UEFI Firmware Fuzzing with Simics Virtual Platform
UEFI Firmware Fuzzing with Simics Virtual Platform Zhenkun Yang, Yuriy Viktorov, Jin Yang, Jiewen Yao and Vincent Zimmer Intel Corporation fzhenkun.yang, yuriy.viktorov, jin.yang, jiewen.yao, [email protected] Abstract—This paper presents a fuzzing framework for Unified write everything on the platform, while being invisible to OS Extensible Firmware Interface (UEFI) BIOS with the Simics vir- and anti-virus software. tual platform. Firmware has increasingly become an attack target Software community has common practices and great tools as operating systems are getting more and more secure.

Fortunately, advanced techniques such as fuzzing, symbolic execution virtual platforms are widely used to enable early software and and static analysis are becoming popular. However, firmware firmware development by modeling the target hardware platform development and validation community faces numerous chal- in its virtual environment before silicon arrives. Virtual platforms play a critical role in left shifting UEFI firmware validation lenges applying those tools due to the special execution to pre-silicon phase. We integrated the fuzzing capability into environments firmware is running on. The execution regime of Simics virtual platform to allow users to fuzz UEFI firmware boot firmware does not resemble any known operating system code with high-fidelity hardware models provided by Simics. runtime, such as Linux or Windows, thus requiring custom, We demonstrated the ability to automatically detect previously bespoke solutions. -

Bootstrapping a Compiler for Fun and Profit
Starting From Scratch Bootstrapping a Compiler for Fun and Profit Disclaimer: Profit not guaranteed Neither is fun. A background in compilers is neither assumed, implied, nor expected. Questions are welcome; and will be answered, possibly correctly. What’s a Compiler? A program that translates from one programming language into another programming language. To create a compiler, we need at least three things: A source language(e.g. C, Java, LLVM byte code) A target language (e.g. C, Java ByteCode, LLVM byte code, or the machine code for a specific CPU) to translate it to Rules to explain how to do the translation. How do we make a great compiler? There are two approaches to this problem. A) Write the perfect compiler on your very first try. (Good luck!) B) Start out with a not-so-great compiler. Use it to write a better one. Repeat. That’s great, but… What if I don’t have a not-so-great compiler to start out with? What if I don’t have a compiler at all? The Modern Answer: Just Google it. Someone will have written one for you by now. If they haven’t, you can start with an existing compiler for an existing source language (such as C), and change the target language that it generates. Starting from Scratch… What did we do before we had the Internet? What would we do if we didn’t have a compiler to start from? We’d make one! There are many possible ways to go about doing this. Here’s my approach… What are we trying to Do? We want to write a program that can translate from the language we HAVE to the language we WANT. -

Bringing the Openbmc for Platform Manage- Ment System in Telco Cloud
Rongqiang Zhang Bringing the OpenBMC for Platform Manage- ment System in Telco Cloud Helsinki Metropolia University of Applied Sciences Master of Engineering Information Technology Master’s Thesis 30 Apr 2019 Abstract Rongqiang Zhang Author(s) Bringing the OpenBMC for Platform Man-agement System in Title Telco Cloud Number of Pages 88 pages + 0 appendices Date 30 Apr 2019 Degree Master of Engineering Degree Programme Information Technology Specialisation option Networking and Services Ville Jääskeläinen, Head of Degree Program Instructor(s) Zinaida Grabovskaia, PhL, Senior Lecturer Antti Koivumäki, Senior Lecturer Ari Helminen, Business Manager The current platform management system in Telco cloud infrastructure is based on closed firmware stack. With the upcoming 5G, this closed firmware stack has created several tech- nology and business problems. The major problems are hardware-software vendor lock-in, long lead time for feature development and bug fixing, and security risks. The objective of this study is to evaluate the possibility to bring an Open Source software stack for platform management system and baseboard management controller in Telco cloud. The study was divided into 3 parts. First part is to analyse the current state and project specification. Second part is to introduce and evaluate the OpenBMC, an open source soft- ware stack for the objective of this study. Third part is Proof of Concept to run OpenBMC on Telco.

Trapper: an Operating System Bootstrapping Package for IBM PC Compatible Computer Systems
Программные продукты и системы /Software&Systems 2 (33) 2020 Software &Systems Received 26.09.19 DOI: 10.15827/0236-235X.130.210-217 2020, vol. 33, no. 2, pp. 210–217 Trapper: an operating system bootstrapping package for IBM PC compatible computer systems Y.I. Klimiankou 1, Postgraduate Student, [email protected] 1 Belarusian State University of Informatics and Radioelectronics, Minsk, 220013, Belarus The paper presents an overview of the bootstrapping process on the IBM PC-compatible computer systems and proposes an architecture of the operating system bootstrapping package. The proposed package implements a framework for constructing boot images targeted at non-traditional operating systems like microkernel, an exokernel, unikernel, and multikernel. The bootstrapping package consists of three sets of independent boot modules and a Boot Image Builder application, which creates OS boot images. This application integrates and chains boot modules with one another to organize a complete bootloader chain. They are necessary to bring the operating system to a working state. The bootstrapping package architecture reflects the principal stages of the computer system boot process. Each set of boot modules is connected to the particular boot stage and forms a layer that is responsible for performing its own clearly defined set of functions and relies on clearly defined inter-layer interfaces to strictly isolate dependencies on the boot device, firmware and the specifics of the boot- loaded operating system. The paper presents the implementation of the described architecture for boot image generation designed and implemented for a research multikernel operating system and explains how it boots up. Additionally, the paper proposes the full separation idea of initialization code out of the operating system kernel and its movement into the independent OS loader module. -
3 Compiler Construction and Bootstrapping
Compilers and Compiler Generators © P.D. Terry, 2000 3 COMPILER CONSTRUCTION AND BOOTSTRAPPING By now the reader may have realized that developing translators is a decidedly non-trivial exercise. If one is faced with the task of writing a full-blown translator for a fairly complex source language, or an emulator for a new virtual machine, or an interpreter for a low-level intermediate language, one would probably prefer not to implement it all in machine code. Fortunately one rarely has to contemplate such a radical step. Translator systems are now widely available and well understood. A fairly obvious strategy when a translator is required for an old language on a new machine, or a new language on an old machine (or even a new language on a new machine), is to make use of existing compilers on either machine, and to do the development in a high level language. This chapter provides a few examples that should make this clearer. 3.1 Using a high-level host language If, as is increasingly common, one’s dream machine M is supplied with the machine coded version of a compiler for a well-established language like C, then the production of a compiler for one’s dream language X is achievable by writing the new compiler, say XtoM, in C and compiling the source (XtoM.C) with the C compiler (CtoM.M) running directly on M (see Figure 3.1). This produces the object version (XtoM.M) which can then be executed on M. Even though development in C is much easier than development in machine code, the process is still complex. -
