  • Got in touch with ProtonVPN support and asked about this. Here’s their reply:

    Our engineers have conducted a thorough analysis of this threat, reconstructed it experimentally, and tested it on Proton VPN.

    We concluded that:

    1. The attack can only be carried out if the local network itself is compromised
    2. Our Windows and Android apps are protected against it
    3. For iOS and macOS apps, you are completely protected from this as long as you’re using a Kill Switch and a WireGuard-based protocol (our apps use them by default, and if a user wants to use something other than WireGuard derivates, they’d have to manually set it up). Note that Stealth, WireGuard TCP and Smart protocol on iOS/macOS are all WireGuard-based.
    4. For our Linux app, we’re working on a fix that would provide full protection against it.














  • All VPN software might affect bandwidth due to the increased progressing needed for encryption, but quantifying it is hard because several factors come into play : mainly the hardware and bandwidth on either side of the tunnel. Giving it a go is easy and you can check which VPS specs give you the speed you require. Regarding the number of connections, I’m not sure of the answer. For all intents and purposes I don’t run into a lot of problems on a daily basis and bandwidth is acceptable on a cheap 4€/mo VPS with 2 CPUs. Bonus tip for privacy, you can use port 443 for wireguard which makes it less obvious you’re using a VPN.
