Detects a user-mode process attempting to set an opportunistic lock (oplock) on wermgr.exe within a Volume Shadow Copy (VSS) snapshot. This behavior is associated with the RoguePlanet exploit chain (CVE-2026-50656), which leverages VSS snapshots and file locking to trigger a TOCTOU race condition against the Microsoft Defender (MsMpEng.exe) scanner.

This rule monitors for Node.js processes accessing sensitive configuration files, environment files, or credential stores (such as AWS credentials). It also triggers when command line arguments or file contents contain patterns indicative of infostealer activity, including specific indicators related to the Polymarket campaign or credentials collection functions like Git or Docker credential harvesting.

This rule detects non-Mozilla processes that systematically access sensitive Firefox browser files such as logins.json, key3.db, key4.db, and cookies.sqlite. Repeated access by processes not associated with the Mozilla Corporation or the Firefox browser suite is indicative of credential harvesting attempts by malicious software.

Detects unauthorized access, copy, or read operations against Chromium-based browser cookie database files by processes other than standard browsers. This behavior is indicative of session hijacking, a technique observed in malware like TONResolver and Millenium RAT to extract authentication tokens for subsequent adversary-in-the-middle or session theft attacks.

Detects potential data exfiltration by monitoring interpreter processes (Python, Node.js) that access sensitive local credential/configuration files and subsequently connect to known cloud storage or code repository APIs (Dropbox, GitHub, Google Cloud). The rule correlates file access events with network connection activity.

005
Detects instances where scripting engines (Python or Node.js) access known SSH private key files and subsequently initiate a successful network connection to a non-private IP address within a 60-second window. This behavior is indicative of potential credential exfiltration or unauthorized remote access.

205
Detects instances where the Windows Error Reporting process (wermgr.exe) attempts to open files located within a Volume Shadow Copy path. This behavior is atypical and may indicate an attempt to access sensitive files from a shadow copy, a technique often used in credential dumping or discovery activities.

004
Detects unauthorized non-browser processes accessing Chrome Local State, Cookies, or Login Data files. This activity is indicative of credential harvesting by infostealers, such as the Glove Stealer/Yuta campaign, attempting to bypass App-Bound Encryption (ABE) by accessing browser configuration and data stores.

Detects unauthorized access to browser credential databases, cloud configuration files, and developer secret stores by processes spawned from Node.js or npm. This behavior is indicative of IronWorm and similar infostealers exploiting malicious npm package preinstall hooks to harvest sensitive developer credentials.

Detects the use of legitimate Windows system utilities (ntdsutil.exe, vssadmin.exe, esentutl.exe) to interact with the Active Directory database file (ntds.dit). This behavior is commonly associated with offline credential harvesting, where an attacker attempts to create a copy of the database to extract hashes offline.

This rule detects scenarios where Microsoft Teams initiates a potential screen-sharing session (via outbound network connections on specific ports) followed shortly by the access of VPN configuration files on the same host. This sequence may indicate an attacker using screen-sharing to view credentials or configuration details and subsequently attempting to utilize a VPN client.

Detects Node.js, NPM, or NPX processes attempting to read sensitive shell history files (e.g., .bash_history, .zsh_history). This behavior is characteristic of malicious activity such as infostealers attempting to harvest credentials or reconnaissance data from a compromised developer environment, notably observed in supply chain campaigns like the Polymarket Trap.
