Действия
Будучи активированным, червь создает семафор «COKE_DESTROYS_YOUR_BRAIN_5,», чтобы избежать повторного инфицирования своими копиями системы. Далее он помещает в системную директорию Windows (в Windows 9x и Windows ME это C:\\Windows\\System, в Windows NT/2000 это C:\\WINNT\\System32, в Windows XP это C:\\Windows\\System32) свою копию WinShellb.exe и вносит изменения в
реестровую запись
HKLM\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon\\
Shell = \"Explorer.exe WinShellb.exe\"
что обеспечивает его запуск при каждом начале работы пользователя в Windows.
В корневой директории диска C:\\ червь создает текстовый файл coke.txt, в котором содержится послание авторам червей Netsky, Beagle, Mydoom.
