I came across Robert Jones' "Internet Forensics" published by O'Reilly. Despite its low page count (~200 pages), this book is a masterpiece, which provides plenty of very valuable and pragmatic information about computer security and how one can protect herself against scams and contribute to make the Internet cleaner.

My 9-horseshoes review follows (also available at Javaranch.com):

Over the past ten years, the Internet has become an increasingly vital part of our socio-economic ecosystem. As a result, it would not be conceivable to live without it anymore or to switch it off altogether. On the dark side, it is undeniable that the massive use of the Internet also brings its load of troubles that too often rotten the lives of many online users and businesses.

Committed to supporting the fight against the countless illnesses that plague the modern Internet, Robert Jones has contributed a great book called "Internet Forensics". As its title implies, this book delves into the most intimate details of the Internet and aims at raising the readers awareness regarding the many dangers of the Internet and to provide them with the necessary tools to prevent and fight against those dangers. Jones first introduces the design of DNS and IP addresses in order to explain how to dissect a spam network. He goes on analyzing the anatomy of emails and the SMTP protocol. He also describes the countless techniques used by spammers and phishers and how one can protect herself against them. The book also enumerates many techniques for analyzing web sites, web servers and log files and flushing out their malevolent authors. The book finishes by providing some patterns of activity and two real-world case studies that show in a very comprehensive way how to proceed for dismantling spam networks.

I would advise this book to any person who carries out activities on the Internet and for whom privacy and personal integrity is of paramount importance. Of course, the techniques explained in this book require the reader to show some interest in computer security and to have a working knowledge of UNIX or Linux and programming.
