Aircrack Ng

Welcome back, my greenhorn hackers. When Wi-Fi was first developed in the late 1990s, Wired Equivalent Privacy was created to give wireless communications confidentiality. WEP, as it became known, proved terribly flawed and easily cracked. You can read more about that in my b ...more

Welcome back, my rookie hackers! When Wi-Fi was first developed and popularized in the late '90s, security was not a major concern. Unlike wired connections, anyone could simply connect to a Wi-Fi access point (AP) and steal bandwidth, or worse—sniff the traffic. The first a ...more
