But Apple confirmed to TechCrunch that it fixed the bug in macOS 11.4, which was made available as an update today. It’s not clear how many Macs the malware was able to infect using this technique. In other words, the bug could have been used to access the victim’s microphone, webcam or capture their keystrokes, such as passwords or credit card numbers. The researchers said that the malware used the permissions prompt bypass “specifically for the purpose of taking screenshots of the user’s desktop,” but warned that it was not limited to screen recording. Then, the malware signs the new app bundle with a new certificate to avoid getting flagged by macOS’ built-in security defenses.

This allows the malicious code to “piggyback” the legitimate app and inherit its permissions across macOS. Jamf researchers Jaron Bradley, Ferdous Saljooki, and Stuart Ashenbrenner explained in a blog post, shared with TechCrunch, that the malware searches for other apps on the victim’s computer that are frequently granted screen-sharing permissions, like Zoom, WhatsApp and Slack, and injects malicious screen recording code into those apps. But the malware bypassed that permissions prompt by sneaking in under the radar by injecting malicious code into legitimate apps. MacOS is supposed to ask the user for permission before it allows any app - malicious or otherwise - to record the screen, access the microphone or webcam, or open the user’s storage.

Once the malware is running on a victim’s computer, it uses two zero-days - one to steal cookies from the Safari browser to get access to a victim’s online accounts, and another to quietly install a development version of Safari, allowing the attackers to modify and snoop on virtually any website.īut Jamf says the malware was exploiting a previously undiscovered third zero-day in order to secretly take screenshots of the victim’s screen. By infecting those app development projects, developers unwittingly distribute the malware to their users, in what Trend Micro researchers described as a “supply-chain-like attack.” The malware is under continued development, with more recent variants also targeting Macs running the newer M1 chip. XCSSET was first discovered by Trend Micro in 2020 targeting Apple developers, specifically their Xcode projects that they use to code and build apps. Im notice when Ive have installed the Xcode 6 (GM) and I load a project from Xcode5, in the Images.xcassets file the 3x option is not shown for any image with Universal Devices. Lets assume for this example we call these catalogs MediaForDebug.xcassets, MediaForAdHoc.xcassets and MediaForRelease.xcassets. Jamf says it found evidence that the XCSSET malware was exploiting a vulnerability that allowed it access to parts of macOS that require permission - such as accessing the microphone, webcam or recording the screen - without ever getting consent. This is what you can do to make this work: Add a separate asset catalog per configuration, just as you would normally add an asset catalog to your project. Edit it like you would in Interface Builder. In Xcode, go to File > New File > Launch Screen (Under the User Interface header) > then all the usual location and target adding bits.

Now, some of the same researchers say another malware can sneak onto macOS systems, thanks to another vulnerability. So itll work with the iPad Pro sizes 9.7' 2048 x 1536px and 12.9', 2732 x 2048px.

But images arent coming where I placed them in xibs. I can quite see the xibs + view controller classes rendering view controllers though they reside inside bundle & framework, respectively. Important: With the newer Xcode 15 variant, the first letter of your color name is lowercased to fit in with standard Swift naming conventions, but if you’re using the older stringly-typed approach you should keep the casing the same as it is in your asset catalog.Almost exactly a month ago, researchers revealed a notorious malware family was exploiting a never-before-seen vulnerability that let it bypass macOS security defenses and run unimpeded. Their images reside in xcasset files of the framework project. If you’re using Xcode 14 and earlier, you need to write the name of your colors like this: Color('YourColorName') This was introduced in Xcode 15 alongside iOS 17, but works just fine back in all older versions of iOS. Then, in AppDelegate inside didFinishLaunchingWithOptions. In the Launch Images Source I choose Launch Images. Helpfully, it’s trivial to load an asset catalog color into a SwiftUI Color, and in fact if you’re using Xcode 15 or later you can write this: Color(.yourColorName) I have a Images.xcasset with 2 diferent Launch Images: LaunchImage and LaunchImage2.

How to load custom colors from an asset catalogĬreating your SwiftUI colors in an asset catalog is the easiest way to visualize them, but also the easiest way to add light and dark mode adjustments.
