Dubai: Smart mobile phone users must be careful while connecting to “free” WiFi network at hotels and malls, as hackers can access the devices by making fake WiFi points, Telecommunications Regularity Authority (TRA) warned on Thursday.

An official from the TRA told Gulf News that there are fake open WiFi networks in the city created by hackers to hack data and harm users.

Gaith Al Mazeina, manager of Business Affairs aeCERT at TRA, said that those hackers create fake WiFi with names similar to open WiFi points in the hotels and malls to con the user to log in and hack his device.

“The hackers make the fake WiFi using hotels’ names, for example, by adding a number to the original name and when the user logs in to the network, they can get access and steal the data and control the device. People must be careful when they connect their devices to open WiFi and make sure it contains a username and password,” Al Mazeina told Gulf News.

He claimed that the hackers use the fake WiFi to destroy devices, espionage and blackmail the users. He said that they upload viruses to the device to steal emails, banking accounts and pictures.

Some hackers use ‘ransom ware’ virus to make encryption to the device or the phone and then ask for money before sending the encryption key to the user to recover his device.

“If the user have one per cent suspicion in the open WiFi in the city, then it’s better not to log into it. If you are in a hotel and finds many open WiFi networks, then you must ask the hotel for the original WiFi username. People must protect their personal data and emails with strong passwords,” Al Mazeina said.
