The EXE-in-ZIP spam storm continues

Two more EXE-in-ZIP spams.. the first is a terse one with a subject "Voice Message from Unknown Caller" or "Voicemail Message from unknown number" not much else with a malicious EXE-in-ZIP (VoiceMessage.zip) attachment with VirusTotal score of 7/46 which calls home [1] [2] [3] to amandas-designs.com on (012 Smile Communications Ltd., Israel)

The second one is a fake Wells Fargo spam similar to this:

In this case the EXE-in-ZIP attachment (BankDocs.zip) has a VirusTotal detection rate of 14/47 and calls home [4] [5] [6]  to kidgrandy.com on (Singlehop, US).

Given the massive onslaught of EXE-in-ZIP spam, I would strongly recommend blocking ZIP files with executables in them at the perimeter.
