In 2013, Edward Snowden explained that the US NSA and the British GCHQ were spying on various administrations in Europe and there was a scandal in the mood of all.

But how did they spy?

On November 23, the company Symantec reported that it had discovered the spy system used in the attack. The agencies mentioned above reportedly used the Regin virus for a long time. Belgacom, a company that manages communications from the European Commission, could be responsible for introducing the virus into the computer systems that have to be spied on and develop its work in several stages.

First, a fake page of the LinkedIn professional network was sent to several technicians and when the page was opened one or more of them hid the virus on their computers using the file names that Microsoft uses. He then settled in the core, which is the heart of computers and servers, and erased all the traces he had left in his trajectory.

Through these viruses, human spies managed to control thousands of computers and had access to thousands of private and confidential documents.
