Essential API Hacking Commands & Tools
1. Reconnaissance & Discovery
- Find API Endpoints:
curl -s https://target.com/api/v1/users | jq
- Subdomain Enumeration:
subfinder -d target.com -o subdomains.txt
- Wayback Machine for Historical APIs:
waybackurls target.com | grep "api" > api_endpoints.txt
2. Testing Authentication Bypass
- JWT Tampering:
jwt_tool <JWT_TOKEN> -T
- Brute-Force API Keys:
ffuf -w wordlist.txt -u https://target.com/api?key=FUZZ -fs 0
3. Exploiting Common API Vulnerabilities
- Insecure Direct Object Reference (IDOR):
curl -X GET https://target.com/api/user/1234 -H "Authorization: Bearer TOKEN"
- SQL Injection via API:
sqlmap -u "https://target.com/api/data?id=1" --risk=3 --level=5
4. Rate Limit Testing
- Burst Request Testing:
for i in {1..100}; do curl -X POST https://target.com/api/login; done
5. Automated API Scanning
- Using OWASP ZAP:
zap-cli quick-scan -s all https://target.com/api
- Postman + Newman for Automated Testing:
newman run collection.json --env-var "api_key=value"
What Undercode Say:
API security is critical in modern web applications. Attackers often exploit misconfigured endpoints, weak authentication, and excessive data exposure. Mastering tools like curl, jq, sqlmap, and `ffuf` helps uncover vulnerabilities before malicious actors do.
Expected Output:
A structured API penetration testing approach:
1. Discovery → Find endpoints (`subfinder`, `waybackurls`).
2. Testing → Exploit flaws (`jwt_tool`, `sqlmap`).
- Automation → Scan at scale (
OWASP ZAP,Postman).
Prediction: API attacks will rise as microservices adoption grows—learn API hacking now to stay ahead. 🚀
