Wireless Attacks Unleashed

As we all know, wireless networks are spread at each and every part of the world, starting from personal home to corporate business environments, schools/universities, cafes, etc. The major merit of wireless networking is to eliminate the big and untidy cables, which acquires space and unspoils the look of your working area. But as we all know, each coin has two sides. There are demerits of wireless networking as well. It comes with high possibility of attacks on it. In this article I am going to describe different techniques of attacks on wireless networks and what we should do to prevent them.

Let’s start with WLAN protocol, which is also known as 802.11 protocol, commonly used for wireless networking. The major function of this protocol is to link more than one device. It uses spread spectrum signals. The functionality of these signals is based on radio frequency communication where networking is established between two point-to-point end devices consisting of a transmitter and a receiver. In this mechanism, participants (in terms of end devices) must have transmitters and receivers to send and receive signals.

To connect to the wireless network, each participant must have wireless AP (Access Point – also known as Wi-Fi hot-spot) along with the wireless adaptor. The AP acts as a walkie-talkie. It converts radio signals into digital signal and vice-versa. When AP transmit the signals, those signals have SSID, known as service set identifier & information of network identification. The receiver detects the signals and lists the available wireless network around him/her, along with the signal strength. Not only this, it also identifies whether the AP is using any security, and if yes, then what is the level of security. As its wireless network, it allows more than one node to let those nodes connect with the network, so that is why authentication is important to ensure there is not any malicious Internet user lying in that network. The AP holds this responsibility.

Wardriving at Delhi Updated: Access Points with no security

I got an overwhelming response to my Wardriving at Delhi project and have got a lot of emails regarding the same. I am so thrilled that so many people want to contribute to the project. Inspired by your feedback, I am here by producing here an update to my mapping project. This time I went Via Saket to Gurgaon and as usual I got a lot of access points which were OPEN with no security, WEP secured vulnerable access points & WPA/WPA PSK2 secured points.

 
As usual, I used -

• Kismet
• Moocherhunter
• Aircrack
• G-MON & WiGLE

The target is to make a map of Delhi with all the access points  to analyse in layman terms -

1. The security awareness of people and organizations
2. The devices they are using
3. The security mechanisms they are using.
4. Wifi range analysis of individual device.

Well, in all you can find the data from below links -

• Hotspot details / BSSID (See if you are on the list) =))
• Google Maps KML Data (See it in Google Maps)

If you are interested in contributing to the data, please contact me at admintheprohack.com . You can also read how to Hack Wifi using Backtrack , How to detect if someone is using your WiFi  or how to detect WiFi hotspots . If you are having an Android, you can also read about how to use your Android for Wardriving.

Happy Wardriving.

Wireless has become ubiquitous in today’s world. The mobility and flexibility provided by it makes our lives more comfortable and productive. But this comes at a cost – Wireless technologies are inherently insecure and can be easily broken. BackTrack is a penetration testing and security auditing distribution that comes with a myriad of wireless networking tools used to simulate network attacks and detect security loopholes.

Backtrack 5 Wireless Penetration Testing Beginner’s Guide will take you through the journey of becoming a Wireless hacker. You will learn various wireless testing methodologies taught using live examples, which you will implement throughout this book. The engaging practical sessions very gradually grow in complexity giving you enough time to ramp up before you get to advanced wireless attacks.

This book will take you through the basic concepts in Wireless and creating a lab environment for your experiments to the business of different lab sessions in wireless security basics, slowly turn on the heat and move to more complicated scenarios, and finally end your journey by conducting bleeding edge wireless attacks in your lab.

There are many interesting and new things that you will learn in this book – War Driving, WLAN packet sniffing, Network Scanning, Circumventing hidden SSIDs and MAC filters, bypassing Shared Authentication, Cracking WEP and WPA/WPA2 encryption, Access Point MAC spoofing, Rogue Devices, Evil Twins, Denial of Service attacks, Viral SSIDs, Honeypot and Hotspot attacks, Caffe Latte WEP Attack, Man-in-the-Middle attacks, Evading Wireless Intrusion Prevention systems and a bunch of other cutting edge wireless attacks.

If you were ever curious about what wireless security and hacking was all about, then this book will get you started by providing you with the knowledge and practical know-how to become a wireless hacker.

Hands-on practical guide with a step-by-step approach to help you get started immediately with Wireless Penetration Testing

What you will learn from this book :

-Create a Wireless Lab for conducting experiments
-Monitor the air and sniff wireless packets
-Bypass WLAN authentication mechanism
-Crack WEP/WPA/WPA2 encryption mechanisms
-Break into a WLAN network using infrastructure flaws
-Break into a Wireless client such as a laptop
-Advanced attacks such as Man-in-the-Middle attacks and Evading WIPS
-Conduct wireless penetration test in a methodical way

Boost Your Wi-Fi Signals With Beer Cans

I love a good hack, especially one that requires me to throw back a cold one before hand (or during). This simple wifi boost has actually been shown to increase signal strength by at least 2 to 4 bars. And, well, I will drink to that.

These instructions came to us via The Chive and we think they are most definitely worth checking out. But here is the most important question: what kind of beer will you use?

For this project you are going to need scissors, a utility knife, some adhesive putty and an empty beer can. More than one empty beer can is acceptable but don’t kid yourself, the router only needs the one.

The first step is to wash out your empty beer can, unless of course said beer is a can of Pabst Blue Ribbon. If it is PBR, promptly go drink a better beer. You really should be ashamed of yourself.

Once the can has dried, you will want to remove it’s pull tab.

Only perform this next step if you have not been drinking. Using the utility knife, saw off the bottom of the can. Chances are your can will not have a red dotted line. If you see one, put down the knife…you’ve had too much beer.

You’ll notice in the above step that the can’s pull tab has returned. Clearly, there are only two possible reasons for this. One, you are really drunk and you never removed the tab in the first place. Or–the more likely answer–beer cans can regenerate themselves.

It’s the home stretch! You just need to attach your modded beer can to the wifi router. Hopefully no other parts of the can have actually grown back. You now have beer-fi!

So, what kind of beer did you use?
