Public Wi-Fi Attacks

You may not realize it, but a common risk of working remotely or working from the road is having to connect to and work within public Wi-Fi access points. These points might be the ones you’d find in your hotel, airport, or local coffee shop. But how secure are these public networks? Who could be watching or recording what you are doing online? While a shared or public Wi-Fi connection is incredibly convenient while on the go, you are taking a risk of exposing your personal data and company information.

Here are a couple of key behaviors to reduce that risk of data exposure for people traveling and accessing public Wi-Fi.

Stay Updated

Begin by ensuring that your browsers and plugins always have the latest patches and updates. Cyber attackers are constantly strategizing ways to detect new vulnerabilities in the software you use, and your vendors are constantly patching it. Current and updated systems are much more difficult for cyber attackers to hack into, so don’t ignore those system update recommendations. In many cases, enabling automatic updates is one of the simplest ways to ensure your system stays current and secure.

In addition, before installing any software, plugins, add-ons, or extensions, be sure to check your company’s policies and procedures to ensure the programs are authorized. If you are unsure, simply ask your help desk for guidance.


Encryption is a technology that helps protect your information when transmitted over the Internet. When you connect to public Wi-Fi points, you want to be sure all of your activity online is encrypted, ensuring others cannot monitor or capture what you do online. For example, when you’re browsing the web, you want to ensure your browser is connected to websites that are encrypted. Not sure if your browser connection is encrypted? Look to the top of your browser. If you see a padlock or HTTPS next to the website address, this is an indicator that your connection to the website is encrypted.

One of the simplest and most effective ways to encrypt all of your online activity is to use a Virtual Private Network (VPN). The technology behind a VPN creates a private, encrypted tunnel for your online activity, therefore making it much more difficult for anyone to watch or monitor your online activities. A VPN can also help hide your location, which makes it much more difficult for the websites you’re visiting to determine your precise location.


Wi-Fi tethering, also known as a mobile hotspot, refers to the action of connecting one device, such as a smartphone or a tablet, to another, such as a laptop, so that you may share the internet connection between devices when a Wi-Fi connection is unavailable. When in doubt about the security of a public Wi-Fi network, it is good practice to tether your network connection off of your smartphone instead of using the public Wi-Fi.

While this may not always be possible, especially when traveling internationally, it is one of the most secure methods to connect to Wi-Fi while traveling.


Ultimately you are the best defense. If something about the Wi-Fi connection seems odd or suspicious, simply don't connect. Find another Wi-Fi network you feel more comfortable with or tether from your mobile device. In addition, many of today’s online attacks are not targeting your technology but attempting to trick or fool you. If you receive an email, message, or phone call that seems odd or suspicious especially highly urgent ones, it may be an attack. Always be on alert.

Try to remember: Engage people with actionable behaviors that they can truly exhibit. A wonderful model to help you

understand the science behind behavior change is the BJ Fogg Behavior Model. This model indicates that three elements must touch at the same moment for a specific behavior to occur: Motivation, Ability, and a Prompt. When a behavior does not occur, it is the belief that at least one of those three elements is missing. Are you motivated to change behavior? Do you have the ability to change your behavior? Are you prompted to change your behavior?

It is unreasonable to tell people in the workplace to never use public Wi-Fi. And smacking them down with an overwhelming list of detailed steps to stay secure is not only impractical, but it can also have a negative impact on workplace productivity and data security. The goal is to manage your human risk by enabling people to secure themselves in ways anyone can follow. Next time you’re traveling and need to connect to Wi-Fi, try to keep these four simple key behaviors in mind. Your data and your company will thank you.
