Deprecated - AWS RDS Instance Creation

Identifies the creation of an Amazon Relational Database Service (RDS) Aurora database instance.

Deprecated - AWS RDS Instance/Cluster Stoppage

Identifies that an Amazon Relational Database Service (RDS) cluster or instance has been stopped.

Deprecated - AWS RDS Cluster Creation

Identifies the creation of a new Amazon Relational Database Service (RDS) Aurora DB cluster or global database spread across multiple regions.

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.

Deprecated - AWS RDS Security Group Creation

Identifies the creation of an Amazon Relational Database Service (RDS) Security group. Modern RDS deployments run in a VPC and use standard EC2 security groups instead. This rule should be retained only for historical log analysis on legacy CloudTrail data. We recommend relying on "AWS EC2 Security Group Configuration Change" rule for network-control changes impacting RDS in VPC-based deployments.

Deprecated - AWS RDS Security Group Deletion

Identifies the deletion of an Amazon Relational Database Service (RDS) Security group. Modern RDS deployments run in a VPC and use standard EC2 security groups instead. This rule should be retained only for historical log analysis on legacy CloudTrail data. We recommend relying on "AWS EC2 Security Group Configuration Change" rule for network-control changes impacting RDS in VPC-based deployments.

AWS RDS DB Snapshot Shared with Another Account

Identifies when an AWS RDS DB snapshot is shared with another AWS account or made public. DB snapshots contain complete backups of database instances, including schemas, table data, and sensitive application content. When shared externally, snapshots can be restored in another AWS environment, enabling unauthorized access, offline analysis, or data exfiltration. Adversaries who obtain valid credentials or exploit misconfigurations may modify snapshot attributes to grant access to accounts they c

AWS RDS DB Instance Restored

Identifies the restoration of an AWS RDS database instance from a snapshot or S3 backup. Adversaries with access to valid credentials may restore copies of existing databases to bypass logging and monitoring controls or to exfiltrate sensitive data from a duplicated environment. This rule detects successful restoration operations using "RestoreDBInstanceFromDBSnapshot" or "RestoreDBInstanceFromS3", which may indicate unauthorized data access or post-compromise defense evasion.

AWS RDS Snapshot Deleted

Identifies the deletion of an AWS RDS DB snapshot or configuration changes that effectively remove backup coverage for a DB instance. RDS snapshots contain full backups of database instances, and disabling automated backups by setting "backupRetentionPeriod=0" has a similar impact by preventing future restore points. Adversaries with the appropriate permissions may delete snapshots or disable backups to inhibit recovery, destroy forensic evidence, or prepare for follow-on destructive actions suc

AWS RDS DB Instance or Cluster Password Modified

Identifies the modification of the master password for an AWS RDS DB instance or cluster. Changing the master password is a legitimate recovery action when access is lost, but adversaries with sufficient permissions may modify it to regain access, establish persistence, bypass existing controls, or escalate privileges within a compromised environment. Because RDS does not expose the password in API responses, this operation can meaningfully alter access pathways to sensitive data stores.

AWS EC2 LOLBin Execution via SSM SendCommand

Identifies the execution of Living Off the Land Binaries (LOLBins) or GTFOBins on EC2 instances via AWS Systems Manager (SSM) `SendCommand` API. This detection correlates AWS CloudTrail `SendCommand` events with endpoint process execution by matching SSM command IDs. While AWS redacts command parameters in CloudTrail logs, this correlation technique reveals the actual commands executed on EC2 instances. Adversaries may abuse SSM to execute malicious commands remotely without requiring SSH or RDP

AWS RDS DB Instance or Cluster Deleted

Identifies the deletion of an Amazon RDS DB instance, Aurora cluster, or global database cluster. Deleting these resources permanently destroys stored data and can cause major service disruption. Adversaries with sufficient permissions may delete RDS resources to impede recovery, destroy evidence, or inflict operational impact on the environment.

AWS RDS DB Instance or Cluster Deletion Protection Disabled

Identifies the modification of an AWS RDS DB instance or cluster to disable the deletionProtection feature. Deletion protection prevents accidental or unauthorized deletion of RDS resources. Adversaries with sufficient permissions may disable this protection as a precursor to destructive actions, including the deletion of databases containing sensitive or business-critical data. This rule alerts when deletionProtection is explicitly set to false on an RDS DB instance or cluster.

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 RDS Snapshot Export

Identifies the export of a DB snapshot or DB cluster data to Amazon S3. Snapshot exports can be used for analytics or migration workflows, but adversaries may abuse them to exfiltrate sensitive data outside of RDS-managed storage. Exporting a snapshot creates a portable copy of the database contents, which, if performed without authorization, can indicate data theft, staging for exfiltration, or operator misconfiguration that exposes regulated information.

AWS RDS DB Instance Made Public

Identifies the creation or modification of an Amazon RDS DB instance or cluster where the "publiclyAccessible" attribute is set to "true". Publicly accessible RDS instances expose a network endpoint on the public internet, which may allow unauthorized access if combined with overly permissive security groups, weak authentication, or misconfigured IAM policies. Adversaries may enable public access on an existing instance, or create a new publicly accessible instance, to establish persistence, mov

AWS RDS DB Snapshot Created

Identifies when an AWS RDS DB Snapshot is created. This can be used to evade defenses by allowing an attacker to bypass access controls or cover their tracks by reverting an instance to a previous state. This is a [building block rule](https://www.elastic.co/guide/en/security/current/building-block-rule.html) and does not generate alerts on its own. It is meant to be used for correlation with other rules to detect suspicious activity. To generate alerts, create a rule that uses this signal as a

AWS SSM `SendCommand` with Run Shell Command Parameters

Identifies the use of the AWS Systems Manager (SSM) `SendCommand` API with the either `AWS-RunShellScript` or `AWS-RunPowerShellScript` parameters. The `SendCommand` API call allows users to execute commands on EC2 instances using the SSM service. Adversaries may use this technique to execute commands on EC2 instances without the need for SSH or RDP access. This behavior may indicate an adversary attempting to execute commands on an EC2 instance for malicious purposes. This is a [New Terms](http

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

Insecure AWS EC2 VPC Security Group Ingress Rule Added

Identifies when a specified inbound (ingress) rule is added or adjusted for a VPC security group in AWS EC2. This rule detects when a security group rule is added that allows traffic from any IP address or from a specific IP address to common remote access ports, such as 22 (SSH) or 3389 (RDP). Adversaries may add these rules to allow remote access to VPC instances from any location, increasing the attack surface and potentially exposing the instances to unauthorized access.
