AWS SQS Queue Purge

Identifies when an AWS Simple Queue Service (SQS) queue is purged. Purging an SQS queue permanently deletes all messages currently in the queue. Adversaries may use this action to disrupt application workflows, destroy operational data, or impair monitoring and alerting by removing messages that contain evidence of malicious activity.

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 EventBridge Rule Disabled or Deleted

Identifies when an Amazon EventBridge rule is disabled or deleted. EventBridge rules are commonly used to automate operational workflows and security-relevant routing (for example, forwarding events to Lambda, SNS/SQS, or security tooling). Disabling or deleting a rule can break critical integrations, suppress detections, and reduce visibility. Adversaries may intentionally impair EventBridge rules to disrupt monitoring, delay response, or hide follow-on actions.

AWS WAF Rule or Rule Group Deletion

Identifies the deletion of an AWS Web Application Firewall (WAF) rule or rule group. WAF rules and rule groups enforce critical protections for web applications by filtering malicious HTTP requests, blocking known attack patterns, and enforcing access controls. Deleting these rules—even briefly—can expose applications to SQL injection, cross-site scripting, credential-stuffing bots, or targeted exploitation. Adversaries who have gained sufficient permissions may remove WAF protections as part of
