Yoofs today, no imagination.
Hack your moby, get your debit card details. Stalk you on faecesbook, know when you are out of your house/on holiday/at the pub and, from the geo tagging, how long it would take you to get back while the place is being burgled. Do the same with your heating/lighting controls, hack your 'smart' meter to run up your bill. Pass on your medical details to your insurance company to get you rated/declined, disclose your penicillin prescriptions to your significant other to undermine your personal life. Change the mileage on your 159 to 685,232 etc. etc.
