An app that’s become notorious because of its popularity with terrorists just announced that it now has 100 million monthly users.
Telegram announced on Tuesday that the app now delivers 15 billion messages a day, with 350,000 new users signing up daily.
The app was created by brothers Nikolai and Pavel Durov, who wanted a secure and private way to communicate. The brothers are also known for launching Russia’s biggest social networking site, VKontakte.
Western officials and counterterrorism experts have become increasingly worried about the encrypted communications the terrorist group ISIS (also known as the Islamic State, ISIL, or Daesh) uses to evade authorities and disseminate its propaganda, including through apps like Telegram.
“Terrorists are using encrypted communications and … very solid cryptography standards that haven’t been broken yet,” said David Kennedy, the CEO of TrustedSec, who has worked with the Marine Corps’ cyber-warfare unit and the National Security Agency.
“The terrorists are getting very smart on their mode of communications.”
CIA Director John Brennan told an audience at the Center for Strategic and International Studies late last year that terrorists “have gone to school on what they need to do in order to keep their activities concealed from the authorities.”
“I do think this is a time for particularly Europe as well as the US for us to take a look and see whether or not there have been some inadvertent or intentional gaps that have been created in the ability of intelligence services to protect the people that they are asked to serve,” Brennan said.
US officials have been trying to figure out where those gaps are in light of the terror attacks on Paris, for which ISIS claimed responsibility.
“It is too early to know for sure, but plainly ISIS took steps to conceal this plot from our detection and successfully so,” Rep. Adam Schiff (D-California), the ranking member of the House Intelligence Committee, told Business Insider in a statement last year. “We may learn that the use of encrypted platforms was one part of their operational security, but I don’t believe it alone can explain missing such a large and complex coordinated attack.”
It’s not clear how exactly the Paris terrorists communicated to plot the attacks, but authorities have reportedly found evidence that at least some of the terrorists used Telegram. And encrypted messaging has created difficulties for intelligence agencies more broadly when dealing with terrorism.
Some experts have cast doubt on the characterization of Telegram’s encryption as nearly impenetrable. But nevertheless, it’s not easy to crack.
ISIS terrorists are known to use encrypted communications to recruit people, disseminate propaganda, and message its members privately.
In an October report for the Combatting Terrorism Center at West Point, ISIS expert J.M. Berger wrote that “Islamic State recruiters often favour messaging applications with strong encryption.”
“Among the most popular are WhatsApp, Kik, Surespot, and Telegram,” Berger wrote. “… The shift to such applications has been described by FBI Director James Comey as ‘going dark’ — the point at which continued monitoring by law enforcement becomes problematic.”
ISIS doesn’t appear to rely on any one platform to communicate publicly and privately. But experts have noted a troubling shift, in particular, to Telegram.
Nikolai and Pavel launched Telegram in 2013. The idea sprang from a run-in with the law in Russia.
Pavel fled Russia after VKontakte caught the Kremlin’s attention and allies of Russian President Vladimir Putin took control of the social network, according to The New York Times. Pavel said he came up with the idea for Telegram when he called his brother during a SWAT standoff at his home in St. Petersburg. The standoff followed 2011 demonstrations over parliamentary elections.
“I realised I don’t have a safe means of communications” with my brother, Durov told The Times. “That’s how Telegram started.”
Telegram has not yet achieved the reach of other messaging apps like WhatsApp, which was founded in 2009 and has several hundred million monthly active users.
Still, Telegram was able to reach millions of people without outside investors, ads, and marketing, Pavel told The Times in 2014. The app is available to download for free, and a phone number is the only requirement that goes along with signing up.
The company operates as a non-profit to avoid commercial and legal pressure, according to TechCrunch.
Pavel did not respond to a request for comment from Business Insider.
Channels and private chats
Part of what has made Telegram so appealing to terror groups is the heightened encryption and “channels” (which were introduced in September) that allow users to broadcast to an unlimited number of subscribers.
Users can also share their contact information easily via usernames and links — if you don’t want a person to know your phone number, for example, you can create a username and send the person a link to the app.
Once the person clicks, it launches the app and opens a chat (or channel) with the username on the link.
The usernames and links make it easy for ISIS recruiters to share their Telegram contact information on larger platforms like Twitter without exposing the phone numbers attached to the usernames.
Hassan Hassan, an associate fellow at the Chatham House and an expert on ISIS and Syria, told Business Insider that it’s also easier to fake your phone number on Telegram than on other messaging platforms like WhatsApp.
ISIS members “don’t want to be tracked so they use fake numbers,” Hassan said in an email last year. “… They use these apps so they can send out their messages and communicate securely and without their identities being known.”
“They don’t want to be legally tied to a phone number and a pro-jihad Telegram account.”
Hassan explained that ISIS members are typically told use a strong virtual private network (or VPN), which can obscure a user’s Internet Protocol address and protect his or her data, enable the two-step verification feature on Telegram, and then link it to an encrypted secure mailbox.
