Event

Permanently deletes an Azure Event Hub entity within a namespace.

Security Context

  • Impairing defenses allows adversaries to operate freely by removing security controls that would otherwise detect or block their activity.
  • Destructive deletion of cloud resources can cause significant operational disruption, data loss, and extended recovery times.

Log Source

Azure Activity Log

Sample Event

Adversarial. Compromised user draco@fantasticlogs.cloud deletes the Event Hub eh-occamy-activitylog inside the evhns-occamy-prod namespace. This Event Hub was the streaming destination for the production subscription’s Activity Log diagnostic settings — once deleted, the SIEM stops receiving Activity Log events in near-real-time. Maps to T1485 + T1685.

Tactics: Impact Defense Impairment

Techniques:
  • T1485 — Data Destruction — Adversaries may destroy data and files on specific systems or in large numbers on a network to interrupt availability to systems, services, and network resources. Data destruction is likely to render stored data irrecoverable by forensic techniques through overwriting files or data on local and r...
  • T1685 — Disable or Modify Tools — Adversaries may disable, degrade, or tamper with security tools or applications (e.g., endpoint detection and response (EDR) tools, intrusion detection systems (IDS), antivirus, logging agents, sensors, etc.) to impair or reduce visibility of defensive capabilities. This may include stopping spec...
