As it happens, Carrie L Tolstedt is a real executive... at Wells Fargo. The lady in the picture is another Wells Fargo employee entirely.

But anyway, this is a simple forgery containing a link to a file at Cubby which downloads as Documents_JP3922PV8.zip and contains a malicious file Documents_JP3922PV8.exe which has a icon to make it look like an Adobe acrobat file.

The executable has a low VirusTotal detection rate of 3/57.  Various automated analysis tools [1] [2] [3] [4] show the malware downloading additional components from:


It then attempts to POST data to an IP at (Vsevnet Ltd. Russia) which is a critical IP to block if you want to protect yourself against this type of Upatre / Dyre attack.

The Malwr report also shows that amongst other things it downloads an executable lwxzqrk36.exe which has a detection rate of just 2/57. That Malwr report also shows that it downloads and pops up a PDF about drone strikes.

Presumably this PDF pops up to make the victim think that they have been duped into opening some politically-themed spam. Instead, they have actually installed the Dyre banking trojan.. in other words, the victim may well think that it is nothing serious when it really is.

The download locations for this Upatre/Dyre combination change all the time, but the IP address of  has been around for a little while. Also, it is a characteristic of this malware that it calls out to checkip.dyndns.org to determine the client IP address.. monitoring for traffic going to that location can be a useful indicator of infection.
