This new threat is real. Microsoft warns it has likely been exploited, giving attackers “unauthorized access to a user’s protected data.” And that data includes “browsed webpages, the device’s camera, microphone, and location,” all without you knowing.,” affects macOS users where their devices have centralized control via a mobile device management setup. As such, this is a risk to enterprise users rather than home users.
“We encourage macOS users to apply these security updates as soon as possible,” Microsoft says. TCC is designed to protect your private data from apps running on your machine, “including services such as location services, camera, microphone, downloads directory, and others, without prior consent and knowledge.” When an app does require access, you should see a pop-up asking for the specific permission.
‘This Needs To Stop’—Tesla Billionaire Elon Musk Issues ‘Staggering’ Fed ‘Bankruptcy’ Warning After Sparking Bitcoin Price PanicThe issue, as Microsoft explains, is that “Apple reserves some entitlements to their own applications, which are known as private entitlements… Safari, the default browser in macOS, has very powerful TCC entitlements.” Those entitlements include access to your camera, microphone, screen as well as a raft of personal data.
Microsoft explains that Safari’s access to these sensitive device functions “completely bypasses TCC access checks for those services,” and warns that “in a real scenario, an attacker could do stealthy things, including: “save an entire camera stream, record microphone and stream it to another server or upload it, get access to the device’s location,’ start Safari in a very small window to not draw attention.
Apple has now hardened Safari to prevent modification of those configurations files. And Microsoft says it is now “collaborating with other major browser vendors to investigate the benefits of hardening local configuration files. While Chromium and Firefox is yet to adopt the new APIs, Chromium is moving towards using os_crypt which solves the attack in a different way.”Our community is about connecting people through open and thoughtful conversations.
