Hong Kong’s leader Leung Chun-ying and the city’s No 2 official Carrie Lam Cheng Yuet-ngor are among billions who had their mobile phone numbers leaked by smartphone security apps.

The pair were revealed to be victims of leaks by apps CM Security, Truecaller and Sync.ME, which offer users protection against unwanted incoming calls.

The free apps, which can be downloaded for both Android and iOS devices, have been collating users’ phone address books into a publicly available online database, an investigation by Hong Kong-based news agency Factwire has found.
