(Bloomberg) -- Singapore halted the use of Zoom Video Communications Inc.’s video-conferencing application for home-based school education following a report of hackers breaching some of the sessions.

“These are very serious incidents,” Aaron Loh, divisional director of educational technology division at the city-state’s ministry of education, said in an emailed reply to Bloomberg News queries. “MOE is currently investigating both breaches and will lodge a police report if warranted,” he said.

The action comes as hackers breached some e-learning modules and displayed obscene images in the sessions, The Straits Times reported on Thursday. Zoom Video is focused on ramping up the security of its application to win back the clients it has lost globally due to privacy concerns, Chief Executive Officer Eric Yuan said in an interview with Bloomberg Television.
