What you’re looking at in the image above is a little device about the size of a cigarette packet running a piece of firmware known as “Jasager” (which over in Germany means “The Yes Man”) based on OpenWrt (think of it as Linux for embedded devices). Selling for only $100, it packs Wi-Fi capabilities, a USB jack, a couple of RJ45 Ethernet connectors and implements a kernal mode wireless feature known as “Karma”.
But why on earth would a victim connect to the Pineapple in the first place?! Well firstly, we’ve become alarmingly accustomed to connecting to random wireless access points whilst we’re out and about. When the average person is at the airport waiting for a flight and sees an SSID named “Free Airport Wi-Fi”, what are they going to do? Assume it’s an attacker’s honeypot and stay away from it or believe that it’s free airport Wi-Fi and dive right in? Exactly.
