Detects high-volume, automated file download or access activity originating from SharePoint Online, OneDrive, or Exchange Online within a 2-hour window. The rule identifies suspicious patterns involving a large number of distinct file events, potentially indicating automated scripts or tools (like python-httpx) performing mass data collection or exfiltration.

The rule identifies suspicious patterns involving a large number of distinct file events, potentially indicating automated scripts or tools (like python-httpx) performing mass data collection or exfiltration.
Detects anomalous, high-volume file access or download activity in Microsoft SharePoint Online or OneDrive for Business originating from a 'python-httpx' user agent. This pattern often indicates automated data collection or exfiltration attempts using programmatic tools.
Detects instances where browser processes or related credential files are accessed or targeted by process termination (e.g., taskkill.exe) followed by attempts to access sensitive files like Login Data, logins.json, or key4.db. This pattern is indicative of credential theft from web browsers.
Detects instances where browser processes or related credential files are accessed or targeted by process termination (e.g., taskkill.exe) followed by attempts to access sensitive files like Login Data, logins.json, or key4.db. This pattern is indicative of credential theft from web browsers.
This rule detects file access, creation, modification, or renaming operations involving sensitive files associated with cryptocurrency wallets (Bitcoin, Electrum, ElectrumSV), game account configurations (Battle.net, Steam, Minecraft), and browser-based cookies (Roblox). The rule filters out legitimate process interactions, identifying suspicious activity from unknown or unauthorized applications potentially attempting to exfiltrate credentials or session tokens.
Detects access to sensitive credential stores (KeePass databases, Firefox logins, SSH keys, VPN configuration files) by suspicious processes, specifically those associated with potential credential harvesting tools or unauthorized update binaries.
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.

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 instances where the Google Chrome browser process interacts with files or registry keys associated with audio and video capture devices, such as cameras and microphones. This may indicate unauthorized use of media peripherals by the browser process.
This rule detects a process loading English (.en-US) MUI resource files from the C:\Windows\System32\en-US\ directory when the initiating process is located outside of standard system directories (System32, SysWOW64, Program Files). This behavior is indicative of a masquerading or camouflage technique where a malicious executable attempts to mimic a legitimate system process by loading its localized resources.
Detects potential data exfiltration activity associated with the GRAYRABBIT threat actor, where a local file is accessed or modified by a process shortly before or after that same process initiates a network connection to a known GRAYRABBIT C2 endpoint over port 443.
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.
Detects unauthorized processes accessing sensitive web browser files (login data, cookies, local state) from suspicious or non-standard paths. This is a common behavioral pattern for infostealers attempting to exfiltrate user credentials and browser session tokens.
This rule detects potentially unauthorized access or large-scale extraction of sensitive RADIUS server configuration and credential databases. It monitors for common database management tools and commands used in conjunction with RADIUS-specific paths, particularly when executed by unexpected processes, during off-hours, or in a manner indicative of bulk data export.

It monitors for common database management tools and commands used in conjunction with RADIUS-specific paths, particularly when executed by unexpected processes, during off-hours, or in a manner indicative of bulk data export.
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.
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 various methods and tools used by adversaries to access, stage, or exfiltrate the Active Directory database (ntds.dit). This includes abuse of built-in Windows utilities such as ntdsutil, vssadmin, diskshadow, esentutl, and registry commands, as well as the use of known credential dumping tools like Impacket's SecretsDump and NinjaCopy.
This rule detects potentially unauthorized access to Microsoft Graph API resources (Mail or Files) following a device-code authentication event for the same user. It identifies scenarios where a previously unknown application client performs read operations within 24 hours of a device-code login, which is characteristic of 'ARToken' or 'EvilProxy' type device-code phishing and session proxy attacks.
Detects unauthorized processes accessing cryptocurrency wallet data files, including 'wallet.dat' or specific browser-based extension storage databases (e.g., MetaMask, Coinbase Wallet), which is indicative of the Rapuncel stealer attempting to exfiltrate sensitive wallet data.
