Deprecated - AWS RDS Instance Creation

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

Azure Kubernetes Services (AKS) Kubernetes Pods Deleted

Identifies the deletion of Azure Kubernetes Pods. Adversaries may delete a Kubernetes pod to disrupt the normal behavior of the environment.

Rapid7 Threat Command CVEs Correlation

This rule is triggered when CVEs collected from the Rapid7 Threat Command Integration have a match against vulnerabilities that were found in the customer environment.

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.

Deprecated - AWS EC2 VM Export Failure

Identifies an attempt to export an AWS EC2 instance. A virtual machine (VM) export may indicate an attempt to extract or exfiltrate information.

Azure Blob Storage Container Access Level Modified

Identifies changes to container access levels in Azure. Anonymous public read access to containers and blobs in Azure is a way to share data broadly, but can present a security risk if access to sensitive data is not managed judiciously.

Deprecated - AWS EC2 Snapshot Activity

An attempt was made to modify AWS EC2 snapshot attributes. Snapshots are sometimes shared by threat actors in order to exfiltrate bulk data from an EC2 fleet. If the permissions were modified, verify the snapshot was not shared with an unauthorized or unexpected AWS account.

Deprecated - AWS Redshift Cluster Creation

Identifies the creation of an Amazon Redshift cluster. Unexpected creation of this cluster by a non-administrative user may indicate a permission or role issue with current users. If unexpected, the resource may not properly be configured and could introduce security vulnerabilities.

AWS EC2 Export Task

Identifies successful export tasks of EC2 instances via the APIs CreateInstanceExportTask, ExportImage, or CreateStoreImageTask. These exports can be used by administrators for legitimate VM migration or backup workflows however, an attacker with access to an EC2 instance or AWS credentials can export a VM or its image and then transfer it off-account for exfiltration of data.

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 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.

Entra ID Device with ROADtools Default OS Build (Entity Analytics)

Identifies the first occurrence of a Microsoft Entra ID device, surfaced through the Entra ID Entity Analytics device inventory, whose host name follows the default "DESKTOP-" pattern and whose operating system build is `10.0.19041.928`. This combination is the default device profile that ROADtools (roadtx) uses when registering a device, and the OS build typically differs from the patched OS versions of legitimate hosts in the environment. Adversaries register rogue devices in Entra ID to acqui

Entra ID Phishing Kit Default OS Build (Entity Analytics)

Identifies the first occurrence of a Microsoft Entra ID device, surfaced through the Entra ID Entity Analytics device inventory, whose host name follows the default "DESKTOP-" pattern and whose operating system build is "10.0.19045.2006". This is the frozen default device profile observed when adversary-in-the-middle (AiTM) phishing kits such as Tycoon2FA and Kali365 register Azure AD-joined devices after capturing a victim session, in order to acquire a Primary Refresh Token (PRT) and establish

AWS Route 53 Domain Transfer Lock Disabled

Identifies when the transfer lock on an AWS Route 53 domain is disabled. The transfer lock protects domains from being moved to another registrar or AWS account without authorization. Disabling this lock removes an important safeguard against domain hijacking. Adversaries who gain access to domain-management permissions may disable the lock as a precursor to unauthorized domain transfer, takeover, or service disruption.

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 Cognito Unauthenticated Identity Pool Credentials Issued

Identifies AWS CloudTrail data events where an unauthenticated identity successfully retrieves temporary AWS credentials from a Cognito Identity Pool via GetCredentialsForIdentity. Cognito Identity Pools can be configured to allow unauthenticated (guest) access, intended for scenarios like anonymous app analytics, but a pool that grants those anonymous identities meaningful IAM permissions becomes a public, unauthenticated path to real AWS credentials. Adversaries who discover an identity pool I

Azure Virtual Machine Configuration Modified

Identifies a successful write to an Azure virtual machine resource ("MICROSOFT.COMPUTE/VIRTUALMACHINES/WRITE"). This operation is the parent action behind VM userData injection, where an adversary with VM contributor rights writes a base64 startup payload into the VM "userData" field that executes on the next reboot (a control-plane persistence technique requiring no guest access). The Azure activity log does not record the "userData" value or which property changed, so this behavior is indistin

AWS Route 53 Domain Transferred to Another Account

Identifies when an AWS Route 53 domain is transferred to another AWS account. Transferring a domain changes administrative control of the DNS namespace, enabling the receiving account to modify DNS records, route traffic, request certificates, and potentially hijack operational workloads. Adversaries who gain access to privileged IAM users or long-lived credentials may leverage domain transfers to establish persistence, redirect traffic, conduct phishing, or stage infrastructure for broader atta

AWS S3 Unauthenticated Bucket Access by Rare Source

Identifies AWS CloudTrail events where an unauthenticated source is attempting to access an S3 bucket. This activity may indicate a misconfigured S3 bucket policy that allows public access to the bucket, potentially exposing sensitive data to unauthorized users. Adversaries can specify --no-sign-request in the AWS CLI to retrieve objects from an S3 bucket without authentication. This is a New Terms rule, which means it will trigger for each unique combination of the source.address and targeted b
