Endorsements and Reviews of the Book
»This is one of the most interesting infosec books to come out in the last several years.«
»While no book will turn you into an expert bug hunter overnight, the dozens of insightful tricks and tips in "A Bug Hunter's Diary" will certainly put you on the right track. Tobias demonstrates his technical expertise as he adeptly covers a wide range of platforms and techniques in a journey that's packed with both useful information and fun. This book is a great read for newcomers and experts alike, and is sure to inspire readers to pick new targets and start finding bugs of their own.«
»Really enjoyed A Bug Hunter's Diary. Short and to the point. Excellent for people wanting to get into vulnerability hunting.«
»I definitely recommend this book for anyone who is just starting out in this field and is interested to know exactly what the process of finding software vulnerabilities is like.«
»What [Tobias Klein] does do, and does very well, is draw a straight line from source or assembly to the beginning stages of a viable exploit. It is a very satisfying book to read and there are great bits of knowledge to be had.«
»Tobias Klein is an excellent security researcher with experience in both closed and open source bug hunting as well as exploit development in many different architectures. I would definately suggest this book to anyone interested in real world bug hunting and exploitation and not just vuln.c programs.«
»As a diary, I believe it is one of the best books I have read so far. Easy writing style, interesting bugs and illustrative pictures and code listings are the key points making it so successful. [..] That said, I would especially recommend A Bug Hunter's Diary as an excellent supplement of a security textbook to everyone making his first steps in the software security field.«
