Network Proxy not detecting accurately

[sp00ks-git]

I can see when running winpwn.ps1 that the proxy i have isnt being detected although it is in place.

Searching for network proxy...
No proxy detected, continuing...
Straight after the 'True' Statement from the amsi bypass i get:

Exception calling "DownloadString" with "1" argument(s): "The remote server returned an error: (407) Proxy Authentication
Required."

I can confirm I have a proxy in place.

[sp00ks-git]

I can confirm by adding in my current credentials manually and get a 200 response.

$Wcl=New-Object System.Net.WebClient
$Creds=Get-Credential
$Wcl.Proxy.Credentials=$Creds
Invoke-WebRequest http://www.google.co.uk

StatusCode : 200
StatusDescription : OK

Is the environment using PAC files for proxy distribution? You should be able to look this up in the IE config for example.

I never had the time so far to implement PAC-file support/parsing.

Yes I can confirm the setup uses a PAC.
