This rule detects potential rogue SD-WAN peering attempts by correlating successful SSH public key authentication using 'vmanage-admin' from known malicious IPs with subsequent network activity on SD-WAN control plane ports (e.g., 48373 for OMP, 830 for NETCONF). It also flags logs containing references to an 'evil_tenant.csv' artifact, which is associated with adversary persistence or unauthorized configuration management in SD-WAN environments.
Detects the use of the RoadTx tool to perform a Resource Owner Password Credential (ROPC) grant against Microsoft Graph while bypassing MFA. This behavior leverages CVE-2025-0309 by abusing hidden Conditional Access exclusions for specific client IDs, resulting in an authentication token issued without an MFA claim.
Detects ROPC (Resource Owner Password Credentials) token requests to Microsoft Graph using specific client IDs associated with Microsoft To-Do or Intune Company Portal. This activity could indicate an attempt to bypass MFA via hidden Conditional Access policy exclusions, as described in CVE-2025-0309.
Detects a multi-stage attack pattern associated with the Qilin ransomware, beginning with suspicious VPN authentication (potential credential stuffing or bypass), moving through lateral movement attempts (SMB/RDP/WMI), and culminating in ransomware behaviors such as shadow copy deletion, mass file encryption, and ransom note creation.
This rule detects potentially malicious activity within Azure Automation by monitoring for the creation or modification of runbooks and jobs, combined with the presence of suspicious command-line or script patterns in job stream output, such as credential harvesting (e.g., Get-AutomationPSCredential) or execution of web-based payloads (e.g., IEX, Invoke-WebRequest).
Detects when a single user account performs 3 or more Privileged Identity Management (PIM) role activations within a 30-minute window. This behavior may indicate an attacker who has compromised a privileged account and is rapidly assuming multiple roles to perform lateral movement or privilege escalation.
Detects suspicious sequences of AWS CloudTrail API calls originating from non-console or non-service-account sources (CLI, curl, etc.). The rule flags scenarios where reconnaissance via 'GetCallerIdentity' is immediately followed by sensitive IAM modifications (CreateUser, CreateAccessKey) or privilege escalation attempts (AssumeRole), which may indicate the use of exfiltrated credentials.
Detects execution of AWS CLI subcommands used for credential or identity enumeration (e.g., sts get-caller-identity, iam get-user) when spawned from Amazon Q-related or development environment processes (Node.js/VS Code). This behavior is indicative of potential malicious activity involving a compromised MCP server configuration file (CVE-2026-12957).
Detects execution of Azure Automation runbook jobs by managed identities that have recently been assigned high-privilege roles (Owner, Contributor, or User Access Administrator). This behavior is indicative of potential privilege escalation or abuse of existing high-privilege identities to execute unauthorized automation tasks.
This rule detects potentially compromised accounts by correlating successful device code authentication events that exhibit anomalous characteristics (such as first-time usage, high/medium risk scores, or non-compliant/unmanaged device status) with highly sensitive Azure AD/Graph API administrative operations occurring within 30 minutes of the sign-in.
Detects execution of Azure Automation runbook jobs by managed identities that have recently been assigned high-privilege roles (Owner, Contributor, or User Access Administrator). This behavior is indicative of potential privilege escalation or abuse of existing high-privilege identities to execute unauthorized automation tasks.
This rule detects potentially compromised accounts by correlating successful device code authentication events that exhibit anomalous characteristics (such as first-time usage, high/medium risk scores, or non-compliant/unmanaged device status) with highly sensitive Azure AD/Graph API administrative operations occurring within 30 minutes of the sign-in.
Detects Entra ID guest (B2B) users performing a sign-in from a previously unseen IP address or country (observed over the last 30 days), followed within a 4-hour window by sensitive file operations in SharePoint, OneDrive, or Teams (e.g., file downloads, exports, or sensitivity label changes). This pattern is indicative of potential account takeover or unauthorized access to sensitive corporate data.
Detects Microsoft Entra ID (formerly Azure AD) sign-in logs where a single user account authenticates from two different countries within a 10-minute window, which is indicative of potential account compromise or credential sharing.
Flags Intune assignments to “All Devices” or “All Users,” which attackers may abuse for mass deployment.
This rule detects suspicious Azure AD sign-in activity where a user successfully signs in from multiple unusual cities within a 24-hour period. It specifically looks for sign-ins that are not from a trusted network and are not from a compliant device, aggregating successful sign-ins by UserPrincipalName and IpAddress, and flagging if there are 5 or more distinct cities.
Detects unauthorized, unauthenticated API activity targeting the ServiceNow 'related_list_edit' Scripted REST resource. The rule specifically alerts on requests originating from the 'Guest' account or where authentication requirements have been disabled, which are known indicators of exploitation.
This rule detects successful Azure AD authentication attempts originating from known hosting provider or VPS IP addresses, combined with anomalous behavior such as headless browser user agents, impossible travel, or high-risk sign-in flags. This pattern is indicative of Adversary-in-the-Middle (AiTM) phishing proxies like Evilginx or Bluekit, which attempt to bypass MFA by proxying the authentication process.
Detects anomalous activities targeting SaaS CRM applications (Salesforce, Microsoft Dynamics 365, HubSpot), including high-volume bulk exports, off-hours access, mass API queries for sensitive objects, and suspicious OAuth token grants.
Detects the registration of a new device or MFA authentication method in Microsoft Entra ID from an IP address geolocated to Morocco. This is a persistence tactic used by the Jingle Thief group (also tracked as Atlas Lion and STORM-0539).
Detects instances where a single authentication correlation ID is associated with multiple distinct IP addresses within a 10-minute window, followed by high-risk administrative or data-access actions within 30 minutes. This behavior is indicative of session hijacking or post-authentication account compromise, where an adversary uses stolen session tokens to perform unauthorized activities.
