Below are a few choice quotes.
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.
One example of this type of hacking was discovered in September 2013 at the Belgium telecom provider Belgacom. For a number of years the British intelligence service – GCHQ – has been installing this malicious software in the Belgacom network in order to tap their customers’ telephone and data traffic. The Belgacom network was infiltrated by GCHQ through a process of luring employees to a false Linkedin page.
The malware can be controlled remotely and be turned on and off at will. The ‘implants’ act as digital ‘sleeper cells’ that can be activated with a single push of a button. According to the Washington Post, the NSA has been carrying out this type of cyber operation since 1998.
