SLAE32

This course focuses on teaching the basics of 32-bit assembly language for the Intel Architecture (IA-32) family of processors on the Linux platform and applying it to Infosec. This course provide the necessary knowledges for writing shellcode, encoders, decoders, crypters and other advanced low level applications (e.g. polymorphism).

Assignment 7 - Crypter

Description of the assignment
  • Create a custom crypter like the one shown in the “crypters” video
  • Free to use any existing encryption schema
  • Can use any programmming language

Description of the assignment
  • Take up at least 3 shellcodes from shell-Storm and create a polymorphic versions to beat the pattern matching
  • The polymorphic version cannot be larger than 150% of the existing shellcode
  • Bonus points for making it shorter in length than the original

As follows the list of shellcodes that we are going to change into polymorphic ones:

  • downloadexec
  • ...

Description of the assignment
  • Take up at least 3 shellcode samples created using Msfpayload for linux/x86
  • Use GDB/NDisasm/Libemu to dissect the functionality of the shellcode
  • Present your analysis

We are going to analyse together the following shellcodes:

  • linux/x86/adduser
  • ...
