What You'll Learn
Identity theft and account takeovers
Airport Wi-Fi is a tempting target for cybercriminals due to the high volume of users and the ease of access. This makes it relatively easy for hackers to exploit network vulnerabilities and engage in identity theft and account takeovers.
Identity theft occurs when hackers intercept data transmitted over a compromised network. This can include passwords, Social Security numbers, bank account numbers, credit card information, and other personal data. With this information, cybercriminals can steal identities, break into online accounts, and incur financial losses.
Account takeovers happen when scammers gain unauthorized access to email, bank, or social media accounts. They may lock out the legitimate user and misuse their information. This can occur when individuals access these accounts over public Wi-Fi, as hackers can spy on their activity and steal login credentials.
To protect against identity theft and account takeovers while using airport Wi-Fi, individuals should be cautious about connecting to networks and avoid sending sensitive information. It is recommended to use mobile data or a Virtual Private Network (VPN) for added security. Keeping security updates current and being vigilant against malicious pop-ups and fake login pages can also help prevent identity theft and account takeovers.

Fake Wi-Fi networks
Airport Wi-Fi networks are far less secure than your home network and should be used sparingly and with caution. Airports are a tempting target for sophisticated cybercriminals looking to intercept sensitive information, including login credentials, credit card details, and account passwords.
One common scam is the "evil twin" attack, where hackers create fake Wi-Fi networks with names that look similar to the airport's legitimate free network. These fraudulent networks can trick unsuspecting users into entering their personal details, which can then be used to steal their identities or break into their online accounts. This type of attack is especially dangerous because it is difficult to distinguish a legitimate network from a fake one, and it only takes a basic level of IT skills to carry out.
In addition to "evil twin" attacks, cybercriminals may also set up fake login pages that demand personal data or credit card information from travelers. These pages may appear when users try to connect to the airport's Wi-Fi network, and if they enter their information, it is then saved to the hacker's devices. Another tactic is to insert malicious pop-ups into legitimate airport web pages and services, prompting users to sign up for "advanced free features" or install software that could contain malware.
To protect yourself from fake Wi-Fi networks and other scams, it is recommended to use a Virtual Private Network (VPN) when connecting to public Wi-Fi. A VPN encrypts your data and shields you from cyber eavesdroppers. You should also avoid using public Wi-Fi for sending personal or financial information and turn off file and printer sharing to prevent unauthorized access to your personal files. Keeping your security updates up-to-date and exercising caution when entering your information can also help prevent data theft.

Malware infections
Airport Wi-Fi networks are far less secure than your home network and should be used with caution. Airports are a tempting target for cybercriminals looking to intercept sensitive information, and one out of every four travelers has been hacked over public Wi-Fi networks while abroad.
One way that hackers target airport Wi-Fi users is by creating fake Wi-Fi networks that look similar to the airport's legitimate free network. If you connect to these networks, scammers can intercept any unencrypted data sent over the network, including login credentials.
Another way that hackers can gain access to your data is through malicious pop-ups. Attackers may insert pop-ups into legitimate airport web pages and services. If you click on them, you may download malware onto your device or enter a fake website that steals your personal information.
To protect yourself from malware infections when using airport Wi-Fi, there are several precautions you can take:
- Avoid using public Wi-Fi for sending personal or sensitive information. If you need to access this type of information, use your cellular data as a mobile hotspot instead.
- Disable file and printer sharing on your device to prevent unauthorized persons from accessing your files.
- Be wary of suspicious pop-ups or prompts asking you to sign up for "advanced free features," install a browser extension, or download software. Do not click on these unless you are sure they are from a safe source.
- Use a Virtual Private Network (VPN) to encrypt your internet traffic and shield your data from cyber eavesdroppers. Choose a reputable VPN provider and avoid free VPNs, as they may log your data.
- Install reputable antivirus software on your device to detect and block malware in real-time. Ensure that your antivirus software is enabled, properly configured, and up-to-date before traveling.

Data harvesting
Airport Wi-Fi networks are a prime target for cybercriminals looking to steal information, identities, and money. Airports are particularly vulnerable because they are often unsecured or poorly encrypted, making it easy for hackers to intercept data, steal sensitive information, or even install malware on unsuspecting travellers' devices.
One common method of attack is the "man-in-the-middle" (MitM) attack, where a hacker intercepts your internet connection and positions themselves between you and the legitimate network. This allows them to read, modify, and even inject malicious data into your connection without your knowledge. Many public Wi-Fi networks don't use WPA2 encryption, making it easier for hackers to eavesdrop on your activity.
Another tactic used by cybercriminals is to set up fake Wi-Fi networks with names that look similar to the airport's legitimate free network, such as "Airport_Free_WiFi". These networks may ask for personal information, such as your birthday or email credentials, or even your credit card information. Real airport networks will never ask for this type of information. Even on legitimate networks, skilled attackers can monitor unencrypted web traffic and collect personal data.
To protect yourself from data harvesting when using airport Wi-Fi, it is recommended to use a Virtual Private Network (VPN) to encrypt your connection and prevent hackers from spying on your data. Verify the network name with an airport employee before connecting, and avoid logging into sensitive accounts or providing personal information. It is also a good idea to disable auto-connect on your device to prevent it from automatically connecting to unsecured networks.
