Shellcodecs is a collection of shellcodes, loaders, sources, and generators designed to ease the exploitation and shellcode programming process.
These shellcodes are provided with documentation located at Shellcode

In order to run these shellcodes, the following dependencies are required:
Shellcodecs is a collection of shellcodes, loaders, sources, and generators designed to ease the exploitation and shellcode programming process.
Unless otherwise noted, code is amd64. There are various intel32 etc examples as well. If you're unaware, amd64 is the main linux tree for 64-bit, so if you have an intel, you should still be ok. If you think you may have an out of date version, or that the official version is out-of-sync with the site, the latest sources will be available 100% of the time in the shellcode appendix.

Building the code
* tar xzvf shellcode.tgz * cd shellcode * make It is also possible to make exclusively x86 or x64 binaries using make x86 or make x64. Please keep in mind, there is more support for 64-bit in this package than 32-bit.

Reminder: Docs are available at

If you're using the tools and there's a problem, try
re-reading the documentation before asking a question. If you're absolutely sure it is programmatical error and not user error preventing the code from working properly, you can let us know by joining our IRC or talking on the shellcode talk page.
