Apple has patched a critical bug in macOS that could be exploited to take screenshots of someone's computer and capture images of their activity within applications or on video conferences without that person knowing.
Apple addressed the vulnerability-discovered by researchers at enterprise cybersecurity firm Jamf- in the latest version of macOS, Big Sur 11.4, released on Monday, the company told Forbes, according to a published report.
Apple's latest security woe comes on the heels of an Apple exec publicly lamenting the level of malware against the Mac platform, calling it "Unacceptable" in testimony in a California court last Wednesday for a lawsuit brought against the company by Epic Games, maker of Fortnite.
Apple head of software engineering Craig Federighi used the threat level as an excuse for Apple's tight restrictions on the software that is allowed to run on its platform and sell within its iOS App Store.
A week before that, Apple patched a zero-day vulnerability in its MacOS that can bypass critical anti-malware capabilities and which a variant of the notorious Mac threat Shlayer adware dropper already had been exploiting for several months.
The company kicked off the year by removing a contentious macOS feature that allowed some Apple apps to bypass content filters, VPNs and third-party firewalls.
