OWASP ZSC Project

OWASP ZSC is an open source software in python language which lets you generate customized shellcodes and convert scripts to an obfuscated script. This software can be run on Windows/Linux/OSX under python.

Usage of shellcodes

Shellcodes are small codes in assembly which could be use as the payload in software exploiting. Other usages are in malwares, bypassing anti viruses, obfuscated codes and etc.

Usage of Obfuscate Codes

Can be use for bypassing antiviruses , code protections , same stuff etc …

Why use OWASP ZSC ?

According to other shellcode generators such as metasploit tools and etc, OWASP ZSC using new encodes and methods which antiviruses won't detect. OWASP ZSC encoders are able to generate shellcodes with random encodes that lets you to get thousands of new dynamic shellcodes with the same job in just a second, it means you will not get a same code if you use random encodes with same commands, and that makes OWASP ZSC one of the bests! otherwise it's going to generate shellcodes for other operation systems in the next versions. It’s the same story for the code obfuscation.

User Guides

To run OWASP ZSC, You need to install python `2.x|3.x` on your operation system `Windows|Linux|OSX`, Then it could be run directly with executing `zsc.py` or run the software after you installed it! To see the user manuals, Please follow the next steps!

Generating Shellcode

Via `zsc` command , you are able to enter the software [or run python zsc.py if you don’t want install it], Then you can have list of menu with entering `help`. You can have your choices with pressing `tab` key on each step. To generate shellcode , you have to type `shellcode` and then press enter, after that, you can see what’s available in `shellcode` section. There is `generate` , `search` and `download` choices in here which use for `generate shellcodes` , `search` and `download` shellcode from shellstorm. To generate a shellcode, type `generate` and press enter, after that with a `tab` key, you can have list of operation systems available in there. With pressing `tab` key again, functions will be shown for you in this step [ such as `exec` ,`systm`,`write` and `etc`]. choose your function by writing the name `example: exec` and press inter. In the next section you have to fill the argv of function which exec() function have one `example: exec("/bin/bash")`, all you need in this section is pressing a `tab` and then `enter` key, software will automatically ask you for function argv. Fill them and next section software will ask you for shellcode type which can be `none` or choose one of listed encoding types. After entering that, your shellcode is ready! There is one more way to have a shellcode from software, which is using shellstorm API. Following the `shellcode`, and then `search` commands to search for a shellcode. After that shellcodes will be listed for you with title name , ID and etc. you can download them with following `shellcode` and then `download` command to download them with the ID which shown to you in the past section! For canceling each section, you can use `restart` command to restart the software and start new task!

Generating Obfuscate Code

With the following `obfuscate` command, you can begin the step for obfuscating a code. With a `tab` key , you can see the list of languages along with the obfuscating module ready. After choosing the language software will ask you for a filename which is a filename of file you want to obfuscate that! Next step software will ask you for encode type. With a `tab` key list the encode modules and choose your encode name. your file rewrited and converted to a obfuscate with encode type you chosen. And do not worry about your original code, it’s saved in file as a comment!

Installation Go to download page, and download last version in github. Extract and run installer.py, then you are able to run software with OWASP ZSC command or you can directly execute zsc.py without installing it.or you can follow these commands to install the last version:

wget https://github.com/Ali-Razmjoo/OWASP-ZSC/archive/master.zip -O owasp-zsc.zip && unzip owasp-zsc.zip && 
rm -rf owasp-zsc.zip && mv OWASP-ZSC-master owasp-zsc && cd owasp-zsc && python installer.py

Note: Software could be uninstall with executing uninstaller.py

Note: Software installation directory is "/usr/share/owasp-zsc"

Note: OWASP ZSC Tool could be execute on Linux and Python 2.7.x is required.

Roadmap

As of August, 2015, the highest priorities for the next one year are:

Subsequent Releases will add

OWASP ZSC could be improving with handling module features. MVP of this project is build and active the first module which could be usable to generate/encode Shellcode which already some of them [modules] activated.

Highest usage of OWASP ZSC Tool could be when users are able to use all features with best User Interface and API performance.

Be an OWASP ZSC developer

Developers can add new features and if you don’t have an idea but like to develop, you can submit the issue, which software needs to be fix/add/done in HERE.

After fix/add or develop something, please send your pull request and remember that your code must be compatible with python2 and python3. If you have any question you can open an issue or just mail us. do not forget to register on our mailing list.
