Exrop - Automatic ROP Chain Generation

@Hacking_Video

Exrop is automatic ROP chains generator (https://www.kitploit.com/search/label/Generator) tool which can build gadget chain automatically from given binary and constraints Requirements : Triton (https://github.com/JonathanSalwan/Triton), ROPGadget (https://github.com/JonathanSalwan/ROPgadget) Only support for x86-64 for now! Features: handling non-return gadgets (https://www.kitploit.com/search/label/Gadgets) (jmp reg, call reg) set registers (rdi=0xxxxxx, rsi=0xxxxxx) set register to register (rdi=rax) write to mem write string/bytes to mem function call (open('/etc/passwd',0)) pass register in function call (read('rax', bss, 0x100)) avoiding badchars stack pivoting (https://www.kitploit.com/search/label/Pivoting) (Exrop.stack_pivot) syscall (Exrop.syscall) see examples (https://github.com/d4em0n/exrop/blob/master/examples)
Installation install python (3.6 is recomended and tested) install triton (https://triton.quarkslab.com/documentation/doxygen/index.html#linux_install_sec), make sure you add -DPYTHON36=on as cmake option install ropgadget (https://www.kitploit.com/search/label/ROPgadget) (https://github.com/JonathanSalwan/ROPgadget) to install exrop, easily add export PYTHONPATH=/path/to/exrop:$PYTHONPATH in your .bashrc (depends on your shell) Demo from Exrop import Exrop

How to take ethical revenge on extortion scammer?

I know it’s a little off topic but yesterday I checked my spam and saw an extortion email(with an outdated password I haven’t used for long) and I was wondering what can I do to revenge, some people might fall for it and maybe I can do my part. Any help is greatly appreciated!

Aspiring ethical hacker here, how much of networks should I know?

I know that I should not only know about networks but also programming, Linux, Windows to get a solid base before studying how hacking works. I am watching the same videos that people watch to pass the Cisco certification and using flashcards. Should I prepare like I were going to pass Ciscos test? Or just get to know about networks superficially with a handful of videos or a short guide? Any recommendations? Also, I plan just to become a bounty hunter of vulnerabilities, and just do it as a hobby.
