sekurlsa::tickets lists Kerberos tickets belonging to all authenticated users on the target server/workstation. Unlike kerberos::list, sekurlsa uses memory reading and is not subject to key export restrictions. Sekurlsa can also access tickets of others sessions (users). It has the following command line argument:

  • /export: tickets are exported in .kirbi files. They start with user's LUID and group number (0 = TGS, 1 = client ticket(?) and 2 = TGT). The tickets are saved in the current directory.

{% hint style="warning" %} This command requires elevated privileges (by previously running privilege::debug or by executing Mimikatz as the NT-AUTHORITY\SYSTEM account). {% endhint %}
