PaiMei is a reverse engineering framework consisting of multiple extensible components. The goal of the framework is to reduce the time from "idea" to prototype to a matter of minutes, instead of days. PaiMei is written entirely in Python and exposes at the highest level a debugger, a graph based binary abstraction and a set of utilities for accomplishing various repetitive tasks. The framework can essentially be thought of as a reverse engineers swiss army knife and has already been proven effective for a wide range of both static and dynamic tasks such as: fuzzer assistance, code coverage tracking, data flow tracking and more.
