Abstract

Now, Ukraine does not have uniform methodological approaches to conducting forensic examinations and expert research in the area of extraction and analysis of multimedia data from mobile terminals, in particular the content of the mobile application / messenger Telegram. This leads to the use of different approaches, methods and algorithms in state specialized expert institutions, which in some cases contradict each other, necessitates the appointment of repeated forensic examinations. Telegram is a multi-platform cloud messenger (cloud messenger) with VoIP features for smartphones, tablets and PCs, which allows you to exchange text, voice and video messages, stickers and photos, files in many formats. You can also make video and audio calls, organize video conferences for groups and channels with many users. Telegram clients are available for Android, iOS, Windows Phone, Windows, macOS and GNU / Linux. In addition to exchanging messages in dialogs and groups, you can store an unlimited number of files in the messenger, maintain channels (microblogs), create and use bots. Telegram provides seamless synchronization and, as a result, the ability to access your messages simultaneously from multiple devices, including tablets and computers, as well as provide an unlimited number of photos, videos and files (doc, zip, mp3, etc.) up to 2 GB each . Telegram stores only the information necessary to function as a multifunctional cloud service. For example, cloud chats to access from any device without using third-party backups or your contacts. Telegram is used on several platforms with continuous synchronization. However, there may be cases where a message placed on one platform does not appear on another and appears without the end user’s knowledge. The possibility of such cases and their further study is considered in this article.
