Web Browser Home Page and Search Page Modification

This Worm modifies the Internet Explorer Zone Settings.

Other Details

This Worm connects to the following URL(s) to check for an Internet connection:

  • www.microsoft.com

It connects to the following possibly malicious URL:

  • {BLOCKED}.{BLOCKED}.31.18
  • {BLOCKED}elemetry.com

NOTES:

This worm drops shortcut files whose names correspond to the files and folders in the root directory of the removable drive then hides the original files and folders to trick users. When the shortcut files are double clicked, the dropped copy in {Removable Drive Letter}:\Drive\{random numbers} is executed.
