Vulnerability dubbed Shrootless (now tracked as CVE-2021-30892) was discovered by Microsoft’s Microsoft 365 Defender Research Team. System Integrity Protection (SIP) is a macOS security technology that blocks potentially malicious software from modifying protected folders and files. SIP only allows processes signed by Apple or those with special entitlements (i.e., Apple software updates and Apple installers) to modify protected parts of the OS. Apple issued a fix to address the security flaw with the security updates released two days ago.”]
