• Modifies the Windows HOSTS file to prevent access to certain Internet sites, the majority of which are antivirus or security-related.
• Attempts ping attacks against certain Web sites, presumably to launch a form of denial of service (DoS) attack.
• Terminates applications or restarts Windows when the title of the active window contains certain strings, many of which may be representative of antivirus or system tools that might ordinarily be used to detect or remove the worm.
• Overwrites the autoexec.bat file with the word "pause", causing systems that employ the autoexec.bat file to pause on bootup. Some variants of Win32/Brontok may modify the autoexec.bat in order to display a message during bootup.
