Description

Identifies when access to an Amazon Bedrock foundation model is enabled at the account level, either by granting a foundation-model entitlement, submitting a use case for model access, or creating a foundation-model agreement (accepting the EULA). These account-level "model access" actions unlock a foundation model so that it can subsequently be invoked. Adversaries or a compromised principal may enable model access to abuse expensive models (LLMjacking), to establish a durable ability to invoke models within the account, or to bypass organizational controls. This activity is distinct from changes to a resource-based model invocation policy and is identified by the Bedrock control-plane API calls that grant model entitlements and agreements.

Its licence does not clear it for publishing here

Sunturai publishes a detection's own text where the licence it arrived under has been reviewed and permits it, and Elastic License 2.0 has not. The query as its source wrote it, its canonical form and the hash that pins this revision are in the workspace record.

Known benign triggers

  • Cloud administrators and machine-learning teams routinely enable model access, submit use cases, and accept model end-user license agreements (EULAs) during account onboarding or when adopting a new foundation model. Verify that the principal, source IP, and user agent are expected and that the change aligns with a known onboarding or provisioning activity before escalating. If this activity is expected and authorized for specific principals, consider adding exceptions for those users or roles.
