Two billion numbers, including those of Hong Kong officials, leaked by Chinese phone app
Among those affected are security minister Lai Tung-kwok and privacy commissioner Stephen Wong, according to news agency FactWire
A Chinese smartphone application which filters unwanted phone calls has been found to be secretly uploading personal data of users – including those of the city’s officials – to a public directory.
The app, DU Caller, developed by DU Group, a subsidiary of Baidu, was initially for users to blacklist nuisance callers and filter them out.
But a “reverse look-up” function allowed access to two billion phone numbers stored in Baidu’s Beijing server, including that of Secretary for Security Lai Tung-kwok, police chief Stephen Lo Wai-chung and officials from the central government’s liaison office.
The Security Bureau has referred the case to the Office of the Privacy Commissioner for Personal Data for investigation.
Independent news agency FactWire reported on Saturday that once downloaded and installed, the app would automatically gather sensitive information such as the address book and phone numbers even before users agreed to the privacy policy.
The app has been downloaded between one and five million times on the Google Play store. It is not yet available for iPhone users in Hong Kong.
