# 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.

### **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.
