Identifies when an administrator role is assigned to a user account in Google Workspace. Security teams can monitor for the malicious or accidental assignment of administrator privileges to prevent unauthorized access to data. The rule specifically looks for `USER_RESOURCE_UPDATE_PERMISSIONS` events with `ASSIGN_ROLE` as the product event type and `DELEGATED_ADMIN_SETTINGS` in the security result category details. It also calculates a higher risk score if the assigned role is `_SEED_ADMIN_ROLE`.
This rule detects when a GuardDuty Detector's publishing destination has been deleted. GuardDuty is an AWS threat detection service that continuously monitors for malicious activity and unauthorized behavior to protect AWS accounts and workloads. Deleting its publishing destination prevents GuardDuty from exporting its findings, effectively impairing the organization's ability to detect and respond to security incidents. This action could be performed by an attacker attempting to hide their activities or by an insider aiming to reduce security visibility.
This rule detects AWS IAM activities associated with the S3 Browser utility. Specifically, it looks for attempts to create new users (`CreateUser`), create login profiles (`CreateLoginProfile`), create access keys (`CreateAccessKey`), or put user policies (`PutUserPolicy`) within AWS IAM. The detection is triggered when these actions are performed and the HTTP user agent string in the CloudTrail log indicates the use of 'S3 Browser'. This combination of actions and user agent suggests potential account manipulation for persistence or privilege escalation within an AWS environment.
This rule detects when an AWS region is enabled or disabled. Adversaries may enable new regions to create resources in an unmonitored environment or disable regions to disrupt services or evade detection. This activity is captured through AWS CloudTrail events for 'EnableRegion' or 'DisableRegion'.
Detects when a user creates or updates a login profile for another user in AWS IAM and then the newly created/modified user logs in from the same IP address. This behavior can indicate privilege escalation where an attacker gains access to an existing user's credentials, creates a new login profile or modifies an existing one for another user, and then uses that new profile to log in, potentially escalating their privileges or maintaining persistence.
This rule detects when Security Command Center services are disabled in Google Cloud Platform (GCP). Disabling Security Command Center can impair an organization's ability to detect security threats and vulnerabilities, making it a critical security event. The rule specifically looks for 'RESOURCE_WRITTEN' events in GCP Cloud Audit logs where the product event type indicates an update to Security Command Center settings, the target application is 'securitycenter.googleapis.com', and the 'service_enablement_state' label is set to 'DISABLED'.
This rule detects when an Okta end-user reports suspicious activity on their account. This could indicate that the user's account has been compromised or is being targeted by an attacker. The rule specifically looks for the 'user.account.report_suspicious_activity_by_enduser' event type in Okta logs. The risk score is increased if the suspicious activity event type is related to an MFA enrollment notification being sent, suggesting a potential attempt to enroll an unauthorized MFA device.
This rule detects administrative actions related to AWS SAML Identity Providers. Specifically, it triggers when a SAML provider is created, updated, or deleted within an AWS environment. Monitoring these events is crucial as SAML providers are used for federated access, and unauthorized changes could indicate attempts at persistence, privilege escalation, or defense evasion by manipulating authentication mechanisms.
This rule detects the creation of a new API token within the Okta identity platform. API tokens can be used for programmatic access to Okta and, if compromised, can lead to unauthorized access, persistence, or privilege escalation. The rule specifically looks for 'system.api_token.create' events with a successful 'ALLOW' action.
This rule detects when the AWS IAM AdministratorAccess policy is attached to a user, group, or role. This action grants full administrative privileges and can be used by an attacker for privilege escalation, persistence, or to establish initial access within an AWS environment. The rule specifically looks for CloudTrail events indicating policy attachment actions (AttachUserPolicy, AttachGroupPolicy, AttachRolePolicy) where the target resource is the predefined 'AdministratorAccess' policy and the action was allowed.
This rule detects the creation of new applications within Microsoft Entra ID (formerly Azure AD). While application creation is a legitimate administrative activity, it does not occur frequently. Monitoring this event can help identify unauthorized or suspicious application registrations that could be used for persistence, privilege escalation, or other malicious activities within the cloud environment.
This rule detects when a user is assigned 'Super user' privileges within the OneLogin SSO system. It specifically looks for events where the event type is 'USER_CHANGE_PERMISSIONS', the product is 'ONELOGIN_SSO', the vendor is 'ONELOGIN', the product event type indicates a permission grant (code 72), and the target resource name is 'Super user'. This indicates a significant privilege escalation within the identity provider.
Detects when an Amazon Simple Email Service (SES) configuration is modified, which could indicate an attacker attempting to propagate phishing email campaigns. This includes the creation, deletion, or verification of email identities and domains, as well as enabling sending for accounts or configuration sets.
This rule detects when a permission on a pre-defined watchlist is applied to an Entra ID application. It specifically looks for 'Update application.' events in Office 365 logs where the 'NewValue_EntitlementId-' or 'OldValue_EntitlementId-' labels indicate a change in application permissions. The rule leverages a watchlist named 'msgraph_watchlist_permissions' to identify sensitive or suspicious permission changes.
Detects when an excessive number of permissions are assigned to an Entra ID application within a short time window, calculated as a percentage increase from existing permissions. This could indicate a "greedy permission grab" by an attacker attempting to escalate privileges or gain broader access within the Entra ID environment. The rule specifically looks for updates to application permissions where the percentage increase of new permissions over old permissions exceeds a 70% threshold.
Detects when a user removes an authentication factor or OTP device within OneLogin. This action can weaken security by removing a layer of multi-factor authentication, potentially making the account more vulnerable to compromise.
Detects when an excessive number of permissions are assigned to an Entra ID application within a time window, potentially indicating a greedy permission grab, as a numeric value comparing old permissions to new permissions
Detects when an excessive number of permissions are assigned to an Entra ID application within a time window, potentially indicating a greedy permission grab, as a percentage from old permissions to new permissions
Identifies when a Marketplace app is added in a Google Workspace organization. Installing certain apps may increase the organization's risk of data exfiltration/leakage and increase its attack surface.
Detects when a new API token is created.
Detects when a user assumes multiple user accounts.
