The 'Hidden Networks' Created With USB Devices by Fran Ramírez
April 18, 2018. We have been researching the Hidden Networks for a long time at ElevenPaths. These networks or interconnections between isolated computers, that might be separated by different subnets or in other locations, were created using USB devices plugged into several computers within a corporate network.

Thus, it would be possible to spread a malware between computers totally isolated from the Internet, like the well-known Stuxnet incident.
Seeking how to implement this hidden network analysis, a couple of months ago we published some scripts in PowerShell that analyzed these networks. Now we have created a PoC in Python called “HN” (Hidden Networks) which automate all the processes in order to gather the information, both local or over a network (domain). It then plots the hidden network as a graph. In this talk we are going to describe the internal functionality of the main parts of this HN tool.
