Detects when an AWS GuardDuty detector is disabled or suspended. This can indicate an adversary attempting to impair defenses to avoid detection.
Detects when an existing password policy is updated or deleted in an AWS account. This could indicate an adversary attempting to weaken password requirements to facilitate brute-force attacks or to remove obstacles for credential reuse.
This rule detects a specific privilege escalation scenario in AWS where a user creates a new access key for another user and then immediately uses that newly created access key from the same IP address to perform further actions. This behavior indicates an attempt to escalate privileges by leveraging a newly generated credential.
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 the creation, modification, copying, or moving of Windows shortcut (.lnk) files into sensitive user directories such as Desktop, Documents, and Start Menu folders. Adversaries often use .lnk files for persistence, execution, or to deliver malicious payloads, especially when placed in locations that are frequently accessed or automatically executed by the system or user.
This rule detects when AWS API Gateway keys are accessed with the 'includeValue' or 'includeValues' parameter set to 'true'. This indicates an attempt to retrieve the actual API key values, which could be a credential access attempt. The rule specifically looks for 'GetApiKey' and 'GetApiKeys' events in AWS CloudTrail logs where the request explicitly asks for the key's value.
Detects when an AWS CloudFront distribution is created or updated with an insecure SSL policy, specifically allowing TLSv1, SSLv3, TLSv1_2016, or TLSv1.1_2016. These protocols are considered insecure and can expose data to various attacks.
This rule detects when an EC2 instance makes a high number of API calls within a 5-minute window. The rule specifically looks for API calls originating from an assumed role associated with an EC2 instance, identified by a user ID matching the pattern `/i-.*$/`. A high number is defined as more than 7 distinct product event types within the specified timeframe. This behavior can indicate reconnaissance or other malicious activity from a compromised instance.
