Well done video leading up to cracking a WPA Wireless network utilizing John the Ripper and Aircrack-ng.
I love how Darren was sure to include that cracking WPA can take from a minute to 16 years… lol. Technically speaking, brute-force can crack anything if it goes undetected. For that reason, having complex passwords, that are not words in a dictionary, with lower and uppercase, numbers, and even special characters builds a security wall. It would literally take these brute-force programs years and years to forcibly hack your WPA Wireless network. Make your keys complex and change them often and you can get past people who are trying to get in.
