This rule detects the use of common command-line utilities (grep, find, bash, sh, awk) to search for sensitive files, such as SSH keys, configuration files containing credentials, or password-related patterns. The rule includes exclusions for common administrative, security, and backup tools that might legitimately perform such scans.
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.

Detects access to Gitea secrets and configuration (app.ini, JWT secrets, SSH host keys, deploy keys) via file writes/renames or process command lines referencing those paths alongside Gitea, matching the secret-extraction tradecraft observed in the Red Heron campaign.
Detects unauthorized processes attempting to access browser credential database files such as Login Data for Chromium-based browsers or logins.json and key4.db for Firefox. The rule filters out known browser processes to isolate potential credential harvesting or exfiltration activity.
Detects unauthorized processes attempting to access sensitive web browser files (login data, cookies, configuration) located in Chrome or Firefox profile directories. The detection excludes known browser-related processes and system processes, focusing on third-party or potentially malicious utilities that could be used to harvest credentials stored in these local files.
Detects unauthorized access to sensitive browser credential files (e.g., Chrome 'Login Data', Firefox 'logins.json' and 'key4.db') by processes other than legitimate browser executables. This behavior is indicative of credential harvesting attacks, such as those performed by BabylonRAT.
This rule detects the creation or modification of a file named 'ClipBoard.txt' within the directory 'AppData\Roaming\ConfigsEx\', as well as the creation of the 'ConfigsEx' directory using command-line tools. This behavior is indicative of an adversary staging sensitive information, such as harvested clipboard data, for potential exfiltration.

This behavior is indicative of an adversary staging sensitive information, such as harvested clipboard data, for potential exfiltration.
Detects high-volume filesystem activity (exceeding 300 operations in 5 minutes) initiated by 'claude-code' or 'claude' processes. This behavior may indicate an autonomous, patched, or jailbroken AI coding assistant performing mass file operations or reconnaissance without user confirmation.

Detects attempts to access sensitive files like environment variables (.env), cloud provider credentials (AWS/Azure), or Terraform state files via a web server interface, specifically targeting Vite development server deployments.
Detects processes that access sensitive browser credential or cookie files (e.g., Login Data, Cookies) followed by network activity within a 10-minute window, which is a common behavior pattern of information-stealing malware such as Amatera or ACR Stealer.
Detects unauthorized processes (e.g., cmd.exe, powershell.exe, node.exe) accessing sensitive web browser files like 'Login Data' or 'Cookies' in common browser directories. This behavior is indicative of credential theft or data exfiltration attempts.
Detects execution of Electron or Node.js processes attempting to export Telegram sessions, specifically targeting execution paths often used for staging or temporary storage (Temp, Roaming, ProgramData, Public folders).
Detects the 'Comet.exe' process, associated with the Perplexity Comet AI agent, accessing sensitive system files or configuration directories outside its expected scope. This pattern of file interaction is characteristic of unauthorized data collection or exfiltration attempts, specifically linked to the BragJack threat activity.

This rule detects potential execution of malicious files from removable media (e.g., USB drives). It monitors for a sequence of events where a removable drive is mounted, a file is subsequently created on that drive, and then that same file is executed within a short time window.
