In this section we will learn how to encode and decode our shellcodes in memory using assembly programming. This will help you to understand the concept of encoding and decoding of shellcodes.

In this lecture you will learn a very good concept of decoding the shellcodes in memory at runtime using assembly instructions.

In this lecture we will encode our hello world shellcode and then we use the assembly program shellcode to decode the encoded shellcode in memory at runtime. You will learn a very good concept of decoding the shellcodes in memory at runtime using assembly instructions.

In this video lecture we are going to make some good memory analysis using GDB debugger in which we will see how encoded shellcode is decoded in memory using our assembly program which decodes the encoded shellcode in memory using a decoding procedure in assembly.

In this lecture first we will encode our /bin/sh shellcode then we will create an assembly program which decodes it at runtime. We use this decoder assembly instructions as a shellcode to decode all the /bin/sh encoded shellcode in memory to successfully execute it in memory.

We will use gdb debugger to see the decoding process of our decoder shellcode which decodes our /bin/sh shellcode in running memory.
