AWS DynamoDB Table Exported to S3

Identifies when an AWS DynamoDB table is exported to S3. Adversaries may use the ExportTableToPointInTime operation to collect sensitive information or exfiltrate data from DynamoDB tables. This rule detects unusual user activity by monitoring for the ExportTableToPointInTime action in CloudTrail logs. This is a New Terms rule that only flags when this behavior is observed by a user or role for the first time.

AWS DynamoDB Scan by Unusual User

Identifies when an AWS DynamoDB table is scanned by a user who does not typically perform this action. Adversaries may use the Scan operation to collect sensitive information or exfiltrate data from DynamoDB tables. This rule detects unusual user activity by monitoring for the Scan action in CloudTrail logs. This is a New Terms rule that only flags when this behavior is observed by a user or role for the first time.

AWS Discovery API Calls via CLI from a Single Resource

Detects when a single AWS resource is running multiple read-only, discovery API calls in a 10-second window. This behavior could indicate an actor attempting to discover the AWS infrastructure using compromised credentials or a compromised instance. Adversaries may use this information to identify potential targets for further exploitation or to gain a better understanding of the target's infrastructure.

AWS Lambda Event Source Mapping Creation

Identifies the creation of an AWS Lambda event source mapping, which connects an event source such as an Amazon SQS queue, an Amazon Kinesis or DynamoDB stream, an Amazon MSK or self-managed Apache Kafka topic, or an Amazon MQ broker to a Lambda function so the function is automatically invoked when new records arrive. Adversaries with "lambda:CreateEventSourceMapping" permissions can abuse this to establish stealthy, event-driven persistence and execution, or to continuously siphon records from

AWS Backup Recovery Point Deleted

Identifies deletion of an AWS Backup recovery point via DeleteRecoveryPoint. A recovery point is a stored backup of a protected resource (EBS, RDS, DynamoDB, EFS, S3, and others). Deleting recovery points removes the ability to restore the associated data and is a core anti-recovery technique used in ransomware and data-destruction attacks to ensure victims cannot recover without paying or rebuilding. Routine lifecycle expirations are performed by the AWS Backup service itself; deletion by a non

AWS Backup Resource Enumeration via Long-Term Access Key

Detects enumeration of AWS Backup resources using long-term IAM access keys (AKIA* prefix). AWS Backup protects EC2 instances, EBS volumes, RDS databases, DynamoDB tables, EFS file systems, and S3 buckets. An adversary who obtains long-term access keys may enumerate backup vaults, backup plans, and protected resources as a precursor to ransomware. Identifying which resources have recent backups (indicating high-value data) and what vault access policies can be modified to delete or corrupt the b
