Apple has released its first Background Security Improvements update to fix a WebKit flaw tracked as CVE-2026–20643 on iPhones, iPads, and Macs without requiring a full operating system upgrade.
The CVE-2026–20643 flaw allows malicious web content to bypass the browser’s Same Origin Policy.
Apple says the flaw is a cross-origin issue in the Navigation API that was addressed with improved input validation.
To establish persistence, the LNK files are copied to the Windows Startup folder so that they are automatically launched following a system reboot. The attack chain then displays a URL containing lures related to installing Starlink or a Ukrainian charity named Come Back Alive Foundation.
The HTML file is eventually executed via the Microsoft Edge browser in headless mode, which then loads the remote obfuscated script hosted on Pastefy.
The browser is executed with additional parameters like –no-sandbox, –disable-web-security, –allow-file-access-from-files, –use-fake-ui-for-media-stream, –auto-select-screen-capture-source=true, and –disable-user-media-security, granting it access to the local file system, as well as camera, microphone, and screen capture without requiring any user interaction.
Microsoft is investigating a new issue affecting some Samsung laptops running Windows 11 after installing the February 2026 security updates, in which users lose access to their C:\ drive and are unable to launch applications.
The company says it is working with Samsung to determine whether the problem is related to the Windows updates or Samsung software installed on affected devices.
“Users might encounter the error, ‘C:\ is not accessible – Access denied’, which prevents access to files and blocks the launch of some applications including Outlook, Office apps, web browsers, system utilities and Quick Assist,” explains Microsoft.

Researchers have developed a technology to invisibly transmit information disguised as background thermal radiation. Using a phenomenon called “negative light,” they transferred 100 kilobits of data per second in a way that was completely undetectable to outside observers.
Most methods for concealing data during transfer involve hiding it among other data or encrypting it in a way that makes it impossible to read without a cipher or other means of decryption. The new technique, by contrast, makes the data almost impossible to intercept because there’s no indication it’s being sent at all. It can also be encrypted through traditional means to further harden security, the team wrote in a paper published March 5 in the journal Light: Science & Applications.
In this JACCBTS article, Joachimbauer et al. demonstrate that cardiopathogenic CD4+ T cells induce acute yet reversible inflammation-driven myocardial changes, and that the persistence of these cells is a key factor driving functional cardiac remodeling.
