Vol.1 Information Gathering
Introduction :
Information gathering considered the most important part at our journey of bug hunting , it means  we should collect as much as you can of information's about your target in order to be able to hack it.
and to get results from multiple places at once , more information's equal to more opportunity to get what you want from your target it's considered the Black Magic art that every hacker should master

my plan is to dive with you into this big topic and cover as much as i can from it and teach you the technics and tricks and show you example of methodology of information gathering art so you can preform it in understandable manners.

Methodology :

this is changeable by the target you work on this means not all targets should be treated the same way some websites you will start with enumeration the subdomains as your first step and other targets you may start with brute-forcing directory's and hidden files so don't take this as typical just use your intellect but in general we will do :
  • Discover target subdomains
  • Determine the target ip
  • [b]Discover the open ports and running services[/b]
  • Fingerprint the OS
  • Discover folders and Hidden content
  • Collect staff e-mails

Tools :
  • Dnsdumpster ( Subdomain enumeration tool )
  • Nmap ( Network Mapper)
  • DirBuster ( Multi-threaded Directory/Files Brute-forcing Tool )
  • The Harvester ( scrap website e-mails )

Most of the time when you enumerate the subdomains also be able to define the real ip of the target and sometimes not so don't take it as promise.

  • Discover Hosts
  • Scanning Open Ports
  • Version Detection
  • TCP/IP Stack Fingerprinting
  • Script system that interact with the targeted device

Basic Nmap Cheat Sheet :

nmap -p 1-65535 -sV -sS -T4 target |  Full TCP port scan using with service version detection

nmap -v -sS -A -T4 target | Prints verbose output, runs stealth syn scan, T4 timing, OS and version detection + trace route and scripts against target services.

nmap -v -sV -O -sS -T5 target | Prints verbose output, runs stealth syn scan, T5 timing, OS and version detection.

nmap -v -p 1-65535 -sV -O -sS -T4 target | Prints verbose output, runs stealth syn scan, T4 timing, OS and version detection + full port range scan.
