I am not too worried about Putin.
What I am worried about is this: the Equation malware was used years ago. We know these guys are good at what they do. Very good.
NSA has been working on that stuff since the 1950s -- that's 65 years of experience, folks, and they have been big computer users since day ONE -- heck even before day one, if you count Bletchley Park and stuff like the cracking of Red, Purple and JN cyphers.
So, we are talking about an organization that has huge experience in cracking systems and crypto, and the enormous budget to support its activities.
So: what have they been producing between Equation and, let's say, Stuxnet, and today?
Equation was -- from what I understand -- fairly Windows specific. What have they got now? The stuff coming out of all these not-so-funny super top secret projects?
Here is a hint: combine stuff like Heartbleed (OpenSSL), ShellShock, stuff that lingered in code bases for decades before being found out, maybe other stuff such as a few rumors about OpenSSH backdoors (remember those?) and the "let me install myself cosily in your HDD BIOS where you cannot dislodge me" capabilities of Equation and, presto! No one is safe from the prying eyes of NSA anymore.
That's the kind of things that makes you lose sleep at night. At least, I do lose sleep over it. Georges Orwell had nothing on these guys.
What if you are only running open-source? Vulnerable. Audited open-source? They have 100 times the manpower of the best programming teams out there. Heck, they may even have inflitrated these projects in the first place!
And don't forget one last things: the guys are masters of misdirection. NSA and GCHQ and everyone in between said for years that Enigma was safe to use, even after the nd of WWII. It's extremely simple for these people to say (unofficially, of course) "Drats! This guy is using open source! Foiled again! Damn you open source programmers!! Damn you all to hell!!!", all the while exploiting Linux/BSD machines as easily as "1-2-3". And we know they like subtle.
So, here is the question: what do they have, right now, that we don't know about? Think about that for a second.
