Domain or Tenant Policy Modification (T1484) é uma técnica catalogada no MITRE ATT&CK Enterprise usada como referência para mapear comportamento adversário em auditorias de segurança.

Técnica T1484 Enterprise ATT&CK

Contexto para AppSec

Em uma auditoria de AppSec, Domain or Tenant Policy Modification deve ser usada para revisar caminhos em que código, configuração, dependências ou infraestrutura podem viabilizar o comportamento descrito pela MITRE. No ATT&CK, ela aparece em Defense Impairment e Privilege Escalation. As plataformas mapeadas pela MITRE incluem Windows e Identity Provider. No Vigly, esse contexto ajuda a conectar evidências do repositório com priorização e remediação.

Descrição oficial original do MITRE ATT&CK

Adversaries may modify the configuration settings of a domain or identity tenant to evade defenses and/or escalate privileges in centrally managed environments. Such services provide a centralized means of managing identity resources such as devices and accounts, and often include configuration settings that may apply between domains or tenants such as trust relationships, identity syncing, or identity federation. Modifications to domain or tenant settings may include altering domain Group Policy Objects (GPOs) in Microsoft Active Directory (AD) or changing trust settings for domains, including federation trusts relationships between domains or tenants. With sufficient permissions, adversaries can modify domain or tenant policy settings. Since configuration settings for these services apply to a large number of identity resources, there are a great number of potential attacks malicious outcomes that can stem from this abuse. Examples of such abuse include: * modifying GPOs to push a malicious Scheduled Task to computers throughout the domain environment

  • modifying domain trusts to include an adversary-controlled domain, allowing adversaries to forge access tokens that will subsequently be accepted by victim domain resources
  • changing configuration settings within the AD environment to implement a Rogue Domain Controller.
  • adding new, adversary-controlled federated identity providers to identity tenants, allowing adversaries to authenticate as any user managed by the victim tenant Adversaries may temporarily modify domain or tenant policy, carry out a malicious action(s), and then revert the change to remove suspicious indicators.
