And I *know* a lot.  It is known for hooking into IE through BHO and Winlogon via 
Winlogon\Notify and more recently via the Local Security Authority Subsystem Service.  And 
I know its intial infection vector was through Java Exploits.  I remember when they first

read where Dustin was an employee of Malwarebytes.  Dustin and I were both employee 
Malware Researchers for Malwarebytes  :-)
