Detects when an AWS GuardDuty Detector's trusted IP lists or threat intelligence IP lists are deleted or disabled. This activity could indicate an adversary attempting to impair defensive capabilities to avoid detection.
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 when Amazon GuardDuty identifies a malicious or suspicious file being executed on an Amazon EC2 instance or a container workload. It specifically looks for GuardDuty findings with product event types 'MaliciousFile' or 'SuspiciousFile', excluding any sample findings.
This rule detects activity associated with the Tor network within an AWS account, as identified by AWS GuardDuty. It specifically looks for GuardDuty findings related to TorIPCaller, TorRelay, or TorClient, indicating potential use of Tor for anonymization or command and control.
This rule identifies outbound network connections where the destination IP address is geo-located to a specific country, which is configured as 'France' in this instance. It can be adapted to monitor traffic to any country of interest. The rule itself does not specify malicious behavior but flags network communication to a particular geographic region. This could be indicative of potential data exfiltration, command and control (C2) communication, or unauthorized access attempts if the country is considered high-risk or unusual for the organization's normal operations.
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 suspected password spraying attacks identified by Okta's ThreatInsight. It specifically looks for Okta security events categorized as 'Password Spray' and can additionally increase the risk score if the originating IP address is marked as suspicious by Okta ThreatInsight or if the login attempt originates from certain unauthorized geographies (Cuba, Iran, North Korea, Russia, Syria).
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 Command and Control (C2) activity identified by AWS GuardDuty across Amazon EC2, AWS Lambda, or Amazon EKS Runtimes. It specifically looks for GuardDuty findings with a product event type matching 'C&CActivity' and filters out sample findings. The rule aims to alert on suspicious communication patterns that indicate an adversary is controlling compromised resources within the AWS environment.
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.
