Clipboard Trap: ClickFix Now Abuses Windows Terminal to Deliver Lumma Stealer

A newly observed wave of ClickFix social-engineering attacks has shifted tactics, hijacking Windows Terminal as its execution environment to deliver credential-stealing malware. Security researchers from Microsoft and other vendors tracked this campaign in early 2026 and reported a reliable pattern: victims are manipulated into pasting an obfuscated command from their clipboard into a legitimate-looking terminal window, which then decodes and executes a multi-stage payload that ultimately harvests browser-saved credentials. Why…
