Julia, Gloria and Angela are back to host series seven of Rip Off Britain this September

The popular consumer affairs show starring Angela Rippon, Gloria Hunniford and Julia Somerville is now in its seventh series of helping viewers tackle rip offs and scams. I’m delighted to have been involved for the last four as a digital consumer champion across everything from cybersecurity and nuisance calls to mobile roaming and online safety.

For one film this season I took a detailed look at how safe we are when using the Public Wi-Fi hotspots increasingly found in coffee shops, airports and hotels. Even I was staggered at just how much information hackers can see on wireless networks with relatively little equipment or, frankly, expertise. This information can include unencrypted usernames, passwords and other sensitive details that can easily be used to execute identity fraud or phishing attacks.

This ‘digital eavesdropping’ might be the perfect crime, with coffee shop surfers quite unaware of a fraudster syphoning off valuable personal data on an adjacent table. The first they might realise something is amiss is when they get locked out of their social networking accounts or their email inexplicably starts spamming their address book.

During research for the show I uncovered some shocking security holes from well-known online and high-street retailers who really should know better. I also discovered how I wasn’t immune to sharing sensitive and valuable data by accident too.

Rip Off Britain airs every weekday on BBC1 for four weeks from Monday 14th September at 9.15am; see here for episode information and iPlayer links to watch on demand.
