This rule detects the presence or execution of a file named 'GlobalProtect.exe' within the Palo Alto GlobalProtect directory. It focuses on identifying potentially masqueraded or unauthorized binaries by monitoring file events and associated process execution. This pattern is commonly used by attackers to disguise malicious files as legitimate security software to evade detection.
Detects anomalous child process execution by Chromium-based browsers (e.g., chrome.exe, msedge.exe, brave.exe). This behavior is indicative of potential exploitation of browser vulnerabilities such as CVE-2026-85046, where a memory corruption vulnerability is leveraged to escape the browser sandbox and execute arbitrary commands via interpreters like cmd.exe or powershell.exe.
Detects the execution of an unsigned binary named '.macos' located within a 'Contents/MacOS/' directory structure, which is a common pattern for malicious applications attempting to masquerade or hide their execution profile on macOS.
This rule detects potentially suspicious activity involving the execution of node.js, npm, or curl where a specific node version (node-v20.11.1-darwin-x64) and a file named 'parser.js' appear in the command line within a short period. This pattern is indicative of a developer or attacker staging tools and scripts on a macOS system.
Detects the execution of processes named 'ProManager.exe' or 'ProManagerServicedc894.exe', which may be indicative of unauthorized software or potentially malicious activity.
Detects the execution of an executable file located within the Windows Temp directory structure via the command prompt (cmd.exe). This pattern is commonly associated with the execution of downloaded payloads, droppers, or staged malware that are moved to temporary directories to evade initial detection.

This pattern is commonly associated with the execution of downloaded payloads, droppers, or staged malware that are moved to temporary directories to evade initial detection.
Detects attempts to modify or disable the Windows Update service (wuauserv) using command-line utilities (sc.exe, cmd.exe, powershell.exe) in a context involving 'LockAppHost.exe'. This pattern is often associated with unauthorized attempts to tamper with security update mechanisms to prevent system patching.
Detects attempts to modify or disable the Windows Update service (wuauserv) using command-line utilities (sc.exe, cmd.exe, powershell.exe) in a context involving 'LockAppHost.exe'. This pattern is often associated with unauthorized attempts to tamper with security update mechanisms to prevent system patching.
Detects the use of 'schtasks.exe' to disable critical Windows Update or ExploitGuard Malware Removal tasks when initiated by 'LockAppHost.exe'. This behavior is highly irregular, as the LockAppHost process is typically associated with the Windows Lock Screen and should not be modifying security-related scheduled tasks.
Detects malicious network connections, file downloads, or process execution associated with the REVSTEALER malware campaign, which utilizes hijacked YouTube channels to distribute fake game-cheat videos that lure users into downloading 'resightloader.exe' from specific malicious domains.

Detects the execution of cmstp.exe with the /au parameter, which is commonly used to install malicious INF files, when initiated by LockAppHost.exe. This pattern is often indicative of an attempt to bypass application control or achieve privilege escalation by leveraging the legitimate Microsoft Connection Manager Profile Installer.

This pattern is often indicative of an attempt to bypass application control or achieve privilege escalation by leveraging the legitimate Microsoft Connection Manager Profile Installer.
This rule detects processes with names commonly associated with system daemons (e.g., kworker, fc-cache, chronyd, gvfsd) that are executing from non-standard, suspicious directories such as /tmp/ or user-defined hidden folders. This behavior is indicative of an adversary attempting to masquerade malicious binaries as legitimate system processes to evade detection.
Detects direct unauthorized modifications to Linux crontab files or the addition of specific known malicious cron job patterns. It specifically monitors for file changes in '/var/spool/cron' and correlates them with 'crontab -e' process executions to identify manual versus automated or malicious modifications. Additionally, it checks for specific hardcoded malicious patterns commonly associated with known threat activity.

This behavior is indicative of an adversary attempting to masquerade malicious binaries as legitimate system processes to evade detection.
This rule detects potentially malicious JavaScript files associated with known malicious patterns or suspicious 'preinstall' script behavior within Node.js environments. It monitors for the execution of specific suspicious filenames or the use of common Node.js package management tools (npm, yarn, etc.) in contexts suggesting code generation or build-time abuse.
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.
