When you click the link it takes you to a page with a javascript download trigger and a redirect to efax.com or similar.
In my case it served me “wav_voice01829479-20150113.zip” which contained “wav_voice01829479-20150113.scr” – VirusTotal Report / Malwr Report

evoice junk

When you run the file it loads, waits a few seconds, creates a copy of itself and then loads a command prompt and quits itself.

cmd /D /R ping -n 10 localhost && del “C:\Users\derp\Desktop\wav_voice01829479-20150113.scr” && start /B “” “C:\Users\derp\AppData\Roaming\Windows\winlogin.exe” && exit

This command removes the file that the user runs and runs it’s own new copy. It also adds itself to the User (and possibly system, if running as an admin user) Run key in the registry.
It instantly then uses https://api.ipify.org to fetch the current IP address of the infected system.

tor2web.org is then being used to contact the CnC server, currently failing or blocked (https://ho7rcj6wucosa5bu.tor2web.org/gate.php):

<p>Access to this Hidden Service has been completely blocked</p><br />
<p>It may happen that Tor2web maintainers have to block proxy access to certain explicit illegal contents in order to keep the network up and running. In such case you can still access the content directly by using Tor, that’s because Tor2web just acts as a proxy server and the content is on a Tor Hidden Service.</p>
