I'd suggest:

1.  GSM.  The phones were first cracked by Lucky Green back in 1998 as 
an academic demo, and a few years back I heard it was possible to buy 
crack devices.  I didn't follow up, but the existance of kits would 
indicate there was a market for paparrazi or minute-theft or PIs.

2.  chip & pin.  Look at the Cambridge lab work.  They've been involved 
in some legal cases, and there might be some verified crunches in there.

If you are doing research to document the state of real breaches, that 
would be valuable info.
