    Security question: does Windows 10 leak my wireless password ?


    Hi,

    I have a Windows 10 Pro device. Yesterday morning, it attempted to connect to "my" wireless network but gave the following error: "Incorrect password". I checked with the router, but the router was in a strange state, it was clearly not working. So Windows 10 was trying to connect to another network with the same SSID? Did it send my wireless password to this unknown network?

    I searched for one day on the internet to see if there is anything in the WPA2 protocol that authenticates a Wireless network before the devices connect to it. I was unable to find a clear answer. A vulnerability such as this would make wireless encryption hilariously useless.

    Your password is never sent in plaintext over the network - only a temporary key derived from the password is used. The 4-way handshake ensures that both the client and AP must know the password before the client will attach (aside from bugs like KRACK). So what you saw may just be due to whatever happened to your router and not necessarily due to someone trying to impersonate your router.
