ClickFix / FakeCaptcha PowerShell paste scam — email disguises as Cloudflare/Google/reCAPTCHA verification and instructs the victim to press Win+R or open PowerShell/terminal and paste a clipboard-injected command, silently running mshta/PowerShell to install stealer malware (CISA-flagged Q4 2025 → 2026)

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 disguised as a Cloudflare / Google / reCAPTCHA / Turnstile verification challenge that instructs the recipient to press Win+R (or open PowerShell / terminal) and paste a "verification code" — which is actually a clipboard-injected mshta.exe or PowerShell one-liner that downloads and executes stealer malware (Lumma, Vidar, DanaBot, AsyncRAT). CISA flagged ClickFix / FakeCaptcha as a top-5 initial-access technique in late 2025; volumes tripled quarter-over-quarter into Q1 2026. No legitimate captcha on the web requires running a command in PowerShell — an instruction to paste anything into a terminal is, by construction, a compromise attempt.
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 2,143+ 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.
