This rule detects attempts to enumerate AWS IAM groups via the 'ListGroups' API call. It specifically looks for HTTP traffic directed to 'iam.amazonaws.com' with 'ListGroups' in the URI, indicating a potential reconnaissance activity against AWS Identity and Access Management.
This rule detects HTTP requests to the Google Cloud Asset Inventory API, specifically targeting the '/assets' endpoint. This activity could indicate an attempt to enumerate cloud resources within a Google Cloud Platform environment.
This rule detects attempts to enumerate AWS EC2 instances via the DescribeInstances API call. It specifically looks for HTTP traffic destined for 'ec2.amazonaws.com' with 'DescribeInstances' in the URI, indicating a potential reconnaissance activity against AWS EC2 infrastructure.
This rule detects the creation of a new cloud account (user) in Amazon Web Services (AWS) via the Identity and Access Management (IAM) API. It specifically looks for HTTP traffic to 'iam.amazonaws.com' with 'CreateUser' in the URI, indicating an attempt to create a new IAM user.
This rule detects HTTP POST requests to Amazon Web Services (AWS) endpoints that are associated with non-standard or less common cloud regions. Specifically, it looks for 'amazonaws.com' in the HTTP host and then checks the HTTP URI for region codes 'ap-east' (Asia Pacific - Hong Kong), 'me-south' (Middle East - Bahrain), or 'af-south' (Africa - Cape Town). The detection is triggered when a resource creation (indicated by HTTP POST) is attempted in one of these regions, which might be unusual for an organization primarily operating in other regions, potentially indicating unauthorized activity or misconfiguration.
This rule detects when Azure Monitor Diagnostic Settings are deleted. It specifically looks for HTTP DELETE requests to 'management.azure.com' with 'diagnosticSettings' in the URI. This activity could indicate an attacker attempting to evade detection by removing logging configurations.
This rule detects attempts to access secrets stored in Google Cloud Platform (GCP) Secret Manager via its API. It specifically looks for HTTP traffic directed to 'secretmanager.googleapis.com' with a URI path containing '/versions/' and ':access', indicating an attempt to access a specific secret version.
Detects successful device code flow sign-ins to the Microsoft Authentication Broker application targeting the Microsoft Graph resource, specifically when the sign-in does not originate from a trusted named location. This activity can indicate a device code phishing attempt where an attacker tricks a user into authenticating a malicious application.
Detects modification of hybrid identity federation configuration for authentication bypass
Detects addition of credentials to Azure service principals for persistence
Detects addition of email delegate permissions for mailbox access persistence
This rule detects suspicious application consent activity in Azure AD. It identifies instances where a user successfully grants consent to three or more applications within a one-hour window. This behavior can indicate an adversary attempting to gain access to resources by tricking users into consenting to malicious applications.
Detects when a single user principal name (UPN) performs two or more Azure AD admin role assignments within an hour. This could indicate an attempt to escalate privileges or establish persistence by assigning administrative roles to multiple accounts or to the same account multiple times.
This rule detects when a third-party cloud application is authorized to access a Google account. It specifically looks for HTTP traffic to 'accounts.google.com' with a URI containing 'oauth2/auth' and 'scope', indicating an OAuth 2.0 authorization request. A threshold is set to trigger an alert if this activity occurs 3 times within 60 seconds from the same source IP address.
This rule detects potential AWS CLI API command execution by monitoring HTTP traffic for connections to 'amazonaws.com' and the presence of 'Action=' in the URI. It uses a threshold of 30 occurrences within 10 seconds from a single source IP to reduce false positives, indicating a high volume of API calls typical of automated scripts or tools.
This rule detects attempts to query AWS CloudTrail logs for activity discovery. Specifically, it looks for HTTP traffic to 'cloudtrail.amazonaws.com' with the URI containing 'LookupEvents'. This activity could indicate an attacker attempting to understand the environment or their own actions.
This rule detects attempts to modify an EC2 instance's attributes, specifically looking for the 'ModifyInstanceAttribute' API call to 'ec2.amazonaws.com'. This activity could indicate an attacker attempting to evade detection or alter the instance's configuration for malicious purposes.
This rule detects HTTP POST requests to cloud compute infrastructure management endpoints, specifically Amazon EC2, Google Cloud Compute, and Azure Management. The rule is triggered if 20 such requests are observed from a single source IP within 60 seconds, indicating potential automated activity to modify cloud infrastructure for evasion purposes.
This rule monitors successful operations related to Azure Traffic Manager within Azure Activity logs. It summarizes the count of such operations by the caller and time, ordered by the most recent activity. This can be used to track administrative actions or changes made to Traffic Manager configurations.
Detects the successful creation or update of an Azure API Management Service. This activity could indicate legitimate administrative actions or, if unexpected, potential unauthorized access or privilege escalation within the Azure environment. Monitoring these events can help identify suspicious configuration changes or resource provisioning by malicious actors.
This rule detects when an AWS IAM role is assumed, which can be a legitimate activity for temporary elevated access within an AWS environment. The detection is based on HTTP traffic to 'sts.amazonaws.com' with 'AssumeRole' in the URI, indicating a request to the AWS Security Token Service to assume an IAM role. This activity is often associated with privilege escalation techniques.
