Avid readers of this blog can attest that we’ve been writing about FakeRean for, oh, quite a number of months now. In case you missed out on those posts or you no longer remember them, I have for you here a short list of what we’ve written about this rogue AV family so far:
- What’s in a (rogue) name? VirusTotal 2010
- Malicious warez site offers Firefox 4.0 beta download scam
- Rogue downloads look real: read the fine print
- Obama, birth certificates, and Rogue AV
FakeRean is initially discovered by Microsoft a couple of years ago. Like all rogue AV families, it displays fake scanning results to users in an effort to dupe them into coughing up cash in order to register the software and clean their systems supposedly. This family also alters the infected system’s registry quite extensively and drops lots of component and shortcut files, among other things. What sets FakeRean apart from the usual rogues is its ability to hijack a file association for executable (.EXE) files, which allows it to reappear every time an application is run.
Our intrepid rogue AV hunter, Patrick Jordan, spotted new ways on how FakeRean is currently being distributed online, and by the looks of things, the bad guys behind it have not only casted a wider net but also went, erm, hard-core. Case in point:

The above page is found on SourceForge.net, a prominent repository of open-source software, as a profile page. Of course, it wouldn’t matter whether you’re 18 or not, you still get a free but malicious software to download and run on your systems once you click any of the buttons there. This software is a PDF exploit that, once installed, drops and also installs FakeRean. We detect the exploit as Exploit.PDF-JS.Gen (v).

We advise Internet users to be careful when clicking image and text links online. Be extra careful, if not steer clear all together, when visiting online profiles hosted on any site that look suspicious.
