Block Windows 7

L0 Member

I am trying to block Windows 7 clients from accessing the internet.  I have followed the steps here: https://live.paloaltonetworks.com/t5/Configuration-Articles/Custom-vulnerability-signature-for-ident...

but I am unclear on what to set for the Pattern.  Any suggestions/help to accomplish that goal will be appreciated.

Windows 7 is NT 6.1. You could start there. 

Maybe User-Agent:.+Windows NT 6.1|User-Agent:.+Windows 7

 

You could also probably using something like Fiddler to inspect the http headers also and get the string from there.

Just tried this and got a false positive from a Windows 10 machine

@SteveO808,

User-Agent strings can be set separately and aren't absolute indications that the machine is running Windows 7. Running things in compatibility mode for instance can change the User-Agent string automatically. It's likely that this is a "false positive" in the sense that the machine isn't running Windows 7, but it was sending the User-Agent string associated with Windows 7.
