Storm-0426

Also known asStorm-0426

Storm-0426 is a Microsoft-tracked threat cluster associated with large-scale phishing activity using the ClickFix social engineering methodology. Microsoft observed the actor in March 2025 launching a phishing campaign targeting users in Germany and attempting to install MintsLoader. The emails used payment and invoice lures and redirected victims through the Prometheus traffic direction system hosted on compromised sites to mein-lonos-cloude[.]de. Microsoft also included Storm-0426 among threat clusters that have conducted large-scale phishing and malvertising campaigns utilizing ClickFix. ClickFix activity associated with this cluster involves fake verification or error-repair prompts that trick users into manually executing malicious commands, typically via the Windows Run dialog, Windows Terminal, or PowerShell, to deliver malware. No additional aliases or sub-groups were provided in the content beyond Storm-0426 / storm_0426.
