Terrorist and extremist groups like ISIS, al-Qaeda, Hamas, Hezbollah, and others use encrypted application Telegram to recruit new members, fundraise, incite to violence, and even coordinate terrorist activity. Telegram’s messaging application has both public-facing and private components. This flexible interface enables extremists to do everything from self-promotion, brand development and propaganda dissemination, to secret plotting of attacks outside detection or interference from law enforcement.
Brief History of Telegram and Terrorism
For years, ISIS has used a variety of online platforms—including Twitter and WhatsApp among others—to communicate with recruits and operatives, issue claims of responsibility for attacks, and disseminate news updates and propaganda materials. In January 2015, the group even circulated a list of recommended private messaging applications, ranking them from least to most “secure.” At the time, ISIS considered Telegram to be a ‘safe’ or secure communications application and accordingly recommended its use.

ISIS has encouraged its followers on Twitter and other social media sites to connect with ISIS coordinators and recruiters on Telegram to discuss sensitive matters such as travel to ISIS-held territory. ISIS also created public channels on Telegram to broadcast pro-ISIS news updates and disseminate other propaganda materials through its Amaq Agency news outlet.


The ISIS presence online has caused considerable concern among authorities. However, at a TechCrunch conference in September 2015, Telegram founder Pavel Durov dismissed these concerns, asserting that “[t]he right for privacy is more important [to Telegram] than our fear of bad things happening, like terrorism.” Two months later, ISIS carried out the deadliest terrorist attack on French soil since World War II, killing 130 people and wounding 350 more. According to French investigators, the group had relied in part on Telegram and WhatsApp to coordinate and plan the attacks. (Sources: YouTube, International Business Times)
Since the Paris attacks, Telegram has revised its formal position, pledging to remove ISIS accounts from public channels. The company has, however, adamantly refused to take down private ISIS chats, where the attacks coordination is believed to take place. As Telegram says on its Frequently Asked Questions page, “All Telegram chats and group chats are private amongst their participants. We do not process any requests related to them [emphasis added].” While Telegram pledges to block ISIS-related “bots and channels, we will not block anybody who peacefully expresses alternative opinions [emphasis added].” (Source: Telegram)
Telegram’s contradictory position toward ISIS and other terrorist organizations has allowed these groups to continue to operate on the platform with relative impunity. Although Telegram removes some public ISIS channels from its platform, ISIS’s Amaq Agency frequently reappears to claim responsibility for terrorist attacks and disseminate propaganda materials. On March 23, 2017, for example, ISIS used the platform to claim responsibility for the lone-wolf terrorist attack the day before in London, which left four people dead and more than a dozen wounded. On May 23, 2017, ISIS again claimed responsibility for the Manchester Arena attack, releasing responsibility claims and other propaganda materials on Telegram.

Other extremist and terrorist groups continue to operate freely on Telegram without comment by Telegram. Telegram continues to host channels operating on behalf of internationally-sanctioned terrorist organizations, including al-Qaeda, the Nusra Front, Hamas, Hezbollah, and the Taliban.



Telegram has remained noticeably silent on the presence of these and other terrorist groups. In some instances, the aforementioned channels have remained operational for well over a year without takedown.
How Terrorists Use Telegram: Channels and Chats
The Telegram platform consists of public channels and private chats. Terrorists have co-opted both forms of communication to distribute propaganda, incite to violence, coordinate travel to foreign conflicts, and claim responsibility for terrorist attacks.
Channels
Telegram channels allow ISIS, al-Qaeda, Hamas, the Taliban, and other extremist and terrorist groups to broadcast messages to groups of followers at once. CEP has collected examples demonstrating how terrorist-affiliated channels on Telegram publish propaganda materials to subscribers, claim responsibility for attacks, issue calls to action, and solicit donations.

Groups like ISIS have also issued calls to violence on Telegram channels in advance of major attacks. On December 6, 2016, one such message read, “Christmas, Hanukah, And New Years [sic] Day is very soon Insha Allah[.] So let’s prepare a gift for the filthy pigs/apes.” Less than two weeks later, Tunisian suspect Anis Amri plowed a truck into a crowd of people at a Christmas market in Berlin, killing 12 people and injuring 48 others. ISIS also claimed responsibility on Telegram for the New Year’s Eve shooting attack at an Istanbul nightclub. The attack left 39 people dead and dozens wounded.

ISIS Chats
ISIS encourages individuals demonstrating support for ISIS on platforms like Twitter, YouTube, and WordPress—as well as through Telegram’s public channels — to contact the group privately on secure messaging platforms like WhatsApp, Viber, or Telegram’s secure chat platform.
Telegram’s chats can accommodate up to 5,000 members. ISIS’s supporters use chats to share pro-ISIS content amongst themselves.
Once on the Telegram’s secure chat platform, ISIS operatives can engage with its followers one-on-one or in small groups to plan attacks or coordinate travel to and from ISIS-held territory. Telegram’s chats can accommodate up to 5,000 members. For that reason, ISIS’s supporters also use the chat platform to share pro-ISIS content amongst themselves, chatting and sharing links on the newest ISIS videos, magazines, and attacks claims. ISIS supporters on Telegram often try to vet journalists, analysts, and others—whom they refer to as “spies”—so they can share pro-ISIS content amongst themselves.

Telegram has today surpassed Twitter as ISIS’s “most important platform,” according to counterterrorism expert Steven Stalinsky. In the past, ISIS would typically coordinate its PR campaigns on Twitter and other social media platforms, sharing the relevant materials—posters, statements, hashtags, and links to ISIS videos hosted on other sites like JustPaste.it, SendVid, and Internet Archive—amongst themselves before pushing the materials out en masse. This process has now largely moved to Telegram, where ISIS operatives often first coordinate ISIS PR campaigns in secret, before deploying them across other social media platforms, like Twitter and YouTube.

From Telegram to Terrorism
Terrorists have used Telegram in the lead-up to a number of successful and thwarted terrorist attacks worldwide:
Conclusion: End Terrorists' Access to Telegram
Telegram has been reluctant to respond seriously to the threat of terrorist activity on its platform. Telegram CEO Pavel Durov has refused to take any steps to curtail ISIS’s access to Telegram’s private chats despite evidence that the platform has been used to plan and coordinate attacks. ISIS’s Amaq Agency channel also continues to appear regularly on Telegram to issue attack claims, propaganda videos, and threats of violence. Notably, Durov has refused to publicly address concerns of other terrorist groups operating on his platform, including the Taliban and al-Qaeda.
It is clear that more can and should be done. Terrorists continue to use Telegram to plan attacks and recruit followers in North America, Europe, the Middle East, and Southeast Asia. And despite efforts by Durov to present Telegram as a refuge for privacy and encryption, the company has become a safe haven for groups like ISIS, Hamas, al-Qaeda, the Taliban. Until we take serious efforts to reduce terrorists’ access to Telegram and other platforms, these groups will continue to inflict violence on civilians around the world, destabilizing the countries where attacks occur, and reducing a global sense of security and safety.
