Detects unauthenticated execution of sensitive Grafana MCP tools (tools/call, grafana_api_request) by identifying session IDs that lack a corresponding authenticated handshake event. This behavior is indicative of potential session spoofing or abuse of the MCP protocol where an attacker attempts to interact with privileged tools without performing a valid authentication handshake.
Detects invocations of the 'grafana_api_request' tool that lack a preceding valid bearer-token authentication event for the same session. This indicates a potential scenario where a server or service account token is being used on behalf of an unauthenticated caller, bypassing normal authentication requirements for the Grafana API.
Detects instances where the Grafana MCP (Model Context Protocol) server's service account identity executes administrative tools (such as 'grafana_api_request') within a session that lacks a verified, prior authentication event (bearer token). This pattern suggests an adversary may be spoofing or hijacking a privileged service account session to perform unauthorized administrative actions.
This rule detects potentially unauthorized access to cloud resources or OAuth applications by identifying sign-ins or API calls originating from IP addresses or locations not previously observed for the user in the 30 days prior to a documented Coder registry compromise exposure window.

This pattern suggests an adversary may be spoofing or hijacking a privileged service account session to perform unauthorized administrative actions.
Detects sessions using shared Grafana service account tokens that perform both read-only and action-capable tool operations without confirmed prior authentication. This behavior is indicative of an unauthenticated or spoofed session leveraging a service account's excessive permissions, bypassing standard authentication flows.

Surfaces Silverfort-detected incidents excluding ImpossibleTravel (high FP rate from VPN and mobile users, better covered by XSIAM Analytics UEBA)
Detects Keycloak password reset attempts (UPDATE_PASSWORD) where the user has not performed the required preceding email verification (SEND_RESET_PASSWORD) and lacks a valid action-token. This pattern suggests an attempt to bypass the standard password reset workflow.
Detects anomalous, non-browser process activity interacting with Microsoft Teams APIs associated with the TWINLOOT threat campaign. The rules identify suspicious token retrieval requests and unauthorized authentication headers from processes that do not identify as legitimate browser or Teams application agents, indicating potential abuse of application access tokens and authentication flows.
This rule detects potentially unauthorized or suspicious administrative actions in an Azure environment following a login to specific AI-related applications (AI Gateway, LLM Proxy, or Model Router). It triggers when a user authenticates without applying Conditional Access policies or without Multi-Factor Authentication (MFA), followed immediately (within 30 minutes) by sensitive Azure administrative operations such as role assignments, Key Vault access, or VM write operations.

This Defender XDR query detects high-confidence attempts to export certificates with private keys using native Windows utilities, PowerShell, Mimikatz, AADInternals, Certipy, OpenSSL, and certificate-management tools.
Detects sign-in events using 'deviceCode' authentication or single-factor authentication via mobile/desktop clients where the device identifier has not been seen in the previous 30 days. This pattern can indicate an adversary using a new device to access an account, potentially utilizing stolen sessions or bypassing MFA.
