This book is not a how to on hacking. At best it is an overview of hacking and malware, or malwares, as the author refers to them. The book adequately describes the different types of hackers, attacks and hacking tools, however, all this information is easily and freely available on the web. With the exception of a single batch file, there are no code examples. The book is rife with awkward and incorrect grammar. It is evident that English is not the author's first language, nor was it edited by a native English speaker.
