Encryption, it seems, at long last is winning. End-to-end encrypted communication systems are protecting more of our private communication than ever, making interception of sensitive content as it travels over (insecure) networks like the Internet less of a threat than it once was. All this is good news, unless you're in the business of intercepting sensitive content over networks. Denied access to network traffic, criminals and spies (whether on our side or theirs) will resort to other approaches to get access to data they seek. In practice, that often means exploiting security vulnerabilities in their targets' phones and computers to install surreptitious "spyware" that records conversations and text messages before they can be encrypted. In other words, wiretapping today increasingly involves hacking.

This, as you might imagine, is not without controversy.
