Microsoft Threat Intelligence identified a macOS ClickFix operation distributing infostealers including MacSync and Atomic Stealer through over 250 algorithmically generated domains. The campaign evolved from openly displaying malicious content to implementing server-side browser fingerprinting that only reveals lures to visitors whose environment matches genuine macOS browsers. The fingerprinting gate collects browser attributes, hardware details via WebGL, and environmental characteristics to filter out crawlers and sandboxes. Victims are shown fake download pages with Terminal commands that retrieve remote scripts, ultimately deploying AMOS infostealer to harvest credentials, browser data, cryptocurrency wallets, and authentication stores. This Traffic Distribution System approach significantly reduces visibility for security researchers and automated analysis tools while maintaining access to intended targets. The operation represents a notable shift in tradecraft, adding sophistic...
