What does this checker look at?

Visible attachment names, risky extension patterns, password-plus-archive wording, and URL shapes in the pasted text. It does not execute files, download parts, or scan binaries.

Does this replace antivirus or mail security tools?

No. It is a quick indicator pass for pasted text. Use endpoint and mail security products for real malware analysis.

The email headers and body as text (e.g. from View source). There is no file upload; paste content only.

Email Message Threat Checker

Paste full message text to surface attachment-name and link-shape risk indicators without opening files or following URLs.

This tool scans pasted text for risky filename extensions, double-extension tricks, password-plus-archive wording, and URL patterns (shorteners, credentials in URLs, IP hosts). It never opens attachments, fetches links, or replaces antivirus.

TL;DR: Paste raw message → review flags → verify through your normal security process; a quiet result is not a clean bill of health.

When to use

Use when triaging suspicious inbound mail before opening attachments or clicking links — indicator-only, not a malware verdict.

Use cases

Screen a forwarded thread before downloading a “shipping notice” attachment.
Review invoice-themed mail that bundles a ZIP and “password” in the body.
Check marketing-looking mail that hides a URL behind a short link.

What this tool checks

Dangerous or uncommon executable-like attachment extensions in visible names.
Double-extension patterns that try to look like a benign document.
Password or passcode text paired with archive filenames (ZIP/RAR/7Z) — common in staged payloads.
Link-shape cues (URL shorteners, userinfo in URLs, raw IP hosts) without fetching remote content.

Example result

Input: sample entity
Outcome: Medium risk
Top signals: identity mismatch, urgency cues
Recommended action: pause and verify independently

Common errors and flags

Treating “no flags” as proof the message is safe — indicators can miss well-crafted content.
Pasting only a From address instead of headers plus body — paste the full message text.
Expecting malware removal or a guarantee — this is triage only.

Decision guidance

Low risk outcome

Proceed with standard workflow and keep a basic audit trail.

Medium risk outcome

Pause and add one independent verification step before approval.

High risk outcome

Do not proceed. Escalate to fraud, security, or compliance review.

Trust workflow

Run this checker on raw input before user-facing action.
Review trust signals and flagged inconsistencies, not only final score.
Apply decision guidance and document why you approved, paused, or blocked.
Run related tools when the request includes payment, identity, or urgency pressure.
