Maurits Martijn writes: The idea that public WiFi networks are not secure is not exactly news. It is, however, news that can’t be repeated often enough. There are currently more than 1.43 billion smartphone users worldwide and more than 150 million smartphone owners in the U.S. More than 92 million American adults own a tablet and more than 155 million own a laptop. Each year the worldwide demand for more laptops and tablets increases. In 2013, an estimated 206 million tablets and 180 million laptops were sold worldwide. Probably everyone with a portable device has once been connected to a public WiFi network: while having a coffee, on the train, or at a hotel.
The good news is that some networks are better protected than others; some email and social media services use encryption methods that are more secure than their competitors. But spend a day walking in the city with Wouter Slotboom, and you’ll find that almost everything and everyone connected to a WiFi network can be hacked. A study from threat intelligence consultancy Risk Based Security estimates that more than 822 million records were exposed worldwide in 2013, including credit card numbers, birth dates, medical information, phone numbers, social security numbers, addresses, user names, emails, names, and passwords. Sixty-five percent of those records came from the U.S. According to IT security firm Kaspersky Lab, in 2013 an estimated 37.3 million users worldwide and 4.5 million Americans were the victim of phishing — or pharming — attempts, meaning payment details were stolen from hacked computers, smartphones, or website users.
Report after report shows that digital identity fraud is an increasingly common problem. Hackers and cybercriminals currently have many different tricks at their disposal. But the prevalence of open, unprotected WiFi networks does make it extremely easy for them. The Netherlands National Cyber Security Center, a division of the Ministry of Security and Justice, did not issue the following advice in vain: “It is not advisable to use open WiFi networks in public places. If these networks are used, work or financial related activities should better be avoided.”
Slotboom calls himself an “ethical hacker,” or one of the good guys; a technology buff who wants to reveal the potential dangers of the internet and technology. He advises individuals and companies on how to better protect themselves and their information. He does this, as he did today, usually by demonstrating how easy it is to inflict damage. Because really, it’s child’s play: The device is cheap, and the software for intercepting traffic is very easy to use and is readily available for download. “All you need is 70 Euros, an average IQ, and a little patience,” he says. I will refrain from elaborating on some of the more technical aspects, such as equipment, software, and apps needed to go about hacking people. [Continue reading…]
