AWS Discovery API Calls via CLI from a Single Resource

Detects when a single AWS resource is running multiple read-only, discovery API calls in a 10-second window. This behavior could indicate an actor attempting to discover the AWS infrastructure using compromised credentials or a compromised instance. Adversaries may use this information to identify potential targets for further exploitation or to gain a better understanding of the target's infrastructure.

Suspicious AWS S3 Connection via Script Interpreter

Detects when a script interpreter (osascript, Node.js, Python) with minimal arguments makes an outbound connection to AWS S3 or CloudFront domains. Threat actors have used S3 buckets for both command and control and data exfiltration. Script interpreters connecting to cloud storage should be investigated for potential malicious activity.
