What it detects

This rule detects AWS CloudTrail activity from the specific Boto3 1.42.73 build running on Kali Linux that TeamPCP used to enumerate IAM EC2 Lambda and Secrets Manager resources after stealing credentials. The pairing of this SDK version with a Kali offensive distribution user agent is a strong indicator of hands-on-keyboard cloud reconnaissance with stolen keys.
