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

END USER IS LIABLE FOR THEIR OWN ACTIONS

In order to run these shellcodes, the following dependencies are required:

Linux
GCC
Generators require Python 2.7
Automake

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 If you think you may have an out of date version, or that the official version is out-of-sync with the site, the latest sources will be available 100% of the time in the shellcode appendix.

Nicely assemble and output shellcode in a variety of formats (raw, hex, and as a C variable) (shellcode-generator.py)
Hash-generator for self-linking shellcode 81 bytes (hash-generator.s)
Socket-reuse shellcode generator (socket-reuse-generator.py)
Polymorphic socket reuse generator (poly-socket-reuse-generator.py)
Sends socket reuse shellcode (socket-reuse.c)
32-bit shellcode packer 37 bytes (packer-32.s) (Shellcode/Self-modifying#32_bit)
64-bit shellcode packer 55 bytes (packer-64.s) (Shellcode/Self-modifying#64_bit)

Payloads

Short unlinked 64-bit null-free setuid(0); execve('/bin/sh',0,0); 32 bytes (setuid_binsh.s) (Docs)
Small unlinked 32-bit null-free write-to-file payload 90 bytes (write-file-32.s) (Docs)
Null-free unlinked same-socket-shell payload 115 bytes (socket-reuse.s) (Docs)
Alphanumeric amd64 execve('/bin/sh',0,0) 104 bytes (ascii_binsh.s) (Docs)
Null-free dynamic ELF64 exit code 135 bytes (linked-exit.s) (Docs)
Null-free dynamic ELF64 socket reuse shellcode 268 bytes (linker-fd-reuse.s) (Docs)
Null-free polymorphic dynamic ELF64 socket reuse shellcode 268 bytes (poly-linker-fd-reuse.s)

Stubs

A 32-bit getpc (%eax) example 11 bytes (getpc-32.s) (Docs)
A 64-bit getpc (%rax) example 12 bytes (getpc-64.s) (Docs)
Alternative 64-bit getpc 10 bytes (getpc-64-alt.s) (Docs)
Int3 detection code 24 bytes (int3-detect-64.s) (Docs)
32-bit lastcall example code 4 bytes (lastcall-32.s) (Docs)
64-bit lastcall example code 5 bytes (lastcall-64.s) (Docs)
64-bit alphanumeric lastcall example code 13 bytes (lastcall-alphanum.s) (Docs)
Alphanumeric x86* compatible getCPU 15 bytes (architecture_detection) (Docs)
32-bit shellcode unpacker 89 bytes (decoder-32.s) (Docs)
64-bit shellcode unpacker (mmap) 102 bytes (decoder-64.s) (Docs)
64-bit shellcode unpacker 69 bytes (decoder-64.s) (Docs)

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.

Using the tools

   [loaders]
   [generators]

          Reminder: Docs are available at 
      http://www.blackhatlibrary.net/shellcode 
  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.
