Detect unusual API call patterns in AWS CloudTrail logs using boto3,.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Detecting AWS CloudTrail Anomalies ## Overview AWS CloudTrail records API calls across AWS services. This skill covers querying CloudTrail events with boto3's `lookup_events` API, building statistical baselines of normal API activity, detecting anomalies such as unusual event sources, geographic anomalies, high-frequency API calls, and first-time API usage patterns that indicate compromised credentials or insider threats. ## When to Use - When investigating security incidents that require detecting aws cloudtrail anomalies - When building detection rules or threat hunting queries for this domain - When SOC analysts need structured procedures for this analysis type - When validating security monitoring coverage for related attack techniques ## Prerequisites - Python 3.9+ with `boto3` library - AWS credentials with CloudTrail read permissions (cloudtrail:LookupEvents) - Understanding of AWS IAM and common API patterns - CloudTrail enabled in target AWS account (management events at minimum) ## Steps ### Step 1: Query CloudTrail Events Use boto3 CloudTrail client's lookup_events to retrieve recent API activity with pagination. ### Step 2: Build Activity Baseline …

How to install
mdr add adriannoes/awesome-agentic-ai/detecting-aws-cloudtrail-anomalies@sha256:363865b0494e93aaThe line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
