MOBILE FORENSICS
Forensic analysis of Android Bluetooth artefacts
Bluetooth connections leave various technical traces on Android devices. These can provide evidence of paired devices, connections and usage patterns, and are therefore a regular feature of mobile IT forensic investigations.
TECHNICAL BACKGROUND
Technical Fundamentals
Android stores information about Bluetooth devices and their usage in various system files and configuration areas.
Forensically relevant artefacts include, amongst others:
- •Paired Bluetooth devices
- •MAC addresses and device identifiers
- •Pairing information
- •Bluetooth profiles (e.g. A2DP, HFP, BLE)
- •Connection and usage information
- •Timestamps and metadata
- •System-level configuration files
- •Features specific to the manufacturer and version
The type and scope of the data depend on the version of Android, the manufacturer and the device configuration.
OUR APPROACH
This is how your examination will be carried out
A transparent process – from the initial enquiry to the handover of the report.
TYPICAL QUESTIONS
When is this analysis required?
- ✔Which Bluetooth devices were paired?
- ✔Is it possible to trace past connections?
- ✔Which MAC addresses have been stored?
- ✔Which profiles were used?
- ✔How significant are the existing artefacts?
LIMITATIONS & CONCLUSION
What you should know
Not all Bluetooth activity is logged permanently. Changes resulting from system updates, resets or manufacturer-specific adjustments may affect the available data.
Bluetooth artefacts can provide valuable insights into connected devices and their usage. To draw reliable conclusions, it is always necessary to carry out a comprehensive analysis of all available technical artefacts.
