citizensbank.com "Issue File I3774 Processed" spam

For some reason I'm seeing a lot of these EXE-in-ZIP attacks recently. Here's another one with a malicious attachment:

There is a malicious attachment called issue_report_I3774.zip which in turn contains an executable file issue_report_I6576543219672.exe which has a detection rate of 12/47 at VirusTotal. Automated analysis [1] [2] [3] shows some of the mechanics of the malware, including network communications with wptutes.com on 74.221.210.124 (DME Hosting LLC, US).

Recent experience with this type of attack shows that when one domain on a sever is compromised, then they all are. If you want to block everything then the following domains appear to be on that server:

2ndry.com
bar-stool.info
electric-wheelchair.info
freeb4u.com
gov-l.net
hot-buys.org
hot-water.org
iconsumers.org
leather-handbags.info
storage-cabinets.info
thesafeconsumer.com

QuickBooks spam / Invoice_20130912.zip

This fake QuickBooks spam has a malicious attachment:

Date:      Thu, 12 Sep 2013 20:29:17 +0200 [14:29:17 EDT]
From:      QuickBooks Invoice [auto-invoice@quickbooks.com]
Subject:      Important - Payment Overdue

The information contained in this message may be privileged, confidential and protected from disclosure. If the reader of this message is not the intended recipient, or an employee or agent responsible for delivering this message to the intended recipient, you are hereby notified that any dissemination, distribution or copying of this communication is strictly prohibited. If you have received this communication in error, please notify your representative immediately and delete this message from your computer. Thank you. 
The attachment is Invoice_20130912.zip which in turn contains a malicious executable Invoice_20130912.exe (note the date is encoded into the filename). The detection rate at VirusTotal is just 3/46.

Automated analysis [1] [2] [3] [4] shows that amongst other things, the file attempt to communicate with the domain leightongriffiths.com on an apparently compromised server at 64.50.166.122 which has been seen before.

Given that there are now several domains serving malware on the same server [1] [2] it is probably safe to assume that all the domains on that server are malicious and should be blocked.

There is an attachment Label_FOHWXR30ZZ0LNB1.zip which in turn contains an executable Label_368_09112013_JDSL.exe which has a very low detection rate at VirusTotal of just 2/47. Automated analysis [1] [2] [3] shows an attempted connection to a hijacked domain drippingstrawberry.com hosted on 64.50.166.122 (LunarPages, US) with quite a lot of other hijacked domains. Blocking or monitoring traffic to this IP could stop the infection

URLquery shows the following domains are distributing malware on that server:
cardiffpower.com
celebrategoodtimes.com
drippingstrawberry.com

thisisyourwife.co.uk

For the record, the following domains appear to be on that server. They all look legitimate, but some others may be hijacked (and others may not be). Do with this list what you will:
