Especially in big Windows shops, where the only Macs might be a handful in the graphic design department, it’s easy for non-standard machines to fall through the cracks when it comes to patching and managing software.Second, please please please restrict your Microsoft Federation settings. Change the $target variable to point at the user you are targeting.Now, navigate to the location of the PowerShell script and run it.You should see a prompt appear on the target machine, and the URL should open in a new browser window!What can you do?

At highest risk are those organizations that have Microsoft’s Federation enabled, allowing external entities to communicate with their users via Skype/Lync.A forced browsing exploit + browser or file-format exploit + open federation = super spear-phishing.
