Greets.

The ability to design good, reliable (and generally small) bytecode is an important skill for a hacker. Bytecode is used in a lot of exploit code: Exploiting a buffer overflow is generally done by injecting shellcode (Which is just byte code that executes a shell) and having the operating system execute it. Usually, if you want your code to execute, you use shellcode (barring techniques such as ret2libc)

For those who've never heard of byte/shellcode before: http://en.wikipedia.org/wiki/Shellcode

I suggest a series of challenges that require the user to create bytecode to preform a specific task: Perhaps print some text to the screen, or execute a shell, or execute a shell and bind it to a listening socket.

Points would be awarded for things such as the size, reliability, originality, etc.

Due to the nature of bytecode, submissions would have to be reviewed by administrators with a lot of experience with bytecode.

A series of challenges such as this would encourage people to learn more about assembler, an important language to know as you deleve deeper into computers.
