This Mac malware is somehow using iCloud calendar invites to try and steal your data

Cybercriminals have developed an infostealer called MacSync, targeting Mac devices by using iCloud calendar events and cloud storage. This malware disguises itself as fake cryptocurrency wallets and pirated software. It begins with a loader that retrieves instructions from calendar entries and deploys malware to exfiltrate sensitive information, including credentials and cryptocurrency wallets. Recent versions have introduced an Objective-C backdoor that mimics Finder. Victims are often tricked into downloading these malicious applications, and effective antivirus solutions can prevent damage. Cybercriminals use tactics like SEO poisoning and phishing to direct victims to fraudulent websites or social media promoting pirated software. In one case, the loader was marketed as a cryptocurrency wallet, and victims encountered a misleading ClickFix error message that prompted them to execute a command in the Terminal.

Lock down your Windows 11 taskbar so no one else can change it

Administrators can manage taskbar settings in Windows by either freezing current configurations or restricting user modifications through the Registry or Group Policy. The Group Policy Editor is available in Windows Professional, Education, and Business editions. To lock down taskbar changes via the Registry, access the Registry Editor, navigate to HKEYCURRENTUSERSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorer, create a new DWORD (32-bit) value named TaskbarLockAll, set its value to 1, and confirm. This will grey out certain options in the Taskbar settings. In the Group Policy Editor, navigate to User Configuration → Administrative Templates → Start Menu and Taskbar, enable "Lock all Taskbar Settings," and confirm. To prevent standard users from altering taskbar settings, navigate to HKEYCURRENTUSERSoftwarePoliciesMicrosoftWindowsExplorer in the Registry and create a new DWORD (32-bit) value.

Patch Tuesday is here — Windows 11 is expected to set yet another record for security updates in a month

Windows 11's latest Patch Tuesday delivered over 650 security fixes, a six-fold increase compared to typical monthly updates. This surge is linked to advancements in artificial intelligence, which have accelerated vulnerability discovery and the urgency to address them. AI aids Microsoft's engineers in the patching process but is also exploited by malicious actors, creating an ongoing cybersecurity arms race.

Microsoft never learns, IT admins rage as a new OneDrive app invades Windows 11 and keeps coming back when you remove it

Microsoft has begun silently installing the "OneDrive Photos" app on Windows PCs, including enterprise systems managed via Microsoft Intune, without prior notification. IT professionals have expressed significant frustration over this unexpected addition, noting that the app is incompatible with Entra accounts and cannot be removed without uninstalling OneDrive entirely. The app functions as a web-based gallery feature, indexing and displaying photos stored on local machines, but its necessity is questioned due to the existing Microsoft Photos app. OneDrive Photos is linked to the OneDrive sync client, making it impossible to uninstall independently. Users have reported that the app appears in Windows Search results with an 'Uninstall' option but does not show up in the Installed apps page, leading to confusion. A script has been developed to remove the shortcut, but it often reappears due to its connection with the OneDrive sync client. Discussions with Microsoft suggest that the rollout may have been unintended, with an apology expected soon.
