The new series of Rip Off Britain – series nine! – began on BBC1 earlier this month and once again I’m appearing regularly as its resident tech expert.

In an episode earlier this week, I spoke with Angela about how high-tech car criminals can hack their way past keyless security systems. I also shared a few tips that may help concerned viewers stop their cars being stolen. Here’s a quick taster:

Car crime has largely moved on from the coat hanger and hot-wire days of old, with crime rates decreasing by 80 percent since 1993 according to the Office for National Statistics. However, a new wave of tech-savvy car criminals is now making easy work of making off with many makes of car.

I’ve been following the high-tech car crime trend closely, trying to understand the ways in which criminals are able to bypass or subvert car keyless security systems – whether through signal amplification, wireless jamming or keyless code capture. Criminals often steal to order, targeting high-value vehicles that are driven to so-called ‘chop-shops’ and sold on for parts.

Next week it’s up to Glasgow for BBC Rip Off Britain Live. I find the live shows particularly enjoyable because we are able to be responsive to news stories as they break. As such, I can’t say yet exactly which stories I’ll be covering, but I believe we’ll be discussing how the Internet of Things has made our homes vulnerable to hackers.

BBC Rip Off Britain airs on BBC1, weekdays 9.15-10.00. Watch here on BBC iPlayer.
