About

Stated simply, This course is about how computers work. In the first part of the course, we will explore computer behavior by means of writing computer programs. Unlike most programmers, we will be writing programs for computers at their most basic level. We will be commanding them directly in assembly code and machine language with the aim of seeing what is going on "under the hood." This type of programming used to be very common anywhere performace was an issue, but in this modern era of plentiful CPU cycles and inexpensive vast memory devices, few people write assembly code these days. Even though the art of writing these kind of programs is becoming rarer, learning assembly language is still a worthy pursuit as it reveals what is going on inside the machine and teaches programmers to "think like a computer." The exploration of assembly will begin with writing programs for the x86 family of processors. In later chapters we will be looking at other architectures and instruction sets. Ideas will be presented in the most general way possible throughout the assembly language chapters so that the reader will have no trouble transitioning to any computing platform / operating system environment. In the second part of the course, we will explore digital electronics with an aim to designing a CPU. In this section, we will be using a logic circuit simulator to put the computer together. You will be able to execute software on this fictional computer, and if you really wanted to you could implement it in physical hardware. After completing this part of the course you will have intiment knowledge of the theory behind computer operation. In the last chapter of the second part, we will explore various sample programs and present some ideas for how the computer we design could be expanded.

CEMU

Writing assembly is fun. Assembly is the lowest language (humanly understandable) available to communicate with computers, and is crucial to understand the internal mechanisms of any machine. Unfortunately, setting up an environment to write, compile and run assembly for various architectures (x86, ARM, MIPS, SPARC) has always been painful. CEmu is an attempt to fix this by providing a bundled GUI application that empowers users to write assembly and test it by compiling it to bytecode and executing it in an QEMU-based emulator. CEmu combines all the advantages of a basic assembly IDE, compilation and execution environment, by relying on the great libraries GUI. It allows to test binary samples, check your shellcodes or even simply learn how to write assembly code, all of this for the following architectures: CEmu was tested and works on Linux, Windows and MacOSX.

About

Kam1n0 v2.x is a scalable assembly management and analysis platform. It allows a user to first index a (large) collection of binaries into different repositories and provide different analytic services such as clone search. It supports multi-tenancy access and management of assembly repositories by using the concept of Application. An application instance contains its own exclusive repository and provides a specialized analytic service. Considering the versatility of reverse engineering tasks, Kam1n0 v2.x server currently provides three different types of clone-search applications: Asm-Clone, Sym1n0, and Asm2Vec. New application type can be further added to the platform.

A user can create multiple application instances. An application instance can be shared among a specific group of users. The application repository read-write access and on-off status can be controlled by the application owner. Kam1n0 v2.x server can serve the applications concurrently using several shared resource pools. Kam1n0 was developed by Steven H. H. Ding and Miles Q. Li under the supervision of Benjamin C. M. Fung of the Data Mining and Security Lab at McGill University in Canada. It won the second prize at the Hex-Rays Plug-In Contest 2015. If you find Kam1n0 useful, please cite our paper:

  Asm-Clone

  Asm-Clone applications try to solve the efficient subgraph search problem (i.e. graph isomorphism problem) for assembly functions (
