The Critical Role of API Penetration Testing in Modern Apps

Why APIs are Prime Targets

APIs (Application Programming Interfaces) handle massive amounts of sensitive data between microservices, mobile apps, and partner platforms. Because they are designed for machine-to-machine communication, vulnerabilities here often lead to massive data exfiltration.

Common API Vulnerabilities (OWASP API Top 10)

• Broken Object Level Authorization (BOLA): Allowing User A to access User B's data by simply manipulating an ID in the request.
• Broken Authentication: Weak token generation or missing validation.
• Excessive Data Exposure: Sending all data to the client and relying on the frontend to filter what the user sees.

At DefendShield, our API Penetration Testing service dives deep into these logical flaws to ensure your backend is bulletproof.
