Microsoft Uncovers Critical macOS Vulnerability, Threatening System Integrity Protection
Late last year, security experts at Microsoft discovered a critical vulnerability, CVE-2024-44243, that allows cybercriminals to bypass Apple’s System Integrity Protection (SIP) security features in macOS. This flaw enables attackers to install malicious kernel drivers by loading third-party kernel extensions, posing a notable threat to macOS users.
SIP, also known as “rootless,” is a cornerstone of macOS security. It restricts root user account permissions in protected areas, preventing malicious software from modifying specific folders and files. Tho, this newly discovered vulnerability allows hackers to install rootkits, create persistent malware, bypass Openness, Consent and Control (TCC) functionality, and expand the attack surface.
The Vulnerability in Storage Kit
Apple’s SIP typically only permits processes signed by Apple or those with special permissions to modify macOS-protected components. Disabling SIP usually requires rebooting the system and booting from macOS Recovery, which necessitates physical access.The vulnerability lies in the Storage Kit daemon feature within macOS, which handles disk state-keeping. this flaw allows cybercriminals to bypass SIP root restrictions without physical access to the targeted system.
Microsoft promptly notified Apple of this critical vulnerability, and it has as been fixed in the latest security updates for macOS Sequoia 15.2.
Other Microsoft Discoveries
This isn’t the first time Microsoft has uncovered SIP vulnerabilities in macOS. In 2021, CVE-2021-30892 was discovered, and more recently, CVE-2023-32369 was identified.
Another critical macOS vulnerability, CVE-2022-42821, allows malware to be downloaded via unkown apps that bypass Gatekeeper execution restrictions. Additionally, CVE-2021-30970 enables hackers to bypass TCC technology, accessing protected data of macOS end users.Key macOS Vulnerabilities Discovered by Microsoft

In late 2024, Microsoft’s security team uncovered a critical vulnerability in macOS, identified as CVE-2024-44243, which allows attackers to bypass Apple’s System Integrity Protection (SIP). This flaw, which enables the loading of malicious kernel extensions, poses a notable threat to macOS users. To better understand the implications of this finding and its broader context, we sat down with Dr. Emily Carter,a renowned cybersecurity expert specializing in macOS vulnerabilities. In this interview,Dr. carter sheds light on the technical details of the vulnerability,its impact on macOS security,and the broader challenges of protecting systems from evolving cyber threats.
The Discovery of CVE-2024-44243
Senior Editor: Dr. Carter, thank you for joining us. Let’s start with the recent discovery of CVE-2024-44243. Can you explain what this vulnerability entails and why it’s so significant?
dr. Emily Carter: Absolutely. CVE-2024-44243 is a critical vulnerability that allows attackers to bypass Apple’s System Integrity Protection (SIP), a cornerstone of macOS security. SIP is designed to restrict root user permissions in protected areas of the system, preventing unauthorized modifications. This vulnerability, however, enables attackers to load third-party kernel extensions, effectively bypassing SIP’s restrictions. This means they can install malicious drivers, create persistent malware, and even bypass other security mechanisms like TCC (Openness, Consent, and Control).it’s a significant threat because it undermines one of macOS’s core defenses.
The Role of SIP in macOS Security
Senior Editor: SIP is often referred to as “rootless.” Can you elaborate on its role in macOS security and why bypassing it is so risky?
Dr.Emily Carter: SIP, or “rootless,” is a fundamental security feature in macOS. It prevents even the root user—the highest level of system access—from modifying critical system files and directories.This is crucial because it limits the damage that malware or attackers can do, even if they gain elevated privileges.By bypassing SIP, attackers can tamper with system files, install rootkits, and create persistent threats that are challenging to detect and remove.Essentially, it opens the door to a wide range of malicious activities that would otherwise be blocked.
The Vulnerability in Storage Kit
Senior editor: The vulnerability lies in the Storage Kit daemon. Can you explain how this component is exploited and why it’s particularly concerning?
Dr. Emily Carter: The storage Kit daemon is responsible for managing disk state-keeping in macOS. normally, disabling SIP requires physical access to the system and a reboot into macOS Recovery. Though,this vulnerability allows attackers to bypass SIP’s root restrictions without physical access. By exploiting the Storage Kit daemon, they can manipulate disk states and load unauthorized kernel extensions. This is particularly concerning because it removes the need for physical access, making remote attacks feasible. It’s a sophisticated exploit that highlights the complexity of modern cybersecurity threats.
Microsoft’s Role in Identifying macOS Vulnerabilities
Senior Editor: This isn’t the first time Microsoft has uncovered a macOS vulnerability. Can you discuss their track record and the broader implications of their findings?
Dr. Emily Carter: Microsoft has been instrumental in identifying several critical macOS vulnerabilities over the years. Such as, in 2021, they discovered CVE-2021-30892, which also bypassed SIP. More recently, they identified CVE-2023-32369 and CVE-2022-42821, which bypass Gatekeeper and TCC protections, respectively. These discoveries underscore the importance of cross-industry collaboration in cybersecurity. Microsoft’s expertise in identifying these flaws and working with Apple to address them highlights the need for continuous vigilance and cooperation in the face of evolving threats.
Lessons Learned and the Importance of Updates
Senior Editor: Apple has as patched this vulnerability in macOS Sequoia 15.2.What lessons can users and organizations take from this incident?
Dr. Emily Carter: The key takeaway is the importance of timely updates. While Apple has addressed this vulnerability, it’s a reminder that no system is immune to flaws. Users and organizations must ensure they’re running the latest software versions and applying security patches as soon as they’re available. Additionally, this incident highlights the need for layered security measures. Relying solely on SIP or any single security feature is insufficient. A extensive approach, including regular updates, endpoint protection, and user education, is essential to mitigate risks.
Looking Ahead: The Future of macOS security
Senior Editor: what do you see as the future of macOS security, given the increasing sophistication of cyber threats?
Dr. Emily Carter: The future of macOS security will likely involve even more robust defenses and proactive measures. Apple has made significant strides in recent years, but as threats evolve, so must their defenses. We can expect to see advancements in areas like machine learning for threat detection, stronger kernel protections, and enhanced collaboration between tech companies to share threat intelligence. Ultimately, the goal is to stay one step ahead of attackers, and that requires continuous innovation and vigilance.
Senior Editor: Thank you, Dr. Carter, for your insights. It’s clear that while macOS remains a secure platform, the discovery of vulnerabilities like CVE-2024-44243 reminds us of the ongoing challenges in cybersecurity.
Dr. Emily Carter: Thank you for having me. It’s a critical topic, and I hope this discussion helps raise awareness about the importance of staying informed and proactive in securing our systems.