ISIS Telegram channels have sent out instructions on how to enable two-step verification:
Telegram also has a “secret chat” feature that goes the extra mile to protect the messages from being intercepted. As Telegram’s website explains:
Telegram’s special secret chats use end-to-end encryption, leave no trace on our servers, support self-destructing messages and don’t allow forwarding. About the only thing secret chats don’t have is cloud storage — they can only be accessed on their devices of origin.
Kennedy explained this encryption method: “The actual communications won’t flow through servers, they will flow directly to individuals, so there’s no middle person to intercept the communications.”
And Telegram’s self-destruct feature allows users to set a time limit on the messages — they will automatically delete once a certain amount of time has passed after the recipient opens the message. Users can set messages to delete anywhere from one second to one week after it’s opened.
“They are using military-grade encryption,” Kennedy, the TrustedSec CEO, told Business Insider. “Most of the keys are actually stored on each individual system so that makes it very difficult to get any information in the middle. Think of it as an encrypted tunnel.”
Combined with Telegram’s prior unwillingness to suspend users who appear to be affiliated with terrorist groups, the app has become a convenient platform for jihadis who want to disseminate their message easily to a large audience and communicate one-on-one without worrying about their messages being easily intercepted by intelligence agencies.
At the TechCrunch Disrupt conference in September, Pavel was asked specifically about ISIS using the app. He said then that privacy took precedence.
“Privacy is ultimately more important than our fear of bad things happening, like terrorism,” Pavel said, according to VentureBeat. “If you look at ISIS, yes, there’s a war going on in the Middle East. Ultimately, ISIS will find a way to communicate with its cells, and if any means doesn’t feel secure to them, they will [find something else]. We shouldn’t feel guilty about it. We’re still doing the right thing, protecting our users’ privacy.”
Pavel’s comments illustrate the central struggle of stopping terrorism in the internet age — it’s difficult to give governments enough access to intercept terrorist communications without potentially sacrificing everyone else’s privacy.
“Unfortunately today you can’t have it both ways: a government that can eavesdrop on communications … and privacy for personal cryptography,” Kennedy said. “… [These terrorists understand communications, they understand technology. … This is the next generation of terrorism.”
Since Pavel’s comments at the TechCrunch conference, however, Telegram seems to have changed its stance. After the Paris attacks, the company suspended dozens of ISIS-affiliated channels and announced in a statement that it would block terrorist channels.
ISIS propaganda channels
ISIS’ Telegram users are very active, sending out hundreds of updates per day — including video, audio, photos, and text statements.
Channel subscribers can’t post anything in the channels, but subscribing gives users quick and easy access to all of ISIS’ latest releases.
“In the aftermath of Paris, propaganda was released on Telegram and on Twitter,” Rachel Bryson, a researcher at the Quilliam Foundation who studies ISIS propaganda, told Business Insider. “… They will have a Twitter account where they announce on Twitter to follow them on Telegram, so you can subscribe to the account on Telegram.”
Media released on Telegram in the wake of the terror attacks then showed up on Twitter and other online platforms.
“The top tier of disseminates have Telegram accounts, but Twitter is still a mass-audience platform,” Charlie Winter, a researcher on jihadism and expert on ISIS propaganda, told Business Insider last year.
The propaganda oscillates from bucolic to brutal — photos of sunsets and shops are mixed in with photos of amputations and airstrikes. Though ISIS certainly uses violence to recruit, it also markets its “caliphate” as an Islamic utopia, emphasising the government services, food, and other goods that it says are available in its territory in Iraq and Syria.
This method of marketing might especially resonate with those living in war zones who don’t have regular access to basic necessities.
“There’s so much more focus on civilian life than anything else,” Winter said. “It’s justifying [ISIS’] existence and reason for being.”
Here’s a look at the wide variety of images that pop up:
ISIS’ official propaganda channels come across as an exercise in branding — the group also dedicates a lot of its messaging to making ISIS look like a full-fledged state with a well-functioning and disciplined military.
Recently, ISIS propaganda channels on Telegram posted photos showing ISIS militants learning martial arts and engaging in various military exercises.
The photos and statements in ISIS’ official channels come from its media shops around ISIS territory. ISIS has put a lot of effort into its media strategy, which is highly sophisticated for a terrorist group. The group regularly produces slick videos and a glossy English-language magazine, along with maintaining an active presence on social media for indoctrinating, recruiting, and disseminating its messages.
Many of the group’s channels on Telegram have now been blocked, but new ones keep popping up, and their system for attracting followers seems to be similar to the tactics they use on Twitter.
One account gets shut down, and a new one pops up in its place. When an ISIS-affiliated Twitter account gets suspended, the user will often create a new account with a similar handle, noting in their new Twitter bio how many times they have been suspended, and then notify a “shoutout” account (which are also often suspended) to mention the new handle and ask other ISIS-supporters on Twitter to follow it.
Meanwhile, some of the new Telegram channels that have popped up this week are distributing what looks to be official ISIS propaganda in light of the official ISIS Telegram channels (all bearing the name “Nashir”) being shut down.
For its part, ISIS declared “war” on Telegram after the company started shutting down its channels. ISIS-affiliated channels that hadn’t yet been blocked released this statement:
they started their war on the #islamicState
be very careful and from now on nothing is save to use
they can give away our info
so keep using VPN and
be carefull may Allah protect you
