Telegram less secure than Messenger and WhatsApp, says Signal founder

Instant messaging app Telegram was for several months considered an alternative to WhatsApp, especially when it comes to confidentiality. However, this is an error according to Moxie Marlinspike, founder of Signal, who believes that Telegram is not safer than applying Meta(Facebook). On Twitter, he indicated in a thread that Telegram is not a “Encrypted messaging”.

The information is saved on Telegram’s servers

“It’s amazing to me that after all this time, almost all of Telegram’s media coverage still calls it ‘encrypted messaging’. Telegram has a lot of great features, but when it comes to privacy and data collection, there is no worse choice ” he let see on the social network. Indeed, according to Moxie Marlinspike, all messages, contacts and groups are saved on the servers of Telegram, allowing the application to read them at any time. To justify his claims, the founder of Signal offered a test. “Delete Telegram, install it on a brand new phone, and register with your number. You will immediately see all your conversation history, all your contacts, all the media you have shared, all your groups. How? ‘Or’ What ? Everything was on their servers, in the clear ” he made clear.

For Moxie Marlinspike, the fact that we attribute to Telegram the name of “Encrypted messaging” is explained by the fact that the application offers a secret mode “Very limited”, which is not enabled by default. In this sense, he made it known that Facebook Messenger uses this same way of doing things, pointing out however that the secret mode of this one is less limited than that of Telegram. As it concerns WhatsApp, remember that exchanges are end-to-end encrypted by default. This means that the information is not readable when it goes to Facebook’s servers.

Telegram is actually less secure than Messenger and WhatsApp!

Today, Telegram is considered a secure messaging service, and one of the main alternatives to WhatsApp. Its boss, Pavel Durov, also regularly criticizes its main competitor.

And when there’s an issue on WhatsApp (like a privacy controversy or a giant outage), people flock to Telegram. Yet, according to Moxie Marlinspike, the founder of Signal, Telegram is not as secure as you think.

“It’s amazing to me that after all this time, almost all of Telegram’s media coverage still calls it ‘encrypted messaging’. Telegram has a lot of great features, but when it comes to privacy and data collection, there is no worse choice, ”he wrote in a thread on Twitter.

Encryption that is not enabled by default

This explains that Telegram stores all your contacts, groups, media, and messages in clear text on its servers. And, in essence, the courier can read everything.

To demonstrate this, Marlinspike offers a simple test. “Delete Telegram, install it on a brand new phone, and register with your number. You will immediately see all your conversation history, all your contacts, all the media you have shared, all your groups. How? ‘Or’ What ? Everything was on their servers, in clear, ”explains the founder of Signal.

For him, the confusion stems from the fact that Telegram offers a “very limited” secret mode that allows you to protect your messages with end-to-end encryption. This encryption is therefore not offered by default.

Also, for the founder of Signal, Telegram is comparable to Facebook Messenger, on which messages are not end-to-end encrypted by default, but which allows you to protect your conversations using a “secret” mode. In addition, Marlinspike considers that the secret mode of Facebook Messenger is less limited than that of Telegram.

Telegram and Messenger, the same thing?

The thread doesn’t mention WhatsApp. However, it is important to remember that on WhatsApp, conversations are end-to-end encrypted. And because of this, the content is not readable when it passes through Facebook’s servers.

Besides, if you delete WhatsApp from your smartphone and have not made a backup, you lose all your data!

For Moxie Marlinspike, Telegram should therefore not be considered “encrypted messaging”. This one also calls out the media on this subject: “my request is that when you write“ encrypted messaging ”, that should at * minimum * mean an application where all the messages are e2ee (note, encrypted from end to end) by fault. Telegram and FB Messenger are built exactly the same. None of them are “encrypted messaging” ”.

This post comes at a time when Signal, the app whose Marlinspike is increasingly turning to the general public.

In its early days, this app was seen as a service for journalists, whistleblowers, who can be targets for hackers and governments. But currently Signal also wants to attract ordinary users.
