Packet injection allows for the attacker to interfere with an established network connection, by means of constructing packets to appear as if they are a normal part of the communication stream.
#How to use aircrack to sniff wifi password#
A lot of advanced wireless password cracking techniques use a technique called “packet injection”, also known as “packet spoofing”. With wireless cracking, there can be a big hardware limitation in some circumstances. Thankfully, the expansive features of Aircrack-ng allowed us to test multiple protocols and penetration test some very secure networks. We did not have a specific protocol that we wanted to test breaking (e.g. During the development of our project’s main focus we decided to use the program Aircrack-ng. When coming up with the idea for our project, we had a specific goal in mind: to test the efficacy of a wireless network cracking tool. In our implementation, we used Aircrack-ng in a completely command-line based environment on a physical machine. Aircrack-ng focuses on monitoring, attacking, testing, and cracking of wireless networks. Aircrack-ng is a complete set of tools made for assessing WiFi network security. We experimented with the program Aircrack-ng to assess its capabilities and to demonstrate its wireless password cracking features. Within this article, we will present how we set it up, what limitations we had to deal with, and show truly how much power Aircrack-ng has. We set up, used, and explored the popular wireless cracking program Aircrack-ng. The current methods of protecting wireless networks are only somewhat effective and the tools to break these methods are only getting stronger. With wireless networks being absolutely everywhere, there have to be some forms of protection against unwanted people gaining access.
