Apple Apps No Longer Bypass macOS Big Sur Firewalls

Andrew Orr · · Add Comment

In macOS Big Sur, Apple deprecated third-party kernel extensions including Network Kernel Extensions (NKEs). NKEs are used by apps like firewalls to monitor network traffic. Apple’s new user-mode Network Extension Framework had a side-effect: Apple’s own apps wouldn’t be routed through it and thus could bypass third-party firewalls. But now that has changed.

I of course also wondered if malware could abuse these “excluded” items to generate network traffic that could surreptitiously bypass any socket filter firewall.  Unfortunately the answer was yes! It was (unsurprisingly) trivial to find a way to abuse these items, and generate undetected network traffic.

First Developer Beta for macOS 11.1 Out Now

Charlotte Henry · · Add Comment

Apple has released the first developer beta of macOS Big Sur 11.1, AppleInsider reported. Those enrolled in the test program can download it via the Apple Developer Center. There is an over-the-air update for devices already running beta software.

The beta is the first since Apple released macOS Big Sur to the public on November 12, in the form of macOS 11.0.1. More than ten beta builds were released in the time between Big Sur’s announcement and its eventual release, and roughly two months after Apple issued public versions of other operating systems including iOS 14. It is so far too early to determine what Apple has changed in the first beta, but it is likely to include some trial fixes for a range of launch issues.
