Is anyone can tell me why does the exploit string (of the payload) have to be unique ?
I really don’t understand why ??

shellcode += “\x89\xca”
shellcode += “\xcd\x80”

Why it does not work when I use simple string such like : AAA ?

There’s a lot of context missing here. What works and doesn’t work depends completely on where you are using it.

The strings in the code you pasted aren’t just some random unique values, they are x86 instructions. If you change those, yes, I’m sure it will not work…
