Pentestfor APIs
Security assessments for REST, GraphQL, SOAP and microservice APIs, focused on authentication, authorization, data exposure and business logic flaws.
Assessment Coverage
An approach focused on real impact
APIs concentrate authentication, authorization and access to critical data. Our approach prioritizes hands-on exploitation and manual validation.
Manual Analysis
Focused on real vulnerabilities and business logic.
API Specialization
Experience with modern APIs and distributed architectures.
Complete Assessment
Authentication, authorization and data exposure.
Technical Reports
Clear documentation for both technical and executive audiences.
Most common risks found in APIs
APIs expose critical application functionality. Small flaws can lead to unauthorized access, abusive automation or mass data exposure.
Broken Object Level Authorization
Authorization flaws that allow unauthorized access to other users' resources and data.
A recurring problem in APIs without proper ownership validation.
Broken Authentication
Issues related to authentication, token management and sessions.
Includes JWT flaws, improper expiration and authentication bypass.
Sensitive Data Exposure
Improper exposure of sensitive data through API responses.
Internal data, personal information and entire objects exposed unnecessarily.
Missing Rate Limiting
No protection against abusive automation and mass enumeration.
Enables brute force, scraping and automated abuse.
Business Logic Flaws
Business logic flaws that can be exploited manually.
Issues that automated scanners typically miss.
Security Misconfiguration
Insecure settings related to CORS, headers and debug modes.
Insecure headers, verbose errors and exposed endpoints.
Assessment methodology
The assessment combines technical mapping, manual validation and controlled exploitation to identify real risks in your environment.
1. Discovery & Mapping
Complete mapping of the API's endpoints and flows.
- Manual route discovery
- Swagger/OpenAPI review
- Authentication identification
2. Authentication Testing
Validation of authentication and session mechanisms.
- JWT analysis
- Token manipulation
- Session handling
3. Authorization Testing
Verification of horizontal and vertical access controls.
- BOLA/BFLA
- Privilege escalation
- Access control validation
4. Manual Exploitation
Hands-on exploitation to validate real-world impact.
- Business logic abuse
- Mass assignment
- Sensitive data exposure
5. Reporting
Executive and technical report with practical recommendations.
- Detailed evidence
- Impact analysis
- Remediation plan
