Cybersecurity researcher at Google's Project Zero division has publicly disclosed details and proof-of-concept exploit of a high-severity security vulnerability in macOS operating system after Apple failed to release a patch within 90 days of being notified. Discovered by Project Zero researcher Jann Horn and demonstrated by Ian Beer, the vulnerability resides in the way macOS XNU kernel allows an attacker to manipulate filesystem images without informing the operating system. The flaw could eventually allow an attacker or a malicious program to bypass the copy-on-write (COW) functionality to cause unexpected changes in the memory shared between processes, leading to memory corruption attacks. Copy-On-Write, also referred to as COW, is a resource-management optimization strategy used in computer programming. In general, if any process (destination) requires a file or data that is already in the memory but created by another process (source), both processes can share the ...

The same day Apple released its latest macOS Mojave operating system, a security researcher demonstrated a potential way to bypass new privacy implementations in macOS using just a few lines of code and access sensitive user data. On Monday, Apple started rolling out its new macOS Mojave 10.14 operating system update to its users, which includes a number of new privacy and security controls, including authorization prompts. Mojave 10.14 now pops up authorization prompts that require direct and real user interaction before any unprivileged third-party application can tap into users' sensitive information, such as address books, location data, message archives, Mail, and photos. Patrick Wardle, an ex-NSA hacker and now chief research officer at Digita Security, discovered a zero-day flaw that could allow an attacker to bypass authorization prompts and access users' personal information by using an unprivileged app. Wardle tweeted a video Monday showing how he was able ...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...
