So why did the ISIS prefer Telegram to any other messaging app? According to CNNMoney, Telegram had become popular among ISIS members for its promise of highly encrypted communication and prevent authorites from snooping on them and their activities. Apparently, the startup, has two layers of encryption and is said to be faster and more secure than its competitor WhatsApp. (How safe is safe? And who else is more safe? And why should we care?)
In another article by NBC Sandiego, Telegram also comes with a self-destruct timer which allows users to set a time for an instant message to automatically delete.
There is no doubt that Telegram’s encryption is solid. But, even though Telegram’s encryption is said to be secure, could there be any problems operational use of the program? Here is what Professor Matthew Green, a Cryptographer and a professor at Johns Hopkins University Tweeted about that.

On a separate tweet, Patel Durov, CEO of Telegram still maintains to continue block ISIS related chanels
Our policy is simple: privacy is paramount. Public channels, however, have nothing to do with privacy. ISIS public channels will be blocked.
