CEH v9 at 15 USD bundle-level is quite a joke, IMHO that should go to the 1 USD level but anyway as someone said Applied Cryptography might be the selling point here.

Personally speaking the only books valuable in this bundle are "Practical Reverse Engineering: x86, x64, ARM, Windows Kernel, Reversing Tools, and Obfuscation" and "Applied Cryptography: Protocols, Algorithms and Source Code in C, 20th Anniversary Edition" the other are either quite outdated, too oversimplified or script-kiddie level stuff.
