The Internet has been buzzing with reports of the recently leaked NSA exploits, backdoors, and hacking / surveillance tools. The linked article is good example.
None of this should be news to anyone paying attention. Many similar hacking tools are available from vendors at conferences like BlackHat and DefCon.
We all know that zero-day exploits exist, and things like Stuxnet clearly show that governments collect them.
Intentionally introducing compromised crypto into the commercial stream has a long history, perhaps best demonstrated by the continued sales of Enigma machines to national governments long after it had been cracked by the US and others.
This reminds me of a quote I posted back in March. Brian Snow, former NSA Information Assurance Director said “Your cyber systems continue to function and serve you not due to the expertise of your security staff but solely due to the sufferance of your opponents.”
One can focus on making this difficult, but none of us should be under the illusion that we can make it impossible. If you have something that absolutely must be protected, and upon which your life or liberty depends, then you need to be taking drastic steps, including total air gaps.
For the rest of your activities, you can use email encryption, disk encryption, VPNs, and other tools to make it as difficult as possible for any adversary to easily vacuum up your information.
If you are of special interest, you may be individually targeted, in which case you should expect your opponent to succeed. Otherwise, someone hacking your computer, or planting a radio enabled USB dongle on your computer is the least of your worries. Your cell phone and social media activities are already hemorrhaging information.
