![]() ![]() It would be like your doctor only having knowledge and incentive to inquire about the human diseases and maladies that she has dealt with over her career. If Microsoft’s security researchers only focused on security issues within Microsoft’s products they would have a very narrow understanding and limited knowledge of security in general. Security issues have no boundaries and security researchers need to root them out wherever they may be hiding, which includes other people’s products, other people’s designs, and other people’s code. But human health and the diseases involved, just like security “diseases,” are global concerns and those who seek to identify cures and limit the occurrence of such diseases should not limit the scope of their research and knowledge acquisition to only include concerns that affect the financial results of their employer. ![]() Their work and feedback goes a long way towards helping product designers across the board and regardless of product or company affiliation avoid security vulnerabilities in the first place. Security researchers are often the ones who have researched and identified the root causes in logic, design, and implementation that led to the security flaws that manifest themselves as vulnerabilities in any product. I’m not picking on you or any of the other homers questioning why Microsoft would seemingly be “debugging” Apple software, but there is a fundamental difference between security researchers and scientists who are deeply embedded in cybersecurity as a discipline and practice versus security focused product development and quality engineers who are tasked with identifying and eradicating security issues in their company’s products. They are so busy swatting their sheit, when do they have the time to debug others? Microsoft (of DOS & Windows infamy) that has more bugs and malware than there are pebbles on the beach. If you want to remain protected against this vulnerability, update your Mac to the latest version.Īpple released macOS Ventura 13.4 on May 18, 2023, which primarily included security patches and other improvements. As a result, Apple was able to patch the potential attack point with a software update released in May. Instead, they were able to run the exploit via Setup Assistant using a specially crafted Time Machine backup file with AppleScript's help.Īs mentioned above, Microsoft already notified Apple of this particular vulnerability. The Microsoft engineers discovered that simply patching Migration Assistant would not be sufficient to stop the exploit. ![]() An attack like this is easy for someone who has hands-on the computer, but Migraine is exploitable even when that isn't the case. One of the reasons this exploit was so dangerous, is the ability for attackers to do so remotely. Microsoft outlines how SIP, and entitlements, work in macOS, and goes into detail how they discovered "Migraine," the approach of the exploitation, and general implications of attacks that are possible by bypassing SIP. Microsoft notes in its paper that, "The files and directories that are protected by SIP by default are commonly ones that are related to the system's integrity." And, what's more, it's impossible to turn off SIP on a live system, meaning it's always present and running. The security element is meant to protect macOS software by utilizing the Apple sandbox to lock down the system from root, such as a filesystem restriction element. With this vulnerability, attackers with root access on a machine can "automatically bypass" System Integrity Protection (SIP) and perform arbitrary operations on that device.Īpple first introduced SIP, or "rootless", with the launch of macOS Yosemite. On May 30, Microsoft published a new threat intelligence paper detailing a macOS vulnerability they call "Migraine," which they've already alerted Apple about. Microsoft identified a new macOS vulnerability called "Migraine" that can cause headaches for Mac users - but only if you haven't updated your software recently. ![]()
