Using free Wi-Fi at airports is convenient but potentially dangerous. Find out which airports are the most risky and learn how to mitigate the risks.
Most airports provide free Wi-Fi for visitors. This is convenient for business travelers who work on their laptops while waiting for their flights.
Taking advantage of this convenience can be risky. The risk level, though, is not the same across all airports, according to a Coronet study. The security researchers came to this conclusion after they gathered and analyzed data from the 45 busiest US airports over a five-month period, starting in January 2018. Part of the research involved scanning Wi-Fi networks (aka hotspots) in the immediate vicinity to determine the likelihood of some of them being run by hackers. The researchers then categorized the Wi-Fi networks by the level of risk (e.g., medium risk, high risk) and calculated the probability of airport visitors connecting to them.
The Four Most Risky Airports
According to the research, the riskiest airports for users of free Wi-Fi are:
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.
