generate custom payloads or attack vectors specific to the discovered technologies.

  4. API Security and Cloud Hardening in Self-Hosted Programs

Self-hosted programs often expose APIs and cloud infrastructure that are critical to the business. Identifying misconfigurations in these areas can lead to high-value findings. This section focuses on testing for common API security flaws and cloud misconfigurations.

Step-by-Step Guide:

  1. Enumerate API Endpoints: Use tools like `ffuf` to fuzz for API endpoints.

– Linux: ffuf -u https://target.com/FUZZ -w /path/to/api-wordlist.txt -fc 404.
– Windows (PowerShell): `Invoke-WebRequest -Uri “https://target.com/api”` (basic check).
2. Test for Broken Object Level Authorization (BOLA): Modify ID parameters in API requests (e.g., `/api/user/123` to /api/user/124) to check for unauthorized access.
3. Check for Excessive Data Exposure: Analyze API responses for sensitive data (PII, tokens, internal IPs) that should not be exposed.
4. Assess Cloud Security: Check for misconfigured S3 buckets or Azure Blob storage.
– Linux: `aws s3 ls s3://bucket-1ame –1o-sign-request` (for public buckets).
– Windows: Use `az storage blob list` (Azure CLI) to test for public containers.
5. Verify SSL/TLS Configuration: Use `sslyze` or `testssl.sh` to identify weak ciphers or expired certificates.

5. Vulnerability Exploitation and Mitigation Strategies

Once vulnerabilities are identified, understanding both exploitation and mitigation is crucial for a professional bug bounty report. This section covers a typical vulnerability chain and how to remediate it.

Step-by-Step Guide (Cross-Site Scripting – XSS):

  1. Identify Input Vectors: Locate user-controlled input fields (search bars, comment boxes, URL parameters).
  2. Inject a Test Payload: Enter `` into the input field.
  3. Observe the Result: If the alert box appears, the application is vulnerable to reflected XSS.
  4. Craft a Proof of Concept (PoC): Create a URL that executes the payload: https://target.com/search?q=<script>alert('XSS')</script>.

5. Report and Mitigation:

  • Exploitation: Steal cookies, session tokens, or perform actions on behalf of the user.
  • Mitigation: Implement output encoding (e.g., HTML entity encoding), use Content Security Policy (CSP) headers, and sanitize user input with a well-vetted library (e.g., OWASP ESAPI).

6. Integrating AI Workflows with Traditional Tooling

The true power of this approach lies in combining AI’s pattern recognition with traditional security tools. This section provides a workflow for integrating LLMs into your existing stack.

Step-by-Step Guide:

  1. Use AI for Log Analysis: Pipe application logs (e.g., Apache/Nginx access logs) into an LLM and ask it to identify suspicious patterns (e.g., SQL injection attempts, directory traversal).

– Example “Analyze these web server logs and highlight any requests that appear to be malicious or attempt to exploit vulnerabilities.”
2. AI-Assisted Code Review: Feed code snippets to an LLM for a preliminary security review, asking it to identify potential vulnerabilities (e.g., hardcoded credentials, insecure deserialization).
3. Generate Custom Payloads: Use AI to generate context-specific payloads based on the target’s technology stack (e.g., “Generate a Python reverse shell payload for a Linux server running Flask”).
4. Automate Reporting: Use AI to draft professional vulnerability reports from your technical notes, ensuring clarity and completeness.

What Undercode Say:

  • AI is a Force Multiplier: Leveraging LLMs like Kimi AI for reconnaissance is not about replacing human intuition but about augmenting it, allowing researchers to cover more ground in less time.
  • Prompt Engineering is a Core Skill: The quality of the AI’s output is directly proportional to the quality of the prompt. Precision in defining requirements (e.g., excluding platforms, requiring rewards) is critical for success.
  • Automation is Key: The transition from manual discovery to automated, AI-driven pipelines is inevitable. Security professionals who embrace this shift will have a significant competitive advantage.

The integration of AI into bug bounty hunting represents a paradigm shift. The workflow demonstrated—using a single, well-crafted prompt to discover dozens of self-hosted programs—is a testament to the power of combining human expertise with machine intelligence. However, AI is a tool, not a replacement. The researcher’s ability to validate findings, perform deep technical analysis, and articulate vulnerabilities in a professional manner remains paramount. The future of offensive security lies in this symbiotic relationship: AI handles the heavy lifting of data collection and pattern recognition, while the human focuses on critical thinking, exploitation, and strategic decision-making.

Prediction:

  • +1 The democratization of AI-powered reconnaissance tools will lower the barrier to entry for aspiring bug bounty hunters, leading to a surge in new talent and a more diverse security community.
  • +1 AI-driven automation will force companies to harden their self-hosted programs, as the volume and speed of discovered vulnerabilities will increase, ultimately improving overall internet security.
  • -1 As AI-powered reconnaissance becomes mainstream, the signal-to-1oise ratio in bug bounty programs may decrease, with platforms and programs receiving a flood of low-quality, AI-generated reports.
  • -1 Attackers will also adopt these AI techniques, leading to an arms race where defensive AI must evolve to counter AI-driven offensive reconnaissance and exploitation.
  • +1 The demand for professionals skilled in both cybersecurity and AI prompt engineering will skyrocket, creating new career pathways and specializations.
