T1059.009: Cloud API
Cloud API (T1059.009) é uma técnica catalogada no MITRE ATT&CK Enterprise usada como referência para mapear comportamento adversário em auditorias de segurança.
Contexto para AppSec
Em uma auditoria de AppSec, Cloud API 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 Execution. As plataformas mapeadas pela MITRE incluem IaaS, Identity Provider, Office Suite e SaaS. No Vigly, esse contexto ajuda a conectar evidências do repositório com priorização e remediação.
Descrição oficial original do MITRE ATT&CK
Adversaries may abuse cloud APIs to execute malicious commands. APIs available in cloud environments provide various functionalities and are a feature-rich method for programmatic access to nearly all aspects of a tenant. These APIs may be utilized through various methods such as command line interpreters (CLIs), in-browser Cloud Shells, PowerShell modules like Azure for PowerShell, or software developer kits (SDKs) available for languages such as Python. Cloud API functionality may allow for administrative access across all major services in a tenant such as compute, storage, identity and access management (IAM), networking, and security policies. With proper permissions (often via use of credentials such as Application Access Token and Web Session Cookie), adversaries may abuse cloud APIs to invoke various functions that execute malicious actions. For example, CLI and PowerShell functionality may be accessed through binaries installed on cloud-hosted or on-premises hosts or accessed through a browser-based cloud shell offered by many cloud platforms (such as AWS, Azure, and GCP). These cloud shells are often a packaged unified environment to use CLI and/or scripting modules hosted as a container in the cloud environment.
Como o Vigly audita a técnica Cloud API automaticamente na sua pipeline
O Vigly cruza sinais de SAST, modelagem de ameaças, regras de negócio e evidências do repositório para priorizar riscos reais antes que eles cheguem à produção.
