New to 8ch so sorry if I am doing this wrong I would like to explain my method in which I logged all internet activity in many major airports. This method require your target location of choice to have multiple public usb-c/thunderbolt3 ports that are connected in a AB Pattern(Diagram W.I.P) Your gonna need a laptop (I used a razer blade 15) a eGPU, A router(With tomato Flashed) and a PCI-E Network card you need to remove the card from the eGPU(Tutorials Can be found on Ifixit and other websites depending on model) Then proceed to install your network card into the eGPU. Now Connect the router to your network card. Now you can use any of the easy logging scripts for tomato on your router and grab the results by wiresharking the intel thunderbolt process.
