Forensic analysis of Android-WLAN artefacts

WLAN artefacts provide valuable insights into known networks, locations and the use of an Android device. As part of an IT forensic investigation, they can help to reconstruct events and device configurations.

Saved WLAN profiles
SSIDs and BSSIDs
Well-known networks
WLAN configuration files
Authentication and security settings
Timestamps and usage information
Artifacts specific to the manufacturer and version
System-level configuration files and databases

TECHNICAL BACKGROUND

Technical Fundamentals

Android stores various details about wireless networks and how they are used.

Forensically relevant artefacts include, amongst others:

  • •Saved WLAN profiles
  • •SSIDs and BSSIDs
  • •Well-known networks
  • •WLAN configuration files
  • •Authentication and security settings
  • •Timestamps and usage information
  • •Artifacts specific to the manufacturer and version
  • •System-level configuration files and databases

The information available varies depending on the Android version, device manufacturer and security 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.

1
Following a suitable forensic data backup, WLAN configurations, system-related databases and other network artefacts are examined using recognised IT forensic tools and manual analysis. The results are correlated with timestamps, location data and other technical artefacts. All stages of the investigation are documented in a reproducible manner.
2
LanCologne produces expert reports for private individuals, as well as for companies and solicitors. Our reports have already been used in court proceedings. In some cases, we have been directly commissioned to produce IT forensic reports. Upon request, we can provide anonymised or redacted sample reports or extracts.

TYPICAL QUESTIONS

When is this analysis required?

  • ✔Which WLAN networks was the device connected to?
  • ✔Which networks have been saved?
  • ✔Is it possible to trace the times at which connections were made?
  • ✔What configuration data is available?
  • ✔How significant are the existing artefacts?

LIMITATIONS & CONCLUSION

What you should know

Not all WLAN events are stored permanently. System updates, resets or manufacturer-specific changes may affect the availability of individual artefacts. Assessments are based solely on objectively verifiable technical findings.

The analysis of WLAN artefacts complements numerous other data sources and can provide important insights into the use of an Android device. A robust IT forensic assessment always requires a comprehensive evaluation of all available artefacts.
