Apple’s New OS Has Severe Security Flaw

Apple’s New OS Has Severe Security Flaw

MacOS Mojave shipped with a bug that allows unauthorized access to a user’s private data.

Apple’s new version of macOS, chock full of new features, also appears to feature a bug that makes users’ private data vulnerable. This bug, found by security researcher Patrick Wardle, allows simple bypass programs to circumvent the computer’s privacy access controls — no permission needed.

In a post to Twitter, Wardle showcased his hack, alongside announcing he had found a day-zero vulnerability in the operating system. In the short video, he runs his bypass program “breakMojave” and proceeds to make good on the program’s name, using it to locate the user’s address book and copy the contents to his desktop.

Wardle called the vulnerability a “trivial, albeit 100% reliable flaw in their implementation.”

Apple addressed a number of security flaws with Mojave’s release, including vulnerabilities in Bluetooth and the application firewall. However, this new flaw, found hours before the OS was released to the public, has not been addressed yet at time of writing. No technical details were released alongside the announcement, to prevent hackers with less benevolent intentions from repeating his processes.

Wardle, who has worked at NASA and the NSA in the past, now works finding MacOS security flaws at Digita Security, of which he is a co-founder.

Every company has unique surveillance requirements that are based on market focus, scale, scope, risk tolerance, geographic area and, of course, budget. Those factors all play a role in deciding how to configure a surveillance system, and how to effectively implement technologies like AI. Read Now

  • 6 Ways Security Awareness Training Empowers Human Risk Management

    Organizations are realizing that their greatest vulnerability often comes from within – their own people. Human error remains a significant factor in cybersecurity breaches, making it imperative for organizations to address human risk effectively.

  • The Stage is Set

    The security industry spans the entire globe, with manufacturers, developers and suppliers on every continent (well, almost—sorry, Antarctica). That means when regulations pop up in one area, they often have a ripple effect that impacts the entire supply chain. Recent data privacy regulations like GDPR in Europe and CPRA in California made waves when they first went into effect, forcing businesses to change the way they approach data collection and storage to continue operating in those markets. Even highly specific regulations like the U.S.’s National Defense Authorization Act (NDAA) can have international reverberations – and this growing volume of legislation has continued to affect global supply chains in a variety of different ways.
