A friend told this story. One person leaked to his girlfriend all the messages that this same friend had ever sent anywhere via WhatsApp. And the message was leaked by a person related to the special services, and let's just say, he claimed to be a girl. Simply put, he wanted her to be with him. In the leaked information, the girl saw that the friend (who told the story) was texting and dating other girls. But that's not the point. The bottom line is that messages sent via WhatsApp were brazenly leaked, and the application does not protect the user in any way. The Telegram messenger positions itself as safe and crypto-protected. However, there are people who say that Telegram's security is a lie. Is Telegram safe in your opinion in terms of protecting transmitted information and are there any messengers that ensure the security of information.

Jabber is a secure protocol. Clients under it the sea.
But something tells me that in your story, the compromise of correspondence did not occur as a result of passive listening or an active MitM attack on the WatsApp protocol. The human factor is many times more likely. In addition, most impressive stories that feature "a person related to the secret services" are intended to impress impressionable people. Of course, I don’t know the details of the situation with your friend, but the first thing that comes to mind is the most elementary option - that girl ended up in the hands of his phone only once, just for half a minute, or the phone ended up in the hands of one of his friends, who his kindness could not refuse this girl. I'm not saying anything, but in most of these cases, a banal human factor is most often hidden behind a grandiose "break-in".

While a friend was taking a shower, Madame sent all the WhatsApp correspondence to her mail, using such a function of the WhatsApp itself.
Regular chats in telegrams are also encrypted "client1-server_telegram-client2". Telegram secret chats - "client1-client2" encryption. An alternative to secret chats in telegram is the Signal app (developed by WhisperSystems). Also, Signal has the ability to put a password on the entrance to the application itself, so that no one reads when the owner of the phone is not nearby. Whatsapp, viber - already mauvais ton, as it seems to me. But telegram works noticeably faster, but for that, it does not know how to VoIP. And at the signal they (calls) are also encrypted.

There are two options for sending messages in a telegram: a regular message and a secure message (you can set a self-destruct timer). And if, according to the first option, the messages are duplicated on all your devices, then the second ones are only between two devices and you will erase them anyway as soon as you finish the conversation and no traces will remain with the specials. services (because they are encrypted during transmission)
p.s. And an example from your story is most likely that "friend" got access to the phone and quickly leaked the story. The capabilities of the special services are also limited and no one will unnecessarily dig into the trash of all users and identify the correspondence of a specific addressee for the entire period.

Almost everything is protected from the usual KGB officer. To get access to a person’s WhatsApp, it’s not enough to put a bottle of Mikhalych or light up with a crust.

All cellular companies that operate in Russia are controlled by Russian special services, in order to read the correspondence of any person, they clone your phone number in 2 clicks and restore all the correspondence of your messenger. Simply and easily. It's the secret services. None of the presented messengers on the market has full protection. This is if we talk about the special services. Well, for the common people, encryption is of course 100%!)) In general, we do not violate the laws of the Russian Federation and live without problems)))
