(ECNS) -- Some mobile apps that help people squat on WiFi connections may involve violations such as revealing other people's personal data, the Ministry of Industry and Information Technology said.
Mobile apps "Wifi Master Key" and "Wifi Key" can provide smartphone users free WiFi connections by linking to the networks of other users, according to media reports. These connections were suspected of intruding on people's personal networks and filching user information.
In a statement on April 3, the ministry said it was paying close attention to the reports and was conducting a technological analysis of the two apps. It was requiring communication authorities in Shanghai and Fujian Province to investigate and deal with the case in accordance with the law.
The ministry also warned smartphone users to pay attention to the security of their WiFi networks. Mobile internet users should also regularly update the password for their WiFi connections and share their WiFi information carefully.
