How to Recover Windows XP password using Cain & Abel

Introduction:-
Cryptography Decrypted                       In Your Windows XP, 7, VISTA, NT or 2000 system there is a file which store your system password. this file is sam(system account manager) which store all your account information (i.e., user name, password and user setting) and because password can't be saved as it is in a file because it can be hacked easily therefore Windows encrypt this password using a key(this key is stored in System file).
Both System and SAM file is stored at the same location i.e.,
C:\WINDOWS\system32\config
so to recover password we need both these file but because these file are locked so we can not use these file from window so we need other operating system to copy both these files let's say linux(because we can see windows drive in linux so you can go to above location and copy both sam and system file). if you don't have linux it's fine windows store these file in other location also i.e.,
C:\WINDOWS\repair
which Windows does not use so we can copy both files from this directory(but these file are created at the time of disk repair so there are chances that you may not get new password, if you changed your password recently)

How Do I Forward Internet Port(Port Forwarding)?

Introduction:-
Port forwarding refers to opening of closed port so that two or more application over internet can communicate with each other.You can think port as the way through which an application can communicate/reach to you that' why we need port 80 for http page telnet for 23 and ftp for 21.

Port forwarding for different modem/router is different but the theme remain the same in most modem/router.

WAY ONE
:-
  • Steps for port forwarding:-
  1. Go to your browser and type 192.168.1.1(default page for router/modem setting).
  2. In here type the username and password(commonly it is set to admin, admin).
    NOTE:- in case username and password is not admin then you can see it on the backside of your router/modem or can call your service provider.
  3. Now you will see the home page of your router in here click advanced link.
  4. in advanced page click port forwarding link which will take you to the page which is similar to the page shown below
    port forwarding forum of router/modem
    the page which you see above is present in almost all router/modem in addition to this some routers also provide you to forward ports directly for some common services like website(at 80), telnet(at 23), smtp(at 25) and many more.
    In here type
    • rule name :- any thing
    • protocol:- depending on port to forward(generally tcp/udp)
    • port start:-port to farward
    • port end:-same as port start
    • port map:- same as port start.
  5. Now apply the change and save all the setting so that after resetting your modem/router your setting remain the same.
WAY TWO:-

  • In case you are not able to forward port using the above defined technique or not able to find port forwarding link:-
  1. Go to google, yahoo or whatever search engine you use.
  2. Now in search box type port forwarding "company name of router/modem" "model no." To search the article regarding port forwarding for your router.
  3. In case you don't Understand the second point OR not able to search the article for your router then go to portforwarding.com and check some other router of the same company as your router for help.
    NOTE:-If even now you are not able to forward your ports then ask your ISP to do it for you.
