Zoom, the video-conferencing app that has seen a huge rise in downloads since quarantines were imposed around the world, is now being used by millions for work and social gatherings.
This week Prime Minister Boris Johnson tweeted a picture of himself chairing a Cabinet meeting via the app. This led to questions about how secure it was for government meetings.
Zoom has angrily defended its security record, saying it would answer any questions the government had.
“Globally, 2,000 institutions ranging from the world’s largest financial services companies to leading telecommunications providers, government agencies, universities, healthcare and telemedicine practices have done exhaustive security reviews of our user, network and data centre layers confidently selecting Zoom for complete deployment.”
“We are in close communication with the UK Ministry of Defence and National Cyber Security Centre and are focused on providing the documentation they need,” it said in a statement to the BBC.
Zoom has had security flaws in the past, including a vulnerability which allowed an attacker to remove attendees from meetings, spoof messages from users and hijack shared screens. Another saw Mac users forced into calls without their knowledge. All these were patched but some experts still think that the firm has a rather blase attitude to security.
Zoom started in 2011 by Chinese software engineer Eric Yuan, who emigrated from China to Silicon Valley at the age of 27, Zoom has quietly overtaken rivals such as Skype and Microsoft Teams, in part because of some pretty simple features including adaptive backgrounds.
