The NSA is the USA’s spy agency that deals with computery stuff. They are supposed to spy on bad guys and keep us safe by detecting imminent badness and putting a stop to it. Their take on this mission is to spy on everybody all the time, including compromising all the computer systems in the world so they could have access at will.
Including your phone, and your company’s server equipment. All of it. Just in case you turn out to be a bad guy. It’s for your protection, citizen!
Now a second NSA agent has rolled on their organization, and they are giving out additional details in public fora. I wish Jacob Applebaum the best of luck staying alive and out of prison.
