BSides Talk: It’s 2020, so why am I still able to read your pager traffic?

At the BSides OK 2020 virtual conference Cameron Mac Millan recently presented a talk titled "It’s 2020, so why am I still able to read your pager traffic?". On this blog we have posted numerous times about privacy breaches stemming from insecure wireless pager traffic. Anyone with a radio or SDR can receive and decode pager messages, and this has been known and done since the 1980's. Cameron's talk explains how paging systems work, who are the modern users of pagers, how to capture and decode pager messages and how to best log and filter through messages. He goes on to describe a number of major pager security breaches that he's personally seen. The talk preview reads:

This talk explores why pagers remain a potential threat vector in many environments despite the technology being 40 years old. This is not a the-sky-is-falling presentation: everything from paging history to how simple it is to decode pager traffic (and the associated risks) is covered without FUD.

I enjoy poking things with sticks and turn over rocks to see what crawls out from under them. One of my interests is seeing how technologies believed to be obsolete can still pose a problem for security today, and do that from the perspective of a 20-year career in infosec. When not creating tomorrow’s problems with yesterday’s technology, I can usually be found wrenching on unusual cars.
