APIs (Application Programming Interfaces) are the backbone of modern applications, enabling seamless communication between different systems. However, poorly secured APIs are a prime target for cybercriminals, leading to data breaches, unauthorized access, and business disruptions. At CyberHQ, we offer comprehensive API Penetration Testing (API PT) services to identify vulnerabilities, mitigate risks, and enhance the security of your APIs.

Why API Security Matters?

APIs expose critical business functions and sensitive data to external users and third-party services. A single vulnerability can lead to:

  • Data leaks affecting customer and business information
  • Unauthorized access allowing attackers to manipulate business processes
  • Broken authentication & session management leading to account takeovers
  • Injection attacks compromising backend systems
  • Denial of Service (DoS) attacks causing application downtime

Our API Penetration Testing Approach

CyberHQ follows a structured methodology aligned with OWASP API Security Top 10 and industry best practices. Our process includes:

1. Reconnaissance & Enumeration

  • Identifying exposed API endpoints
  • Gathering publicly available documentation
  • Understanding authentication & access control mechanisms

2. Authentication & Authorization Testing

  • Checking for weak or broken authentication
  • Identifying flaws in role-based access control (RBAC)
  • Testing OAuth, JWT, API keys, and session management

3. Input Validation & Injection Attacks

  • SQL, NoSQL, and command injection testing
  • XSS (Cross-Site Scripting) and CSRF (Cross-Site Request Forgery) tests
  • Parameter tampering and data manipulation attacks

4. Business Logic & Rate-Limiting Tests

  • Identifying workflow manipulation vulnerabilities
  • Testing for improper rate limiting and API abuse

5. Security Misconfigurations & Sensitive Data Exposure

  • Checking for improper CORS configurations
  • Testing error handling and verbose error messages
  • Identifying exposed debug endpoints and logs

6. Reporting & Remediation Guidance

  • Detailed vulnerability report with risk ratings
  • Proof-of-Concept (PoC) exploitation for critical findings
  • Actionable remediation steps and security best practices
