MacOS 10.13 Authentication Bypass

Speak With A Security Expert Now

An authentication flaw has been discovered in MacOS version 10.13 (High Sierra) and MacOS 10.13.2 beta. A threat actor with remote or physical access to the device can gain administrative privileges by logging in with the user account "root" through System Preferences. Remote attacks require Apple's Remote Desktop Protocol. No password is required and once completed the threat actor will have persistent access to the device.

This is a trivial attack to perform and has a wide range of potential consequences namely, unauthorized access.
