Telegram app is French terror concern
Paris - Smartphone app Telegram, favoured by the Islamic State (ISIS) thanks to the encrypted messaging it offers, is proving to be a headache for French anti-terror investigators.
The free-to-download instant messenger, which allows people to exchange messages, photos and videos in groups of up to 5,000 people, has attracted 100 million users since its launch in 2013.
It contains features that make it particularly attractive to jihadists, who cannot only rest assured that their private messages are out of the reach of intelligence officials but can also disperse propaganda on YouTube-like public channels.
After ISIS gunmen and suicide bombers massacred 130 people in Paris in November, Telegram blocked dozens of public channels that were being used to spread extremist messages but Russian internet guru Pavel Durov, who founded Telegram with his brother Nikolai, insisted that not even he has the power to intercept users’ private chats.
In France, which has suffered a string of additional jihadist assaults since the Paris carnage, investigators are dealing with the fallout from the communications of an ISIS member suspected of using Telegram to direct people to carry out attacks.
Rachid Kassim, a 29-year-old Frenchman who has regularly appeared in ISIS propaganda videos shot in Syria or Iraq, was able to urge some 300 contacts to commit attacks on home soil, notably publishing a list of targets and scenarios for how to carry them out.
Among his contacts were Larossi Abballa, who stabbed to death a senior policeman and his partner in the Parisian suburbs in June and two teenage jihadists who cut the throat of a Catholic priest in a northern French church in July.
Kassim was in the news recently after it emerged that female jihadists suspected of plotting to blow up a car filled with gas canisters near Paris’ Notre Dame cathedral were on his contact list.
Unable to get past Telegram’s impenetrable encryption, the best intelligence officials can hope for is to sneak into extremist chatrooms by posing as jihadists but they are bound to attract suspicion unless they talk the talk convincingly.
“Infiltrating is possible but you have to be a good actor and have a lot of cultural and religious awareness to get away with it,” one investigator said.
So confident is Telegram in its encryption that it has offered up to $300,000 to anyone who manages to crack its system. The app has a feature that allows users to set messages to auto-destruct, making it impossible to recover them later for use in investigations.
Even in the realm of public jihadist propaganda on Telegram, it is “practically impossible to track the millions of messages that are exchanged every hour”, one investigator lamented.
French intelligence chief Patrick Calvar described the app in May as “the main network used by terrorists”.
“We bump into encryption problems on a daily basis, as the means of communication multiply along with the amount of data that we have to gather,” he said, adding that encryption is “a major question that only international conventions can decide on”.
The use of such apps, which soared after Edward Snowden’s revelations of mass US surveillance in 2013, has sparked debate over the balance between internet users’ right to privacy and the need for security agencies to protect the public.
The Interior ministers of France and Germany have urged the European Commission to regulate encrypted messaging apps.
Telegram’s developers said after the Paris attacks that they were “disturbed” it was being used by jihadists but they are staunchly pro-privacy and have blasted internet giants Facebook and Google for giving data to third parties.
French investigators said they do not know who within the Berlin-based company they should legally petition for information that could help piece together a case, such as confirmation that a suspect is the holder of a particular Telegram account.
“We do not know who in Telegram to send our requests to — there is no judicial entity or legal department like there is at Apple or Microsoft,” one investigator said.
