OVERVIEW
Modifica archivos para impedir la ejecución correcta de programas y aplicaciones. Elimina archivos para impedir la ejecución correcta de programas y aplicaciones.
Este malware se elimina tras la ejecución.
TECHNICAL DETAILS
Instalación
Crea las carpetas siguientes:
- %System Root%\ProgramData\Microsoft
- %System Root%\ProgramData\Microsoft\Windows
- D:\RECYCLER
- %System Root%\RECYCLER
(Nota: %System Root% es la carpeta raíz, normalmente C:\. También es la ubicación del sistema operativo).
)Técnica de inicio automático

HKEY_LOCAL_MACHINE\SysTEM\cURrentcontrolsEt\
sErvices\UPNPSysapp
HKEY_LOCAL_MACHINE\SysTEM\cURrentcontrolsEt\
sErvices\UDPServ
HKEY_LOCAL_MACHINE\SysTEM\cURrentcontrolsEt\
sErvices\RegServ
HKEY_LOCAL_MACHINE\SysTEM\cURrentcontrolsEt\
sErvices\RegLog0n
HKEY_LOCAL_MACHINE\SysTEM\cURrentcontrolsEt\
sErvices\RegMon
HKEY_LOCAL_MACHINE\SysTEM\cURrentcontrolsEt\
sErvices\DNSMon
Otras modificaciones del sistema
Modifica los archivos siguientes:
- %User Profile%\Application Data\Microsoft
(Nota: %User Profile% es la carpeta de perfil del usuario activo, que en el caso de Windows 98 y ME suele estar en C:\Windows\Profiles\{nombre de usuario}, en el caso de Windows NT en C:\WINNT\Profiles\{nombre de usuario} y en el caso de Windows 2000, XP y Server 2003 en C:\Documents and Settings\{nombre de usuario}).
