Regular API penetration testing is a fundamental part of meeting your organisation’s cybersecurity and compliance goals
Regular API penetration testing ensures that weaknesses in your APIs are identified so they can be addressed, protecting against cyber-attack
Regular API penetration testing provides assurance to stakeholders that your system APIs are secure
Blackfoot’s API penetration testing service makes finding and fixing security weaknesses in APIs simple, no matter how complex your APIs may be.
API penetration testing is a critical part of the software development process that focuses on assessing the functionality, reliability and security of application programming interfaces (APIs).
By systematically testing API endpoints, data communication, error handling and authentication mechanisms, potential issues can be identified early on, ensuring the seamless integration and interaction between different software components.
API testing helps validate the data flow, performance and compliance of APIs, ensuring they meet industry standards and provide a robust foundation for application development and integration.
Blackfoot’s manual penetration testing, or exploit testing, builds on vulnerability assessment results to simulating real-world attack methods.
Unlike automated vulnerability scanning, our manual penetration testing is delivered by our highly skilled testers who actively seek to progress vulnerabilities through the cyber kill-chain. They will assess the security of your APIs by employing a combination of tools, techniques and, most importantly, creativity. As a CREST-certified organisation, Blackfoot penetration tests follow an approved, structured methodology.
Our expert testers first establish a deep understanding of the API, its operation and configuration, and the associated operator roles and access permissions.
Our testers will then seek to discover any potentially exploitable vulnerabilities in the application, before testing their exploitability. They’ll also validate whether successful exploitation exposes other areas or provides potential threat routes to other business systems.
Based on clearly defined test objectives, this involves exploring compromised systems to determine whether they host sensitive files or information, allow privilege escalation or permit access to password information which could be used to compromise other systems or internal applications.
Blackfoot reports its findings along with clear recommendations for prioritised remediation activities.
Q: What is API penetration testing?
A: API penetration testing is a security assessment focused specifically on the application programming interfaces that underpin modern web and mobile applications. APIs often expose significant functionality and data that are not visible through a standard user interface, and they can introduce vulnerabilities that differ from those found in traditional web applications. Testing covers authentication, authorisation, data exposure, rate limiting, injection flaws and API-specific attack patterns such as those documented in the OWASP API Security Top 10.
Q: Why are APIs a significant security risk?
A: APIs frequently handle sensitive data and provide programmatic access to core business functions. Because they are designed for machine-to-machine communication rather than human interaction, they can be overlooked in security testing programmes that focus primarily on user-facing interfaces. Attackers increasingly target APIs because they can provide direct access to underlying data or functionality with fewer of the controls that protect user interfaces. Dedicated API penetration testing addresses this risk directly.
Q: What documentation do we need to provide for API penetration testing?
A: To conduct thorough API testing, Blackfoot typically requests API documentation such as an OpenAPI or Swagger specification, along with test credentials and, where relevant, information about the intended use cases and data flows. Where documentation is limited or unavailable, our testers can use discovery techniques to map the API surface before testing begins. The more context you can provide, the more efficient and comprehensive the assessment will be.
