Date: Fri, 23 Aug 2013 09:43:44 -0500 [10:43:44 EDT]In this case there is an attachment WellsFargo.victimname.zip which contains a malicious executable WellsFargo_08232013.exe (note the date is encoded into the filename). The VirusTotal detection rate is just 4/45, but the file itself is unusually small (just 21Kb unzipped, 8Kb zipped) when I would normally expect to see the executable closer to 100Kb for this sort of malware.
Please review attached documents.

What does it do? Well, the automated reports show it rummaging through various browser and address book data, and the ThreatTrack report [pdf] shows a DNS lookup of the domain huyontop.com plus what appears to be some peer-to-peer activity. Malwr, Comodo CAMAS and Anubis are somewhat less enlightening.
The WHOIS details for the domain huyontop.com appear to be valid (I won't list them here, look them up if you want), however it was only registered a few days ago. I can't tell you exactly what it is doing, but I would treat huyontop.com as being potentially malicious and block it if you can.
