Genetic programming platform for evolving ROP-chain payloads,
implemented in Rust. Under construction.

                          BRIEF EXPLANATION

ROPER is a genetic ROP-chain compiler that I have designed and developed. It
compiles ROP-chains, by creating a miniature ecosystem in which ROP-chains
evolve.  ROPER can be used to develop payloads -- including payloads that
exhibit learned or evolved behaviour -- unlikely to be developed by humans.

Definitions:

1. Return-Oriented Programming is an exploit technique that, instead of writing
malicious code ("shellcode") into a process' executable memory, collages
together a series of "gadgets" that already subside in executable memory. This
is useful when the process has no memory segments that are flagged as both
executable and writeable (W^X/DEP). 

2. Genetic programming is the implementation of natural selection in code.  A
population of random programmes (in this case, ROP-chains) is generated. A
fitness function is then defined, and used to rank the results of their
execution. Fitter programmes are made more likely to breed. Mutation operators
are applied to the offspring, and the next generation of the process begins.
This carries on until the desired outcome is obtained.
