Wireless Hacking

What is Wireless?



Wireless communication is the transfer of information or power between two or more points that are not connected by an electrical conductor.

The most common wireless technologies use radio. With radio waves distances can be short, such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mice,keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones

Wireless Hacking 



An internet connection has become a basic necessity in our modern lives. Wireless hot-spots (commonly known as Wi-Fi) can be found everywhere! If you have a PC with a wireless network card, then you must have seen many networks around you. Sadly most of these networks are secured with a network security key. Have you ever wanted to use one of these networks? You must have desperately wanted to check your mail when you shifted to your new house. The hardest time in your life is when your internet connection is down. Hacking those Wi-Fi passwords is your answer to temporary internet access.


Now to hack a Wifi Password you must first know what type of encryption it uses for its passwords there are many different types such as: WEP (easiest to crack/hack), WPA and WPA2.


Types Of Encyption 

- WEP
- WPA
- WPA2

WEP

Wired Equivalent Privacy (WEP) is a security protocol, specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b, that is designed to provide a wireless local area network (WLAN) with a level of security and privacy comparable to what is usually expected of a wired LAN.

WPA


The Wi-Fi Alliance intended WPA as an intermediate measure to take the place of WEP pending the availability of the full IEEE 802.11i standard. WPA could be implemented through firmware upgrades on wireless network interface cards designed for WEP that began shipping as far back as 1999. However, since the changes required in the wireless access points (APs) were more extensive than those needed on the network cards, most pre-2003 APs could not be upgraded to support WPA.

The WPA protocol implements much of the IEEE 802.11i standard. Specifically, the Temporal Key Integrity Protocol (TKIP) was adopted for WPA. WEP used a 64-bit or 128-bit encryption key that must be manually entered on wireless access points and devices and does not change. TKIP employs a per-packet key, meaning that it dynamically generates a new 128-bit key for each packet and thus prevents the types of attacks that compromised WEP.

WPA2

WPA2 replaced WPA. WPA2, which requires testing and certification by the Wi-Fi Alliance, implements the mandatory elements of IEEE 802.11i. In particular, it includes mandatory support for CCMP, an AES-based encryption mode with strong security. Certification began in September, 2004; from March 13, 2006, WPA2 certification is mandatory for all new devices to bear the Wi-Fi trademark

Hack Ethically

About Me


I am an engineering student and i am very dedicated about Ethical Hacking. I have been learning "Ethical Hacking" for about 4 years now.
Though I'am not a pro hacker but also not a noob. I have enough knowledge to give others like me, a start for their Ethical Hacking & Cyber Security. As i keep learning new things, i keep updating them on the blog from basic to advanced level.
I started Ethical Hacking as a hobby which has now turned into my passion and i'am sure i will turn it into my profession through this blog.

Always be an Ethical Hacker.
