You Should Know:
1. How to Run the DefenderXDR Scan
- Navigate to the provided Advanced Hunting link.
- Authenticate with your Microsoft DefenderXDR credentials.
- Execute the KQL query to analyze telemetry from the last 30 days.
2. Key KQL Commands for Threat Hunting
Here are some essential KQL commands to enhance your DefenderXDR investigations:
Basic Query Structure
SecurityEvent | where TimeGenerated > ago(30d) | where EventID == 4688 // Process creation | project TimeGenerated, Computer, AccountName, ProcessName, CommandLine
Detecting Suspicious PowerShell Activity
DeviceProcessEvents | where FileName =~ "powershell.exe" | where ProcessCommandLine has "Invoke-Mimikatz" or ProcessCommandLine has "IEX" | project Timestamp, DeviceName, InitiatingProcessFileName, ProcessCommandLine
Identifying Lateral Movement via RDP
SecurityEvent
| where EventID == 4624 // Successful logon
| where LogonType == 10 // RemoteInteractive (RDP)
| where AccountName !in ("SYSTEM", "NETWORK SERVICE")
| summarize count() by AccountName, SourceIPAddress
Hunting for Fileless Attacks
DeviceEvents | where ActionType == "ExploitGuardWerdBlocked" | join kind=inner (DeviceFileEvents) on DeviceId | project Timestamp, DeviceName, FileName, FolderPath
3. Automating DefenderXDR Scans
Use PowerShell to schedule automated KQL queries:
Connect to DefenderXDR Connect-ExchangeOnline -UserPrincipalName "[email protected]" Run KQL query via API $query = @" DeviceProcessEvents | where FileName =~ "cmd.exe" | where ProcessCommandLine contains "net user" "@ Invoke-AdvancedHuntingQuery -Query $query
4. Exporting & Analyzing Results
- Export results to CSV for further analysis:
SecurityAlert | where TimeGenerated > ago(7d) | summarize Alerts=count() by AlertName | export to csv "DefenderAlerts.csv"
What Undercode Say
The One-Click DefenderXDR Scan simplifies threat detection by leveraging KQL, a powerful query language for security analytics. By integrating automated scans with PowerShell and Defender APIs, organizations can proactively detect anomalies, lateral movement, and fileless attacks.
Expected Output:
- Threat Detection Report (CSV/JSON)
- Suspicious Process Logs
- RDP Lateral Movement Alerts
- PowerShell Attack Patterns
For continuous monitoring, consider scheduling KQL queries and integrating them with SIEM solutions like Azure Sentinel.
Prediction
As AI-driven security analytics evolve, expect DefenderXDR to introduce automated remediation based on KQL findings, reducing manual investigation time.
