The coverage focuses on suspicious model invocation patterns visible in Bedrock invocation logs and downstream SIEM telemetry: prompt injection keywords, hostile prompt sentiment, sensitive data in prompts, unusually large prompts, excessive output-token anomalies, cross-region inference mismatches, and high-risk filesystem or execution tool invocation through Claude workflows.

Detection Coverage

Defenders should enable Amazon Bedrock model invocation logging, route request and response metadata into their SIEM, and deploy the rules in this brief as a single monitoring package for Claude usage. Treat high-risk tool invocation and sensitive-data prompt exposure as higher-priority findings, especially when tied to human identities, unusual regions, or identities deviating from historical token baselines.

Recommendation

  • Enable AWS Bedrock model invocation logging and ingest Claude request/response metadata into Splunk or an equivalent SIEM.
  • Deploy the six public detection rules in this brief and tune thresholds for expected developer, red-team, and testing activity.
  • Investigate identities triggering multiple Bedrock Claude detections on the same day, especially combinations of prompt injection, sensitive data exposure, cross-region inference, and high-risk tool usage.
