MacSync uses iCloud calendars to load payloads

📌 A new MacSync variant for macOS now leverages public iCloud calendar events to deliver follow-on payloads. Kaspersky found the Swift-based infostealer being distributed via ClickFix-style social engineering and fake apps, with a downloader extracting commands from calendar DESCRIPTION fields to fetch archives hosted on iCloud. The malware retains broad credential-stealing capabilities and added an Objective-C backdoor that persists via LaunchAgents, .zshrc changes, and Git hooks.
