Why you need to protect your privacy when using free Wi-fi
Mobile data is as essential as your Octopus card and your keys. You need it to browse online when you’re waiting for the bus, standing on the MTR, or waiting for a friend at the coffee shop.
So it’s really frustrating when you get that inevitable text every month that says you’ve used up all your data. You were only halfway through watching a YouTube video – what are you going to do now?
It’s no wonder then, that students are always keen to find a free Wi-fi hotspot.
But how do you know if the connection is safe? You’d probably assume it’s fine if you recognise the brand name on the network, because their reputation is pretty solid.
It’s a no brainer. You’ve got fast internet access for free. It’s easy to register with your email address, and bam, you can finally finish that video.
But it’s not that simple. You need to beware of these free hotspots, because they are not very secure, even if they require a password and Captcha verification. Data sent through a public Wi-fi system can be intercepted.
Some public hotspots can even be traps. They lure you in with the promise of free Wi-fi, but actually, connecting to the network will potentially allow people with bad intentions to access your device.
In these cases, your passwords can become useless because you’ve already opened the door and invited hackers in. Connecting to the Wi-fi was the key they needed. If your devices are not protected by a firewall or any antivirus software, it makes them even more prone to these kinds of invasions.
In a worst-case scenario, a hacker can easily take over your devices by sending seemingly normal file-sharing links and system upgrade alerts once you connect to their Wi-fi hotspots. If you open these links, unfortunately, your device could be infected by malware, and there will be no turning back.
