Possibility of arbitrary code execution by Step-Oriented Programming
Possibility of arbitrary code execution by Step-Oriented Programmingkozossakai Step-Oriented Programming (SOP) allows executing arbitrary code on embedded systems by repeating step execution and changing the program counter value. A debugger communicates with a target system's stub using the Remote Serial Protocol to read/write memory and registers, enabling full control via simple commands if the connection is compromised. SOP constructs code by combining pieces of existing machine code and executes it without needing to directly inject new code. Therefore attacks are possible even if execution from data areas is prevented. The presentation will demonstrate this attack principle and results from actual experimentation.
Possibility of arbitrary code execution by Step-Oriented Programming by Hiroa...
Possibility of arbitrary code execution by Step-Oriented Programming by Hiroa...CODE BLUE An embedded system has a stub to connect with a host PC and debug a program on the system remotely. A stub is an independent control program that controls a main program to enable debugging by a debugger. A stub is simplified by only processing the simple controls such as reading or writing of the register or of a memory, and a debugger processes a complicated analysis on the host PC.
Communication with a debugger on the host PC and a stub on the embedded system is performed by a protocol called Remote Serial Protocol (RSP) over a serial communication or TCP/IP communication. If this communication is taken away, it becomes possible to operate a stub arbitrarily. We considered what kind of attack possibility there was in that case, and identified that execution of arbitrary code constructed from pieces of machine code, combined with (SOP: Step-Oriented Programming) is possible by repeating step execution while changing the value of the program counter. Therefore it is possible to construct an arbitrary code and execute it from existing machine code, even if execution of the injected machine code is impossible because execution on data area is prevented by DEP or only machine code on the flash ROM are allowed execution.
I will explain about an attack principle by SOP and the results from constructed attack code and actual inspection.

It discusses different types of bugs, the benefits of writing unit tests, test types like unit tests and integration tests, testability factors, isolation techniques using test doubles, common mistakes to avoid, and Microsoft Fakes for improving testability. The key points covered are:
- The importance of writing tests to prevent bugs and allow safe refactoring.
- Techniques like dependency injection, interfaces, and seams to make code more testable and allow isolation using stubs, fakes, mocks, and shims.
- Common mistakes for test code like testing multiple features in one test, long test runs without maintenance, lack of negative testing, and unclear
Beyond Breakpoints: A Tour of Dynamic Analysis
Beyond Breakpoints: A Tour of Dynamic AnalysisFastly Despite advances in software design and static analysis techniques, software remains incredibly complicated and difficult to reason about. Understanding highly-concurrent, kernel-level, and intentionally-obfuscated programs are among the problem domains that spawned the field of dynamic program analysis. More than mere debuggers, the challenge of dynamic analysis tools is to be able record, analyze, and replay execution without sacrificing performance. This talk will provide an introduction to the dynamic analysis research space and hopefully inspire you to consider integrating these techniques into your own internal tools.
Exploiting Multicore CPUs Now: Scalability and Reliability for Off-the-shelf ...
Exploiting Multicore CPUs Now: Scalability and Reliability for Off-the-shelf ...Emery Berger Multiple core CPUs are here. Conventional wisdom holds that, to take best advantage of these processors, we now need to rewrite sequential applications to make them multithreaded. Because of the difficulty of programming correct and efficient multithreaded applications (e.g., race conditions, deadlocks, and scalability bottlenecks), this is a major challenge.
This talk presents two alternative approaches that bring the power of multiple cores to today's software. The first approach focuses on building highly-concurrent client-server applications from legacy code. I present a system called Flux that allows users to take unmodified off-the-shelf *sequential* C and C++ code and build concurrent applications. The Flux compiler combines the Flux program and the sequential code to generate a deadlock-free, high-concurrency server. Flux also generates discrete event simulators that accurately predict actual server performance under load. While the Flux language was initially targeted at servers, we have found it to be a useful abstraction for sensor networks, and I will briefly talk about our use of an energy-aware variant of Flux in a deployment on the backs of endangered turtles. The second approach uses the extra processing power of multicore CPUs to make legacy C/C++ applications more reliable. I present a system called DieHard that uses randomization and replication to transparently harden programs against a wide range of errors, including buffer overflows and dangling pointers. Instead of crashing or running amok, DieHard lets programs continue to run correctly in the face of memory errors with high probability. This is joint work with Brendan Burns, Kevin Grimaldi, Alex Kostadinov, Jacob Sorber, and Mark Corner (University of Massachusetts Amherst), and Ben Zorn (Microsoft Research).

MongoDB 2.8 Replication Internals: Fitting it all together
MongoDB 2.8 Replication Internals: Fitting it all togetherScott Hernandez MongoDB replication internal architecture for 2.8
Abstract:
Replication in MongoDB requires deep integration with almost every part of the codebase, and has important hooks in various systems like storage, indexing, command processing and querying. Most of the replication components have seen a major overhaul recently in order to make further improvements. In this talk we will address what those pieces are, how they interact, and interesting choices made during their design. In this talk we get into the interaction of the replication protocols, commands really, writes and write concern enforcement, consensus (elections/ leader/follower/ majority) behaviors, and down into the depths of oplog generation and application on replicas. While a large part of the talk will be a technical overview of the big pieces we will dive into many important areas in order to ensure better understanding. The audience will be able to greatly affect which areas we focus on during the session, so come with ideas and a focus.

Is AI just another technology, or does it fundamentally change the way we live and think?
Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater.
At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts.
At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.
