concept of hacking

In this tutorial learn about hackers ...

so now this tutorial will halp you to decide about arious hackers and classify them..

if you have any interset in hacking read it and learn something new..

      Hacking 
 
     •     Hacker is a computer person who is very curious and wants to learn as much as possible 
           about computer systems.  
     •     Hacking  was  developing  and  improving  software  to  increase  the  performance  of 
           computing systems. 
     •     Hacking has a  lot  of  meanings  depending  upon  the  person’s knowledge  and  his work 
           intentions. Hacking is an Art as well as a Skill. It is the knowledge by which one gets to 
           achieve his goals, anyhow, using his skills and power. 
 

Ethical Hacking         •     Ethical  Hacking  is  testing  the  resources  for  a  good  cause  and  for  the  betterment  of             technology.       •     Technically Ethical Hacking means penetration testing which is focused on Securing and             Protecting IT Systems.      Types of Hackers         •     White Hat Hacker       •     Black Hat Hacker       •     Grey Hat Hacker    White Hat Hacker         •     A  White  Hat  Hacker  is  computer  guy  who  perform  Ethical  Hacking.            These  are  usually  security  professionals  with  knowledge  of  hacking  and             the   hacker   toolset   and   who   use   this   knowledge   to   locate   security             weaknesses and implement counter measures in the resources.       •     They are also known as an Ethical Hacker or a Penetration Tester. They             focus on Securing and Protecting IT Systems.  Black Hat Hacker             •    A   Black   Hat   Hacker is   computer    guy    who    performs  Unethical    Hacking. These   are    the   Criminal   hackers   or Crackers   who  use   their   skills   and  knowledge   for   illegal  or  malicious purposes. They break into or otherwise vimalicious purposes. They break into or otherwise violate the system integrity of remote machines, with malicious intent.           •      These are also known as an Unethical Hacker  or a Security  Cracker. They focus on Security Cracking and Data stealing.    Grey Hat Hacker   •      A Grey Hat Hacker is a Computer guy who sometimes acts legally, sometimes in good will,  and sometimes not. They usually do not hack for personal gain or have malacious intentions, but may or may not occasionally commit crimes during the course of  their technological exploits.  •      They are hybrid between White Hat and Black Hat hackers.     Classification of Hackers            •      Coders          •      Admin          •      Script Kiddies    Coders    •      Coders are programmers  who  have  the  ability  to   find  the unique   vulnerability  in  existing  software  and  to  create  working exploit codes.    •      These  are  the  individuals with  a   deep  understanding  of  the  OSI Layer Model and TCP/IP Stacks.        Admin    •  Admin  the computer guys  who have  experience with  several  operating systems,  and  know how to exploit several existing vulnerabilities.        •      A majority of Security Consultants fall in this group and work as a part of Security Team. Script Kiddies Script  Kiddies  are  the  bunnies  who  use  script  and  programs developed by others to attack computer systems and Networks. They get the least respect  but are most annoying and dangerous and can  cause  big  problems  without  actually knowing  what  they are doing.    Steps Performed by a Hacker 1.   Performing Reconnaissance 2.   Scanning and enumeration 3.   Gaining access 4.   Maintaining access and Placing backdoors 5.   Covering tracks or Clearing Logs  Phase I: Reconnaissance Reconnaissance can be described as the pre-attack phase and is a systematic attempt tolocate, gather, identify, and record information about the target. The hacker seeks to find out as much information as possible about the target Phase II: Scanning and Enumeration >  Scanning  and  enumeration  is  considered  the  second  pre-attack  phase.  This  phase involves taking the information discovered during reconnaissance and using it to examine the network. > Scanning  involves  steps  such  as  intelligent  system  port  scanning  which  is  used  to determine open ports and vulnerable services. In this stage the attacker can use different automated tools to discover system vulnerabilities.   Phase III: Gaining Access   This is the phase where the real hacking takes place. Vulnerabilities discovered during the reconnaissance  and  scanning  phase  are  now  exploited  to  gain  access.  The  method  of connection the hacker uses for an exploit can be a local network,local access to a PC,the internet , or offline. Gaining access is known in the hacker world as owning the system. During a real security breach it would be this stage where the hacker can utilize simple techniques to cause irreparable damage to the target system. Phase IV: Maintaining Access and Placing Backdoors  >Once a hacker has gained access, they want to  keep that access for future exploitation and  attacks.  Sometimes,  hackers  harden  the  system  from  other  hackers  or  security personnel by securing their exclusive access with backdoors, rootkits, and Trojans. >The attacker can use automated scripts and automated tools for hiding attack evidence and also to create backdoors for further attack. Phase V: ClearingTracks   In this phase, once hackers have been able to gain and maintain access, they cover their tracks to avoid detection by security personnel, to continue to use the owned system, to remove evidence of hacking, or to avoid legal action.  At present, many successful security breaches are made but never detected. This includes cases where firewalls and vigilant log checking were in place.   also learn how proxy server works
