The Telegram Messenger is often used to exchange ideas and organize oneself on controversial topics. Many users feel safe there. But an insider reveals how easy it is to spy on news and personal data. For secret services this is possible with the simplest means.
Insider: You can find out a lot about Telegram users
This is not the first time that Telegram has been criticized for its lax approach to user privacy. The ARD political magazine “Kontraste” and t-online have now researched together and talked to an insider who is active in countless Telegram groups and describes how simply read out content and find out information about the users.
The insider on Twitter under the name @ datenliebe1 is known, says that secret services in particular have an easy game. So he did many Telegram groups in his database, the content of which he has been collecting for years. After all, users do not notice that the content they have posted is being copied. In the case of public groups, he doesn’t even have to be a member to access them. Telegram offers extensive interfaces for processing data.
One point that is particularly interesting is the enables clear identification of users. As soon as you find a cell phone number somewhere, and according to him, people are quite ready to recklessly share their numbers in groups, a unique code can be found on the basis of this. This code number can be used to find out in which groups the users are active.
With that you can create a complete profile and you just find out who is in groups that you might not want anyone to know. Only “secret chats” are secure, as end-to-end encryption is used there. If there is a data leak, the group is reduced so much that only the hard core remains.

In secret groups, forbidden content can be shared that can never be discovered because the members of course do not report it. Whoever uses Telegram should get the entire story at t-online read through. The insider also communicated with t-online via the secure messenger Threema.
