A cybersecurity report reveals several fake WiFi hotspots have been set up in Rio de Janeiro, Brazil, in order to take advantage of the influx of people attending the 2016 Olympics.
Skycure, a mobile security firm, found that places like Rio Galeão Airport are unaware they were inadvertently hosting several nefarious networks, according to Forbes. In other words, tourists arriving in the city are leaving themselves vulnerable to hackers once they turn on their phones or turn off airplane mode.
Another report, published by Kaspersky Lab, discovered that 18 percent of the available networks were highly unsafe. Another 7 percent used antiquated encryption technology.
Mobile phone users have to attempt to connect to a fake WiFi network to have their personal data compromised, but hacker criminals will often create networks with names extremely similar to legitimate ones.
Forbes created a comprehensive map of all of the all of the areas with the best cell phone service.
The 2014 Olympics in Sochi, Russia, had a similar problem, in which all visitors were reported to be hacked once arriving.
