Detection overview

Triggers

  • Unusual access or unexpected changes made to App Service deployment configurations.
  • API requests to retrieve deployment configuration credentials from a specific slot.

Possible Root Causes

  • Unauthorized Access: A user or service principal is accessing App Service credentials without authorization.
  • Malicious Code Execution: A compromised Azure Function instance is exposing credentials.
  • Misconfigured Security Settings: Deployment slot permissions are improperly configured, allowing unintended access.
  • Insider Threat or Compromised Account: An account with elevated privileges is accessing App Service deployment configuration credentials.
  • Legitimate Developer Activity: Developers retrieving App Service slot credentials for debugging or testing.
  • IT Maintenance: Administrators accessing App Service configurations for maintenance or troubleshooting.
  • Automated Processes: Scripts or tools used by authorized personnel to manage App Service deployments.

Business Impact

  • Unauthorized access to intellectual property, including configuration files.
  • Potential data breaches and unauthorized access to sensitive information, such as API keys and connection strings.
  • Compromise of the App Service environment, leading to potential Denial-of-Service (DoS) attacks or resource exhaustion.
  • Compliance and regulatory risks due to inadequate security controls.

Steps to Verify

  • Investigate the Deployment Slot: Analyze the specific slot and instance involved in the suspicious activity.
  • Review Azure Activity Logs: Check API requests and changes made to configurations or environment variables within the affected slot.
  • Analyze Recent Modifications: Verify recent updates or changes in App Service settings, permissions, or access control.
  • Conduct a Security Assessment: Perform vulnerability assessments and penetration testing on the affected App Service environment.
  • Validate Permissions: Review user and service principal permissions to identify potential security risks.
  • Monitor for Anomalies: Examine system logs for any suspicious activity or unexpected access patterns within the affected slot.
