Compromised Web Servers Serving Fake Flash Players

The tactic of abusing web servers whose vulnerable web applications allow a malicious attacker to locally host a malicious campaign is nothing new. In fact, malicious attackers have been building so much confidence in this risk-forwarding process of hosting their campaigns, that they would start actively spamming the links residing within low-profile legitimate sites across the web.



This campaign serving fake flash players is getting so prevalent these days due to the multiple spamming approaches used, that it's hard not to notice it - and expose it. From a strategic perspective, having a legitimate low-profile site -- of course with the obvious exceptions being on purposely registered for malicious purposes within the participating sites -- hosting your malicious campaign is pretty creative in terms of forwarding the responsibility, and the eventual blocking of a legitimate site to the its owner. As far as the owner's are concerned, it appears that some of them are already seeing the malware page popping-up on the top of their daily traffic stats, and have taken measures to remove it.



Moreover, Adobe's Product Security Incident Response Team (PSIRT) issued a warning notice about the attack yesterday, which could come handy if the attackers weren't taking advantage of client-side vulnerabilities, putting the unware end user is a situation where he wouldn't even receive a download dialog :



"We have seen coverage from the security community of a worm on popular social networking sites that is using social engineering lures to get users to install a piece of malware. According to the reports, the worm posts comments on these sites that include links to a fake site. If the link is followed, users are told they need to update their Flash Player. The installer, posted on a malicious site, of course installs malware instead of Flash Player.We’d like to take this opportunity to reiterate the importance of validating installers and updates before installing them. First off, do not download Flash Player from a site other than adobe.com – you can find the link for downloading Flash Player here. This goes for any piece of software (Reader, Windows Media Player, Quicktime, etc.) – if you get a notice to update, it’s not a bad idea to go directly to the site of the software vendor and download the update directly from the source. If the download is from an unfamiliar URL or an IP address, you should be suspicious."



The structure of the malware campaign is pretty static, with several exceptions where they also take advange of client-side vulnerabilities (Real player exploit) attempting to automatically deliver the fake flash update or player depending on the campaign. On each and every site, there are dnd.js and master.js scripts shich serve the rogue download window, and another .html file, where an IFRAME attempts to access the traffic management command and control, in a random URL it was 207.10.234.217/cgi-bin/index.cgi?user200. A sample list of participating URLs, most of which are still active and running :

The bottom line - over a thousand domains are participating, with many other apparently joining the party proportionally with the web site owner's actions to get rid of the malware campaign hosted on their servers.
