Hacked is definitely one of my favourite podcasts at the moment, it's one of those that leaves you hanging for another episode after you finish because it's just so damn intriguing.

Just started listening. Sounds cool, but the WiFi providers have in Tube stations in London don't work on the trains when they're in motion between stations. You kind of have to try re-connecting every stop and it only lasts like 20 seconds before the train goes again...not sure it's really a threat zone...you'd notice if your phone remained connected and it would be super out of the ordinary. Unless you're a tourist, which is a definite possibility.
