NRC - NSA Infected 50,000 Computer Networks with Malicious Software

At this point, I'm going to leave it to the SOURCE to lay the land:

The American intelligence service - NSA - infected more than 50,000 computer networks worldwide with malicious software designed to steal sensitive information. Documents provided by former NSA-employee Edward Snowden and seen by this newspaper, prove this.
A management presentation dating from 2012 explains how the NSA collects information worldwide. In addition, the presentation shows that the intelligence service uses ‘Computer Network Exploitation’ (CNE) in more than 50,000 locations. CNE is the secret infiltration of computer systems achieved by installing malware, malicious software. [source NRC]
