Fake MP3s Running Rampant

Detection of a trojan named Downloader-UA.h was added to the McAfee DAT files several days ago. Since that time more than 360,000 McAfee VirusScan Online users have reported detections, a whopping 32% of those reporting in the past 24 hours alone. Now Downloader-UA.h is not your everyday trojan, this detection covers fake music and video files associated with fastmp3player.com.

When a user attempts to load one of these MP3 and MPG files, they don?t get the music/video they were hoping for; instead they?re directed to download a file named PLAY_MP3.exe. In fact, the MP3/MPG file they downloaded was completely fake, playing no media clip what so ever.

Here are some of the samples names that we?ve seen. Many many other file names are surely floating around on P2P networks. File sizes vary as these files are padded with nulls.

If users agree to download and run PLAY_MP3.exe (detected as Generic PUP.a with McAfee DAT files) a 4,800 word EULA is displayed.


Notable parts of the EULA include:

(3) The Licensed Materials you install will also include/be bundled with the following 3rd Party software products:

PRODUCT Mirar AND EULA http://policy.getmirar.com/

And my favorite:

22. Effective: January 14, 2007.

END OF DOCUMENT

NetNucleus Privacy Policy/EULA
This End User License Agreement (the ?Agreement?) is a legal agreement between you and NetNucleus Corp.

Does END OF DOCUMENT mean you can ignore the rest? Gotta love it when a ?vendor? expects their ?customers? to read a EULA that they themselves did not seem to read!

If you agree to the EULA and choose to proceed, Adware ?FBrowsingAdvisor? and ?SurfingEnhancer? is installed as described in the EULA. I especially like the directory named used by the developer:

c:\Documents and Settings\tani\My Documents\Dreamsoft\Firefox\firefox_adware\FF-Source\Source\Release\XPCOMEvents.pdb

If Firefox is not installed users may see an error message:



PlayMP3.exe from PlayMP3z.biz is installed, which is simply a browser control wrapped in an exe, and doesn?t actually play local MP3 files, but rather loads a webpage running the Wimpy MP3 Flash player. This page lets the user listen to a canned selection of a couple dozen songs.

In the end you?re left with a fake MP3 file taking up space, a worthless MP3 player, adware that claims not only to not display popups, but also to block them, and more adware that successfully displays popup and popunder ads.
