Vehicle Telematics Platform — Security Audit

A comprehensive security audit of a vehicle telematics platform used by taxi services, law enforcement, and emergency medical services within a regional transportation network. The engagement covered infrastructure review, API endpoint analysis, communication layer inspection, and vulnerability assessment — resulting in the discovery of a critical data exposure vulnerability affecting all organizations on the platform.

The Challenge

A regional vehicle telematics provider needed an independent security assessment of their platform, which tracked real-time GPS locations, vehicle diagnostics, and driver information for taxis, police cars, and ambulances. The platform had grown organically without a formal security review, raising concerns about data protection across multiple client organizations.

Our Approach

We conducted a systematic audit covering infrastructure mapping, API endpoint enumeration, authentication and authorization testing, and communication protocol analysis. Our team identified a critical broken access control vulnerability that allowed any authenticated user to access data from any organization on the platform — including live and historical GPS coordinates, vehicle engine status, speed data, and driver license information for taxis, police vehicles, and ambulances. We delivered a detailed report with severity classifications, proof-of-concept demonstrations, and prioritized remediation steps.
