The attachment is in the format Loan.recipient-name.zip and contains the executable Loan_08082013.exe (note the date is encoded into the filename).
The initial file is just a trojan downloader. VirusTotal results are 10/45. The Malwr analysis gives some excellent details of what is going in, included attempted downloads from the following locations:
[donotclick]www.arki.com/ponyb/gate.php
[donotclick]ftp.miniaturesbykim.com/fzKU1Y.exe
[donotclick]www.gfchargers.org/iwa4s1.exe
[donotclick]ftp.jason-tooling.com/nhdx.exe
[donotclick]www.rachelcondry.com/nLiZVHtr.exe
This downloads a Zeus variant with a very low detection rate of 4/45. The Malwr analysis for this part shows some apparent peer-to-peer traffic (note some of these IPs are legitimate and belong to Google):
