How safe are London’s Wi-Fi hotspots? See the results of our warbiking ride (Video)

Warbiking LondonOur World of Warbiking tour cycled through London, UK, where we surveyed the Wi-Fi networks people use everyday as they move about the city, connecting on their laptops and mobile devices. What we found is an enormous lack of security.

The warbiking project involves traveling around the globe, riding the streets of major cities with my computer-equipped mountain bike, and looking for wireless connections along the way to sneak a peek at the companies and regular people who are using them. (Don’t worry, it’s all perfectly legal.)

What we found is somewhat alarming, if not downright scandalous. People in London, much like their counterparts in San Francisco, are all too happy to connect to unsecured wireless networks, without using encryption. It’s an invitation for a cybercriminal to do harm, even though many people don’t even know it.

Most Wi-Fi networks we surveyed in London used outdated or no encryption

By now we all should appreciate that encryption is a must-have if you want to keep your personal data safe.

Out of 81,743 networks surveyed on our tour of London, some 29.5% were using either the known-broken Wired Equivalent Privacy (WEP) algorithm, or no security encryption at all. A further 52% of networks were using Wi-Fi Protected Access (WPA) — a no longer recommended security algorithm.

Only a paltry 17% of Wi-Fi networks we scanned were using the recommended WPA2 encryption.


Would you trust a network called DO NOT CONNECT?

When we set up an open wireless network in a busy part of London, lots of people connected to our network, even when we called it DO NOT CONNECT. Most connected to the Internet without using encryption, even when visiting really important websites like their webmail, social networks, and banking websites.

What many of these normally tech-savvy people don’t appreciate is that whenever you connect to a network, the owner of that network could insert code on your computer or redirect you to a malicious website.

If you use a VPN your information is encrypted as it crosses the web, so it’s safe from any attacker. Sadly, only 2% of people connecting to our hotspot used a VPN.


10 wireless security tips

Even though many people get security wrong, that doesn’t mean it has to be difficult. There are lots of easy ways to improve your security. I urge you to read these 10 tips to learn more:
