  • Usually they’re normal x86 PCs with nothing unusual about them so just your Linux/BSD distro of choice. You can look up the processor model to see what crypto acceleration it can do, or see if there’s any wireguard benchmarks available.

    Some have interesting processors like PowerPC, or other strange hardware, but avoid them unless interesting is what you’re after.








  • Most mass-marketed VPN services (the type marketed for accessing the internet) allow you to VPN into their private subnet where the thing you can access is their gateway router (which you use in place of your home gateway router/modem for connecting to the internet). You don’t need a VPN service to use VPN software between two points you control.








  • […] the attack is an extremely expensive nation state level operation that doesn’t scale.

    About $250 at most. Quoting the linked page:

    Below is a list of equipment we used for the experiments.

    • (1) Software Defined Ratio (SDR): Ettus USRP B210 USRP, ~$2100.
    • (2) Low Noise Amplifier (LNA): Foresight Intelligence FSTRFAMP06 LNA, ~$200.
    • (3) Directional Antenna: A common outdoor Log-periodic directional antenna (LPDA), ~$15.
    • (4) A laptop, of course.

    Note that the equipment can be replaced with cheaper counterparts. For example, USRP B210 can be replaced with RTL-SDR that costs ~$30.

    To reproduce the attack: our GitHub repository provides the codes and instructions for reproducing and understanding the attack. We have prepared a ready-to-use software tool that can produce real-time reconstructions of the eavesdropped videos with EM signal input from the USRP device.
