Forensic analysis of Android cloud synchronisation

Many Android devices automatically synchronise contacts, calendars, photos, app data and other information with cloud services. These synchronisation processes can generate forensically relevant artefacts that allow conclusions to be drawn about the data set and chronological sequences.

TECHNICAL BACKGROUND

Technical Fundamentals

Different cloud platforms are used depending on the manufacturer and the services employed.

Forensically relevant artefacts include, amongst others:

  • •Google Drive and Google One
  • •Google Account synchronisation
  • •Samsung Cloud, Xiaomi Cloud and other manufacturer services
  • •Synchronisation logs
  • •Account and device assignments
  • •Synchronisation points
  • •Metadata and configuration files
  • •App-specific cloud artefacts

Availability and scope depend on the Android version, the manufacturer and the relevant synchronisation settings.

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, synchronisation artefacts, account information, metadata and configuration files are analysed using recognised IT forensic tools as well as manual analysis. The results are correlated with local data, timestamps 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 cloud services were used?
  • ✔What data has been synchronised?
  • ✔When did the dubbing take place?
  • ✔Can any differences be identified between local and cloud data sets?
  • ✔How significant are the existing artefacts?

LIMITATIONS & CONCLUSION

What you should know

Cloud services do not store all information permanently. Deletions, synchronisation conflicts, account settings and access rights may affect the data available. Assessments are based solely on objectively verifiable technical artefacts.

The analysis of cloud synchronisation complements the examination of local Android data and enables a well-founded technical assessment of synchronisation processes. Reliable conclusions require a comprehensive evaluation of all available artefacts.

Frequently Asked Questions

Click on a question to see the answer.

Which cloud services are being examined?

These include, amongst others, Google Drive, Google One and manufacturer-specific cloud services, provided that the relevant artefacts are available.

Are synchronisation timings relevant?

Yes. They can be important for reconstructing chronological sequences.

Are conflicts between local and cloud data taken into account?

Yes. Where technically feasible, such differences are assessed.

Can the cloud replace local data?

No. Both data sources are considered within the overall technical context.

Could an expert report be drawn up on this matter?

Yes. The results are documented in a transparent manner and assessed from a technical perspective.
