How, from where, by which IP you got infected w/FakeAV: System Progressive Protection; UPS Fake Spam, Spain's Front End Infector+Support Page, and Taiwan's CnC server

24 Nov 2012 Today I was receiving report of another UPS spam (again, thank's to officer Pryor). Which lead users to download the FakeAV System Progressive Protection. This investigation is exposing all aspect of infection, from which spam, what downloaded trojan downloader used, which CnC used for communication and down to the support page.

Infection Summary

1. Drive by spam
2. w/html URL to h00p://proyectosnavarra.es/CMUNFWKUWY.html ←Troj/Downloader's dropper
3. Trojan Download FakeAV installer from IPs`: 217.76.130.213 (Spain), 
   59.126.131.132 (Taiwan), 61.222.241.208 (Taiwan) & 217.76.130.3 (Spain)
4. Send data to these IP: 59.126.131.132, 61.222.241.208 (Taiwan)
5. Support Center is in this IP: 178.32.29.188 (Spain)

All of the data written is as per it is, for the law evidence & research purpose I also share the samples and captures. I am so sorry for taking so long analyzing this, since I have only one windows machine to perform all of this analysis.

Here we go.. 

Following another reported UPS email like below...

Which lead us to the link:

One thing I LOVE of spam infection is we can fetch it well...
