Common dangers of using public Wi-Fi and why it is high risk 🖥️📱📡

Using public Wi-Fi can be risky because it’s often not very secure. Whether you’re going to the airport or the coffee shop, these Wi-Fi safety tips can help protect your data from bad actors.

Earlier this month it was reported that criminals were targeting Australian airports and planes, using a simple device they can buy on eBay for $20, to create fake Wi-Fi networks to steal data from unsuspecting users (read article by The Australian).

When you’re outside the home, you might need to connect to a wireless network at places like a coffee shop, an airport, a mall, or even in a vehicle. The problem with using these public networks is that you can’t be sure if they’re safe. This is especially important if you’re using your phone or laptop for important things like checking your bank account or logging into your email.

Public wireless networks are open to everyone, so you don’t know who else is connected at the same time. If you’re sending sensitive information, like passwords or bank details, someone with bad intentions could be on the same network trying to steal your information. Once they have your details, they can misuse them to steal your identity or take money from your bank account.

That’s why it’s very important to be careful when using public wireless networks. Always use caution to protect your personal information. If you are unsure of the security of a public WiFi, it’s always recommended to check with a friend or family member before connecting.

Handy Hint: Common Wi-Fi networks that are fake

Hackers often create fake Wi-Fi network names that sound legitimate to trick people into connecting. This might be based on your location or the keyword “free”. Some common names used for these fake networks include:

Free Public Wi-Fi
CoffeeShop_WiFi
Airport_WiFi
Hotel_WiFi
Library_WiFi
Free_Internet
Guest_WiFi
Restaurant_WiFi
Open_WiFi
Mall_WiFi

These names mimic those of legitimate networks you might expect in public places. To stay safe, always verify the network name with the staff or look for official signage before connecting. Also pay close attention to the letters and any numbers or symbols that replace the letter (just like with email sender names). Example, if you are staying at the Novotel Hotel and there is a Wi-Fi networking available as “Nov0tel_WFi_Guest” or “Free_1nternet” with the number 1 instead of a capital I.

If in doubt, it’s better to avoid connecting altogether or use a VPN for added security.

Common Dangers of using public Wi-Fi on your mobile or laptop

Whether you’re on a laptop or on your mobile, using public Wi-Fi can be risky because it’s often not very secure. Here are some common dangers:

Data Theft: Hackers can easily see the information you send over public Wi-Fi.
Fake Wi-Fi Networks: Some hackers create fake Wi-Fi networks to steal your information.
Viruses and Malware: You could accidentally download harmful software from public Wi-Fi.
Unsecured Networks: Many public Wi-Fi networks don’t protect your data, making it easy for hackers to access it.
Account Hijacking: Hackers can take over your online accounts if they get your information from public Wi-Fi.

Five things to know before connecting to a public Wi-Fi network

Use a VPN (Virtual Private Network): A VPN is a tool that helps protect your internet connection. Ask a tech-savvy friend or family member to set one up for you. (Note sure what a VPN is or does? Scroll to the end of the article to watch a short explainer video)
Check the Network Name: Make sure you are connecting to the right network by asking the staff of the place you’re in. Avoid networks with names like “Free Wi-Fi.”
Turn Off File Sharing: Before connecting, make sure your device is not set to share files. This can usually be done in the settings or preferences on your device. If you need help, ask someone you trust.
Look for HTTPS: When visiting websites, check for “https” at the beginning of the web address. This means the site is more secure.
Avoid Sensitive Activities: Don’t do things like online banking or shopping when you’re on public Wi-Fi. Save those activities for when you’re at home on a secure network.

Andrea Coleman, an AFP cyber crime detective inspector, said the case highlighted why people should be careful when using public Wi-Fi networks.

“To connect to a free Wi-Fi network, you shouldn’t have to enter any personal details, such as logging in through an email or social media account,” she said.

“If you do want to use public Wi-Fi hotspots, install a reputable virtual private network (VPN) on your devices to encrypt and secure your data when using the internet.”

Coleman said when using a public Wi-Fi network, people should also avoid doing anything sensitive, such as file sharing or banking.

“We also recommend turning off the Wi-Fi on your phone or other electronic devices before going out in public, to prevent your device from automatically connecting to a hotspot,” she said.

Coleman said she always encouraged people to strengthen their passwords, make each password unique, use a password manager and install all available software and security updates on their devices.

Case Study: The Dangers of Fake Wi-Fi Networks

Background:
John, a 65-year-old retiree, frequently visited his local coffee shop to read and check his emails using their free Wi-Fi. Unbeknownst to John, a hacker named Alex set up a fake Wi-Fi network named “CoffeeShop_FreeWiFi” which was almost identical to the legitimate network’s name.

Incident:
One day, John connected to “CoffeeShop_FreeWiFi” instead of the legitimate network. Alex, the hacker, was able to see all the information John sent over this fake network. This included personal emails, login details for his bank account, and even his social media passwords.

Consequences:

Identity Theft: Alex used John’s personal information to steal his identity. This led to unauthorized transactions in John’s bank account.
Email Compromise: Alex accessed John’s email account and sent phishing emails to John’s contacts, spreading the attack further.
Social Media Hijacking: Alex posted malicious links on John’s social media, tricking John’s friends and family into clicking them.

Resolution:
John noticed unusual activity in his bank account and on his social media. He contacted his bank immediately, which froze his account and started an investigation. John also contacted his email and social media providers to regain control of his accounts.

John had to go through a lengthy process to restore his identity and secure his accounts. He also learned about the importance of verifying Wi-Fi networks and taking precautions when using public Wi-Fi.

Lessons Learned:

Always Verify Network Names: Ensure you are connecting to the correct network by asking staff for the exact name of their Wi-Fi.
Use a VPN: A VPN can provide an extra layer of security. If unsure how to set one up, ask a trusted friend or family member.
Be Cautious with Personal Information: Avoid accessing sensitive information such as banking or personal accounts when using public Wi-Fi.
Monitor Your Accounts: Regularly check your bank and online accounts for any unusual activity.

By learning from John’s experience, you can better protect yourself from the risks of using public Wi-Fi. Always be cautious and take the necessary steps to ensure your online safety. If you’re ever in doubt, ask for help from someone you trust.

By understanding these risks and taking simple precautions, you can use public Wi-Fi more safely. If you’re unsure about any of these steps, ask a trusted friend or family member for help.
