Beyond valid credentials: How exposed AWS keys are tested for Amazon Bedrock access

Attackers test exposed AWS credentials to verify access to Amazon Bedrock by employing validation patterns specific to large language models (LLMs). The research details how threat actors probe stolen credentials to confirm whether they can interact with Bedrock services before attempting to extract data or incur costs.

Why it matters: Organizations using AWS and Bedrock must audit credential exposure, monitor for unauthorized application programming interface (API) calls, and implement credential rotation procedures, as exposed keys enable direct LLM service abuse and potential data exfiltration.
