Singapore stops Zoom for online education as hackers strike

HONG KONG: Singapore has suspended the use of Zoom for online education after hackers hijacked a lesson and showed obscene images to students.

In what is known as Zoombombing, two hackers interrupted a geography lesson a day after Singapore closed schools on Wednesday in partial lockdown measures to help curb local transmissions of the coronavirus. Lessons have moved online, with some teachers using video conferencing tools like Zoom.

Singapore’s Ministry of Education said it was investigating the serious incidents and may file police reports.

We are already working with Zoom to enhance its security settings and make these security measures clear and easy to follow, said Aaron Loh, director of the ministry’s Educational Technology Division.

As a precautionary measure, our teachers will suspend their use of Zoom until these security issues are ironed out,” Loh said.

Singapore is not the only country to be affected by the teleconferencing disruptions. The FBI issued a warning on March 30 advising users to avoid making Zoom meetings public after it received multiple reports of teleconferences and online classrooms being disrupted by hackers displaying hate messages or shouting profanities.

Part of the Zoombombing problem occurs because users tend to create public meetings out of convenience. That allows anyone to join a meeting as long as they have a link for it, according to Michael Gazeley, managing director and co-founder of cybersecurity firm Network Box.

Details of conferences are often given out in a public manner, because organisers want as many attendees as possible, said Gazeley.
