Event

Creates a new user account in Microsoft Entra ID.

  • Account manipulation is a primary persistence technique, allowing adversaries to maintain access through modified permissions or credentials.
  • Creating cloud accounts provides a durable backdoor that persists independently of any compromised user’s credentials.

MITRE ATT&CK Mapping

Tactics: Persistence

Techniques:
  • T1136.003 — Cloud Account — Adversaries may create a cloud account to maintain access to victim systems. With a sufficient level of access, such accounts may be used to establish secondary credentialed access that does not require persistent remote access tools to be deployed on the system.
  • T1098 — Account Manipulation — Adversaries may manipulate accounts to maintain and/or elevate access to victim systems. Account manipulation may consist of any action that preserves or modifies adversary access to a compromised account, such as modifying credentials or permission groups. These actions could also include accoun...
