W32.Craq is a worm that circulates through removable drives using the potentially malicious files. W32.Craq may open a back door and steal information on the affected computer system. When executed, W32.Craq creates the potentially malicious files. W32.Craq then creates the registry entries. W32.Craq searches for executable files in the %ProgramFiles% and %UserProfile%/Application Data/ directories and the subfolders within the certain directories. W32.Craq then creates the copies of itself using the file name of the executable files that it finds under the certain format. W32.Craq then connects to one of several remote locations. W32.Craq may execute the potentially malicious actions on the targeted computer system such as display PNG files, log keystrokes, capture screenshots, undertake FTP operations, send emails, search for keywords in files, gather clipboard content and information on open windows, close windows and stop processes and restart the PC.
