According to the researchers, all that's required is a souped-up 23-euro VoIP laptop card and a Linux computer. This setup has no difficulty in intercepting DECT conversations if, as is frequently the case, encryption is not activated. Even where data transfer is initially encrypted, the card is able to deactivate the encryption by pretending to be a base station...the goal of creating a sniffer that could be used from a car parked in front of a house, was achieved...PCMCIA card was, using a special Linux driver, able to eavesdrop on conversations, extract and write data to a storage medium and forward this data to an audio player. In such poorly secured DECT networks, it was possible to record every telephone conversation which took place.
some of you may recall that I have a bunch of these pcmcia card : something like 5 type III and 2 type II and all other ISDN/DECT equipment including DECT wireless lan hardware
I do hope to see my cards in action as DECT is very common and popular here in Europe
