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

1. Scope the task — define objectives, boundaries, and success criteria
2. Gather information — collect all necessary data and context before proceeding
3. Execute the core workflow — follow the domain-specific steps methodically
4. Validate results — verify outputs against expected outcomes or baselines
5. Document findings — record results, anomalies, and recommendations

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

When NOT to Use

• You need to test what you built (use performing-* skills)
• Task is about configuring existing systems (use configuring-* skills)
• You need to analyze the output (use analyzing-* skills)
• Task is about implementing vendor solutions (use implementing-* skills)
• You don't have infrastructure access
• Task requires compliance validation (use auditing-* skills)

Red Flags

• Performing actions without explicit written authorization from the asset owner
• Testing against production systems without a defined scope and rules of engagement
• Destroying potential evidence during the containment phase
• Failing to document the chain of custody for all collected artifacts
• Communicating incident details over unencrypted or monitored channels

Verification

• All steps executed successfully against a test environment before production use
• Output documented with screenshots or logs demonstrating expected behavior
• Timeline of events reconstructed with corroborating evidence
• Root cause identified and documented with contributing factors
• Post-incident review completed with lessons learned and action items

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

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
