Don't Detect Tools - Detect Techniques

Rationale behind releasing this software was outlined in an acompanying blog post:

ProtectMyTooling - Don't detect tools, detect techniques

Intro

Script that wraps around multitude of packers, protectors, obfuscators, shellcode loaders, encoders, generators to produce complex protected Red Team implants. Your perfect companion in Malware Development CI/CD pipeline, helping watermark your artifacts, collect IOCs, backdoor and more.

ProtectMyToolingGUI.py

With ProtectMyTooling you can quickly obfuscate your binaries without having to worry about clicking through all the Dialogs, interfaces, menus, creating projects to obfuscate a single binary, clicking through all the options available and wasting time about all that nonsense. It takes you straight to the point - to obfuscate your tool.

Aim is to offer the most convenient interface possible and allow to leverage a daisy-chain of multiple packers combined on a single binary.

That's right - we can launch ProtectMyTooling with several packers at once:

C:\> py ProtectMyTooling.py hyperion,upx mimikatz.exe mimikatz-obf.exe

The above example will firstly pass mimikatz.exe to the Hyperion for obfuscation, and then the result will be provided to UPX for compression. Resulting with UPX(Hyperion(file))

Features

Supports multiple different PE Packers, .NET Obfuscators, Shellcode Loaders/Builders
Allows daisy-chaining packers where output from a packer is passed to the consecutive one: callobf,hyperion,upx will produce artifact UPX(Hyperion(CallObf(file)))
Collects IOCs at every obfuscation step so that auditing & Blue Team requests can be satisfied
Offers functionality to inject custom Watermarks to resulting PE artifacts - in DOS Stub, Checksum, as a standalone PE Section, to file's Overlay
Comes up with a handy Cobalt Strike aggressor script bringing protected-upload and protected-execute-assembly commands
Straightforward command line usage

Installation

This tool was designed to work on Windows, as most packers natively target that platform.

Some features may work however on Linux just fine, nonetheless that support is not fully tested, please report bugs and issues.

First, disable your AV and add contrib directory to exclusions. That directory contains obfuscators, protectors which will get flagged by AV and removed.
Then clone this repository

PS C:\> git clone --recurse https://github.com/Binary-Offensive/ProtectMyTooling

Actual installation is straightforward:

Windows

PS C:\ProtectMyTooling> .\install.ps1

Linux

bash# ./install.sh

Gimmicks

For ScareCrow packer to run on Windows 10, there needs to be WSL installed and bash.exe available (in %PATH%). Then, in WSL one needs to have golang installed in version at least 1.16:

cmd> bash
bash$ sudo apt update ; sudo apt upgrade -y ; sudo apt install golang=2:1.18~3 -y

Configuration

To plug-in supported obfuscators, change default options or point ProtectMyTooling to your obfuscator executable path, you will need to adjust config\ProtectMyTooling.yaml configuration file.

There is also config\sample-full-config.yaml file containing all the available options for all the supported packers, serving as reference point.

Friendly reminder

If your produced binary crashes or doesn't run as expected - try using different packers chain.
Packers don't guarantee stability of produced binaries, therefore ProtectMyTooling cannot as well.
While chaining, carefully match output->input payload formats according to what consecutive packer expects.

Usage

Before ProtectMyTooling's first use, it is essential to adjust program's YAML configuration file ProtectMyTooling.yaml. The order of parameters processal is following:

Firstly default parameters are used
Then they're overwritten by values coming from YAML
Finally, whatever is provided in command line will overwrite corresponding values

There, supported packer paths and options shall be set to enable.

Scenario 1: Simple ConfuserEx obfuscation

Usage is very simple, all it takes is to pass the name of obfuscator to choose, input and output file paths:

C:\> py ProtectMyTooling.py confuserex Rubeus.exe Rubeus-obf.exe

Scenario 3: Complex malware obfuscation with watermarking and IOCs collection

Below use case takes beacon.exe on input and feeds it consecutively into CallObf -> UPX -> Hyperion packers.

Then it will inject specified fooobar watermark to the final generated output artifact's DOS Stub as well as modify that artifact's checksum with value 0xAABBCCDD.

