The email has been digitally signed by Dropbox (which means exactly nothing) and is spoofing the wholly legitimate Broad Oak Ltd who have been a target of this sort of thing
several times before.
In this case, the link in the email goes to:
https://www.dropbox.com/l/dFxVxjuDRo3j2oANVURy2v
and then to
https://www.dropbox.com/s/fnsprei93c45ts6/MT%20103_PO_NO!014.zip
Which leads to a malicious EXE file called
MT 103_PO_NO!014.zip. Inside that is the malware itself, a file
.pdf.scr which has a detection rate of
11/57. According to the
Malwr report it drops another executable with a detection rate of
9/57. The payload looks similar to the Zeus trojan.
Also, according to
Malwr and
ThreatExpertit attempts to communicate with an apparent web-to-Tor gateway at
mmc65z4xsgbcbazl.onion.am
onion.am is hosted on 37.220.35.39 (YISP Colo, Netherlands) and I suggest this isn't the sort of thing that you want on your corporate network regardless of its legitimate uses.
Be aware that there are probably many other Dropbox locations in use for this spam run. If you see more, I suggest you forward the email to
abuse -at- dropbox.com who are normally quite good at dealing with this sort of thing.
