Al-Qaeda 's response : Last year, after the Snowden leaks, the US government warned that the revelations would make the agency's job, which according to protocol is to monitor those trying to harm the United States, and to notify of impending terrorist attacks, much more difficult.

In response to the NSA revelations, Al-Qaeda terrorists have begun using stronger encryption techniques to avoid leaks, according to a recent report published by intelligence and threat analysis firm Recorded Future.
The analysis conducted by the intelligence firm revealed that major terrorist organizations such as Al-Qaeda have changed their encryption software for the first time in seven years, following the revelations of the US National Security Agency (NSA) by Edward Snowden.
As you already know, Al-Qaeda is a global military, Islamic organization that operates as a network that includes a multinational army and a radical movement of Sunni Muslims striving for global jihad.
Since 2007, Al-Qaeda has been using its own built-in encryption software, Mujahideen Secrets, for its online connections as well as for its telephone communications. The intelligence firm Recorded Future noted that they are now using some new encryption tools and have adopted new services such as mobile phones, instant messaging, and even Mac computers to hide their communications.
“The nature of these new crypto products indicates a strategy of using stronger and more widespread encryption in the West (primarily the US),” the report says.
Three different terrorist organizations linked to Al-Qaeda (GIMF, Al-Fajr Technical Committee, and ISIS) released three new major encryption tools within three to five months of the first Snowden leaks, according to the report.
These three tools come to enhance the original Mujahideen Secrets encryption tool, which has been primarily used for Al-Qaeda email since 2007.
Recorded Future lists the three tools of Al-Qaeda. If you are interested, you can see them on their website.
