Mac security hole reportedly lets attackers bypass app safeguards

Apple may have another Gatekeeper security flaw on its hands. Researcher Filippo Cavallarin has detailed a macOS vulnerability that he said would let attackers install malware without the usual permission request. As Gatekeeper considers network shares to be 'safe' locations that don't require permission checks, an intruder just has to trick the user into mounting one of those shares to run the apps they like. A maliciously crafted ZIP file with the right symbolic link could automatically steer you to an attacker-owned site, for example, and it would be easy to trick someone into launching a hostile app -- say, a virus masquerading as a document folder.
