Introduction:
For years, the offensive security community has enjoyed a wealth of Azure-focused certifications like AzRTS and MCRTA, but the blue team side—the threat hunters, the SOC analysts, the defenders—has been left with almost nothing purpose-built. CAzTH (Certified Azure Threat Hunter) from CyberWarFare Labs is the first certification to address this critical gap, offering a structured, hands-on path for professionals who need to detect, investigate, and respond to threats in Microsoft cloud environments. As Joas A Santos, Founder of RedTeamLeaders and Head of AI Research, put it: “I kept thinking; why hasn’t this existed sooner?”
Learning Objectives:
- Master threat hunting fundamentals and map adversary behaviors using the MITRE ATT&CK framework across Azure services.
- Configure Splunk SIEM and Azure Sentinel for comprehensive log ingestion, enabling real-time detection and investigation.
- Investigate real-world attack scenarios across Entra ID, Azure Resource Manager (ARM), and Microsoft 365, with hands-on containment and SOAR automation.
You Should Know:
- Understanding the CAzTH Certification and Its Core Modules
The CAzTH certification is built around five comprehensive modules designed to take a blue team professional from foundational concepts to advanced threat hunting in Azure environments. Unlike traditional certifications that focus on theory, CAzTH emphasizes practical, real-world Azure attack scenarios.
The curriculum covers:
- Threat hunting fundamentals + MITRE ATT&CK: Learn how to apply the MITRE ATT&CK framework to Azure-specific threats, mapping adversary behaviors to real-time activities across Azure services.
- Azure architecture for blue teamers: Understand the Azure control plane, data plane, and how administrative logs capture intent and authority—the single most important telemetry source for detecting control plane threats.
- Splunk SIEM setup for Azure log ingestion: Configure Splunk to ingest Azure Activity logs, Azure AD logs, and other critical telemetry sources.
- Real attack investigations: Dive into Entra ID (formerly Azure AD) attacks, ARM-based resource abuse, and M365 compromise scenarios.
- Containment, token revocation, and SOAR automation: Learn to respond decisively with automated playbooks and identity threat detection and response (ITDR) strategies.
Step‑by‑step: Getting Started with Azure Threat Hunting
- Set Up Your Azure Log Analytics Workspace: Navigate to the Azure portal, create a Log Analytics workspace, and enable Microsoft Sentinel on that workspace.
- Connect Data Connectors: Use the Azure Activity data connector to ingest subscription-level activity logs. Also connect Microsoft 365 Defender and Entra ID audit logs.
- Deploy a Threat Hunting Framework: Use the Sentinel ATT&CK ARM template to automatically deploy 117 ready-to-use Kusto detection rules covering 156 ATT&CK techniques.
- Start Hunting: Use the hunting queries tab in Microsoft Sentinel to identify spikes, anomalies, and MITRE ATT&CK technique mappings.
-
Setting Up Splunk SIEM for Azure Log Ingestion
While Microsoft Sentinel is the native SIEM for Azure, many organizations standardize on Splunk. CAzTH covers Splunk configuration for Azure log ingestion, giving you flexibility in enterprise environments.
Step‑by‑step: Splunk Azure Log Ingestion
- Install the Splunk Add-on for Microsoft Cloud Services: Download and install the add-on from Splunkbase.
- Configure Azure AD App Registration: Create a service principal in Entra ID with permissions to read audit logs and sign-in logs.
- Set Up Inputs in Splunk: Navigate to the add-on configuration and add inputs for:
– Azure Activity Logs (subscription-level)
– Azure AD Audit Logs
– Azure AD Sign-in Logs
– Microsoft 365 Unified Audit Logs
4. Validate Data Flow: Use Splunk search to verify logs are arriving: `index=azure sourcetype=mscs:azure:activity`
5. Create Alerts and Dashboards: Build dashboards for failed sign-ins, privileged role assignments, and anomalous resource creation.
Linux Command Example – Azure CLI Log Collection:
Install Azure CLI
curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash
Login to Azure
az login
Download activity logs for the last 24 hours
az monitor activity-log list --start-time $(date -d '24 hours ago' -Iseconds) --output json > azure_activity_logs.json
Use jq to filter for specific events (e.g., role assignments)
cat azure_activity_logs.json | jq '.[] | select(.operationName.value | contains("Microsoft.Authorization/roleAssignments/write"))'
Windows PowerShell Command – Azure AD Log Collection:
Install the Azure AD module Install-Module -1ame AzureAD -Force Connect to Azure AD Connect-AzureAD Get audit logs for the last 7 days $auditLogs = Get-AzureADAuditDirectoryLogs -Top 1000 $auditLogs | Export-Csv -Path "C:\Security\AzureAD_AuditLogs.csv" -1oTypeInformation
- Threat Hunting in Entra ID (Azure AD) – Identity Attacks and Detection
Entra ID is the identity backbone of Azure, making it a prime target for attackers. Common attack vectors include password spray, token replay, and privilege escalation. CAzTH teaches you to detect and respond to these threats.
