Right now Islamic State and its followers around the world are using mobile devices to choose targets, discuss methods and timing, and even raise funds. With the aid of encrypted messaging apps—most of which are developed by Western companies—these terrorists can communicate fully out of sight of intelligence and law-enforcement agencies. The murders of countless innocent people have been planned this way, and most Western leaders seem unsure about how to stop it.
Counterterrorism officials are overwhelmed by the sheer number of potential terrorists using these apps on mobile devices. They are further handicapped by their inability to access the encrypted information, which could help them stop attacks. In a January speech at the International Conference on Cyber Security, FBI Director Christopher Wray called the threat from terrorist use of encrypted apps “an urgent public safety issue.” He revealed that, as part of lawful investigations, the FBI had tried and failed to access encrypted information on nearly 8,000 devices in 2017. Appealing to the technology sector for help, Mr. Wray said: “I’m open to all kinds of ideas, because I reject this notion that there could be such a place that no matter what kind of lawful authority you have, it’s utterly beyond reach to protect innocent citizens.”
In response, Sen. Ron Wyden (D., Ore.) wrote a highly critical letter. He called Mr. Wray’s speech “ill-informed” and damaging to America’s security, economy and freedom: “Building secure software is extremely difficult . . . and introducing vulnerabilities would likely create catastrophic unintended consequences that could debilitate software functionality and security entirely.”
