Total Secure 2009 and Google search poisoning

Total Secure 2009 is one of the new batch rogue security applications. The installer of Total Secure 2009 generally masquerades itself as a fake codec (Zlob!) and gets registered as a BHO for Internet Explorer. Here's a HijackThis entry for one of such BHO:

O2 - BHO: Apaps - {EC748705-E0FD-4671-9AFF-890579E57450} - C:\WINDOWS\system32\gaspt.dll

This BHO poisons the Google search results, so that first few results are always redirected to Total Secure 2009 download links. Here's an example of search result poisoning by Total Secure 2009 dropper:

You can follow the steps given here to get rid of this malware.

AntiVirus 2009 updates

Here's one more site pushing AntiVirus 2009 rogue security software:

AntiVirus 2009 replaces the actual Windows Security Center applet in Control Panel with a fake version, which contains links to dubious websites. This Control Panel applet is named as scui.cpl, whereas the original applet is named wscui.cpl. See if you can spot the not in the below screenshots ;)

PrivateContent and fake Google Toolbar BHO

The gang behind rogue security software has taken new approach to peddle malware. Instead of fake codecs, now they are offering some kind of "Access Code Generator" called PrivateContent, using which one can supposedly access online videos. Obviously, this access code generator is a fake!

PrivateContent.exe is hosted at and is not very well detected as of now. Here's the VirusTotal scan result (complete scan results can be found here):

File PrivateContent.exe
AntiVir - TR/Drop.Agent.vsu
Prevx1 V2 - Malicious Software
Webwasher-Gateway - Trojan.Drop.Agent.vsu

PrivateContent.exe drops a DLL named googletoolbar1.dll in %ProgramFiles%\Google\ directory. This DLL is registered as an Internet Explorer BHO. HijackThis entry for this BHO is as shown below:

O2 - BHO: Google Toolbar Helper - {AA58ED58-01DD-4D91-8333-CF10577473F7} - C:\Program Files\Google\googletoolbar1.dll

Surprisingly, this fake googletoolbar1.dll is not detected by any of the AVs at VirusTotal (scan results can be found here).

Googletoolbar1.dll generates popups/ads and tries to install rogue security software. Check out below screenshots which show fake googletoolbar1.dll in action!

The codec is named as Megazcodec and is hosted at Megazcodec is yet another Zlob/DNSChanger variant; however it is not well detected as of now. The VirusTotal report is as shown:

Windows Filtering Platform (WFP) user mode examples

So far, in Windows 2000/XP/2003 operating systems the packet filtering APIs (PfXxx APIs) were used to implement TCP/IP packet filtering applications and firewalls. However, these PfXxx APIs are discontinued in Windows Vista/2008! But, Vista contains a completely new filtering engine called Windows Filtering Platform (WFP). The WFP gives various APIs using which packet filtering can be achieved. I thought of writing a simple class which encapsulates these APIs. It might help if you are planning to use WFP APIs. The article can be found here. That article is just a starting point, and you can do much more things with WFP. These are some of the pages which give information about WFP:
WFP Management API Reference
WFP structures Reference
Windows SDK 2008
Visual Studio 2008
