Code BROWN in the Air presented at BSidesKnoxville 2017

by Stephen Hilt,

Summary : The talk is about the paging system, an old technology in the 90's, used in healthcare, ICS and government, a systematic review of security impacts that it brought to us in the age of SDR, covering the United States, Canada, England and Japan. By sniffing known pager frequencies in the general vicinity of hospitals, factories and public facilities with a $20 DVB-T, we discovered that not only is pager technology alive and kicking, but much of the traffic is not encrypted, resulting in violation of privacy laws and more importantly, leaks of sensitive information. The talk is not about the protocol nor the hardware device.
