Telegram Forensics – Forensic Analysis of Telegram Communications

Telegram is used worldwide for both personal and business purposes. Its features – including cloud-based chats, groups, channels and optional secret chats – give rise to specific requirements for IT forensic analysis. The aim is to objectively analyse existing digital traces, taking into account the technical circumstances and documented investigative methods.

TECHNICAL BACKGROUND

Technical Fundamentals

Telegram differs from many other messaging apps in its cloud architecture. Depending on the type of chat, device, operating system and app version, different data may be stored locally. The validity of an investigation therefore always depends on the specific data sources available. All results are assessed and documented within the overall technical context.

TYPICAL QUESTIONS

When is this analysis required?

  • ✔Which Telegram chats and media files are stored on the device?
  • ✔Which groups or channels were used?
  • ✔Is it possible to reconstruct the timeline of communication processes?
  • ✔Are there any indications of deletions or anomalies?
  • ✔What other device artefacts are included in the assessment?
