The NSA infected more than 50,000 computer networks across the globe with malware capable of collecting sensitive information, reports NRC Handelsblad. The figure is based on documents leaked by Edward Snowden and is reportedly current as of the middle of last year. The malware is said to be distributed by the NSAs Tailored Access Operations group (TAO), the activities of which were also detailed in August by The Washington Post. Like the Posts report, this malware is said to function as a digital sleeper cell: it can be remotely turned on and off at the NSAs command. The number of infected computer networks reported by NRC sounds right on track with NSA estimates reported by the Post in August.
