Checking Credentials (Domain)

Authentication

• Failed logins result in a [-]
• Successful logins result in a [+] Domain\Username:Password

{% hint style="info" %}
Code execution results in a (Pwn3d!) added after the login confirmation. With SMB protocol, most likely your compromised user is in the local administrators group.
{% endhint %}

    SMB         <target>    445    HOSTNAME          [+] <domain>\<username>:<password> (Pwn3d!)

The following checks will attempt authentication to the entire /24 though a single target may also be used.

{% hint style="warning" %}
If NTLM authentication is not available, Kerberos requires the hostname and domain name instead of an IP address.
{% endhint %}

nxc smb <target> -u <username> -p <password>

nxc smb <target> -u <username> -H <nt-hash>
nxc smb <target> -u Administrator -H <nt-hash>
nxc smb <target> -u Administrator -H <ntlm-hash>
