A bug levers the System Integrity Protection security function. Apple already distributes patches to Macos Monterey, Big Sur and Catalina.

Microsoft security researchers have discovered a very critical vulnerability in Apple's desktop operating system MacOS . It is in a security feature called System Integrity Protection. An attacker may possibly insert a harmful kernel driver for unpacked systems and set up a root kit. A patch of Apple is already available.

According to Microsoft, a harmful kernel driver can provide a hardware interface that allows you to "overwrite system files or permanently install a non-trackable malware". The discovery of the bug shows that Microsoft is increasingly focusing on enterprise customers using a mix of Windows and MacOS.

"This security vulnerability on the operating system level and others who are inevitably revealed increase the number of possible attack vectors that can exploit attackers", explained Jonathan Bar OR from the Microsoft 365 Defender Research Team. "Since networks are becoming more and more heterogeneous, the number of threats to try to compromise non-Windows devices."

System Integrity Protection actually scents MacOS with the help of Apple's Sandbox to users with root rights. The error found by Microsoft occurred in connection with system updates that require unrestricted access to protected directories. Apple has introduced a specific group of permissions that purposely deal with system integrity protection tests.

"Over the years, Apple SIP hardened with improved restrictions against attacks", supplemented Or. "One of the most notable SIP restrictions is the limitation of the file system. This is especially important for red teamers and malicious actors, as the damage you can do on the critical components of a device, directly depends on your ability to write unlimited data to the hard disk. "

The vulnerability in question with the CV-2021-30892 identifier has been eliminated by Apple with MacOS Monterey 12.01. Security updates are also available for the previous versions Catalina and Big Sur.

Joe Hartman, deputy commanding general of U.S. Cyber Command, told ABC News' Chief Justice Correspondent Pierre Thomas. "On a daily basis, whether it's nation-state, malicious cyber actors trying to steal secrets, whether it's ransomware actors -- every day our adversary gets up and attempts to execute operations against the United States. They're not going to stop and neither are we.
