Detects unauthorized access or modification attempts to cryptocurrency wallet files (specifically MetaMask and Phantom browser extensions) by non-browser processes. This behavior is indicative of credential theft or wallet exfiltration by malicious software.
Detects instances where JavaScript runtime processes (node, npm) execute specific peer-related or verification scripts and subsequently access sensitive system files or directories, such as SSH configurations, AWS credentials, or browser data, within a 5-minute window.
This rule detects when processes other than standard web browsers (Chrome, Edge, Firefox, Brave, Opera) attempt to read sensitive browser data files such as 'Login Data', 'Cookies', or 'Web Data'. These files contain stored credentials and session information, and unauthorized access is a common technique used by credential-stealing malware to exfiltrate sensitive user information.
Detects two suspicious behaviors related to OpenSSH. The first scenario identifies unauthorized modifications, creations, or renames of core OpenSSH binaries (/usr/sbin/sshd, /usr/bin/ssh, /usr/bin/scp) that are not initiated by common package managers, which could indicate persistence mechanisms or backdooring. The second scenario monitors ssh/sshd/scp processes creating or modifying files in common temporary or world-writable directories (/tmp, /var/tmp, /dev/shm, etc.), which is often indicative of credential harvesting or data staging.
This rule detects web browser processes (Chrome, Edge, Brave, Electron) making network requests to 'raw.githubusercontent.com' that contain keywords indicative of sensitive data, such as 'credential', 'secret', 'password', 'token', 'api_key', or '.env'. This behavior may indicate an adversary attempting to download configuration files or sensitive credentials hosted on GitHub.
Detects file operations (creation, modification, deletion, renaming) involving common SSH key files (id_rsa, id_ed25519) or files located within .ssh directories, initiated by processes typically associated with AI/LLM tools (chatgpt, perplexity, etc.) or generic process names. This may indicate an attempt to exfiltrate or manipulate authentication credentials by unauthorized applications.
Detects unauthorized processes attempting to access or perform operations on sensitive files such as browser credentials, SSH keys, crypto wallets, and password manager databases. The rule specifically looks for non-standard or unsigned processes interacting with a high volume of these files in a short time frame, which is indicative of credential harvesting by infostealer malware like Lumma, Redline, or Vidar.
This rule detects instances of the 'node.exe' process accessing file system paths associated with common browser-based cryptocurrency wallet extensions (such as MetaMask, Phantom, Coinbase Wallet, etc.). This behavior is highly suspicious as it indicates a potential attempt to steal local wallet data or seed phrases.
Detects unauthorized access (creation, modification, renaming, or deletion) to sensitive local credential files by the Node.js runtime process (node.exe/node). This behavior is indicative of infostealers, specifically noted in the Miasma/MYRA activity associated with the Polymarket Trap campaign, where malicious packages attempt to exfiltrate AWS, SSH, NPM, Python, Docker, and GPG credentials.
This rule detects when a Node.js process accesses sensitive files associated with cryptocurrency wallets (e.g., MetaMask, Phantom, Coinbase Wallet) or browser extension storage directories. This behavior is highly indicative of information-stealing malware attempting to extract private keys, wallet configuration files, or sensitive browser session data.
Detects the creation or writing of files within AppData directories matching specific naming patterns associated with Remcos RAT activity. Remcos typically generates files with a prefix of 'time_' or 'wnd_' followed by a timestamp string in these locations to store collected data or screenshots.
Detection rule monitoring for indicators of compromise related to SolarWinds Serv-U, including anomalous Content-Encoding headers, unexpected child process execution, large file staging indicative of data exfiltration (Cl0p-style), outbound exfiltration, SQL injection artifacts, and unauthorized LDAP/Active Directory object enumeration by the Serv-U process.
Detects anomalous activity associated with information stealing malware, including unauthorized access to browser credential files (Login Data, Cookies), remote thread injection into browser processes, outbound connections to the Telegram API by non-browser processes, and rapid bulk access to multiple sensitive credential or crypto wallet files.
Detects anomalous activity associated with the 'SmartWindow' browser exploitation technique, specifically: Firefox communicating with the local SmartWindow PoC C2 API on port 8765, Firefox spawning unexpected child processes, or unauthorized processes accessing Firefox's 'places.sqlite' database to harvest browsing history or private session data.
Detects Python processes attempting to read sensitive credential files (Login Data, Cookies, logins.json, key4.db) from Chrome, Firefox, and Edge directories. This behavior is indicative of the InvisibleFerret infostealer, which targets browser-stored credentials on compromised developer workstations.
Detects Python-based processes accessing sensitive local cryptocurrency wallet files and directories, including MetaMask extension storage, Exodus wallet, and Bitcoin wallet files, which are known targets of the InvisibleFerret infostealer.
Detects access or modification of cloud provider credential and configuration files by common script interpreters or code editors (python, node, vscode), which may indicate credential theft or misuse by an adversary.
Detects instances where scripting processes (Python, Node.js) accessed SSH key files or configuration files and subsequently initiated an outbound network connection within 60 seconds, which may indicate potential exfiltration of credentials or unauthorized access.
Detects non-browser processes accessing sensitive browser data files (such as Login Data, Cookies, or key stores) followed by network activity to known suspicious, cryptocurrency, or potential malware-hosting domains. This behavior is indicative of credential theft and exfiltration by information-stealing malware.
Detects access, copying, or creation of files within common cryptocurrency wallet directories, as well as registry lookups related to Bitcoin data directories. This behavior is often indicative of info-stealing malware or an adversary attempting to exfiltrate digital currency assets from a compromised host.
Detects execution of sensitive administrative binaries (rm, chmod, chown) targeting critical system files or directories, or direct interaction with sensitive system files and configuration logs which may indicate unauthorized data access or evidence tampering.
