The encrypted messaging service Telegram blocked 78 ISIS channels in 2015, but new ones just keep popping up. As detailed in a report provided to The Hill, the group has evolved an expanded technical "help desk" that can provide instructions to jihadists on how to escape the surveillance of Western authorities. It's operated by a group of ISIS members collectively called the Electronic Horizon Foundation (EHF), which was launched on January 30th. As of the beginning of this week, its Telegram channel had 2,200 members, although it hasn't posted much yet.
