Forensic analysis of eSIM and mobile communications module data – utilising built-in mobile connections for forensic purposes

Many modern vehicles are fitted with a permanently installed mobile communications module with its own eSIM, which is used to provide telematics, emergency call and communications services. Connection and usage data may be generated both within the vehicle and by the mobile network operator.

Enquire without obligation

This data may be relevant for forensically reconstructing a vehicle’s communication connection at a specific point in time, as well as the location of the relevant mobile phone cell connection.

Why LanCologne?

Since its foundation, LanCologne has specialised in professional IT forensics. Our staff have decades of experience in the field of information technology and assist companies, solicitors, private individuals and, on a regular basis, the courts in the technical investigation of complex digital matters.

The examination is, as a matter of principle, carried out exclusively on a forensic copy, a forensic image or a data source captured in a technically equivalent manner that preserves the integrity of the evidence. The original evidence remains unchanged and is stored in a manner that preserves its integrity.

Our services

We analyse the available data from the vehicle’s mobile communications module and, subject to the appropriate authorisation, use supplementary connection data from the mobile network operator for cross-checking purposes.

Typical areas of application

•Evidence of an active mobile network connection for the vehicle
•Supplementing location and movement data analyses using mobile phone cell data
•Clarification of communication processes via the vehicle module
•Investigation of cyber security incidents relating to mobile communications
•Judicial and non-judicial expert reports
•Collaboration with mobile network operators

This is how an eSIM/mobile communications module analysis is carried out

Once the vehicle has been secured, the available connection data from the mobile communications module is extracted and, provided the necessary authorisation is in place, cross-referenced with the provider’s data.

Why is the analysis of eSIMs and mobile radio modules relevant in a forensic context?

Cell-based location data may still be available even when other on-board location sources are unavailable.

This data source may also be relevant for investigating cyber security incidents relating to vehicle communications.

Frequently Asked Questions

Does every modern vehicle have its own mobile communications module?+
Not necessarily; it depends very much on the manufacturer, model and specifications.
How is data from the mobile network operator accessed?+
Only with the appropriate authorisation or on the basis of a valid legal basis.
Is the accuracy of location determination using mobile phone cell data comparable to that of GPS?+
No, mobile phone cell data generally provides a much rougher estimate of location than satellite-based positioning.
