The DHS was recently polled on what groups and attacks they are personally most concerned about. This comes from a pretty wide range of intelligence officers at various levels of the military industrial complex. This underscores how the military is thinking and what they are currently most focused on. The tidbits I found interesting are on pages 7 and 8:
The DHS seems to be most concerned about Sovereign Citizens and Islamic Extremists/Jihadists (in that order). The rationale isn’t well explained, but I would presume that physical proximity and the radical nature of Sovereign Citizen groups trumps the extremist nature of Jihadists. I’m speculating, but that would seem to make sense. It could also be a reaction to FUD, but it’s hard to say.
More interestingly, the threat they find most viable is Cyberterrorism. That makes a lot of sense, because Cyberterrorism is cheap, can be done instantaneously, can be done remotely, and can be done with minimal skills and at minimal risk. It’s really hard to tell what’s Cyberterrorism versus what is just a normal for-profit attack, and attribution is largely an un-solvable problem if the attacker knows what they’re doing. Also, even if you can identify the correct adversary, extradition/rendition are tough problems.
There’s not a lot of substance here, because it’s all polls, but it’s interesting to see that our industry is at the top of the US intelligence community’s mind.
