CNN Lends Authenticity to News Spam

UPDATED!

At the UAB Spam Data Mine we've been tracking the recent malware attacks which use news headlines as their spam bait. You've seen a few previous stories on the subject in this blog, NuWar Looks for News Readers, News Headlines Still Out of Control, and Top News in Spam Old News.

The thing that makes last night's new spam campaign newsworthy is the inclusion of a very authentic looking CNN wrapper on the spam.



We received more than 1,400 copies of this spam email so far in the UAB Spam Data Mine. While the subject of the email has always been "CNN.com Daily Top 10", the listed stories are composed of a random mix from the following 84 topics:

UPDATE: Now we're seeing "/news/" as a valid path, instead of the earlier "/index2.html". We'll keep an eye out on this trend . . . so far there is not actually any content on these "/news/" pages, however they are all currently resolving to the same IP. Perhaps the spammer just got ahead of himself?

Sites are hosted around the world, including the United States, Brasil, France, Italy, and Poland. Analysis of the malware and the websites by UAB students shows that it is clearly related to previous "news" campaigns, though you'll forgive me if we don't share all of those details here.

As before, malware detection is far from complete in the anti-virus community. A scan of this malware on VirusTotal still shows only 16 of 36 different detect the virus, although I'm happy to report that Symantec is now among those who do. (McAfee, Trend, and Microsoft are still among those who do not.)

The challenge to those wishing to block the virus is the same as we've been dealing with. The current malware name is "get_flash_update.exe", but even blocking by name may not be adequate. One of the website tricks is to cause machines to download the malware via a javascript program. In the javascript program, the name of the file is interspersed with "garbage characters", which are then removed by the program when it comes time to save the file.

For example:

g(e(t_f&l*a^s#h_$u!p*(date)#.!%e^x&#e!'

is followed by a command to remove:

replace(/\!|@|#|\$|%|\^|&|\*|\(|\)

which leads to the name to be stored being:

get_flash_update.exe

The actual filename then, would never occur in the web filters.

These viruses are on legitimate websites which have been compromised. Blocking the websites will protect your business, but may block a real company as penalty for their compromise. We are still working with webmasters and providers to learn how the sites are being compromised, but the leading theory at the moment is via an FTP password compromise.
