Deviant Ollam books.
Keys to the Kingdom, Impressioning, privilege escalation, bumping, and other key based attacks against physical locks 2012.
Got these 2 books in a trade, and am really impressed. Had heard of the books from Mr Anybody, and grabbed them quickly.
I cant say its ground breaking, esp the first book. But its so well written and easy to understand. It answer's all those questions you felt too stupid to ask. Great diagrams and photos, written in a friendly informative style by Deviant Ollam. It has lots for beginners, and experts alike.
It has chapters on pin tumblers an wafers, lots of info on picks and picking techniques. Bypassing, shimming, and bumping are explored in detail with lots of great pictures.
The second book contains much more stuff on impressioning, and the naughty stuff like key security and decoding and foil attacks. Im still struggling to take it all in, theres so much. Great info on mould attacks and casting keys.
Very pleased to own both, and they will remain in my bookcase for a long time. Not cheap, but worth the money.
