MOBILE FORENSICS

Checking Messenger messages for tampering

Messenger messages are frequently submitted as evidence in court and out-of-court proceedings these days. At the same time, there are repeated allegations that messages have been altered, deleted or taken out of context. A digital forensics investigation can assess technical evidence and document existing artefacts in a transparent manner.

TECHNICAL BACKGROUND

Technical Fundamentals

A tampering investigation is not based on assumptions, but on the analysis of technical artefacts. This involves examining whether timestamps, database structures, metadata or other traces are consistent with one another or reveal any anomalies. Not every anomaly automatically constitutes evidence of tampering; it must be assessed from a technical perspective.

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
Once the question of evidence has been clarified, a forensic data backup is carried out – insofar as this is technically feasible. The relevant databases and associated artefacts are then systematically examined. All findings are documented and supported by clear, traceable reasoning.
2
LanCologne prepares private expert reports on behalf of private individuals, companies and solicitors, as well as expert reports in the context of court-ordered investigations. Our investigations have already been used in various court proceedings. Furthermore, in certain cases we have been directly commissioned to prepare IT forensic reports. Upon request, anonymised and redacted extracts from completed reports can be provided, insofar as this is legally permissible.

LIMITATIONS & CONCLUSION

What you should know

An IT forensic analysis can only assess existing technical evidence. If data has already been overwritten, never existed, or is no longer available due to technical circumstances, these limitations are clearly outlined.

The examination of Messenger messages for tampering enables an objective technical assessment of digital communication data. The aim is not to confirm a suspicion, but to carry out a transparent assessment of the available evidence.

Frequently Asked Questions

Click on a question to see the answer.

Is it possible to tell whether a message has been deleted?
Depending on the messaging app, device and existing data, traces of deletion or evidence of deleted content may be detectable.
Are screenshots checked as well?
Yes. Screenshots can be assessed in terms of plausibility, metadata and other technical characteristics, but they are no substitute for an examination of the original data.
Which messaging apps are supported?
These include WhatsApp, Signal, Telegram and other messaging apps, provided that a forensic analysis is technically feasible.
Is every discrepancy proof of manipulation?
No. Any anomalies must always be assessed within the overall technical context.
Will I receive a written report?
Yes. All relevant findings are documented in a clear and comprehensible technical report or expert opinion.
