Detects instances of dllhost.exe running with elevated integrity (High or System) that were not spawned by the standard DCOM Server Process Launcher (svchost.exe). This behavior is characteristic of COM object hijacking or auto-elevation techniques used to bypass UAC.
Detects attempts to bypass User Account Control (UAC) by modifying specific registry keys (ms-settings or mscfile) used for shell execution. By hijacking these classes and adding a command, attackers can force a system-native, auto-elevating binary (like fodhelper.exe, eventvwr.exe, or computerdefaults.exe) to execute malicious code with high integrity.

Detects potential User Account Control (UAC) bypass attempts using the PowerShell 'Start-Process' cmdlet with the 'runAs' verb, which requests administrative privileges for a new process. The rule also includes a specific check for command-line artifacts associated with the 'wipe32' malware campaign, which utilizes this method for privilege escalation.
Detects attempts to bypass User Account Control (UAC) by invoking the CMSTPLUA COM interface (CLSID: {3E5FC7F9-9A51-4367-9063-A120244FBEC7}). This technique allows an attacker to execute processes with elevated privileges by leveraging the auto-elevation property of this COM object, often using the 'Elevation:Administrator!new' moniker.
Detects instances of dllhost.exe running with elevated integrity (High or System) that were not spawned by the standard DCOM Server Process Launcher (svchost.exe). This behavior is characteristic of COM object hijacking or auto-elevation techniques used to bypass UAC.
Detects creation of a new local user account and its addition to the local Administrators group, consistent with the plugin32.dll RDP backdoor module which hardcodes a username/password and adds the new account to the administrators group for persistent RDP access.
This rule detects the creation of the 'C:\Config.Msi' folder or files within it that have weak security descriptors (SDDL). This folder is frequently used by the Windows Installer service, and if insecure permissions are applied, an attacker can perform privilege escalation or perform DLL hijacking by placing malicious files within this directory.
Detects the JC-46 AsyncRAT technique chain where the malware opens winlogon.exe's process token, duplicates it into an impersonation token, calls ImpersonateLoggedOnUser, enables SE_DEBUG_NAME via AdjustTokenPrivileges to reach SYSTEM context, then uses CNG (NCryptOpenStorageProvider/NCryptOpenKey/NCryptDecrypt) and BCrypt AES-GCM (BCryptOpenAlgorithmProvider) APIs to unwrap Chromium v96+ App-Bound Encryption keys.

This rule detects instances of the 'su' utility being executed in a manner inconsistent with normal system administration patterns. By filtering out common, expected parent processes (such as login shells, terminal multiplexers, or established system services) and identifying 'su' command-line execution or shell commands attempting to invoke it, the rule flags potentially malicious privilege escalation attempts, such as those exploiting local vulnerabilities.
Detects the execution of 'sudo' or 'systemd-run' with specific flags often associated with automated credential processing or service creation for privilege escalation. The rule monitors for sudo commands using '-S' (read from stdin) and '-p' (custom prompt) flags, which are common in non-interactive scripts attempting to bypass or manipulate password prompts, and systemd-run commands using '--system' and '--no-ask-password', which can be used to run commands as root without interactive authentication.
Detects a suspicious sequence of events where a non-standard process writes to the Windows Installer TempPackages registry key, followed by the msiexec.exe process running as SYSTEM deleting the C:\Config.Msi folder. This behavior is indicative of potential privilege escalation or exploitation, such as CVE-2025-27727, where an attacker leverages msiexec's high-privilege context to perform unauthorized file operations.
Detects potential User Account Control (UAC) bypass attempts using the PowerShell 'Start-Process' cmdlet with the 'runAs' verb, which requests administrative privileges for a new process. The rule also includes a specific check for command-line artifacts associated with the 'wipe32' malware campaign, which utilizes this method for privilege escalation.

Detects Docker CLI execution attempting to bind mount sensitive host system directories (e.g., Windows, ProgramData) into a container. This technique is often used as a container escape vector to gain unauthorized access to host files and escalate privileges to SYSTEM.
Detects attempts to grant world-writable (0666) permissions to the /dev/kvm device node using chmod or setfacl, or unauthorized (non-root) accounts interacting directly with the device. Such configuration changes are associated with the Januscape (CVE-2026-53359) vulnerability, which allows local users to exploit a shadow MMU use-after-free in the kernel to escalate privileges to root or escape into the host from a virtualized environment.
Detects Python processes (python.exe or pythonw.exe) executed with a custom '--elevated' argument, which is indicative of Starland RAT attempting to perform UAC bypass or elevation.
