In addition to its massive monitoring and collection of telephone and Internet data, the US intelligence agency has been extensively infiltrating computer systems around the world and planted malware, Dutch newspaper NRC Handelsblad reported yesterday.
The Amsterdam daily said top secret NSA documents made available by whistle-blower Edward Snowden have revealed that the agency was able to infiltrate over 50,000 computer networks and to install the malware with the help of its Computer Networks Exploration (CNE) programme.
A management presentation of the NSA from 2012 showed that the cyber attacks code-named Tailored Access Operations (TAC) were carried out from a special NSA department, which employed the hackers, the newspaper said.
The NSA malware installed on a computer can remain active for several years without being detected and it can be controlled remotely from the NSA headquarters in Fort Meade, in the US, according to the newspaper.

A similar operation was carried out by Britain's Government Communications Headquarters (GCHQ) to infiltrate the computer networks of the Organisation of Petroleum Exporting Countries (OPEC) in Vienna, the Belgian telecommunications service provider Belgacom and some other companies.
Documents leaked by Snowden earlier showed that the GCHQ manipulated some popular websites to gain access to their computer networks and to plant malware.
Cyber operations are increasingly important for the NSA. Computer hacks are relatively inexpensive and provide the agency with opportunities to obtain information that they otherwise would not have access to, the newspaper said.
The GCHQ has used a programme code-named "Quantum Insert" to hack into various computer systems.
