This is an attempt to collate all the information about ISIS comms within Europe, back to ISIS Syria. This is only operational terrorist comms, not propaganda or fanboy comms. There are links to source material and a summary of what is known.

The clear takeaway from this list is that: 1) ISIS doesn’t use very much encryption, 2) ISIS is inconsistent in their tradecraft. There is no sign of evolutionary progress, rather it seems more slapdash and haphazard. People use what they feel like using and whatever is convenient.
