I would like to share a book that might help you on a hacking/pentesting engagement.
It simulates a real hacking scenario from start to finish. From planting a small hardware in a store to spying on board meetings using custom scripts.
You can get a copy here : http://amzn.to/2oSPvQT
No metasploit, or pesky executables that trigger antivirus alerts or startup registry keys that any newbie admin can find...
Only neat opsec & up to date tricks (wmi, golden ticket, reflective dll injection, domain bouncing etc. )
You will mostly find Windows stuff but there is a dedicated section about Mainframe hacking (I find it fascinating that every so called hacking book skips over a technology that is at the heart of all major businesses in the world...)
Tell you what: you send me .pdf's of all three of your books, and they'll have DOZENS of reviews from unique accounts all over four years old, and which have made comments on many other products over those years.
