What started off nicely in 1992 and promised the much needed privacy to cordless communication at home, has been brought into a halt a few days ago with the practical approach to eavesdropping on DECT communication.

DECT or Digital Enhanced Cordless Telecommunication is a widely used standard for cordless devices, mainly phones, but not limited to it, several POS or Point of Sale devices as well use the standard to communicate in a cheap and secure manner.

The DECT standard itself was not broken, but rather using a cheap off-the-shelf device that is able to receive (not yet transmit) DECT based data, the researchers have been able to prove that eavesdropping on the communication channel is possible.

Most interesting to me as a reader of the paper is that what stopped people from ‘breaking’ it till now, was the lack of hardware, or moreover the lack of cheap hardware, to experiment with, now with the availability (it has been around for a while) of COM-ON-AIR device and its character device (or raw software driver) things have been made a lot easier.
