An interactive workshop. Pick a scenario and step through the protocol diagrams using the teaching CLI. Each scenario is fully self-contained — open the HTML file directly, no install required.
The same IMSI-catcher attack across three generations. It succeeds in 2G, is the whole point of the walk, and visibly fails in 5G. Learners feel the generational fix rather than reading it.
Threat-centric. Enumerate three 2G weaknesses, chain them into a downgrade-and-intercept attack, then replay each against 5G and watch them fail. Ends with an attack→mitigation map.
--suppress or --jam are teaching abstractions. Real-world downgrade attacks are subtler and gradual; we compress mechanics here so learners can see the effect in seconds.
