Mac OS X keychain | Breaking Cybersecurity News | The Hacker News

Apple yesterday rolled out a new version of its macOS operating system, dubbed High Sierra 10.13 —a few hours before an ex-NSA hacker publicly disclosed the details of a critical vulnerability that affects High Sierra as well as all earlier versions of macOS. Patrick Wardle, an ex-NSA hacker and now head of research at security firm Synack, found a critical zero-day vulnerability in macOS that could allow any installed application to steal usernames and plaintext passwords of online accounts stored in the Mac Keychain. The macOS Keychain is a built-in password management system that helps Apple users securely store passwords for applications, servers, websites, cryptographic keys and credit card numbers—which can be accessed using only a user-defined master password. Typically no application can access the contents of Keychain unless the user enters the master password. "I discovered a flaw where malicious non-privileged code (or apps) could programmatically access th...

Back in July, a security researcher disclosed a zero-day vulnerability in Mac OS X that allowed attackers to obtain unrestricted root user privileges with the help of code that even fits in a tweet . The same vulnerability has now been upgraded to again infect Mac OS X machines even after Apple fixed the issue last month. The privilege-escalation bug was once used to circumvent security protections and gain full control of Mac computers. Thanks to the environment variable DYLD_PRINT_TO_FILE Apple added to the code of OS X 10.10 Yosemite. The vulnerability then allowed attackers to install malware and adware onto a target Mac, running OS X 10.10 (Yosemite), without requiring victims to enter system passwords. However, the company fixed the critical issue in the Mac OS X 10.11 El Capitan Beta builds as well as the latest stable version of Mac OS X – Version 10.10.5 . Mac Keychain Flaw Now, security researchers from anti-malware firm MalwareBytes spotted t...

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...
