Behind the Signal: Finding Hidden SSIDs with Kali Linux (Pt. 2)

Finding an unadvertised Wi-Fi network name is a narrower result than demonstrating that the network is vulnerable. A hidden service set identifier (SSID) changes some management-frame advertisements; it does not encrypt traffic, authenticate a client or confer secrecy on the wireless channel. The purpose of this second-stage Kali Linux investigation is to interpret what an… Read More »

Ettercap and SSLstrip: Preventing Network MITM Attacks

Ettercap and SSLstrip are closely associated with historical demonstrations of man-in-the-middle attacks. They highlight two different trust problems: a local network can be deceived about which system should receive traffic, and a browser can be steered away from a protected connection when the security upgrade is not enforced. For network owners, the practical task is… Read More »
