Detects execution of potentially suspicious processes ('Launcher.exe' or 'GapiUpdate.exe') originating from ClickOnce-related processes ('dfsvc.exe' or 'rundll32.exe' with 'dfshim.dll'). ClickOnce is often abused to proxy execution of malicious code, allowing adversaries to execute applications from user-writable directories without administrative privileges.
This rule detects potentially malicious activities aimed at credential harvesting and system recovery inhibition. It monitors for the execution of vssadmin.exe with arguments to list shadow copies (often a precursor to deletion) or references to DPAPI master keys in command lines. Additionally, it identifies unauthorized processes attempting to access sensitive browser-based credential files (e.g., Login Data, Cookies, key4.db) from standard browser installation paths, specifically excluding legitimate browser and update processes.

This rule detects potential automated cryptocurrency wallet draining activity by correlating the execution of known stealer processes (such as GapiUpdate or NeedleStealer) with subsequent outbound network connections to suspicious command-and-control domains or API endpoints within a 30-minute window.
Detects the execution of a process named 's.exe' (or similar match) with a command-line argument consisting of a single character 's' followed by a digit. This pattern is commonly associated with malicious usage or obfuscation, where 's.exe' might be a renamed utility or a malicious artifact attempting to masquerade or execute specific tasks.
Detects instances where common web browsers (Chrome, Edge, Firefox, Safari) or related desktop applications spawn shell interpreters (PowerShell on Windows, bash/zsh/sh on macOS) with command-line arguments indicative of malicious activity, such as base64-encoded payloads, hidden windows, or remote script downloading.
Detects the presence of known synchronization objects (mutexes, events, or shared memory) associated with SparroWocky malware, identified via Microsoft Defender DeviceEvents and DeviceProcessEvents telemetry. The rule monitors for these specific markers in process creation, remote thread creation, and named pipe events.
This rule detects potential masquerading activity where an executable is signed by 'Discord Inc' or 'Lenovo' but the image path does not correspond to expected legitimate installation directories or filenames. It flags processes that claim a trusted publisher identity while residing in suspicious or unexpected locations.
Detects ClickFix-style activity where a web browser or common application launcher spawns a terminal or PowerShell process to execute obfuscated, copied, or piped commands. This behavior often indicates a social engineering attack where a user is tricked into manually executing a malicious command script.
Detects anomalous child processes spawned by a Chrome renderer process. This behavior is often indicative of exploitation attempts, such as the BlueMoon exploit kit leveraging CVE-2026-85046, where a compromised renderer attempts to escape the sandbox or execute arbitrary code in the host process.
Detects the spawning of cmd.exe from 7z.exe, which is characteristic of the GRAYRABBIT malware sideloading chain where 7z.exe is used to load malicious DLLs (e.g., boy.dll, core.dll) that subsequently initiate an interactive reverse shell.

Detects child processes spawned by 7z.exe when it is executed from the 'C:\Users\Public\Documents\' directory. This is consistent with the behavior of the GRAYRABBIT backdoor, where a trojanized 7z.dll or boy.dll is sideloaded into the 7z.exe process to facilitate silent arbitrary process execution.

Detects behavior indicative of the GRAYRABBIT malware, specifically identifying network connections to known command-and-control (C2) infrastructure (mail.uaiubifas.top) followed within a short time window (10 minutes) by reflective in-memory module loading activities within the same process. This pattern suggests the delivery and execution of a plugin or additional malicious payload without writing the binary to disk.
Detects potential exploitation of CVE-2025-3248 in Langflow by identifying suspicious inbound network traffic targeting the /api/v1/validate/code endpoint, correlated with subsequent python child processes containing base64 decoding and execution primitives such as eval, exec, or subprocess.
Detects unauthorized access and data retrieval attempts from a MinIO object storage instance using default administration credentials (minioadmin:minioadmin). The rule monitors both command-line execution of MinIO client (mc) operations and network connections to MinIO service ports (9000/9001) that involve the use of the default credential pair.
Detects unauthorized access and data retrieval attempts from a MinIO object storage instance using default administration credentials (minioadmin:minioadmin). The rule monitors both command-line execution of MinIO client (mc) operations and network connections to MinIO service ports (9000/9001) that involve the use of the default credential pair.
Detects the execution of PostgreSQL dump utilities (pg_dump, pg_dumpall) initiated directly by application-level processes like Langflow or Python, rather than through standard system-level task schedulers. This behavior is indicative of unauthorized data collection or staging of database contents by an application process.
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.
