Red Condor Detects Sophisticated One-Two Punch Malware Campaign
Scammers using spoofed brands, social engineering, and phishing tactics to distribute malware on PCs via drive-by download
Rohnert Park, Calif. – June 9, 2010 – Red Condor today issued a warning of a new sophisticated email malware threat that spoofs YouTube and uses a redirect on a compromised website to a common Canadian Pharmacy web site to distribute malicious PDFs via drive-by download. The pharmacy page is actually a red herring that has distracted many security researchers from the true motive of these campaigns, a stealth drive-by download. With a single click, users can infect their computers.

The malware, which as of the morning of June 9, 2010 had not been detected by any anti-virus engines, comes in the form of a malicious PDF download. Red Condor has captured 10 versions of the malicious PDF, which likely exploits vulnerabilities in Adobe Acrobat. The campaign appears to be part of a much larger attack first detected by Red Condor several weeks ago (see Red Condor blog entry April 23, 2010) and has also recently spoofed Facebook and Twitter, among other popular brands. As unsuspecting users wait for what they believe is a YouTube or Twitter friend request, a greeting card, or even a Facebook login page to load, their browsers download and execute the malicious code, and then the Canadian Pharmacy page appears.
“The amount of effort behind these new campaigns is not commensurate with the typical Canadian Pharmacy spam campaigns that we have seen in the past. It’s the primary reason we started to suspect weeks ago that these campaigns have an ulterior motive and are more than just a series of mundane Canadian Pharmacy spam,” said Dr. Thomas Steding, CEO of Red Condor. “After analyzing this threat over the past several weeks, we now believe that this malicious drive-by downloading may be a new trend; a double-purposing spam campaign, or a twist on the blended threat spectrum of attacks we have seen so prevalent in the past year. Spammers are starting to use social engineering hooks, including those common with phishing attacks, which will generate clicks. If users click on the spam link, there is an opportunity for a sale and to steal their identities while infecting their computers – a sophisticated one-two punch.”
An interesting feature of this malware campaign is the distribution points appear to actively take measures to make researching the exploits difficult. The malware is served only if it thinks it can infect, and even then only upon the first request. Subsequent, identical requests from the same IP address do not result in the malware download. This level of intelligence and effort prevents traditional email security solutions, which rely on only automated detection methods from stopping the threat. Red Condor’s email security experts monitor for and analyze new threats twenty-four hours a day, seven days a week.
