If you click on the link (not advisable) you get the following page (hosted on a botnet somewhere):



You are then prompted to install and run a file called Adobemedia10.exe at which things will start to go seriously wrong.

The VirusTotal report indicates a very low detection rate for the binary (VBA32 flags it up as Embedded.Rootkit.Win32.Agent.ex). However, the ThreatExpert prognosis shows just how much damage this does, and identifies a C&C server at 58.65.232.17 which is a well-known malware server hosted by black hat hosting outfit Hostfresh.

This looks like a fairly horrible thing to try to clean up, and probably best to recover data, reformat and reinstall.

"Classmates Info Center": Currently planning the 2009 Year Reunion

There's a fake "Classmates" email being spammed out, that leads to a fake video that needs a fake "Adoble Media Player" called Adobe_Player10.exe and as you would probably guess, at the end of all this fakery is a nasty trojan.

The landing page looks like this:


Detection rates are poor according to VirusTotal. ThreatExpert's report is right here. It installs a rootkit and does all sorts of nasty things. Avoid.
