Apple macOS High Sierra Exploit Lets Hackers Steal Keychain Passwords in Plaintext

Apple macOS High Sierra Exploit Lets Hackers Steal Keychain Passwords in Plaintext
Sep 26, 2017
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

Critical OS X Flaw Grants Mac Keychain Access to Malware

Critical OS X Flaw Grants Mac Keychain Access to Malware
Sep 03, 2015
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

How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl
Mar 21, 2024SaaS Security / Endpoint Security
In today's digital-first business environment dominated by SaaS applications, organizations increasingly depend on third-party vendors for essential cloud services and software solutions. As more vendors and services are added to the mix, the complexity and potential vulnerabilities within the  SaaS supply chain  snowball quickly. That's why effective vendor risk management (VRM) is a critical strategy in identifying, assessing, and mitigating risks to protect organizational assets and data integrity. Meanwhile, common approaches to vendor risk assessments are too slow and static for the modern world of SaaS. Most organizations have simply adapted their legacy evaluation techniques for on-premise software to apply to SaaS providers. This not only creates massive bottlenecks, but also causes organizations to inadvertently accept far too much risk. To effectively adapt to the realities of modern work, two major aspects need to change: the timeline of initial assessment must shorte
