Public Wi-Fi: Convenience vs. Cybersecurity

We’ve all been there. You’re at a coffee shop, airport or hotel, and the temptation to connect to the free public Wi-Fi is strong. But before you tap “Connect,” consider the potential risks.

The Dangers of Public Wi-Fi

• “Evil Twin” Networks: Hackers can create fake Wi-Fi networks that mimic legitimate public Wi-Fi hotspots. These “evil twin” networks can intercept your data, including passwords, credit card information and other sensitive data.
  
  
• Data Exposure: Public Wi-Fi networks are often unsecured, meaning your internet traffic is not encrypted. This makes it easier for hackers to eavesdrop on your online activity and steal your information.
  
  
• Man-in-the-Middle Attacks: Hackers can position themselves between you and the legitimate Wi-Fi network to intercept and steal your data.

Tips for Staying Safe on Public Wi-Fi

• Use a VPN: A Virtual Private Network (VPN) encrypts your internet traffic, making it much more difficult for hackers to intercept your data.
  
  
• Avoid Sensitive Activities: Refrain from accessing sensitive accounts (banking, email, social media) or making online purchases on public Wi-Fi.
  
  
• Turn Off File Sharing: Disable file sharing and Bluetooth on your devices when connected to public Wi-Fi.
  
  
• Be Wary of Free Charging Stations: Public charging stations can sometimes be used to install malware on your devices.
  
  
• Consider a Personal Hotspot: If possible, use your phone as a personal hotspot for a more secure internet connection.

Remember: Public Wi-Fi is convenient, but it comes with inherent risks. By following these tips and exercising caution, you can minimize your exposure to cyber threats.
