• "testing api security with owasp top 10"

• "Systematically assessing REST and GraphQL API endpoints against the OWASP API Se"

• During authorized API penetration testing engagements

• When assessing REST, GraphQL, or gRPC APIs for security vulnerabilities

• Before deploying new API endpoints to production environments

• When reviewing API security posture against the OWASP API Security Top 10 (2023)

• For validating API gateway security controls and rate limiting effectiveness

When NOT to Use

• When you lack proper authorization for testing
• For production systems without change management
• When the task requires legal or compliance expertise beyond technical scope

Prerequisites

• Authorization: Written scope document covering all API endpoints to be tested
• Burp Suite Professional: For intercepting and modifying API requests
• Postman: For organizing and executing API test collections
• ffuf: For API endpoint and parameter fuzzing
• curl/httpie: Command-line HTTP clients for manual testing

Workflow

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: ) -> :
     {k: re.findall(v, text)  k, v  IOC_PATTERNS.items()}
