The NSA can reportedly hack into computers even if they're not connected to the Internet.
According to NSA documents, American officials and computer experts cited by the New York Times, the NSA uses a secret technology that's like a "radio pathway" into computers, and can access them even if they're not connected.
The reports also claim the NSA has installed secret software on nearly 100 thousand computers to give them access or to use them to launch cyber attacks.
The NSA has allegedly been using this technology since 2008. However, the New York Times says there's no evidence that it's has been used inside the US.
