Insecure DNS lookup, and no TLS between host and router #10

Open aelnosu opened 5 months ago

aelnosu commented 5 months ago

Here is an example kill.txt file

{"Type":"UnencryptedConfiguration","NetworkConfigurations":[{"GUID":"EXAMPLE-wifi","Metered":true,"Name":"EXAMPLE","Type":"WiFi","WiFi":{"AutoConnect":true,"SSID":"EXAMPLE","Security":"None"},"NameServersConfigType":"Static","StaticIPConfig":{"NameServers":["167.86.91.171","66.94.105.229","213.109.163.210","92.60.37.102"]},"ProxySettings":{"Type":"Direct"}}]}

There are a couple of problems with this setup

  1. The NameServers are not trustworthy, there is nothing* preventing the DNS lookup server operator from arbitrarily modifying the DNS lookup table.
  2. This setting completely disables the TLS between the host and the router.

If you wish to contact me privately you can send me an encrypted email with either S/MIME or GPG. Email: aelnosu@outlook.com To obtain my S/MIME public key, just send an S/MIME signed email with the subject:S/MIME Exchange Request.

Sorry for not seeing this. I will be working on encryption of this, and will reach out to you if needed. Thanks!

This issue is closed because it is not a security concern, according to cert.pl

When connected to a protected WiFi network, one should not be able to send any unencrypted data to the router as the encryption is enforced. In other words, if the WiFi is a protected one, it should not be possible to disable the encryption.

The only problem I see is the DNS server being compromised.

I don't really see the DNS servers getting hacked. I have security measures in place, which should be pretty hard to near impossible to hack into.
