# Captura de hashes en red

<h2 align="center">Identificación de uso NTLM</h2>

### Visualización de eventos

Para identificar si NTLM está en uso, se puede realizar sin necesidad de tener privilegios de admin leyendo los eventos. En el campo de "Paquete de autenticación" se indicará si fue con Kerberos o NTLM:

```
wevtutil qe Security /q:"*[System[(EventID=4624)]]" /c:5 /f:text
```

### Sniffing con wireshark

Filtrar por:

```
ntlmssp
```

Si no se captura ninguna en el momento de realizarlo, se puede forzar de forma manual con:

```powershell
net use \\DC01\IPC$ /user:OILCORP\usuario password123
```
