I want to install an application to audit the security of a wifi network.
By audit I mean discover whether current software can bypass my wifi password or read data being transferred.
I know there are some Linux distros that were designed specifically to do that, but I'm looking for an application I can install on Ubuntu.
You could try Airack-ng, it's built to pentest WiFi networks, be it encrypted using WEP, WPA, WPA2. As the site describes it:
It focuses on different areas of WiFi security:
Monitoring: Packet capture and export of data to text files for further processing by third party tools. Attacking: Replay attacks, deauthentication, fake access points and others via packet injection. Testing: Checking WiFi cards and driver capabilities (capture and injection). Cracking: WEP and WPA PSK (WPA 1 and 2).
There's also Wifite. It's less complicated than Aircrack-ng. You could just run it like sudo wifite, no arguments, and it'll scan for networks. Once you've seen the network you want to pentest, select it by entering its assigned number, then wifite will bruteforce it using different attacks. Personally, I use wifite if the WiFi network is WPS-enabled. Or to get the handshake capture of a WPA/WPA2 WiFi, then pass it along to Aircrack-ng for the dictionary attack.
