With the enterprise adoption of MacOS and iOS devices increasing, the Apple security landscape is becoming increasingly complex.

With iOS 16 and macOS Ventura, Apple is introducing passkeys—a more convenient and secure alternative to passwords.

One of the things Apple cares about in terms of its bug bounty program is your location data. Apple rightly categorizes real-time or historical precise location data as "sensitive data" which in some cases qualifies for a significant monetary award.

Here are two proof-of-concepts for CVE-2022-26766 (CoreTrust allows any root certificate) and CVE-2022-26763 (IOPCIDevice::_MemoryAccess not checking bounds at all), two issues discovered by @LinusHenze and patched in macOS 12.4 / iOS 15.5.

New domains and new behavioral indicators, but malware authors stick to tried and tested architecture despite Apple’s updates.

Zoom has issued a patch for a bug on macOS that could allow a hacker to take control of a user’s operating system (via MacRumors). In an update on its security bulletin, Zoom acknowledges the issue (CVE-2022-28756) and says a fix is included in version 5.11.5 of the app on Mac, which you can (and should) download now.

In macOS 12.0.1 Monterey, Apple fixed CVE-2021-30873. This was a process injection vulnerability affecting (essentially) all macOS AppKit-based applications. We reported this vulnerability to Apple, along with methods to use this vulnerability to escape the sandbox, elevate privileges to root and bypass the filesystem restrictions of SIP.

With a recent market cap of over $100 billion and the genericization of its name, the popularity of Zoom is undeniable. But what about its security? This imperative question is often quite personal, as who amongst us isn't jumping on weekly (daily?) Zoom calls?

In this talk, we’ll explore Zoom’s macOS application to uncover several critical security flaws. Flaws, that provided a local unprivileged attacker a direct and reliable path to root.

The first flaw, presents itself subtly in a core cryptographic validation routine, while the second is due to a nuanced trust issue between Zoom’s client and its privileged helper component.

After detailing both root cause analysis and full exploitation of these flaws, we’ll end the talk by showing how such issues could be avoided …both by Zoom, but also in other macOS applications.

If you’re still running macOS Mojave or earlier, now is the time to take action to ensure your Mac maintains protection against malware.
