Detects a sequence of events where a non-root user attempts to manipulate kernel components (specifically involving xfrm/esp modules via ip or modprobe) followed immediately by a sudo or su command, suggesting an attempt to load malicious kernel modules or exploit kernel vulnerabilities to escalate privileges.
This rule detects successful configuration modifications to diagnostic settings or storage services where the destination resource is identified as being outside of the organization's trusted subscriptions or expected storage naming conventions. This activity may indicate an adversary attempting to exfiltrate logs or data to an attacker-controlled storage account.
This rule detects the addition of new certificates or client secrets to Azure App Registrations or Service Principals by a user who is not recorded as an owner of that application in the last 90 days. This behavior is a common persistence and privilege escalation technique used by attackers to maintain access to cloud environments.
This rule detects potential privilege escalation activity associated with the abuse of CTFMON related objects (named pipes, symlinks, junctions) which may be used in conjunction with high-privilege operations (like SeDebugPrivilege or SeImpersonatePrivilege) to elevate access to SYSTEM. It correlates access events for CTF objects by processes (other than the legitimate ctfmon.exe) with subsequent sensitive privilege assignments within a short time window.
This rule detects various methods used to extract credentials protected by the Windows Data Protection API (DPAPI). It covers multiple vectors, including Mimikatz DPAPI module usage, unauthorized loading of the dpapi.dll library, suspicious access to browser or WiFi credential stores, and cross-process memory access to the LSASS process to extract DPAPI master keys.
Detects the execution of MAVInject.exe (Microsoft Application Virtualization Injector) with the /INJECTRUNNING parameter, a technique used to inject malicious code into a running process to evade detection.
Detects the creation of Kubernetes pods with dangerous security settings that could lead to container escape or privilege escalation. This includes pods configured with hostNetwork enabled, allowing privilege escalation, running as root (UID 0), or abusing capabilities.
Detects post-exploitation persistence activity following a DirtyClone (CVE-2026-43503) privilege escalation. The rule monitors for the creation of local user accounts via binaries like useradd and usermod, as well as unauthorized modifications to sensitive Linux configuration files such as /etc/sudoers or /etc/shadow, specifically when executed with root-level privileges.

Detects WinRAR creating a malicious VBS/VBE script within the Windows Startup folder using NTFS Alternate Data Streams, a behavior associated with the exploitation of CVE-2025-8088 by the Gamaredon threat group.

Detects high frequency administrative modifications, such as user creation/deletion, password resets, or group membership changes, performed by service accounts associated with Azure AD Connect or Microsoft Entra Connect. This behavior may indicate account compromise where a service principal is being abused to perform bulk identity management operations.
Detects unauthorized or suspicious modifications to critical Linux configuration directories (e.g., cron, rc, init, ipsec) or specific application-related paths by processes not typically associated with system management or package maintenance. The rule further elevates risk when specific indicators like LD_PRELOAD, LD_LIBRARY_PATH, or known malicious string artifacts are present in the command line or file path.
Detects the execution of known exploit binaries or the compilation of source files associated with the Linux PACKET_EDIT_MEME exploit (CVE-2026-46331). The rule monitors for specific binary names associated with the exploit, execution of these binaries from common staging directories (/tmp, /dev/shm, /run), and the use of GCC or CC compilers to build the exploit source files.
Detects unauthorized shells (bash, sh, dash, zsh) spawned as root from common setuid binaries (su, sudo, newgrp) by an unprivileged user. This behavior is indicative of the CVE-2026-46331 'pedit COW' vulnerability, where a local attacker performs page cache poisoning on a setuid binary to execute arbitrary code as root without disk modification.
Detects potential malicious persistence mechanisms (scheduled tasks, WMI event subscriptions, or Registry Run keys) initiated by Python executables or PyInstaller-bundled processes. This behavior is associated with information stealers that use these methods to maintain presence on a compromised host.
