# Building Phishing Reporting Button Workflow

## Overview
A phishing reporting button empowers users to flag suspicious emails directly from their email client, creating a critical feedback loop between end users and the security operations center. Microsoft's built-in Report button is now the recommended approach, replacing the deprecated Report Message and Report Phishing add-ins. When combined with automated triage using SOAR platforms, reported emails can be classified, IOCs extracted, and remediation actions taken within minutes. Organizations with effective phishing reporting programs see 70%+ report rates in phishing simulations.


## When to Use

- When deploying or configuring building phishing reporting button workflow capabilities in your environment
- When establishing security controls aligned to compliance requirements
- When building or improving security architecture for this domain
- When conducting security assessments that require this implementation

## Prerequisites
- Microsoft 365 or Google Workspace with administrative access
- SOAR platform or automation capability (Microsoft Sentinel, Splunk SOAR, Cortex XSOAR)
- Dedicated reporting mailbox for phishing submissions
- Email security gateway with message retraction capability
- Security awareness training platform for feedback loop

## Workflow

### Step 1: Deploy Phishing Report Button
- Enable Microsoft built-in Report button via Security & Compliance Center
- Configure user reported settings: route to reporting mailbox and Microsoft
- For third-party: deploy KnowBe4 Phish Alert Button or Cofense Reporter
- Verify button appears in Outlook desktop, web, and mobile clients
- Configure report options: Report Phishing, Report Junk, Report Not Junk

### Step 2: Build Automated Triage Pipeline
- Configure reporting mailbox monitored by SOAR platform
- Auto-extract IOCs from reported emails: URLs, attachments, sender info, headers
- Submit URLs to VirusTotal, URLScan.io for reputation check
- Submit attachments to sandbox for dynamic analysis
- Check sender against known threat intelligence feeds
- Auto-classify: confirmed phishing, spam, simulation, legitimate

### Step 3: Implement Response Actions
- Confirmed phishing: auto-retract from all inboxes, block sender domain
- Confirmed spam: move to junk for all recipients
- Simulation email: mark as correctly reported, credit user
- Legitimate email: return to inbox, notify reporter
- Generate IOC report for threat intelligence team

### Step 4: Create Feedback Loop
- Send automated thank-you response to reporter within 5 minutes
- Include classification result when analysis completes
- Track reporter accuracy and engagement metrics
- Recognize top reporters in monthly security newsletter
- Feed reporting metrics into security awareness training program

### Step 5: Measure and Optimize
- Track mean time to triage (target: under 10 minutes automated)
- Monitor report volume trends and false positive rates
- Measure user reporting rate in phishing simulations
- Report on confirmed threats caught by user reports vs. gateway
- Optimize automation rules based on classification accuracy

## Tools & Resources
- **Microsoft Report Button**: Built-in Outlook phishing reporting
- **Cofense Reporter + Triage**: Enterprise phishing reporting and automated analysis
- **KnowBe4 Phish Alert Button**: Integrated reporting with simulation platform
- **Microsoft Sentinel**: SOAR automation for triage workflow
- **Proofpoint CLEAR**: Closed-loop email analysis and response

## Validation
- Report button visible and functional across all Outlook platforms
- Reported email arrives in dedicated mailbox within 60 seconds
- Automated triage classifies test phishing email correctly
- Auto-retraction removes confirmed phishing from all inboxes
- Reporter receives feedback notification with classification
- Metrics dashboard shows report volume and accuracy trends

# Workflows: Building Phishing Reporting Button Workflow

## Workflow 1: Automated Phishing Report Triage

```
User clicks "Report Phishing" button
  |
  v
[Email forwarded to reporting mailbox]
  +-- Original email preserved with full headers
  +-- Reporter identity recorded
  |
  v
[SOAR platform ingests report]
  |
  v
[Automated IOC extraction]
  +-- Extract sender address and domain
  +-- Extract all URLs from body
  +-- Extract attachment hashes (MD5, SHA256)
  +-- Parse email headers for authentication results
  |
  v
[Automated analysis (parallel)]
  +-- URLs -> VirusTotal, URLScan.io, PhishTank
  +-- Attachments -> Sandbox detonation
  +-- Sender -> Threat intelligence lookup
  +-- Headers -> SPF/DKIM/DMARC validation
  |
  v
[Classification]
  +-- CONFIRMED PHISHING: High-confidence malicious
  +-- SUSPICIOUS: Moderate indicators, needs analyst review
  +-- SPAM: Unwanted but not malicious
  +-- SIMULATION: Matches internal phishing test
  +-- CLEAN: Legitimate email, false report
  |
  v
[Automated response by classification]
  +-- PHISHING: Retract from all inboxes + block sender
  +-- SUSPICIOUS: Escalate to SOC analyst
  +-- SPAM: Move to junk for all recipients
  +-- SIMULATION: Credit reporter in training platform
  +-- CLEAN: Return to inbox
  |
  v
[Feedback to reporter]
  +-- "Thank you for reporting" (immediate)
  +-- Classification result (when complete)
  +-- Training tip (if false positive)
```

## Workflow 2: SOC Analyst Escalation

```
SOAR classifies report as SUSPICIOUS
  |
  v
[SOC analyst reviews]
  +-- Examine full email content and headers
  +-- Verify automated analysis results
  +-- Check for similar reports from other users
  |
  v
[Analyst decision]
  +-- Confirm malicious --> Trigger remediation playbook
  +-- Confirm clean --> Close and notify reporter
  +-- Need more info --> Contact reporter for context
