Learn everything about ethical hacking
tools and skills
Skills allow you to achieve your desired goals
within the available time and resources. As a hacker, you will need to develop
skills that will help you get the job done. These skills include
learning how to program, use the internet, good at solving problems, and taking
advantage of existing security tools.
In this article, we will introduce
you to the common programming languages and skills that you must know as a
hacker. We will also look at tools that you can use to identify and
exploit security weaknesses in computer systems.

Summary
A programming language is a language
that is used to develop computer programs. The programs developed can range
from operating systems; data based applications through to networking
solutions.
·
Hackers are problem solver and tool
builders, learning how to program will help you implement solutions to
problems. It also differentiates you from script kiddies.
·
Writing programs as a hacker, will help
you to automat many taskswhich would usually take lots of time to complete.
·
Writing programs can also help you
identify and exploit programming errors in applicationsthat you will be
targeting.
·
You don’t have to reinvent the wheel all
the time, there are a number of open source programs that are readily usable.
You can customize
the already existing applications and adding your own methods to suit your
needs.
The answer to this question depends on your target computer systems
and platforms. Some programming languages
are used to develop for only specific platforms. As an example, Visual Basic
Classic (3, 4, 5, and 6.0) is used to write applications that run on windows
operating system. It would therefore be illogical for you to learn how to
program in Visual Basic 6.0 when your target is hacking Linux based systems.

PLATFORM
|
PURPOSE
|
1
|
HTML
|
Language used to write web pages.
|
*Cross platform
|
Web hacking
Login forms and other data entry methods on the web use
HTML forms to get data. Been able to write and interpret HTML, makes it easy
for you to identify and exploit weaknesses in the code.
|
2
|
JavaScript
|
Client side scripting language
|
*Cross platform
|
Web Hacking
JavaScript code is executed on the client browse. You can
use it to read saved cookies and perform cross site scripting etc.
|
3
|
PHP
|
Server side scripting language
|
*Cross platform
|
Web Hacking
PHP is one of the most used web programming languages. It
is used to process HTML forms and perform other custom tasks. You could write
a custom application in PHP that modifies settings on a web server and makes
the server vulnerable to attacks.
|
4
|
SQL
|
Language used to communicate with database
|
*Cross platform
|
Web Hacking
Using SQL injection, to by-pass web application login
algorithms that are weak, delete data from the database etc.
|
5
|
Python
Ruby
Bash
Perl
|
High level programming languages
|
*Cross platform
|
Building tools & scripts
They come in handy when you need to develop automation
tools and scripts. The knowledge gained can also be used in understand and
customization the already available tools.
|
6
|
C & C++
|
High level programming
|
*Cross platform
|
Writing exploits, shell codes etc.
They come in handy when you need to write your own shell
codes, exploits, root kits or understanding and expanding on existing ones.
|
7
|
Java
CSharp
Visual Basic
VBScript
|
Other languages
|
Java & CSharp are *cross platform. Visual Basic is
specific to windows
|
Other uses
The usefulness of these languages depends on your
scenario.
|
* Cross platform means programs
developed using the particular language can be deployed on different operating
systems such as Windows, Linuxed based, MAC etc.
In addition to programming skills, a
good hacker should also have the following skills:
·
Know
how to use the internet and search engines effectivelyto gather information.
·
Get a Linux based operating system and the know the basics commands that every Linux user
should know.
·
Practicemakes perfect, a good hacker should be hard working and
positively contribute to the hacker community. He/she can contribute by
developing open source programs, answering questions in hacking forums etc.
They are computer programs and scripts
that helps you find and exploit weaknesses in computer systems. Some of these
tools are open source while others are commercial.
The following table lists some of the
most commonly used tools.
