FileFix address-bar paste lure — mr.d0x ClickFix variant targeting Windows File Explorer: email instructs victim to press Ctrl+L (or click "Open File Explorer"), paste a disguised PowerShell/mshta command into the address bar, and press Enter. Payload is whitespace-padded so only a fake file path shows in the UI (Check Point + Kaspersky + Intel 471 + BleepingComputer Jun 2025 → Mar 2026; Expel Labs cache-smuggling variant Dec 2025; StealC v2 payload)

What this tier means
High-confidence threat indicator — phishing, impersonation, BEC, or scam pattern. Strong contributor to the trash decision.
How Gorganizer detects this
Email directing the recipient to press Ctrl+L in Windows File Explorer (or click "Open File Explorer"), then paste a "file path" into the address bar and press Enter. The pasted string is a disguised PowerShell, mshta, or rundll32 one-liner: the real payload is prefixed with hundreds of whitespace characters so the UI only shows a fake-looking path (`\\server\team\docs\report.pdf`) while Enter executes the command. FileFix was disclosed by mr.d0x in June 2025 and turned up in live campaigns within two weeks — documented by Check Point, Kaspersky, Intel 471, BleepingComputer. Expel Labs disclosed a cache-smuggling variant with a JPG-hidden PowerShell payload dropping StealC v2 in December 2025; FileFix 2.0 with Mark-of-the-Web bypass landed by March 2026. Distinct from the Win+R ClickFix family because the UI affordance is different (File Explorer rather than the Run dialog). No legitimate workflow requires pasting anything into File Explorer's address bar to "open" an email attachment.
False-positive guard
Every signal in Gorganizer feeds a multi-module score — never a sole verdict. This is a threat-tier signal — it adds a strong contribution to the trash score. The full pipeline still requires convergence across multiple modules + a margin over the safety floor before deletion happens, and Gmail's trash (30-day recovery) is always used — never permanent delete.
About the scoring engine
Gorganizer's scoring engine emits over 1,800 signals across six modules — headers, sender, subject, body, attachments, and structural metadata. Every email is scored by every module independently; the final verdict requires multiple modules to agree and the trash score to beat the safety floor by a margin.
Sacred safety guards — never delete starred emails, replies, calendar invites, receipts/invoices, or attachments — apply unconditionally regardless of any signal.
