This rule detects a node.exe process initiating a network connection to a specific remote IP (69.48.229.140) on port 8080, followed by the termination of that same process within 45 seconds of the connection. This behavior is indicative of a short-lived beaconing process or an ephemeral network task associated with command-and-control activity.
Detects attempts to terminate security-related processes (AV/EDR) using common administrative tools including taskkill.exe, wmic.exe, and PowerShell Stop-Process. This behavior is frequently observed during the pre-encryption phase of ransomware attacks, such as Nova and Gentlemen, to evade detection.

Detects a behavioral pattern characteristic of Everest ransomware, where a sequence of rapid process terminations occurs within a 20-second window. The rule identifies the coordinated termination of security/analysis tools, antivirus/backup/database services, and other high-memory processes on a single device, excluding known legitimate maintenance processes.

This rule detects activities associated with the MacSync backdoor, specifically focusing on persistence mechanisms such as LaunchAgent manipulation, .repair-run scripts, and suspicious GIT hook usage. It also correlates these events with the termination of macOS notification agents (BTMNotificationAgent, NotificationCenter, BackgroundTaskManagementAgent), which is a tactic used to suppress security alerts during malicious operations.
Detects a coordinated attack sequence where a browser process is terminated, followed immediately by the execution of an unsigned Python interpreter from a suspicious location (temp/downloads folder), which is then followed by the installation of an unsigned browser extension. This pattern mimics ClickFix and browser-based RAT lure campaigns.
Detects the loading of the malicious NvFsFilter driver (a BYOVD technique often used by the Rapuncel infostealer) followed immediately by a mass burst of process terminations, indicating an attempt to disable security software.
This rule detects a credential theft pattern where a browser process is forcefully terminated using taskkill, followed shortly by the creation of a 'wd_tmp.db' file in browser user data directories. This behavior is indicative of malware attempting to stage and exfiltrate browser credentials like cookies and login data.

This rule detects the loading of known-vulnerable or malicious kernel drivers (BYOVD) followed by the termination of major EDR or security-related processes on the same host within a 10-minute window. This behavior is indicative of an adversary attempting to disable security controls to evade detection after achieving kernel-level privileges.
Detects rapid termination of specific mobile messenger applications (Max) within seconds of starting, while indicators of the Frida dynamic instrumentation tool are concurrently detected on the device. This pattern suggests the application is identifying the presence of a hooking/instrumentation environment and self-terminating as a defense mechanism. The detection is further correlated with failed connection attempts to the application's backend.
Detects the installation or configuration of the NvFsFilter (Alinubx.sys) persistence driver, often associated with malicious behavior that continuously terminates security software processes to allow for persistent unauthorized activity after system reboots.
This rule detects the loading of the known vulnerable NvFsFilter (Alinubx) driver, followed by the abrupt cessation of multiple active AV/EDR processes within a 30-minute window. This behavior is indicative of a Bring Your Own Vulnerable Driver (BYOVD) attack, where the driver is used to execute kernel-mode commands to terminate security software, bypassing standard protection mechanisms.
Detects bulk or repeated attempts to stop security-related services and processes (such as EDR or AV agents) or modification of Windows Defender registry keys. This behavior is indicative of a pre-encryption phase in ransomware attacks where adversaries attempt to neutralize endpoint defenses.
