The problem of modeling and detecting polymorphic engines shellcode is adressed in this book. By polymorphic engines, we mean programs having the ability to transform any piece of malware into many instances consisting of different code but having the same functionality as the original malware. Typically, polymorphic engines work by encrypting the target malware using various encryption techniques and providing a decryption module in order to execute the newly encrypted instance. Moreover, those engines have the ability to mutate their decryption routine making them unique from one instance to another and hard to detect. We propose a new concept of signatures, shape signatures, which cope with the highly mutated nature of those engines. The shape signatures try to identify the constant part as well as the mutated part of the deciphering routines. This combination is able to cope with the highly mutated nature of those engines in a much more efficient way compared to traditional signatures used in most intrusion detection systems. We also aim at modeling those polymorphic engines by showing that they exhibit a specific byte composition.

This freeware tool enables developers, testers, and enthusiasts to inspect traffic, set breakpoints, and "fiddle" with incoming or outgoing data. Fiddler includes powerful event-based scripting, and can be extended using any .NET language. FiddlerCore, the core proxy engine underlying Fiddler, is available to integrate into any .NET application.
This book provides an easy insight into the essentials of cybersecurity, even if you have a non-technical background. You may be a business person keen to understand this important subject area or an information security specialist looking to update your knowledge. 'The world has changed more in the past 10 years than in any 10 year period in human history. . . Technology is no longer a peripheral servant, it shapes our daily lives. Companies that can use technology wisely and well are booming, companies that make bad or no technology choices collapse and disappear. The cloud, smart devices and the ability to connect almost any object to the internet are an essential landscape to use but are also fraught with new risks and dangers of a magnitude never seen before.' Also featuring an alphabetical section at the back of the book to help you translate many of the main cybersecurity technical terms into plain, non-technical English.
