API Pentesting

An API (Application Programming Interface) is an interface that allows you to build on the data and functionalities of another application while providing tools, routines and protocols for developers building software applications and also enabling the user to extract and share data in an accessible manner. While the API provides you with an interface where you can enhance the functionalities of another application, it is the web service which is a network-based resource that actually fulfils the task. Hence an API can either be online or offline. However, the APIs that use web services as a resource to fulfil a specific task, are termed as Web service APIs.

APIs often self-document information regarding their implementation and internal structure, which is widely used as intelligence for cyber-attacks. Additionally, vulnerabilities such as weak authentication, lack of encryption, flaws in the business logic and insecure endpoints make APIs vulnerable to the attacks mentioned below.

• Injection Attacks
• Sensitive Data Exposure
• DoS Attack
• Broken Access Control
• Broken Authentication
• Parameter Tampering
• Man-In-The-Middle Attack (MITM)

Why REDSECLABS?

• Our testing methodology starts with understanding the flow of the application, its functionalities, critical components and then mapping what an attacker in the application can exploit.
• We carry out the testing manually using some of our custom developed scripts.
• We perform in-depth analysis of ‘data at rest’ as well as ‘data in transit’.
• Each application is vetted by our senior resource before we share it to our client.
• Once our testing is completed, we provide a report, which indicates vulnerabilities and associated risk rating, a solution to fix the vulnerability along with the evidence.
• We share the report only after testing the entire application, as the Vulnerabilities are interdependent.
• We avoid using tools because we think tool is a machine and hacker is a human brain.
