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.
Detects potential credential harvesting or process memory manipulation against browser processes (Chrome or Edge). The rule monitors for unauthorized debugging activity initiated against browser processes (e.g., using flags like DEBUG_PROCESS or specific API calls) and the access of the App-Bound encryption provider symbol, which is often a target for attackers seeking to decrypt browser-stored secrets.
Detects a privilege escalation technique where an attacker with application management permissions adds a credential to the 'Office 365 Exchange Online' service principal (SP). The attacker then leverages the SP's 'Domain.ReadWrite.All' permission to add or modify a federated domain, allowing them to forge tokens for any hybrid user.
This rule detects the addition of specific suspicious executables to Windows Registry run keys. Adversaries use these keys to achieve persistence, ensuring that malicious programs execute automatically upon user logon.
Detects suspicious executions of 'nslookup.exe' and 'svchost.exe' when triggered by the Windows LockAppHost process. This pattern is indicative of potential process injection or masquerading attempts by malicious actors using legitimate system processes as proxies for unauthorized activity.
This rule detects the use of the LockAppHost process to execute suspicious commands associated with tampering with security configurations, including Windows Defender settings, service management (sc.exe), and task scheduling. Adversaries may abuse this process to bypass security controls, disable real-time monitoring, or maintain persistence.
Detects KATARU IoT malware samples embedding the DirtyFrag (CVE-2026-43284) Linux local privilege escalation exploit copied from public PoC code, as part of a chained LPE attempt targeting root shell spawning
This rule detects potential persistence attempts by monitoring for the execution and service installation commands of specific binaries: cplsupport.exe and wtass.exe. The rule triggers if these files are executed directly, invoked with specific command-line arguments (e.g., '--install'), or used in conjunction with the 'sc.exe' utility to create new services, which is a common technique for establishing persistence or privilege escalation.
Detects suspicious service installation patterns involving WmiPrvSE, common in lateral movement techniques.
Detects file creation, modification, or renaming in System32 by TieringEngineService.exe or MsMpEng.exe within a short time frame.
