Google Discloses Unpatched 'High-Severity' Flaw in Apple macOS Kernel

Google Discloses Unpatched 'High-Severity' Flaw in Apple macOS Kernel

Mar 04, 2019
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

ex-NSA Hacker Discloses macOS Mojave 10.14 Zero-Day Vulnerability

Sep 27, 2018
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

Sailing the Seven Seas Securely from Port to Port – OT Access Security for Ships and Cranes

Oct 28, 2024Operational Technology / Cybersecurity
Operational Technology (OT) security has affected marine vessel and port operators, since both ships and industrial cranes are being digitalized and automated at a rapid pace, ushering in new types of security challenges. Ships come to shore every six months on average. Container cranes are mostly automated. Diagnostics, maintenance, upgrade and adjustments to these critical systems are done remotely, often by third-party vendor technicians. This highlights the importance of proper secure remote access management for industrial control systems (ICS).  Learn more in our Buyer's Guide for Secure Remote Access Lifecycle Management .  We at SSH Communications Security (SSH) have been pioneering security solutions that bridge the gap between IT and OT in privileged access management . Let's investigate how we helped two customers solve their critical access control needs with us. Secure Remote Access Around the Globe to 1000s of Ships  In the maritime industry, ensuring secure and e
