Striking email subjects get the job done. Well, given another spamming operation that uses popular personalities and events, that seems to be the case. Using a variety of subject-body combinations (a lot of which are totally unrelated to each other!), these spammed messages again appeal to the curious mind, offering a link in the email body that would seem to provide more details.
TrendLabs’ Advanced Threats Researcher Joey Costoya says these messages lead users to an R.HTML Web page that also poses as an imitation of adult video-sharing site PornTube. The said page hosts the file VIDEO.EXE. We’ve seen this type of attack before in another spam run that also used pop culture as bait.
In this screenshot we see the upcoming Beijing Olympics being used to trick fans and those curious enough about the event to click the URL:

and email body, possibly the result of using spam templates.
There are several of these VIDEO.EXE URLs, and some of the detections we have seen so far include:
The Trend Micro Smart Protection Network already blocks the spam messages using this trick, and likewise blocks all related malicious URLs, so Trend Micro users are protected from downloading the Trojans. Since the download locations can be updated anytime (today a user may download TROJ_ZLOB.GBA, but tomorrow it might be an entirely new malware), only a multi-layered protection allows users to rest easy.
