Telegram, a highly encrypted messaging app used by Islamic State (IS) to spread propaganda and recruit fighters, has taken down public posts made by the terrorist group days after the Paris attacks.
The Berlin-based service, which has 62 million monthly active users, has grown in popularity because of its end-to-end encryption method which makes messaging between people ultra-secure. It means that no hackers can snoop on a conversation that is taking place via the app.
But Telegram also has a feature called "Channels" which allows a person to broadcast a message to an unlimited number of people and in public. This was being used by IS to distribute propaganda and advertisements encouraging people to donate money to the group, according to researchers at private intelligence agency Flashpoint.
As a result, Telegram said on Wednesday in a statement that it has "blocked 78 ISIS-related channels across 12 languages", adding that it was introducing an "easier way for our users to report objectionable public content in the upcoming update of Telegram this week".
