The southeast Asian country’s Ministry of Education said teachers will “progressively” resume use of the videoconferencing service with extra security measures in place for at-home lessons amid a coronavirus lockdown, according to local news reports.

The ministry has reportedly filed police reports about two breaches from last week. One parent reported that her daughter’s geography lesson was interrupted by obscene images and two men who asked girls to expose themselves.

Education officials worked with Zoom to create a single button that makes it easier for teachers to activate the platform’s security features, reports say. The ministry is also reportedly managing default settings for teachers and disabling the screen-sharing and annotation features.

“As security concerns are addressed and users become more familiar with the security protocols, we will progressively enable these features again,” Aaron Loh of the ministry’s educational technology division told Singapore’s Straits Times newspaper Monday.

American school systems including New York City’s have stopped using Zoom over concerns about miscreants crashing classes. Security worries have also led big companies such as Tesla and Google to discourage employees from using the service.

Zoom has said it was “deeply upset” by incidents like those reported in Singapore and that it has tweaked settings for education users to make sessions more secure.

Zoom’s stock price was up about 3.9 percent in premarket trading at $141.20 as of 8:54 a.m. Tuesday following a 9.1 percent jump Monday.
