Asimismo, genera dos ficheros ocultos en el directorio Windows\System:
explore.exe (24,064 bytes)
SMTP.ocx (25,737 bytes)
Genera una clave en el registro de sistema para cargarse en cada inicio:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run "Explore" = C:\WINDOWS\SYSTEM\EXPLORE.exe
Propagación a través de red
Se copia en el directorio Windows\system utilizando los mismos nombres de la lista de adjuntos y modifica la configuración de KaZaa para que utilice Windows\System como carpeta compartida por defecto.
Activación
Para la activación, el gusano genera un contador en el registro de sistema
HKEY_CURRENT_USER\DeathTime = %Run count%
si el contador supera el valor de 30 ejecuciones, el gusano intentará borrar todos los ficheros de datos del sistema, presentando secuencialmente las siguientes cajas de mensaje:
al pulsar OK en la última el sistema se reinicia.
Eliminación
El gusano se controla desde los DAT
arriba indicados (mínimo 4267). Para detener el proceso en memoria del gusano, y
eliminar ficheros y claves de registro creadas, pueden ejecutar nuestra utilidad EliHolaA
