The detection rule titled 'ASL AWS Credential Access GetPasswordData' monitors AWS accounts for the use of the GetPasswordData API, which is crucial for obtaining encrypted administrator passwords for Windows instances. These API calls are monitored using CloudTrail logs within Amazon Security Lake, and patterns of usage are analyzed to determine potential unauthorized access attempts. Specifically, the detection focuses on counting distinct instance IDs accessed through these calls, which may indicate an attacker's intention of gaining administrative access to AWS infrastructure. If such activity is confirmed, it poses a significant risk since attackers could gain full control over the compromised instances, leading to further exploitations within the AWS environment. The rule incorporates several analytics and filtering functions to maximize detection effectiveness while allowing for further investigation into suspicious user activities and associated risk events.
