Resource Hijacking: Cloud Service Hijacking
5 rules across 2 sources.
From MITRE ATT&CK 19.2
Adversaries may leverage compromised software-as-a-service (SaaS) applications to complete resource-intensive tasks, which may impact hosted service availability.
For example, adversaries may leverage email and messaging services, such as AWS Simple Email Service (SES), AWS Simple Notification Service (SNS), SendGrid, and Twilio, in order to send large quantities of spam / Phishing emails and SMS messages. Alternatively, they may engage in LLMJacking by leveraging reverse proxies to hijack the power of cloud-hosted AI models.
In some cases, adversaries may leverage services that the victim is already using. In others, particularly when the service is part of a larger cloud platform, they may first enable the service. Leveraging SaaS applications may cause the victim to incur significant financial costs, use up service quotas, and otherwise impact availability.

Detection Strategy for Cloud Service Hijacking via SaaS Abuse
SaaS Analytic 0417
Adversary gains access to cloud-hosted services such as AWS SES, SNS, or OpenAI API, enables or modifies usage policies, and initiates resource-intensive actions (e.g., mass email/SMS or LLM queries), often from unauthorized regions or under anomalous identity conditions.