Finally, ProtectMyTooling will capture all IOCs (md5, sha1, sha256, imphash, and other metadata) and save them in auxiliary CSV file. That file can be used for IOC matching as engagement unfolds.

Above are the packers that are supported, but that doesn't mean that you have them configured and ready to use. To prepare their usage, you must first supply necessary binaries to the contrib directory and then configure your YAML file accordingly.

RedWatermarker - built-in Artifact watermarking

Artifact watermarking & IOC collection

This program is intended for professional Red Teams and is perfect to be used in a typical implant-development CI/CD pipeline. As a red teamer I'm always expected to deliver decent quality list of IOCs matching back to all of my implants as well as I find it essential to watermark all my implants for bookkeeping, attribution and traceability purposes.

To accommodate these requirements, ProtectMyTooling brings basic support for them.

Artifact Watermarking

ProtectMyTooling can apply watermarks after obfuscation rounds simply by using --watermark option.:

py ProtectMyTooling [...] -w dos-stub=fooooobar -w checksum=0xaabbccdd -w section=.coco,ALLYOURBASEAREBELONG

There is also a standalone approach, included in RedWatermarker.py script.

It takes executable artifact on input and accepts few parameters denoting where to inject a watermark and what value shall be inserted.

Example run will set PE Checksum to 0xAABBCCDD, inserts foooobar to PE file's DOS Stub (bytes containing This program cannot be run...), appends bazbazbaz to file's overlay and then create a new PE section named .coco append it to the end of file and fill that section with preset marker.

py RedWatermarker.py beacon-obf.exe -c 0xaabbccdd -t fooooobar -e bazbazbaz -s .coco,ALLYOURBASEAREBELONG

Full watermarker usage:

    Watermark thy implants, track them in VirusTotal
    Mariusz Banach / mgeeky '22, (@mariuszbit)
    <mb@binary-offensive.com>

usage: RedWatermarker.py [options] <infile>

options:
  -h, --help            show this help message and exit

Required arguments:
  infile                Input implant file

Optional arguments:
  -C, --check           Do not actually inject watermark. Check input file if it contains specified watermarks.
  -v, --verbose         Verbose mode.
  -d, --debug           Debug mode.
  -o PATH, --outfile PATH
                        Path where to save output file with watermark injected. If not given, will modify infile.

PE Executables Watermarking:
  -t STR, --dos-stub STR
                        Insert watermark into PE DOS Stub (This program cannot be run...).
  -c NUM, --checksum NUM
                        Preset PE checksum with this value (4 bytes). Must be number. Can start with 0x for hex value.
  -e STR, --overlay STR
                        Append watermark to the file's Overlay (at the end of the file).
  -s NAME,STR, --section NAME,STR
                        Append a new PE section named NAME and insert watermark there. Section name must be shorter than 8 characters. Section will be marked Read-Only, non-executable.

Currently only PE files watermarking is supported, but in the future Office documents and other formats are to be added as well.

IOCs Collection

IOCs may be collected by simply using -i option in ProtectMyTooling run.

They're being collected at the following phases:

on the input file
after each obfuscation round on an intermediary file
on the final output file

They will contain following fields saved in form of a CSV file:

timestamp
filename
author - formed as username@hostname
context - whether a record points to an input, output or intermediary file
comment - value adjusted by the user through -I value option
md5
sha1
sha256
imphash - PE Imports Hash, if available
(TODO) typeref_hash - .NET TypeRef Hash, if available

Resulting will be a CSV file named outfile-ioc.csv stored side by side to generated output artifact. That file is written in APPEND mode, meaning it will receive all subsequent IOCs.

RedBackdoorer - built-in PE Backdooring

ProtectMyTooling utilizes my own RedBackdoorer.py script which provides few methods for backdooring PE executables. Support comes as a dedicated packer named backdoor. Example usage:

Takes Cobalt Strike shellcode on input and encodes with SGN (Shikata Ga-Nai) then backdoors SysInternals DbgView64.exe then produces Amber EXE reflective loader

Backdooring options:
  -n NAME, --section-name NAME
                        If shellcode is to be injected into a new PE section, define that section name. Section name must not be longer than 7 characters. Default: .qcsw
  -i IOC, --ioc IOC     Append IOC watermark to injected shellcode to facilitate implant tracking.

