Your first task as an Evil Hacker$$ is to develop your very own shellcode. Shellcode is binary code that, when executed by a CPU, uses a system call to launch an interactive shell, giving an attacker free rein over the system. Thus, the ultimate goal of an attacker is to inject their shellcode into a program and get it to run.

On UNIX systems, like the Linux student servers, the shell program is named $/$bin$/$sh$.$ Therefore, you will develop a piece of code that will execute this program.

Shellcode, when executing, cannot make any assumptions about the environment $($e$.$g$.$ it cannot rely on any data already in memory besides itself$).$ This can make developing shellcode challenging.
