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 instances where a user account performs a password update without any preceding or associated account verification events (such as email verification, reset requests, or action execution) within a short timeframe. This behavior can be indicative of account compromise where an adversary modifies credentials for a compromised user account.
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 outbound TLS traffic behavior consistent with the WaterPlum RAT, characterized by periodic, low-volume connections to non-CDN/cloud providers. The rule identifies potential beaconing activity by monitoring TLS SNI fields against a list of known legitimate service providers and applying a frequency threshold.
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.
