Fucking seriously?
I feel like he was asking what ebooks on "hacking" are worth reading, not where to find a huge list of ebooks, or a comprehensive guide to searching for them. Plenty of books you find will try to be too generic or entry-level imo. For instance, I've read some books with a title like "advanced low level exploitation" or something, and then you turn to chapter 1 and they're explaining what assembler is... At that point I am almost positive the book is going to be a waste of time. It may not be, but more often than not, its outdated and/or too much "intro".
We've discussed this in IRC a few times and some very knowledgeable people have chimed in. OP should also note that it depends on what you're trying to read about. If you're wanting to learn about windows internals, then the classic "Windows Internals 6th Edition" is good to at least have around, even if it's not the easiest to read front-to-back (who would've known...) If you're doing a wargame or something and you need to exploit a format string vuln or something similarly specific, google around some of the well-known hacking zines. Phrack comes to mind when it comes to low level shit.
Once you get to a point where you're tired of the basics, try and focus in on something like buffer overflows, and look up ways to defeat certain modern-day protections, imo you won't find these in a book because of how specific it is to the software/situation, you'll find more info through articles and writeups you can find online. Idk, maybe I'm full of shit and this adderall is just getting to me, but I've gone pretty far off-topic but the tl;dr is sometimes the best learning materials aren't in the form of books, because a lot of them kind of suck.
