Technical Details



Variant:Logo.A

Once the user has visited in a web page that contains the trojan, it installs itself to the Windows startup directory as "logo.hta". After that it will be executed when the system is restarted.

When the "logo.hta" is executed, the trojan adds four links to user's Favorites directory and replaces the Internet Explorer start page with a link to an adult site.

Links added to Favorites directory are labeled as follows:


The River Belle Casino, where Lady Luck smiles on you!

 Send free cards to your friends at nicecards!

 Real money in your pocket!

 Welcome to Adult Friend Finder! 	 	

Finally the trojan removes itself from the startup directory.


Variant:Logo.B

This variant does not alter the Internet Explorer start page, and the links added to Favorites directory are somewhat different:
