What Is Telegram, and Why Are Iran and Russia Trying to Ban It?

Promising its users protection from the prying eyes of intelligence services, Telegram has become one of the most popular instant messaging apps in the world.

But providing a platform that allows users to evade official scrutiny has brought its own problems. In recent years, the Islamic State has used Telegram to organize terrorism plots, disseminate propaganda and claim responsibility for attacks.

Now, citing national security, the governments of Iran and Russia are leading attempts to block the Telegram app.

Privacy as a Sales Pitch

Telegram started in the wake of revelations by Edward Snowden of large-scale state surveillance in the United States, and it was pitched as a champion of privacy. When Facebook acquired WhatsApp, another messaging startup, Telegram attracted millions of new users.

Although Telegram was founded by a Russian, Pavel Durov, the messaging app rejects any affiliation with Russia. Nonetheless, Alan Woodward, a cybersecurity expert who is a visiting professor at the University of Surrey, in England, said that “the fact that it’s not American” was a major attraction.

Woodward added that many users were suspicious that rivals like WhatsApp or Signal would allow backdoor access to Western intelligence agencies.

Before Telegram’s recent problems, institutions like the Kremlin and figures like Iran’s supreme leader, Ayatollah Ali Khamenei, had been among the messaging app’s 200 million users. But Telegram’s increasing popularity prompted scrutiny from countries like France, where investigators found that the app had become a platform for coordinating terrorism.

The growing criticism led Telegram to ban public channels used by the Islamic State. (The channels are one of its distinctive features, allowing messages to be broadcast to an indefinite number of users.) But Durov and others at Telegram insisted that private messages would remain private.

Telegram’s Founder

Durov, the founder of Telegram, is in exile. But not long ago, he was seen as Russia’s Mark Zuckerberg. Now 33, Durov started a social network, VKontakte, in 2006, when Russia still appeared to have a future as a haven for web freedom. “In some ways, it was more liberal than the United States,” he told The Times almost a decade later, after he chose to leave his country following clashes with the government of President Vladimir Putin.

Durov sold VKontakte, which shared the look and feel of Facebook but was more popular in Russia, and left the country with a reported $300 million in his pocket in 2014. Once abroad, he began Telegram, hoping to offer a service to people who were worried about their privacy.

Since leaving Russia, Durov has roamed the world with a core team of Telegram engineers, recently spending time in Dubai. Durov also holds a passport from St. Kitts and Nevis, a nation in the Caribbean.

So, Is It Totally Watertight?

Telegram uses end-to-end encryption, as do WhatsApp and Signal. This type of encryption converts messages into a code without the help of a server in the middle, making it nearly impossible to gain access to communication between two users without their consent.

But Telegram uses its own secure messaging protocol, called MTProto, and the robustness of that system is up for debate. “Nobody quite knows how it works, and a lot of the security analysis that has been done of it suggests that it’s not as secure as some people think it is,” Woodward said.

The app “has had serious and simple issues in the protocol,” an analysis by researchers at the Massachusetts Institute of Technology found, adding that “any knowledgeable security expert could penetrate” those weaknesses.

Woodward said that Telegram “also leaks a lot of metadata — so who’s calling whom, when, for how long, that type of thing — which can be just as useful for intelligence organizations.” (Signal, by contrast, is said to retain barely any information on its users.)

Balancing Privacy and Security

Western governments have been critical of Telegram’s privacy policy, but have nonetheless appeared reluctant to ban Telegram. The app’s use by terrorists has fueled the debate about the need for surveillance, however.

Some of Telegram’s largest user bases are in Iran and Russia — the very countries that have tried to block the app. (Some users in those countries have been using virtual private networks, or VPNs, to hide their geographical location and in that way circumvent restrictions.)

“The jurisdictions that are blocking it are obviously not the liberal Western democracies that are used to allowing people to talk securely,” Woodward said.

Demonstrations in Russia against the app’s blocking have included prominent opposition figures, including Alexei A. Navalny, the anti-corruption activist; and Maria Alyokhina, a member of the feminist collective Pussy Riot.

Despite the posturing, Durov has pushed against making concerns about Telegram a political issue. “I regard myself as a tech entrepreneur,” he told The Financial Times recently, “not as a politician or philosopher.”
