Using free WiFi at airports is convenient but potentially dangerous. According to a recent Coronet study, these four airports are the riskiest:
1. San Diego International Airport in California.
There is a 30% chance of connecting to a medium-risk network and a 11% chance of connecting to high-risk hotspot at this airport. The researchers even found an “evil twin” Wi-Fi access point with the name “#SANfreewifi”, which was being used for Address Resolution Protocol (ARP) poisoning attacks. With this type of attack, cybercriminals can eavesdrop on the data being sent over the Wi-Fi network, steal sensitive data, and carry out other malicious activities.
2. John Wayne Airport-Orange County Airport in California.
At this facility, the probability of connecting to a medium-risk hotspot is 26%, while the probability of connecting to high-risk one is 7%.
3. Houston William Hobby International Airport in Texas.
When the researchers were scanning the Wi-Fi networks at this airport, they found a cybercriminal using a Wi-Fi hotspot named “SouthwestWiFi” to perform on attacks on SSL/HTTPS traffic. This is one reason why there is a 21% chance of connecting to a medium-risk network at this facility and a 6% chance of connecting to high-risk one.
4. Southwest Florida International Airport.
At this location, the probability of connecting to a medium-risk hotspot is 19%, while the probability of connecting to high-risk one is 6%.
These percentages might not seem too bad until you compare them to the national level. When looking at all 45 airports as a whole, there is only a 1% chance of connecting to a medium-risk network and a 0.6% chance of connecting to high-risk hotspot. So, if you are visiting one of these four airports, you should be more vigilant about security if you plan to use free Wi-Fi there.
