  • Whatsapp uses the same protocol as signal so MITM is unlikely however there’s no way to know what happens before or after the messages are encrypted/decrypted and sent. They can do that scanning at that stage.

    That is different than Signal which (unless they changed something with the profiles thing) was always P2P E2EE. You’re sending encrypted messages directly to the other persons phone, not to a server.

    Sender cannot know where the recipient is and using P2P would be resource consuming on all client devices (i.e. everyone who uses Signal) so I guess the messages are routed thru Signal’s servers though messages are encrypted on device with keys that only the messaging parties know (couldn’t find an official diagram for this to confirm).











  • When the host routing table is like this:

    $route
    Kernel IP routing table
    Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
    default         192.168.102.1   0.0.0.0         UG    600    0        0 wlp19s0f4u1u1
    default         RT-AC86U-6D60   0.0.0.0         UG    20100  0        0 enp15s0
    

    the VM has internet connection. If the defaults are the other way around it doesn’t.


  • This sounds reasonable. Curiously now that I tried again with both host lan & wlan active there was no problem. I have a hunch the routing depends on which interface networkmanger starts first.

    $route
    Kernel IP routing table
    Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
    default         192.168.102.1   0.0.0.0         UG    600    0        0 wlp19s0f4u1u1
    default         RT-AC86U-6D60   0.0.0.0         UG    20100  0        0 enp15s0
