Detects the creation of an AWS Bedrock AgentCore resource (code interpreter, agent runtime, browser, or harness) with an IAM execution role attached. When an attacker with iam:PassRole permission creates an AgentCore resource and attaches a privileged role, subsequent invocations inside that resource execute as the attached role — enabling privilege escalation to roles that trust bedrock-agentcore.amazonaws.com.

Detects deletion, weakening, or version management of AWS Bedrock guardrails via the DeleteGuardrail, UpdateGuardrail, DeleteEnforcedGuardrailConfiguration, or PutEnforcedGuardrailConfiguration APIs. Bedrock guardrails enforce content, topic, word, and sensitive-information policies on model invocations. Deleting a guardrail, loosening its policies, removing or overwriting the organization-enforced guardrail configuration, or creating a new version to enforce a weakened configuration allows an adversary to bypass these protections — the cloud control-plane equivalent of disabling a security tool. This activity should be validated against approved change management and the responsible identity.
