Telegram, a messenger at the heart of the war in Ukraine

Telegram messaging is used by more than 500 million people, including many heads of state, including those of Mexico, Taiwan and even… Ukraine. Yet this messaging, which houses the secrets of the world, is much less secure than it seems. Decryption.

Telegram messaging plays a key role in the war between Ukraine and Russia. It is widely used on both sides, including very actively by Ukrainian President Volodymyr Zelensky.

While the groups are limited to 256 people on WhatsApp, those of Telegram can accommodate more than 20,000 participants, which makes them formidable relays of information, opinions, as formidable sounding boards for misinformation.

Recently, this messaging, which is not end-to-end encrypted by default – which makes it much more vulnerable than competitors such as Threema or Olvid for example – was publicly mocked by Moxie Marlinspike, the co-creator of Signal. Pavel Dourov, the creator of Telegram, a native of Saint Petersburg and known for throwing banknotes from the premises of his company, had to recall that he had opposed the FSB several times and that his mother had origins Ukrainians. However, while it has been threatened with closure several times, messaging has not yet been banned by Moscow, unlike WhatsApp and Facebook.
