Pineapple creator Darren Kitchen described the device and detailed new capabilities. Kitchen explained that the original idea to build the Pineapple came from a desire to port the open-source Karma WiFi attack program to the FON (a small Fonera router).
The Pineapple has expanded since then and is now on its MarkIV hardware release, boasting a 400MHz Atheros AR9331 MIPS processor, 32MB of main memory and a complete 802.11 b/g/n stack.
When asked what version of Linux was running on the device, Kitchen said to think of the Pineapple as being its own Linux distribution, based somewhat on the OpenWRT Linux router project. –
