This rule detects suspicious process injection activity directed at Chrome or Edge browser processes, followed immediately by file access to sensitive browser data files like 'Login Data' or 'Cookies'. This pattern is indicative of an adversary attempting to steal credentials or session cookies from a user's web browser memory and disk storage.
Detects instances where AI-assisted coding tools or command-line interfaces spawn scripting runtimes (Node.js, Python) to access sensitive files such as SSH keys, cloud provider credentials, or Kubernetes configurations. This behavior may indicate an AI coding assistant being coerced or misconfigured to exfiltrate secrets from the development environment.
Detects a sequence of potentially malicious actions indicative of credential theft, including LSASS memory access for dumping, followed by the acquisition of browser or cryptocurrency wallet files, and the subsequent staging of data in temporary directories, all correlated by the same process and device within a 15-minute window.

Detects the Comet browser process, typically associated with AI-agent operations, accessing sensitive browser profile files (e.g., History, Bookmarks, Login Data, Cookies) followed by outbound network communication within a 15-minute window, excluding known legitimate paths.

Detects instances where processes other than the legitimate Telegram Desktop application or its updater attempt to access files within the Telegram Desktop 'tdata' directory. This directory contains session information, which can be harvested by malicious actors to hijack user sessions or access sensitive information.

This rule detects activity associated with the exploitation of PaperCut vulnerabilities. It looks for connections to known malicious IP addresses, the presence of specific credential harvesting tools, reconnaissance commands (whoami, tasklist) executed by the PaperCut application (pc-app.exe), suspicious PowerShell downloads of AnyDesk, and unauthorized access to PaperCut configuration files or log files containing known exploit strings.
Detects the MovieReaper payload behavior where a specific file manager process masquerading as a legitimate system utility (msedge.exe) performs mass file enumeration or access followed by suspicious outbound network connections, indicative of data staging and exfiltration.

Detects unauthorized access or decryption attempts related to Group Policy Preferences (GPP) files stored in the SYSVOL share. Attackers often target these files to retrieve credentials stored in the 'cpassword' attribute, which can be decrypted using publicly known keys.
Detects unauthorized processes attempting to access sensitive application data files such as browser cookies, local state, or data stored by applications like Discord, Telegram, and Steam, which are frequent targets for credential-stealing malware.
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.
Detects unauthorized access attempts to browser credential files (such as Login Data, key4.db, and cookies) by non-browser processes. This behavior is indicative of the Rapuncel infostealer, which harvests stored browser credentials after attempting to disable or bypass security solutions.

Detects unauthorized access to critical browser files such as cookies, login data, and local state files. These files contain sensitive information such as authentication cookies and stored credentials, which are primary targets for infostealer malware.
