Singapore stops using Zoom for online education as hackers strike

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

Part of the Zoombombing problem occurs because users tend to create public meetings out of convenience, which allows anyone to join a meeting as long as they have the link, 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, Gazeley said.
With Zoom, it was possible to set up meetings without passwords, so of course many people did just that. Whenever humans are given a choice between convenience and security, convenience almost always wins.
Following the increase in hacking incidents, Zoom implemented stronger security measures last week, such as enabling passwords and virtual waiting rooms for users.

We have been deeply upset by increasing reports of harassment on our platform and strongly condemn such behaviour, a Zoom company spokesperson said. “We are listening to our community of users to help us evolve our approach and help our users guard against these attacks.”

Security researchers previously found software vulnerabilities in Zoom, in particular for Mac users where hackers could take over a user’s webcam feed. Zoom has since fixed the issue.
