Hacker
The meaning of Hacker is one who accesses a computer which is supposably not able to be accessed to non
authorised people of the community. Hackers may use any type of system to access this information
depending on what they intend on doing in the system.
Methods
Hackers may use a variety of ways to hack into a system. First if the hacker is experienced and smart the
hacker will use telnet to access a shell on another machine so that the risk of getting caught is lower than
doing it using their own system.
Ways in which the hacker will break into the system are:
1) Guess/cracking passwords. This is where the hacker takes guesses at the password or has a crack
program to crack the password protecting the system.
2) Finding back doors is another way in which the hacker may get access to the system. This is where the
hacker tries to find flaws in the system they are trying to enter.
3) One other way in which a hacker may try to get into a system is by using a program called a WORM.
This program is specially programmed to suit the need of the user.
