Detects the execution of the 'su' binary preceded by command-line strings that are highly indicative of known Linux privilege escalation exploits, specifically those targeting vulnerabilities like PwnKit (CVE-2021-4034). The rule monitors for common exploit payloads or status messages (e.g., 'prctl PR_SET_DUMPABLE', 'fork userns mapper') associated with successful exploitation attempts that manipulate environment variables or process attributes to elevate privileges to root, while filtering out legitimate container-related processes.

Detects instances where a non-SYSTEM process attempts to open a handle to winlogon.exe. Since winlogon.exe typically runs as SYSTEM and manages user sessions, unauthorized access to its process handle is often a precursor to credential dumping or token manipulation attacks aimed at escalating privileges to SYSTEM.

Detects potential local privilege escalation via Windows ALPC (Advanced Local Procedure Call) heap-based buffer overflow by identifying a non-SYSTEM Chrome process tree spawning child processes with SYSTEM privileges. The rule specifically monitors for suspicious child binaries or paths characteristic of exploit payloads while excluding legitimate Chrome update and crash handler processes.

Detects suspected exploitation of CVE-2026-81963, an Elevation of Privilege vulnerability in the Windows Update stack. The rule monitors for the creation of reparse points, junctions, or symbolic links within update staging paths by Windows Update processes, followed by either the spawning of suspicious child processes or unauthorized file writes/renames outside of expected directories, which are indicative of a privileged link-following exploit.

Detects instances where LiteLLM, or related Python application processes (uvicorn, python), spawn a shell or command-line utility (bash, sh, id) under the root user account. This behavior is indicative of potential container breakout, application exploitation, or privilege escalation attempts originating from a web-accessible service.

Detects modifications to registry keys under 'Software\Classes\ms-settings' associated with the fodhelper.exe UAC bypass technique, where an adversary manipulates the registry to hijack execution flow and escalate privileges.

This rule detects potentially unauthorized root account activity by monitoring for 'root' logon events and privileged process execution (such as 'su' or 'sudo'). It flags sessions or commands that occur outside of defined business hours, originate from unapproved IP addresses, use unapproved accounts, or are executed via suspicious parent processes, providing a high-confidence indicator of anomalous administrative behavior.

Detects when a user who has successfully authenticated to a system is subsequently added to the 'Domain Admins' group within a 15-minute window. This behavior often indicates an adversary performing privilege escalation after gaining initial access to an account.

Detects the execution of known Windows accessibility binaries (e.g., sethc.exe, utilman.exe) where the internal metadata or original filename indicates that the process is actually cmd.exe. This is a common technique used by adversaries to gain unauthenticated command-line access with SYSTEM privileges via accessibility features, typically during the login screen process.

This rule detects potential tampering with the Huorong security product by monitoring for specific process names (HipsTray.exe, HipsMain.exe, HipsDaemon.exe, wsctrlsvc.exe, TrafficProt.exe) interacting with suspicious API calls or command lines indicative of token privilege manipulation, service blinding, or security product disabling/downgrade.

Detects direct SQL UPDATE operations on the pg_authid system table to modify privilege flags (e.g., rolsuper, rolcreaterole) without using the authorized ALTER ROLE statement. Such activity often indicates an attempt to escalate privileges or modify database user permissions in an unauthorized manner, bypassing standard auditing and role management processes.

Detects attempts to modify internal PostgreSQL system catalog tables (pg_authid or pg_proc) to grant superuser privileges or alter authorization records. This activity is commonly associated with exploiting logical decoding plugins to achieve persistence or privilege escalation in PostgreSQL environments.

This rule detects potentially malicious PowerShell execution patterns involving hidden windows, administrative elevation via 'Start-Process -Verb RunAs', and the targeting or execution of rsetup64.exe within specific system paths. It also flags execution chains where 'net session' commands, often used for discovery or local privilege verification, are piped to null and followed by or initiate the same target executables, suggesting lateral movement or persistence attempts.

Detects execution of shell interpreters (tar, sh, bash) by the Parallels Desktop dispatcher service (prl_disp_service) or usage of compression flags containing specific markers associated with UCP/ACTOR privilege escalation patterns, specifically when executed with root privileges or by a root user.

Detects interactive root shell requests via 'sudo -i' that occur shortly after a failed Parallels appliance installation or tar extraction event containing specific error codes or configuration markers (UCP_UID=0). This pattern aligns with the exploitation chain for CVE-2026-90894, where an attacker leverages an extraction failure to escalate privileges.
