Wi-fi is still down at the world's busiest airport, four days after Hartsfield-Jackson International officials took down the wireless Internet access due to a cyber attack on Atlanta city government.
Some tools on the airport's website are also still down, such as security wait times and flight information. "While we aren't directly affected by the cyberattack, we are being abundantly cautious and have taken these systems offline," Atlanta airport spokesman Reese McCranie said.
There are risks in using public wi-fi at an airport, according to Michael Nowatkowski, associate professor of information security at Augusta University. He recommends avoiding online banking or online shopping when on public wi-fi. The vulnerabilities at an airport are similar to any public wi-fi, he said. “What makes it maybe more of a danger at an airport is simply the concentration of the number of people in that area, so that would just expose you to more potential hazards, more people that might want to take advantage of your system,” Nowatkowski said.
