Apple has released the macOS Big Sur 11.2 release candidate for developers. This follows the other final beta versions of its other operating systems.
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.
Like the iOS 14.4 developer beta, macOS betas can be downloaded from Apple’s developer page. Release notes haven’t been published.
File encryption app Boxcryptor has been updated to support macOS Big Sur and M1 Macs to keep your documents safe in the cloud.
