WikiLeaks Reveals CIA Tools Targeting Air-Gapped Devices, Closed Networks

WikiLeaks have released details on CIA programs called 'Brutal Kangaroo' and 'Emotional Simian', which allow the intelligence agency to access closed networks or a singe air-gapped device. 

​The operation involves first infecting one computer, which is referred to as a "primary host", on which the malware is installed. Then, whenever someone uses a USB flash drive, it in turn becomes the malware carrier, which it spreads onto any other device it is being used on. Once the CIA has control of a number of devices, it creates a so-called 'covert network' that allows for larger data exchange.
