One
thing any hacker should know is how to hack into login account of any
operating system. Major Operating Systems that are used these days are
Windows, Linux and Mac. So today I will show you how to hack into these
Operating Systems. Are you curious how easy it is for someone to gain
access to your computer? If so, read on to see the technique one might
use to figure out your computer password.
Windows
Windows
being very popular has a lot of programs available which can be used to
hack the login password. One of the most successful program is
Ophcrack, and it is free. Ophcrack is based on Slackware, and uses
rainbow tables to solve passwords up to 14 characters in length. The
time required to solve a password? Generally 10 seconds. The expertise
needed? None.
Simply
download the Ophcrack ISO and burn it to a CD (or load it onto a USB
drive via UNetbootin). Insert the CD into a machine you would like to
gain access to, then press and hold the power button until the computer
shuts down. Turn the computer back on and enter BIOS at startup. Change
the boot sequence to CD before HDD, then save and exit.
The
computer will restart and Ophcrack will be loaded. Sit back and watch
as it does all the work for your. Write down the password it gives you,
remove the disc, restart the computer, and log in as if it were you own
machine.
You can download OphCrack from the following link:

Linux
Linux
is an operating system which is quickly gaining popularity in
mainstream, but not so common that you’re likely to come across it.
Though Mac and Linux are both based on Unix, it is easier to change the
password in Linux than it is OS X.
To
change the password, turn on the computer and press the ESC key when
GRUB appears. Scroll down and highlight ‘Recovery Mode’ and press the
‘B’ key; this will cause you to enter ‘Single User Mode’.
You’re
now at the prompt, and logged in as ‘root’ by default. Type ‘passwd’
and then choose a new password. This will change the root password to
whatever you enter. If you’re interested in only gaining access to a
single account on the system, however, then type ‘passwd username’
replacing ‘username’ with the login name for the account you would like
to alter the password for.
Mac
Finally
we take on Mac’s OS X which as we said earlier is based on Unix and is
difficult to change password compared to Linux but nothing is
impossible to be hacked.
The
easiest method would be to use Ophcrack on this also as it works with
Mac and Linux in addition to Windows. However, there are other methods
that can be used, as demonstrated below.
If
the Mac runs OS X 10.4, then you only need the installation CD. Insert
it into the computer, reboot. When it starts up, select UTILITIES >
RESET PASSWORD. Choose a new password and then use that to log in.
If the Mac runs OS X 10.5, restart the computer and press COMMAND + S. When at the prompt, type:
fsck -fy
mount -uw /
launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist
dscl . -passwd /Users/UserName newpassword
That’s it. Now that the password is reset, you can login.
