Anonymous Internet access after installed Template for CitrixXenApp

New Member

Recently, we've received suspicious Internet sites access (see below sites) attempts on server installed after installed the Template for Citrix XenApp. I'd like to know is it possible to eliminate it and how can I fix it. Many thanks!

You can run the PowerShell scripts from the command line outside of Splunk to see if anything is wrong there. Also, make sure something hasn't hijacked the actual .ps1 files in

SPLUNK_HOME\etc\apps\TA-XA6x-Server\bin\powershell

You can also compare what you have to the source located at:
https://github.com/splunk/splunk-template-xenapp/tree/master/app/TA-XA6x-Server/bin/powershell

Where are you seeing this (as in what log or Splunk query)?

There isn't anything in the Template for XenApp that would cause this.

We've seen it on the firewall log and the Internet access attempts stopped after we add the %splunkhomefolder%\etc\apps\TA-XA6x-Server\local\app.conf and with the statement "state = disabled". The Internet access attempts resume right after I change the statement to "state = enabled". And I can see the attempts are generated by Powershell.exe via port 80. Any clues? Many thanks!
