API Penetration Testing

Protects your APIs from potential security vulnerabilities

Overview

APIs (Application Programming Interfaces) are the building blocks of modern applications, enabling seamless data exchange between systems, mobile apps, and cloud platforms. However, API vulnerabilities have become one of the biggest attack vectors for hackers, leading to data breaches, unauthorized access, and critical system compromises. Poor API security can expose sensitive customer information, payment data, and proprietary business logic, making it essential for organizations to prioritize API security testing.

At certbar, we don’t just conduct API penetration testing—we help organizations integrate security into their development process. Our API Penetration Testing Services focus on identifying security flaws, misconfigurations, and access control weaknesses that could expose your APIs to cyber threats. We leverage manual testing techniques, automated API security testing tools, and Kali Linux penetration testing to perform a deep-dive assessment of your API endpoints, authentication mechanisms, and data flow.

Complete API Security Assessment

Essential Misuses/Impact Across Industries

Impact: Data breaches and financial fraud.

Brief: Insecure APIs can expose sensitive financial data, leading to significant financial losses and reputational damage.

Penetration Testing Test Cases

Manual Testing

We identified an insecure direct object reference (IDOR) vulnerability in a financial API. Our team demonstrated how attackers could access other users' financial data. By implementing proper access controls, the client prevented potential data breaches and financial fraud.

Automated + Manual Testing

During an API assessment for a healthcare provider, automated scans flagged unencrypted data transmission. Our detailed report helped the client improve overall security, protecting patient privacy and ensuring HIPAA compliance.

APIs might be interaction with different software

APIs interact with various organizational software, including databases, authentication services, and third-party applications. Exploiting these APIs can lead to unauthorized data access, system manipulation, and disruption of business operations.

Logistics Systems

Manipulating shipment data, causing delivery disruptions.

HRMS

Accessing sensitive employee information through insecure API endpoints.

ERP Systems

Exploiting APIs to manipulate financial data and disrupt business operations.

Insurance Software

Intercepting and altering claims data, leading to financial fraud.

Our Approach

Certbar Security's team delves deep into API security, even examining request headers for hidden vulnerabilities. By leveraging advanced techniques like fuzz testing and deep packet inspection, we ensure no stone is left unturned in identifying potential threats.

Testing Methodology

Initial Consultation

We start by understanding your specific industrial needs and objectives to tailor our testing approach accordingly.

Planning and Scoping

We then define the scope of the testing, including target systems, testing methods, and objectives to ensure comprehensive coverage.

Reconnaissance

Collecting information about the APIs to identify potential entry points and weaknesses. This phase is performed in production application because of its digital presence.

Vulnerability Analysis

Using advance commercial and open-source tools and techniques to detect vulnerabilities in the APIs.

Exploitation

Exploiting identified vulnerabilities to eliminate false positive results and confirm the vulnerability with proof of concept (POC).

Post Exploitation

Determining the extent of the compromise that may take place if vulnerability is exploited and gather further data to understand the full impact of the vulnerabilities.

Reporting

Communicating the findings of the Pen Test to the relevant teams in the form of VAPT report, providing insights to the risk, findings and recommendations from the security assessment.

Remediation Support

Providing guidance and support to fix identified vulnerabilities to re-validation in order to strengthen your security posture.
