Stop manually analyzing binary! Practical Binary Analysis is the first book of its kind to present advanced binary analysis topics, such as binary instrumentation, dynamic taint analysis, and symbolic execution, in an accessible way. As malware increasingly obfuscates itself and applies anti-analysis techniques to thwart our analysis, we need more sophisticated methods that allow us to raise that dark curtain designed to keep us out--binary analysis can help. The goal of all binary analysis is to determine (and possibly modify) the true properties of binary programs to understand what they really do, rather than what we think they should do. While reverse engineering and disassembly are critical first steps in many forms of binary analysis, there is much more to be learned. This hands-on guide teaches you how to tackle the fascinating but challenging topics of binary analysis and instrumentation and helps you become proficient in an area typically only mastered by a small group of expert hackers. It will take you from basic concepts to state-of-the-art methods as you dig into topics like code injection, disassembly, dynamic taint analysis, and binary instrumentation. Written for security engineers, hackers, and those with a basic working knowledge of C/C++ and x86-64, Practical Binary Analysis will teach you in-depth how binary programs work and help you acquire the tools and techniques needed to gain more control and insight into binary programs. Once you´ve completed an introduction to basic binary formats, you´ll learn how to analyze binaries using techniques like the GNU/Linux binary analysis toolchain, disassembly, and code injection. You´ll then go on to implement profiling tools with Pin and learn how to build your own dynamic taint analysis tools with libdft and symbolic execution tools using Triton. You´ll learn how to: - Parse ELF and PE binaries and build a binary loader with libbfd - Use data-flow analysis techniques like program tracing, slicing, and reaching definitions analysis to reason about runtime flow of your programs - Modify ELF binaries with techniques like parasitic code injection and hex editing - Build custom disassembly tools with Capstone - Use binary instrumentation to circumvent anti-analysis tricks commonly used by malware - Apply taint analysis to detect control hijacking and data leak attacks - Use symbolic execution to build automatic exploitation tools With exercises at the end of each chapter to help solidify your skills, you´ll go from understanding basic assembly to performing some of the most sophisticated binary analysis and instrumentation. Practical Binary Analysis gives you what you need to work effectively with binary programs and transform your knowledge from basic understanding to expert-level proficiency.

This is a stunning visual guide to the life and works of entrepreneur Steve Jobs. Easily one of the most influential innovators of the twenty-first century, Steve Jobs has fundamentally shaped the way in which we communicate and, even more broadly, live our lives. In this information-packed graphic biography, Steve Jobs´ remarkable talent and genius are explored through bold design and original graphics. Kevin Lynch explores Jobs´ journey from savvy salesman, to his rivalry and market competition with Bill Gates, and his shift towards radical innovations in later life. This technological innovator led a fascinating, astounding and ultimately too short life, that irreversibly impacted how we communicate. Steve Jobs is a visual celebration and comprehensive study of ´The Maverick´ and his work; and a must-have for any fan of Apple products.

Ein Ratgeber, der Mut macht. Für Einzelunternehmer und Freiberufler. Wer überlegt, sich selbstständig zu machen, der fragt sich beim letzten Schritt heraus aus der Komfortzone: ´´Kann ich das? Bin ich gut genug?´´, ´´Was ist, wenn es schiefgeht? Reicht das Geld zum Leben?´´ Hinzu kommt ein warnendes Umfeld, das nicht die Unterstützung leistet, die ein Gründer benötigt. Daniel Held hat diese mentalen Hürden genommen und als freier Online-Redakteur schnell Fuß gefasst. In seinem Buch zeichnet er die ersten drei Jahre seiner Selbstständigkeit nach und beleuchtet psychologische und emotionale Faktoren sowie gesellschaftliche Glaubenssätze. Er erklärt, wie man sich mit gelungener Akquise, Honorarkalkulation und Vermarktung zielgerichtet einen stabilen Kundenstamm aufbaut. ´´Ohne Zweifel selbstständig´´ ist ein bodenständiger Begleiter mit wertvollen Tipps auch für erfahrene Freiberufler, um motiviert nach eigenen Werten zu leben und schrittweise erfolgreich(er) zu werden. Dabei greift Daniel Held auch auf Tricks aus dem Mentalsport Tischtennis zurück, wo der Glaube an sich selbst essentiell ist.

Kein Computer ist so oft verkauft worden wie der Commodore C 64. Unvergessen sind auch Sinclairs ZX 81, VC 20, Amiga, Atari ST und Schneiders CPC 464. Die 8-Bit- und 16-Bit-Rechner der 1980er Jahre waren für viele die ersten digitalen Geräte ihres Lebens. Aber nicht nur die Technik im Innern ist mittlerweile Kult, sondern auch ihr äußeres Design. Fotograf Reiner Silberstein hat diese Oldtimer der Computer-Technik in atemberaubender Weise fotografiert: In der Light-Painting-Technik. Dabei bewegt er die Lichtquellen während einer Langzeitbelichtung um die Objekte. Das Resultat sind spektakuläre Bilder, die wirken, als seien sie Teil einer Neonlicht-Installation.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.RAID is an acronym first defined by David A. Patterson, Garth A. Gibson, and Randy Katz at the University of California, Berkeley in 1987 to describe a redundant array of inexpensive disks, a technology that allowed computer users to achieve high levels of storage reliability from low-cost and less reliable PC-class disk-drive components, via the technique of arranging the devices into arrays for redundancy. Marketers representing industry RAID manufacturers later reinvented the term to describe a redundant array of independent disks as a means of dissociating a ´´low cost´´ expectation from RAID technology.
