Detects a sequence of events on a single device involving a remote MSI installation followed by PowerShell-based process elevation and administrative checks using fltmc.exe. This pattern is indicative of an attacker attempting to deploy malicious packages remotely and escalate privileges within the environment.

Flags Global Administrator / Privileged Role Administrator role grants occurring within one hour of a password/MFA reset or TAP issuance on the same account — the terminal step of a completed helpdesk-vishing takeover.
KQL Query
Detects potential exploitation of Active Directory Certificate Services (AD CS) misconfigurations (specifically ESC1, involving client-auth EKU and enrollee-supplies-subject). The rule correlates certificate issuance events (4886, 4887, 4888) involving sensitive templates or suspicious subject alternative name (SAN) mismatches with subsequent Kerberos PKINIT authentication (4768) events using the issued certificate.
Detects a SYSTEM-level dllhost.exe process, associated with specific COM object instantiation (CLSID {135fd325-45b7-4c30-89f8-4386961669f0}), loading a DLL from the C:\ProgramData\ directory. This behavior is indicative of an attacker-planted DLL being unmarshaled through a crafted OBJREF, effectively bypassing security controls like EOAC_NO_CUSTOM_MARSHAL.
Detects the loading or service registration of known vulnerable or malicious signed drivers commonly used in Bring Your Own Vulnerable Driver (BYOVD) attacks. These drivers are leveraged by adversaries to gain kernel-level privileges, bypass security controls, and terminate endpoint protection agents.
Detects execution of auto.exe (associated with AvisLoader) combined with a specific registry-based UAC bypass technique using the ICMLuaUtil COM elevation moniker (CLSID 3E5FC7F9-9A51-4367-9063-A120244FBEC7). This pattern is characteristic of UACME method 41 to achieve privilege escalation.

Detects the loading of a known malicious 136KB browser injection helper DLL (SHA256: 75018b06c7105a1dca391805d17b402aed35ebd515b92d461236eafbd606cb40) into Google Chrome or Microsoft Edge processes. The rule further correlates this activity with command line arguments indicative of abusing the browser's elevation service, which is a technique often used for process injection or local privilege escalation.
Detects a UAC bypass sequence associated with the ChainScript/Rapuncel loader, where a process invokes an 'elevation:Administrator!new' COM moniker (such as CMSTPLUA or ICMLuaUtil) followed by the execution or hollowed-out spawning of 'ServiceModelReg.exe' to achieve elevated privileges.
Detects attempts by AI agent code-interpreter or sandbox processes to break out of their containerized environment. The rule monitors for the execution of common container escape techniques, such as namespace manipulation (nsenter, unshare), mounting host filesystems, accessing sensitive host devices like /dev/kmsg or /dev/mem, or referencing host-level paths from within an isolated AI agent execution process.
Detects a specific pattern of Windows API calls consistent with PIVOTPIPE C2 activity, involving process token impersonation (OpenProcessToken, DuplicateTokenEx, ImpersonateLoggedOnUser, or SetThreadToken) followed by a RevertToSelf call. The rule correlates these events within a single process, identifies artifacts related to PIVOTPIPE loader/payloads, and ensures the sequence completes within a short time window.
Detects the creation or execution of a scheduled task named 'CreateObjectTask' via schtasks or PowerShell, which is associated with spawning 'dllhost.exe' as a child process under high-privileged parent processes (svchost, taskeng, or schtasks). This behavior is indicative of potential COM hijacking or privilege escalation techniques leveraging system tasks.
Detects a low-privileged account manually triggering the 'CreateObjectTask' scheduled task, which is a known technique to force the 'Shell Create Object Handler' (dllhost.exe) to start under the SYSTEM context. This behavior is often associated with pre-exploitation steps for privilege escalation vulnerabilities, specifically those involving OBJREF marshaling targeting specific COM objects.
Detects the loading of the Alinubx.sys (aka CcProtect.sys) kernel driver, often dropped as nvfsflt64.sys or registered as NvFsFilter, followed by a rapid, simultaneous termination of security product processes. This activity is indicative of a BYOVD (Bring Your Own Vulnerable Driver) attack chain where kernel-mode primitives are used to terminate EDR/AV processes.
Detects the execution of command interpreters or scripting engines spawned by the ManageEngine ADSelfService Plus GINA client process (typically present at the Windows logon screen). This activity is highly suspicious as it indicates potential command injection or abuse of a pre-authentication component running at SYSTEM privileges.
Detects the exploitation of the CMSTPLUA COM-object (CLSID 3E5FC7F9-9A51-4367-9063-A120244FBEC7) to bypass User Account Control (UAC). The rule monitors for PowerShell processes instantiating this object, followed by the execution of a hidden-window PowerShell process, bypassing the consent.exe UAC prompt.
Detects a specific sequence of Android Debug Bridge (ADB) commands typical of malicious Android agents, specifically those running with elevated privileges (UID 2000/shell/root). The rule identifies combinations of permission grants, battery optimization bypasses, and package tampering (disabling or uninstalling) occurring within the same context.
Detects a specific sequence of Android Debug Bridge (ADB) commands typical of malicious Android agents, specifically those running with elevated privileges (UID 2000/shell/root). The rule identifies combinations of permission grants, battery optimization bypasses, and package tampering (disabling or uninstalling) occurring within the same context.
Detects a specific Android sandbox escape technique where a malicious app enables Accessibility Services and Developer Options/Wireless Debugging to initiate a self-pairing ADB connection over localhost. This bypasses typical app sandbox restrictions, allowing the execution of processes with the UID 2000 (shell) context.
