There are no indications iLeakage has been exploited in the wild. Description: A type confusion issue was addressed with improved memory handling. Impact: Processing maliciously crafted web content may lead to code execution. (In an email sent five days after this post went live, a Google representative pointed out the obvious: the leakage is the result of the side-channel and WebKit behavior and Gmail is simply a hypothetical downstream target. Available for: macOS Big Sur and macOS Catalina. WebKit Integrate web content seamlessly into your app, and customize content interactions to meet your app’s needs. The researchers have successfully leveraged iLeakage to recover YouTube viewing history, the content of a Gmail inbox-when a target is logged in-and a password as it’s being autofilled by a credential manager. When visited by a vulnerable macOS or iOS device, the website uses JavaScript to surreptitiously open a separate website of the attacker’s choice and recover site content rendered in a pop-up window. Since updating to macOS Catalina l now have 2 surplus folders Preboot and Preboot 1 both dating back to 2017, although they dont seem to causing any problems they are annoying - can they be safely deleted. The researchers implement iLeakage as a website. The nearly endless stream of exploit variants has left chip makers-primarily Intel and, to a lesser extent, AMD-scrambling to devise mitigations. Description: A use after free issue was addressed with improved memory management. Apple is aware of a report that this issue may have been actively exploited. Impact: Processing maliciously crafted web content may lead to arbitrary code execution. The side channel in this case is speculative execution, a performance enhancement feature found in modern CPUs that has formed the basis of a wide corpus of attacks in recent years. Available for: macOS Big Sur and macOS Catalina. It does, however, require extensive reverse-engineering of Apple hardware and significant expertise in exploiting a class of vulnerability known as a side channel, which leaks secrets based on clues left in electromagnetic emanations, data caches, or other manifestations of a targeted system. And worse, it may have already been used in the real world, rather than just discovered by security researchers.Further Reading Intel SGX is vulnerable to an unfixable flaw that can steal crypto keys and moreiLeakage, as the academic researchers have named the attack, is practical and requires minimal resources to carry out. This means that no matter what browser you use on your iPhone, iPad, or Mac it’s possible for users to craft web content in such a way that it allows them to run anything on your device. It was added with the commit message 'Update WKWebView getUserMedia delegate to latest proposal,' by an Apple employee who works on the WebKit technology. Webkit is Apple’s web rendering engine, and it is required to be used by all browsers on iOS, iPadOS, and macOS not just Safari. 9to5Mac was able to confirm that the mentions of iOS 15 and macOS 12 were added to the open-source WebKit repository last month.