Step‑by‑step: Hunting Entra ID Attacks
- Enable Entra ID Identity Protection: In the Azure portal, navigate to Entra ID > Security > Identity Protection. Ensure risk policies are enabled for user and sign-in risks.
- Monitor for Password Spray Attacks: Use Entra ID Protection’s detection mechanisms to identify “password spray” type attacks. Look for multiple failed sign-ins from a single IP across many accounts.
- Detect Token Replay and Device Registration Abuse: Attackers use tools like ROADtools to interact with Entra ID via legitimate APIs, register devices, and replay stolen tokens. Hunt for anomalous device registration events and token usage patterns.
- Investigate Privileged Role Assignments: Use Azure Activity logs to detect unexpected role assignments. Query for `Microsoft.Authorization/roleAssignments/write` operations.
Kusto Query Language (KQL) for Entra ID Threat Hunting:
// Detect multiple failed sign-ins from a single IP SigninLogs | where ResultType == "50057" // User account is disabled | summarize FailedAttempts = count() by IPAddress, UserPrincipalName | where FailedAttempts > 10 | project IPAddress, UserPrincipalName, FailedAttempts // Detect anomalous device registration AuditLogs | where OperationName == "Add device" | extend DeviceId = tostring(TargetResources[bash].id) | extend UserAgent = tostring(InitiatedBy.user.userAgent) | where UserAgent contains "ROADtools" or UserAgent contains "custom"
4. Investigating Azure Resource Manager (ARM) Threats
ARM is the control plane for Azure resources. Attackers who compromise an Azure subscription can create, modify, or delete resources at scale. CAzTH teaches you to hunt for ARM-based TTPs (Tactics, Techniques, and Procedures).
Step‑by‑step: ARM Threat Hunting
- Enable Azure Activity Logs: Ensure Activity Logs are being sent to your Log Analytics workspace.
- Create Analytic Rules in Microsoft Sentinel: Use the Azure Activity connector to create analytic rules that trigger on suspicious resource creation. For example, detect “Creation of an anomalous number of resources”.
- Hunt for Resource Hijacking: Use Azure Sentinel hunting queries to identify potential resource hijacking based on anomalies in access and usage patterns.
- Investigate Control Plane Changes: Administrative logs capture who made what change and under which context. Review these logs for unauthorized changes to security groups, firewall rules, or key vaults.
KQL for ARM Threat Hunting:
// Detect anomalous number of resource creations AzureActivity | where OperationName == "Microsoft.Resources/deployments/write" | summarize ResourceCreations = count() by Caller, bin(TimeGenerated, 1h) | where ResourceCreations > 50 // Detect suspicious role assignments AzureActivity | where OperationName == "Microsoft.Authorization/roleAssignments/write" | extend RoleDefinition = tostring(Properties.roleDefinitionId) | extend PrincipalId = tostring(Properties.principalId) | project TimeGenerated, Caller, RoleDefinition, PrincipalId
5. Containment, Token Revocation, and SOAR Automation
Once a threat is detected, rapid containment is critical. CAzTH covers token revocation, identity isolation, and SOAR (Security Orchestration, Automation, and Response) automation.
Step‑by‑step: Incident Response in Azure
- Revoke Sessions and Tokens: Use PowerShell to revoke all sessions for a compromised user:
Revoke-AzureADUserAllRefreshToken -ObjectId "[email protected]"
- Block Sign-in: In Entra ID, block the compromised user account to prevent further access.
- Isolate Compromised Resources: Use Azure Policy or Azure Security Center to isolate affected VMs or resources.
- Automate Response with Logic Apps: Create a playbook in Microsoft Sentinel that triggers on high-severity alerts. The playbook can automatically revoke tokens, block IPs, and send notifications to the SOC team.
- Conduct Post-Incident Review: Analyze the attack path and update detection rules to prevent recurrence.
Linux Command – Azure CLI for Token Revocation:
Revoke all sessions for a user (requires Azure AD module) az ad user update --id [email protected] --account-enabled false
What Undercode Say:
- Key Takeaway 1: The CAzTH certification fills a critical void in the Azure security ecosystem. While Azure red team certifications have flourished, blue team professionals have lacked a purpose-built credential that focuses on threat hunting and detection.
- Key Takeaway 2: The certification’s emphasis on real-world attack scenarios—Entra ID, ARM, M365—ensures that graduates can immediately apply their skills in enterprise environments. The inclusion of SIEM setup, SOAR automation, and containment techniques makes it a comprehensive program for SOC analysts and threat hunters.
Analysis: The cybersecurity industry has long recognized the “purple team” approach—where offensive and defensive mindsets converge—as the gold standard for cloud security. CAzTH directly supports this by equipping blue teamers with the knowledge to understand how attackers operate while building robust detection and response capabilities. As Joas A Santos noted, understanding both how attackers operate and how defenders detect and respond is what creates truly effective cloud security professionals. This certification is not just another credential; it represents a shift toward practical, adversary-informed defense in Microsoft cloud environments.
