Detects the addition of a federated identity credential to an Azure AD / Entra ID application. Adversaries may use this technique to establish persistent, secretless access to an application's service principal by configuring trust with an external OIDC issuer under their control (e.g., a malicious GitHub repository or personal OIDC provider).
Detects 'ec2:RunInstances' API calls occurring in AWS regions that are not part of the organization's approved allow-list. This behavior can be indicative of malicious infrastructure staging, such as deploying assets for unauthorized cryptomining or establishing pivot points in regions that are infrequently monitored.

This rule detects modifications to AWS IAM policies (PutUserPolicy, PutRolePolicy, PutGroupPolicy, AttachUserPolicy, AttachRolePolicy, or CreatePolicyVersion) that result in a policy granting administrative '*' access to both Actions and Resources. This pattern is commonly used by adversaries for persistence and privilege escalation after initial IAM credential compromise.
Detects a privilege escalation sequence where a principal uses 'PassRole' to attach an IAM role to a newly created compute resource (Lambda, EC2, or CloudFormation stack), followed shortly by that compute resource performing privileged API calls. This behavior indicates a potential attempt to gain unauthorized elevated permissions by executing actions from an over-privileged service identity.

This behavior indicates a potential attempt to gain unauthorized elevated permissions by executing actions from an over-privileged service identity.
Detects suspicious modifications to AWS Organization structure, specifically the moving of accounts out of protected organizational units (e.g., security, quarantine, guardrail), accounts leaving the organization, or the detachment of policies, which may indicate an attempt to evade security controls or organizational guardrails.
This rule detects modifications to AWS EC2 Snapshot or AMI (Image) attributes that result in the resource becoming publicly accessible ('all') or shared with an unapproved AWS account ID. Such activities are often precursors to data exfiltration or unauthorized access to sensitive disk images.
This rule detects a correlation between a successful non-interactive authentication event (e.g., token-based sign-in) and a subsequent device registration event performed by the same user identity within a short time window. This sequence is a known pattern for attackers seeking to register an adversary-controlled device against a compromised account to establish durable persistence and potentially bypass conditional access policies (PRT persistence).
Detects successful authentication attempts using legacy (basic) protocols that do not enforce modern Conditional Access policies (e.g., MFA, device compliance). The rule specifically flags these events if the originating IP address or geographic location is not observed in historical sign-in activity for the specific user, which may indicate account compromise via credential theft.
