Detects the presence of known artifacts associated with the SparroWocky loader and backdoor, specifically identifying the file names 'winfsp-x64.dll' and 'DukeQt.dll', or files matching known SHA1 hashes of SparroWocky samples. The presence of these files on a host is a strong indicator of compromise.
Detects anomalous thread execution call stacks indicative of the SparroWocky anti-forensic evasion technique. This method involves spoofing thread start addresses and call stacks by injecting or manually manipulating stack frames to include legitimate-looking system functions (e.g., BaseFlushAppcompatCacheWorker, BaseCheckVDMp) alongside malicious execution patterns involving NtDelayExecution and SleepEx to hide the true origin of code execution.
Detects web server processes (e.g., w3wp.exe, nginx.exe, tomcat.exe) spawning command-line interpreters or utilities that could indicate remote code execution, web shell activity, or post-exploitation discovery/download attempts.
Detects the use of database or archiving command-line utilities to export data related to RADIUS services. The rule filters out known backup service accounts and authorized backup processes, flagging activity that occurs outside of standard business hours or is performed by accounts not explicitly designated for administrative or database maintenance tasks.
Identifies instances of Google Chrome running on endpoints with version numbers below the threshold patched for CVE-2026-85046. This detection focuses on specific build numbers (e.g., 152.0.7977.82 for Windows/Linux) to identify potentially vulnerable browser installations in the environment.
Detects network connections to command-and-control infrastructure associated with the JeetBot/Twitch Enhanced Viewer malicious browser extension. The rule triggers on connections to known malicious domains or IPs, as well as specific API endpoints on ambiguous domains that are used for exfiltrating Twitch OAuth tokens.

This rule detects potentially malicious child processes spawned by Visual Studio Code (Code.exe) when using VS Code tasks (tasks.json). It identifies suspicious CLI arguments often associated with downloading, executing, or obfuscating scripts (e.g., PowerShell, curl, python, mshta) that are not part of standard development workflows like npm, yarn, or git, which are explicitly filtered out as noise.
This rule detects non-standard processes attempting to access sensitive web browser files (e.g., 'Login Data', 'Cookies', 'key4.db') that are typically only accessed by legitimate web browsers. It excludes known browser processes and trusted security or sync applications to identify potential credential theft attempts.

It excludes known browser processes and trusted security or sync applications to identify potential credential theft attempts.
Detects suspicious use of Windows API functions (SetWindowsHookEx) often associated with keylogging, correlated with the presence of temporary staging files in common directories (e.g., Temp, AppData). The rule excludes known legitimate applications that frequently utilize system hooks.

This rule monitors for the presence or execution of files matching a known set of SHA256 hashes associated with the 'DXSCAN' malware, utilizing both device file and process events.

Detects file and process activity associated with the Hermes ransomware, specifically targeting the presence of 'SOUL.md' files, '.hermes' file paths, and the 'HERMES_DISABLE_SAFETY=1' command-line argument.
Detects persistence attempts related to the NetSupport Manager remote access tool by monitoring modifications to Windows Registry keys associated with run keys, Winlogon notification packages, and services.
