A Bug Hunter's Diary vs Hacking: The Art of Exploitation: Which Should You Read?
Two cybersecurity books on Offensive, compared honestly: who each is for, what each does best, and which to read first.
A Guided Tour Through the Wilds of Software Security
Tobias Klein
Tobias Klein walks through seven real vulnerabilities he found and exploited, in the form of personal lab notes, what he tried, what failed, and what eventually shipped to vendors.
A from-first-principles tour of low-level exploitation that still teaches the mindset two decades later.

Key takeaways
- Real vulnerability research is mostly hypothesis-and-failure; Klein's diary format teaches the resilience the field demands.
- Sample selection (which target, which feature, which bug class) is the highest-leverage choice; the book makes this explicit in a way most write-ups skip.
- Disclosure tradecraft (vendor coordination, patch tracking, advisory writing) is part of the work; the chapters on it are the calmest treatment in print.
- Exploitation is a way of seeing programs, not a list of techniques.
- Memory corruption is best learned with a debugger open beside the book.
- The first half on C/assembly is worth the price even if you skip the exploits.
How they compare
We rate Hacking: The Art of Exploitation higher (5/5 against 4/5 for A Bug Hunter's Diary). For most readers, that means Hacking: The Art of Exploitation is the primary pick and A Bug Hunter's Diary is a useful follow-up.
Both books target intermediate-level readers, so the choice is about topic, not difficulty.
A Bug Hunter's Diary and Hacking: The Art of Exploitation both cover Offensive, so reading them in sequence reinforces the same material from different angles.
