UpdateAssumeRolePolicy

Event

Updates the trust policy of an IAM role, changing which principals are permitted to assume it.

Security Context

  • Adversaries attach overly permissive policies to maintain persistent, elevated access even after initial credentials are rotated.
  • Abusing elevation control mechanisms allows adversaries to bypass intended access restrictions and operate with higher privileges.

Tactics: Persistence Privilege Escalation

Techniques:
  • 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.
  • T1548 — Abuse Elevation Control Mechanism — Adversaries may circumvent mechanisms designed to control elevate privileges to gain higher-level permissions. Most modern systems contain native elevation control mechanisms that are intended to limit privileges that a user can perform on a machine.
