Currently reading a book about cybercrime and espionage I found one chapter about state-sponsored intelligence. Now I fear that I was fallen into the trap of an secret enemy: The authors are naming various international intelligence organizations, e.g. GIP (Saudia Arabia) and a North Korean organization. But… both organizations are labeled in this book with the same sign. And the trick? I immediately wrote an email to the authors, praised their really interesting book and pointed to their mistake. What happened? Nothing. They didn´t responded me not because they are arrogant. They just wanted to find out where in the world could be one attentive expert and now they knew… Btw: the book was just too expensive. And I start hating all these books about hacking and cybercrime with pages full of screenshots and nothing else but three words on one page.
