b2exe

A cross compatible ba(tch|sh) compiler. (WORK IN PROGRESS)
It should be noted i designed this with the primary purpose of generating exes out of batch code on windows, however, the generated code will also compile and work* on unix based systems.
*this does not mean bash code will run on windows, same should be said for batch and linux
The release has compiled binaries for each platform as well as source code
All binaries were made using pkg from npm i -g pkg and built with pkg .
Latest release can be found here.

Features

• 0/70 detection
• encryption (stub and payload)
• compression (stub and payload)
• bind files
• and so much more!

Installation

There are a few ways to install, although no matter what you need to install the dependencies
I would recommend just installing through npm as it is the easiest way to install and update.

npm (2 different ways)

install:

npm i -g b2exe

this stays on your system until npm remove -g b2exe is ran
temporary:

npx b2exe

only good for running once, as its deleted after execution

git

git clone https://github.com/aydynx/b2exe.git
cd b2exe
npm i
node .

Dependencies

all of these must be installed and added to your path

• Node.js
• gcc & g++

Usage

first run

npm run test
this checks if g++ and gcc are installed, then runs b2exe and compiles a test file
you can run run the executable by typing test.exe or opening it

usage: b2exe <input file> [options]

Options:
  -i, --input     path or name to a batch file                          [string]
  -o, --output    path or name of the output                            [string]
  -x, --xor       encrypt the source code using xor
  -b, --base64    encrypt the batch code using base64 <iterations>      [number]
  -s, --stub      extract batch stub then run it <extract path>         [string]
  -z, --compress  compress batch code <iterations>                      [number]
  -n, --hidden    no console window
  -c, --code      get c++ source instead of exe
  -a, --admin     run as admin
  -t, --sign      sign the exe (path to signed exe)                     [string]
  -m, --mask      resource file to be used
  -u, --upx       use upx to compress the exe
  -p, --icon      icon for the exe                                      [string]
  -d, --debug     debug mode
  -v, --version   show version number
  -h, --help      run --help <command> to see more info on an option

compiling a batch file

b2exe <batch file> [options]
generates an executable in the path of the batch file called hello.exe

getting cpp code

b2exe <batch file> -c
only the source to the exe that would have been generated is output

protecting a batch file

b2exe <batch file> -b 1 -z 1
encrypts the batch code in base64*, then compresses it which also further obfuscates your script
*every pass of base64, your command will 2.5x

embedding batch as a stub

b2exe <batch file> -s <file path>
this is useful for large batch file that would otherwise go over the windows max command length limit
using this will add ~1.1mb onto your script. large scripts can add more, but the size can be reduced by using the --compress flag

debug

b2exe <batch file> [options] -d
shows args, prints more info to console, see how code is processed

important stuff

/dependencies/bin/

These files are needed for some of the functions to work, but not needed to just compile a batch file.
mage.exe:
used to generate the manifest file for the exe, from the windows 11 sdk

upx.exe:
used to compress the exe and resources, from the upx repo

used to append signature to file, from the sigthief repo

stub detection

It should be noted that while i will try to maintain source code and issues, i will not make an update just because it gets detected on virustotal or other similar file scanning sites.
if you want this to stay 0/70 detections, dont submit this to sites that share samples please. I have included a virustotal submission so you dont have to. do not rescan.