Authenticode signature options:
  -r, --remove-signature
                        Remove PE Authenticode digital signature since its going to be invalidated anyway.

------------------

PE Backdooring <mode> consists of two comma-separated options.
First one denotes where to store shellcode, second how to run it:

<mode>

    save,run
      |   |
      |   +---------- 1 - change AddressOfEntryPoint
      |               2 - hijack branching instruction at Original Entry Point (jmp, call, ...)
      |               3 - setup TLS callback
      |
      +-------------- 1 - store shellcode in the middle of a code section
                      2 - append shellcode to the PE file in a new PE section
Example:

    py RedBackdoorer.py 1,2 beacon.bin putty.exe putty-infected.exe

Cobalt Strike Integration

There is also a script that integrates ProtectMyTooling.py used as a wrapper around configured PE/.NET Packers/Protectors in order to easily transform input executables into their protected and compressed output forms and then upload or use them from within CobaltStrike.

The idea is to have an automated process of protecting all of the uploaded binaries or .NET assemblies used by execute-assembly and forget about protecting or obfuscating them manually before each usage. The added benefit of an automated approach to transform executables is the ability to have the same executable protected each time it's used, resulting in unique samples launched on target machines. That should nicely deceive EDR/AV enterprise-wide IOC sweeps while looking for the same artefact on different machines.

Additionally, the protected-execute-assembly command has the ability to look for assemblies of which only name were given in a preconfigured assemblies directory (set in dotnet_assemblies_directory setting).

To use it:

Load CobaltStrike/ProtectMyTooling.cna in your Cobalt Strike.
Go to the menu and setup all the options

Then in your Beacon's console you'll have following commands available:

protected-execute-assembly - Executes a local, previously protected and compressed .NET program in-memory on target.
protected-upload - Takes an input file, protects it if its PE executable and then uploads that file to specified remote location.
bofnet_load_protected - Takes input .NET assembly file, passes it through configured .NET packers chain, loads generated output with bofnet_load. BOFNET needs to be loaded separetely for this to work.

Basically these commands will open input files, pass the firstly to the CobaltStrike/cobaltProtectMyTooling.py script, which in turn calls out to ProtectMyTooling.py. As soon as the binary gets obfuscated, it will be passed to your beacon for execution/uploading.

Cobalt Strike related Options

Here's a list of options required by the Cobalt Strike integrator:

python3_interpreter_path - Specify a path to Python3 interpreter executable
protect_my_tooling_dir - Specify a path to ProtectMyTooling main directory
protect_my_tooling_config - Specify a path to ProtectMyTooling configuration file with various packers options
dotnet_assemblies_directory - Specify local path .NET assemblies should be looked for if not found by execute-assembly
cache_protected_executables - Enable to cache already protected executables and reuse them when needed
protected_executables_cache_dir - Specify a path to a directory that should store cached protected executables
default_exe_x86_packers_chain - Native x86 EXE executables protectors/packers chain
default_exe_x64_packers_chain - Native x64 EXE executables protectors/packers chain
default_dll_x86_packers_chain - Native x86 DLL executables protectors/packers chain
default_dll_x64_packers_chain - Native x64 DLL executables protectors/packers chain
default_dotnet_packers_chain - .NET executables protectors/packers chain

Known Issues

ScareCrow is very tricky to run from Windows. What worked for me is following:
1. Run on Windows 10 and have WSL installed (bash.exe command available in Windows)
2. Have golang installed in WSL at version 1.16+ (tested on 1.18)
3. Make sure to have PackerScareCrow.Run_ScareCrow_On_Windows_As_WSL = True set

Credits due & used technology

All packer, obfuscator, converter, loader credits goes to their authors. This tool is merely a wrapper around their technology!
- Hopefully none of them mind me adding such wrappers. Should there be concerns - please reach out to me.
ProtectMyTooling also uses denim.exe by moloch-- by some Nim-based packers.

TODO

Write custom PE injector and offer it as a "protector"
Add watermarking to other file formats such as Office documents, WSH scripts (VBS, JS, HTA) and containers
Add support for a few other Packers/Loaders/Generators in upcoming future:
- GadgetToJScript
- Limelighter
- PEZor
- msfevenom - two variants, one for input shellcode, the other for executable
