Episode 1: "The x.25 hacker" - Invented in the 1970s and popular in the
1980s, x.25 networks allowed some of the first computer systems to be globally
connected. At the time, x.25 networks were used by ATM machines, aviation companies,
e-mail systems, environmental control systems, news outlets, chemical companies,
banking and financial computers and much more. Globally connectivity and a wide
range of targets attracted hackers from around the world. In this episode,
we will be exploring and talking with x.25 hackers to learn how x.25 networks
functioned and how x.25 hackers exploited them.
This episode includes interviews by Da Beave, JFalcon and
Hans Heinrich Hubner (aka - "Pengo" from the "Cuckoo's Egg").

Want some old school reading material about x.25? Go to http://textfiles.com/hacking/" and search for "Telenet", "Datapac", "Tymnet", etc. There are many issues of Phrack that have information about x.25 networks.
