iOS Kernel | Breaking Cybersecurity News | The Hacker News

As promised last week , Google's Project Zero researcher Ian Beer now publicly disclosed an exploit that works on almost all 64-bit Apple devices running iOS 11.1.2 or earlier, which can be used to build an iOS jailbreak, allowing users to run apps from non-Apple sources. On Monday morning, Beer shared the details on the exploit, dubbed "tfp0," which leveraged double-free memory corruption vulnerabilities in the kernel, the core of the operating system. Here, " tfp0 " stands for " task for pid 0 " or the kernel task port—which gives users full control over the core of the operating system. The Project Zero researcher responsibly reported these vulnerabilities to Apple in October, which were patched by the company with the release of iOS 11.2 on 2nd December. While Beer says he has successfully tested his proof of concept exploit on the iPhone 6s and 7, and iPod Touch 6G, he believes that his exploit should work on all 64-bit Apple devices. ...

Apple's new iOS 10 recently made headlines after MIT Technology Review revealed that the company had left the kernel of the mobile operating system unencrypted. Yes, the first developer preview of iOS 10 released at WWDC has an unencrypted kernel. When the headline broke, some of the users were surprised enough that they assumed Apple had made a mistake by leaving unencrypted kernel in iOS 10, and therefore, would get reverted in the next beta version of the operating system. However, Apple managed to confirm everyone that the company left the iOS 10 kernel unencrypted intentionally, as the kernel cache does not contain any critical or private information of users. On iOS, the kernel is responsible for things like security and how applications are capable of accessing the parts of an iPhone or an iPad. But, Why Apple had left the iOS wide open when other features like iMessage offer end-to-end encryption ? Apple did this on purpose, because by leaving the iOS 10 kernel ...

When people think of cybersecurity threats, they often picture external hackers breaking into networks. However, some of the most damaging breaches stem from within organizations. Whether through negligence or malicious intent, insiders can expose your organization to significant cybersecurity risks. According to Verizon's 2024 Data Breach Investigations Report , 57% of companies experience over 20 insider-related security incidents a year, with human error involved in 68% of data breaches. With that, insider attacks result in the highest costs, averaging USD 4.99 million per attack, as per the 2024 Cost of a Data Breach Report by IBM Security.  What are insider threats? An insider threat originates from within an organization – it's the potential for anyone with authorized access to your critical systems to misuse their access, harming your organization. The worst part is that insiders are already within your IT perimeter and are familiar with your internal security prot...
