What You'll Learn
Airports are a hunting ground for cybercriminals
Airports have become a hunting ground for cybercriminals due to the large number of connected devices and systems, from security cameras to baggage handling systems, each of which can be a potential target. Airports handle sensitive data, including passenger information, airline schedules, and cargo manifests, making them prime targets for cyber-attacks. Their reliance on complex industrial control systems further increases their vulnerability to disruptive cyber-attacks, which can result in flight disruptions, data breaches, financial losses, and harm to their reputation and customer trust.
The interconnectedness of airport systems means that a single breach can quickly spread across the entire airport infrastructure. Cybercriminals can exploit vulnerabilities in airport systems through various methods, including phishing, malware, ransomware, and denial-of-service (DoS) attacks. Airports, therefore, need to prioritise cybersecurity and implement robust security measures to safeguard their assets and sensitive data.
Additionally, airport customers and employees are also at risk of cyberattacks when using public Wi-Fi networks. Airports often provide free and unlimited Wi-Fi, which can be a tempting target for sophisticated cybercriminals looking to intercept sensitive information. Attackers can set up fraudulent Wi-Fi hotspots that resemble legitimate airport networks, tricking devices into automatically connecting and exposing user data. Malicious pop-ups and packet sniffing attacks are also common tactics used by cybercriminals to steal personal information and passwords.
To protect themselves, individuals should disable the automatic connection to Wi-Fi networks and confirm the legitimate network name with airport customer service. Using a virtual private network (VPN) can also boost security by encrypting data. Airports can enhance cybersecurity by partnering with ISO 27001-certified suppliers, implementing internationally recognised standards for information security management systems, and prioritising regulatory compliance related to cybersecurity.

Airports may outsource WiFi responsibility, compromising security
Airports are a haven for cybercriminals looking to exploit unsuspecting travellers who connect to unsecured public Wi-Fi networks. Airports often outsource the responsibility for providing Wi-Fi to third-party companies, which can compromise security further.
At Dallas Love Field Airport, for instance, the Wi-Fi provider is Boingo, a company that provides services to approximately 60 airports in North America. While Boingo has offered Passpoint since 2012 to enhance Wi-Fi security, the airport's IT team does not have access to their systems or usage dashboards. This lack of visibility into the Wi-Fi infrastructure can make it challenging for airports to identify and mitigate potential security risks.
Outsourcing Wi-Fi services to external providers can create a disconnect between the airport's IT systems and the Wi-Fi network, as in the case of Dallas Love Field Airport. This separation may be intentional to protect the airport's internal networks from potential breaches. However, it also means that the airport's IT team may have limited ability to monitor and secure the Wi-Fi network directly.
Additionally, cybercriminals often target airport Wi-Fi connections using tactics such as fraudulent Wi-Fi hotspots, malicious pop-ups, and packet sniffing attacks. They may set up look-alike networks disguised as the airport's legitimate public network, tricking travellers' devices into automatically connecting to unsecured connections. Airports that outsource Wi-Fi responsibility may not have the necessary tools or expertise to detect and prevent such attacks, leaving travellers vulnerable to data breaches and identity theft.
To protect themselves, travellers should be cautious when using airport Wi-Fi and avoid automatically connecting to networks that appear legitimate. Utilizing a virtual private network (VPN) can also boost security by encrypting data and preventing easy observation of network traffic. Being vigilant and employing these security measures can help mitigate the risks associated with airport Wi-Fi, even when the responsibility for Wi-Fi is outsourced by the airport.

Public WiFi networks can be mimicked by hackers
Public Wi-Fi networks are convenient, but they also pose serious risks to users' digital safety. Airports, in particular, are a hotspot for cybercriminals due to the high volume of travellers passing through and connecting to the airport's Wi-Fi. This makes airports an ideal hunting ground for hackers looking to intercept sensitive information. In fact, one out of every four travellers has been hacked over public Wi-Fi networks while abroad, with many of these attacks occurring at major airports.
Hackers have various methods to mimic public Wi-Fi networks and gain access to users' personal information. One common method is the "evil twin" attack, where hackers set up malicious hotspots with seemingly legitimate and trustworthy names. For example, a network named "Airport Free Wi-Fi" may be a malicious hotspot set up by a hacker. When users connect to these networks, their data can be easily intercepted. Additionally, hackers can insert themselves between users and unsecured public Wi-Fi networks, capturing data in transit.
Another tactic employed by hackers is to take advantage of devices that automatically connect to public Wi-Fi hotspots. Many smartphones and computers are set up to automatically join available Wi-Fi networks, and this feature can be exploited by hackers. By setting up a fraudulent Wi-Fi hotspot, hackers can gain access to users' devices and data without their knowledge. It is important for users to disable automatic connections to public Wi-Fi networks, especially in busy airport environments.
To protect against these threats, it is recommended to use a virtual private network (VPN) when connecting to any public Wi-Fi hotspot. A VPN boosts security by creating an encrypted connection between your device and a server, making it more difficult for hackers to intercept your data. Strong encryption is crucial in safeguarding personal data over public Wi-Fi. Additionally, users should be cautious when joining public Wi-Fi networks and should verify the legitimacy of the network with airport customer service before connecting.
By being aware of the risks associated with public Wi-Fi networks and taking the necessary precautions, such as using a VPN and disabling automatic connections, travellers can significantly reduce the chances of becoming victims of cyberattacks when using airport Wi-Fi or any other public Wi-Fi network.

Personal information is often exchanged for WiFi access
Many airports offer free WiFi in exchange for personal information. However, this poses a serious risk to digital safety and makes travellers vulnerable to cybercriminals. Airports are ideal hunting grounds for hackers due to the sheer number of people passing through, often with the intention to connect to the internet.
When connecting to a website, sensitive data such as login information, financial details, and email or social media account information can be exposed. This data can be intercepted by attackers who insert themselves between users and unsecured public WiFi networks. In some cases, hackers create fraudulent WiFi hotspots that automatically connect through devices looking for public WiFi. They can also insert malicious pop-ups into legitimate airport web pages, which, when clicked on, download malware or direct users to fake websites that steal personal information.
To avoid these risks, it is recommended to use a Virtual Private Network (VPN) when connecting to public WiFi. A VPN boosts security by creating an encoded tunnel between a device and a server, making it harder for cybercriminals to observe network traffic. Other ways to protect personal information when using public WiFi include keeping operating systems, browsers, and security software up to date, using strong passwords, and turning on two-factor authentication.
While WiFi in exchange for personal information may be convenient, it is important for travellers to be aware of the potential risks and take the necessary precautions to protect their data.

Airports may require local SIM cards or phone numbers for WiFi access
Many airports around the world provide free, unlimited WiFi to passengers. However, some airports, particularly those in India, require passengers to have local SIM cards or phone numbers to access WiFi. This restriction is in place for security reasons, as there is no mandatory KYC (know your customer) check for international mobile phone connections.
At Bangalore Airport, for example, passengers must scan their passports and boarding passes to receive WiFi vouchers. Delhi Airport also provides WiFi vouchers, which can be obtained from kiosks located throughout the airport. Kolkata Airport requires passengers to provide a local phone number to access the WiFi.
Some international passengers may find it inconvenient to obtain a local SIM card or phone number, especially during a short layover. In such cases, it may be necessary to purchase roaming services from a telecom provider or use an alternative method of internet access, such as a mobile hotspot.
To avoid the hassle of obtaining a local SIM card or phone number, some travellers use eSIM apps, which can be installed in advance and activated upon arrival. These apps may not offer the best deals, but they can be very practical for travellers who need temporary internet access.
