Every super hero has an arch nemesis. For a lot of Threat Researchers, including myself, Rogue Security Products, or better known as FakeAV, is theirs. Back in the day when I was primarily a PC malware fighter, FakeAV was a prevalent threat that was always coming up with new ways to infect users nearly every other day. I knew it was only a matter of time that the same malware authors would turn mobile. I am afraid those days are upon us. How could I ever forget such an identifiable logo:
“Android Security Suite Premium”… yeah, right! This spy which is being called Android.FakeSecSuit retrieves incoming sms messages, extracts the phone number and message, and then sends the stolen info off:
As you can see in the GET command from the PCAP, highlighted in blue is the phone number and message I sent to my test phone now being sent off to a site.
Now that the developers of the popular FakeAV malware have entered into the mobile world expect to to see a lot more variations of this… and if they follow the same pattern as they did in the PC world, I mean A LOT! We are seeing it in Torrents and/or alternative markets. Remember, when downloading Android apps choose them wisely and download from a trusted source. Check reviews, research the developer and verify permissions requested before downloading. And of course, scan with Webroot SecureAnywhere Mobile.

On their way to convert legitimate traffic into malware-infected hosts using web malware exploitation kits, cybercriminals have been actively experimenting with multiple traffic acquisition techniques over the past couple of years. From malvertising (the process of displaying malicious ads), to compromised high-trafficked web sites, to blackhat SEO (search engine optimization), the tools in their arsenal have been systematically maturing to become today’s sophisticated traffic acquisition platforms delivering millions of unique visits from across the world, to the cybercriminals behind the campaigns.
What are some of the latest campaigns currently circulating in the wild? How are cybercriminals monetizing the hijacked traffic? Are they basically redirecting to the landing page of an affiliate network, earning revenue in the process, or are they serving malicious software to unsuspecting and gullible end and corporate users?
Let’s find out by profiling a currently active blackhat SEO (search engine optimization) campaign at the popular document sharing web site Scribd, currently using double monetization of the anticipated traffic, namely, redirecting users to a dating affiliate network, and serving malware in between.
