Attempted Malvertising on KrebsOnSecurity.com

Members of an exclusive underground hacker forum recently sought to plant malware on KrebsOnSecurity.com, by paying to run tainted advertisements through the site’s advertising network — Federated Media. The attack was unsuccessful thanks to a variety of safeguards, but it highlights the challenges that many organizations face in combating the growing scourge of “malvertising.”

Last week, I listed the various ways this blog and its author has been “honored” over the past few years by the cybercrime community, but I neglected to mention one recent incident: On May 27, 2011, several hackers who belong to a closely guarded English-language criminal forum called Darkode.com sought to fraudulently place a rogue ad on KrebsOnSecurity.com. The ad was made to appear as though it was advertising BitDefender antivirus software.

The miscreants agreed to pay at least $272 for up to 10,000 impressions of the ad to be run on my site. Fortunately, I have the opportunity to review ads that come through Federated’s system. What’s more, Federated blocked the ad before it was even tagged for approval.

Darkode members plot to purchase a rogue ad on KrebsOnSecurity.com. They failed.

I learned about this little stunt roughly at the same time it was being planned; Much to the constant annoyance of the site administrators, I secretly had gained access to Darkode and was able to take this screen shot of the discussion. The incident came just a few weeks after I Tweeted evidence of my presence on Darkode by posting screenshots of the forum. The main administrator of Darkode, a hacker who uses the nickname “Mafi,” didn’t appreciate that, and promised he and his friends had something fun planned for me. I guess this was it. Interestingly, Mafi also is admin at malwareview.com and is the developer of the Crimepack exploit kit.
