Airport Wifi: Is Your Data At Risk?

Free airport WiFi is convenient, but it may come at a cost. Public WiFi networks are often untrusted and unsecured, making it easy for hackers to access your device and personal information. A recent study by cybersecurity company Coronet found that most airport public networks are unencrypted, insecure, or improperly configured, leaving travellers vulnerable to data breaches and identity theft.

While airports are adept at handling physical security, digital security is another matter. Airports are a tempting target for cybercriminals due to the high volume of users accessing sensitive information. This makes it crucial for travellers to take precautions when using airport WiFi to protect their data and devices.

Public WiFi is an untrusted network

One common tactic used by hackers is to set up "evil twin" networks with names similar to legitimate WiFi networks. For example, a hacker might set up a network called "GoodNight Inn," hoping that users will mistake it for the legitimate "Goodnight Inn" network. By connecting to these fake networks, users risk granting hackers access to their internet traffic.

Another risk associated with public WiFi is the man-in-the-middle (MITM) attack, where an intruder secretly positions themselves between two communicating parties. On unsecured public WiFi networks, attackers can more easily capture data packets, gaining access to sensitive information. Additionally, malware distribution is a concern, as bad actors can exploit vulnerabilities in your device's software to install malicious programs without your knowledge.

To protect yourself when using public WiFi, it is recommended to use a virtual private network (VPN) to encrypt your data. Other precautions include avoiding accessing sensitive information, sticking to "HTTPS" websites, using privacy-focused browser extensions, and disabling automatic connection to unsecured public hotspots. It is also important to use strong, unique passwords and enable two-factor authentication whenever possible.

While the widespread use of encryption has made connecting through public WiFi safer than in the past, it is still important to take precautions to protect your personal information.

Use a Virtual Private Network (VPN)

Using a Virtual Private Network (VPN) is a great way to protect your data when using free airport Wi-Fi. A VPN encrypts your data and hides your IP address, making it difficult for hackers to spy on your online activity. It also helps protect the information your IP address can reveal. For example, advertisers can use your IP address to target you with ads.

A VPN is a secure and private solution that allows you to send and receive data while maintaining the secrecy of a private network. It does this by redirecting your internet connection through a private internet server. This means that even if you are connected to an unsecured network, your connection is still secure.

There are many different VPNs to choose from, including Mozilla VPN, NordVPN, Proton VPN, IP Vanish, and Firefox's VPN. It is important to choose a trustworthy VPN to ensure your data is protected.

While a VPN can help protect your data, it is also important to take other precautions when using free airport Wi-Fi. For example, it is recommended to forget the network after you are finished using it to prevent your device from automatically reconnecting without the VPN. Additionally, it is important to use antivirus software, avoid entering sensitive information, and be cautious when browsing the internet.

Avoid accessing sensitive information

While it may be tempting to check your bank account or log in to your email when using airport Wi-Fi, this is best avoided. Since you never know if a public Wi-Fi network has been compromised, accessing sensitive information could give a hacker access to your financial or personal information.

If you need to access sensitive information, it's best to use your mobile hotspot or a Virtual Private Network (VPN). A VPN encrypts your internet connection and allows you to use public Wi-Fi safely by creating an extra layer of security. This makes it much harder for hackers to intercept your data.

If you must use airport Wi-Fi, confirm the name of the network with airport staff before connecting. Look-alike Wi-Fi networks are a common way for hackers to gain access to your data.

Additionally, ensure your online accounts are secure by using strong passwords and enabling Multi-Factor Authentication (MFA) wherever possible. A strong password has at least 16 characters consisting of a combination of uppercase and lowercase letters, numbers, and symbols. MFA requires an extra form of identification, such as a fingerprint, your geographic location, or a unique answer to a security question.

By following these precautions, you can help protect your sensitive information when using airport Wi-Fi.

Use a password manager

Free airport WiFi is convenient, but it comes with serious risks to your digital safety. Airports, especially busy ones, are tempting targets for cybercriminals looking to intercept sensitive information, including passwords and credit card details.

To protect yourself, you can use a password manager. Password managers create and securely store strong, unique passwords for your applications and accounts. This allows you to access all your passwords with a single master password, which masks your individual passwords.

• Install a password manager: Choose a reputable password manager that works across your devices and browsers, such as Aura's password manager, which works across iOS and Android devices and browsers like Chrome, Firefox, and Microsoft Edge.
• Set up your password manager: Install and configure the password manager on all your devices.
• Enable multi-factor authentication (MFA): If available, enable MFA as part of your password manager's unlocking process. This adds an extra layer of security and helps protect against keylogging malware.
• Use the password manager to create strong, unique passwords: One of the benefits of a password manager is that it can generate complex and unique passwords for your accounts. This is especially useful when accessing sensitive accounts over airport WiFi, as it helps protect your information even if the network is compromised.
• Use the password manager to store your passwords securely: The password manager will mask your individual passwords behind a single master password, making it easier for you to access and manage your passwords without compromising security.
• Only input your credentials on legitimate websites: Most password managers will only input your credentials on legitimate sites, helping to identify fake or spoofed websites that cybercriminals use to steal your information.
• Regularly update your passwords: If you suspect that your device or accounts have been compromised, use a separate secure device to update your passwords.
• Consider additional security measures: For maximum protection, combine the use of a password manager with other security tools such as a virtual private network (VPN), antivirus software, and safe browsing tools.

By following these steps, you can enhance your digital security when using free airport WiFi and reduce the risk of identity theft, account takeovers, and financial losses.

Install antivirus software

Free airport Wi-Fi is convenient, but it may expose you to serious digital security risks. Public Wi-Fi networks are typically untrusted and unsecured, making it easy for hackers to infiltrate your device and steal your personal data.

To protect yourself from cybercriminals when using airport Wi-Fi, it's crucial to have antivirus software installed on your devices. Antivirus software acts as a shield, safeguarding your devices and data from various online dangers. Here are the steps to install antivirus software:
