Public Wi-Fi connections are everywhere – stations, shopping malls, coffee shops, hotels – any place where people spend time. Businesses have realised that providing free Wi-Fi to their customers is a great way to keep them in store for longer, spending money. As an added bonus, these free Wi-Fi networks can collect important information about your interests and preferences – data that can be used to create advertising campaigns that are tailored to you.
For many of us, public Wi-Fi networks are vital for staying connected to our family, friends, and co-workers. Unfortunately these networks also present a significant security risk.
Historically, the biggest risk to users has been so-called “man in the middle” attacks. At the most basic level, hackers are able to capture the information flowing across a public Wi-Fi network, allowing them to steal sensitive data like passwords and credit card numbers.
