Here are the security measures NSA spies hate the most

It’s tempting to imagine that few online safeguards will stop NSA surveillance in its tracks, but that’s not true. A new leak from Edward Snowden’s files reveals that there’s a surprising number of ways to thwart these snoops, at least as of 2012.
