# Investigating Phishing Email Incident
## When to Use
Use this skill when:
- A user reports a suspicious email via the phishing report button or helpdesk ticket
- Email security gateway flags a message that bypassed initial filters
- Automated detection identifies credential harvesting URLs or malicious attachments
- A phishing campaign targeting the organization requires scope assessment
**Do not use** for spam or marketing emails without malicious intent — route those to email administration for filter tuning.
## Detection Gaps & Validation
- **Clean attachment, weaponized link:** triagers detonate the attachment, get a benign verdict, and close — missing that the body's credential-harvest URL is the real payload. Always extract and analyze every URL (including those inside PDFs, QR codes, and HTML attachments) even when the file sandboxes clean.
