Microsoft Defender Phishing Simulation: A Deep Dive into Attack Simulations

Microsoft Defender for Office 365 offers powerful phishing simulation tools to test organizational security. This article explores its features, including realistic attack campaigns, credential harvesting tracking, and automated training recommendations.

You Should Know:

1. Setting Up a Phishing Simulation in Microsoft Defender

To launch a phishing simulation:

1. Access Microsoft 365 Defender Portal:

Connect-ExchangeOnline -UserPrincipalName [email protected]

2. Create a Simulation Campaign:

• Navigate to Attack simulation training > Simulations > + Create simulation.
• Select Phishing as the attack technique.

2. Crafting a Realistic Phishing Email

• Use Gift Card Lures (e.g., Amazon, Starbucks).
• Customize sender names to mimic trusted sources.
• Enable Credential Harvesting to track input submissions:

  New-AttackSimulationPhishing -Name "Amazon Gift Card Scam" -Payload "Amazon_GiftCard_Phish" -TargetUsers "All"
  

3. Monitoring User Interactions

• Check Click Rates and Compromised Users:

  Get-AttackSimulationReport -SimulationId "SIM_ID" -DetailLevel Full
  

• Export results for analysis:

  Export-AttackSimulationReport -SimulationId "SIM_ID" -Path "C:\Reports\Phish_Report.csv"
  

4. Automating Training for Vulnerable Users

• Assign Microsoft Security Training Modules:

  Start-AttackSimulationTraining -SimulationId "SIM_ID" -TrainingType "SelectedUsers" -UserIds "[email protected],[email protected]"
  

5. Optimizing Report Delays

• Use Log Analytics for real-time data:

  SecurityIncident
  | where ProviderName == "Microsoft Defender for Office 365"
  | where AttackTechnique == "Phishing"
  | summarize ClickCount=count() by UserEmail
  

What Undercode Say:

Microsoft Defender’s phishing simulation is a game-changer for security teams. However, delays in reporting can be mitigated via PowerShell automation and Azure Log Analytics. Key takeaways:
– Always test with non-admin accounts first.
– Combine simulations with conditional access policies:

New-ConditionalAccessPolicy -Name "Block Phish-Prone Users" -Users "HighRiskUsers" -BlockAccess

– Enhance Defender with SIEM integration (e.g., Sentinel).
