This rule detects attempts to dump the macOS Keychain via a remote SSH connection. It specifically looks for the string "security dump-keychain" within TCP traffic on port 22 (SSH). This command is used to extract credentials and other sensitive information stored in the macOS Keychain.
This rule detects a high volume of file creation events (100 or more within an hour) occurring in common development-related directories such as 'node_modules', 'packages', or 'vendor'. This activity can be indicative of legitimate software development processes like dependency installation or project builds. However, it can also signal malicious activity, particularly if observed on systems not typically used for development, or as part of a supply chain compromise where malicious dependencies are being introduced or built.
Detects hiding a user home folder with chflags, complementing account-level hiding
documented in T1564.002.

Detects the creation or modification of specific LaunchAgent plist files used by the arm64 and x86_64 variants of SStar Agent malware on macOS for persistence. The rule looks for file events (creation, modification, rename) within the /Library/LaunchAgents/ directory, specifically targeting 'com.wpnuersvc.agent.plist' and 'com.googleupdate.sstaragent.plist' filenames.
This rule detects the creation or modification of the '.vscode/extensions.json' file. This file is critical for managing extensions within Visual Studio Code environments. Attackers can exploit modifications to this file, as demonstrated in recent zero-day attacks, to introduce malicious extensions, potentially leading to code execution or other forms of compromise within a developer's environment. The detection focuses on file system events (creation and modification) targeting this specific configuration file.
Detects access to clipboard content via osascript, which may be used for data collection but also occurs in legitimate clipboard utilities and automation scripts
Detects hiding a user home folder with chflags, complementing account-level hiding, documented in T1564.002.
Detects delete/create sequences on the same /Users/ path within a short time window,
consistent with account attribute laundering during hidden user setup.

This rule detects when a file containing both ".plist" in its HTTP URI and "LaunchDaemon" in its content is delivered via HTTP. This combination suggests the download of a macOS LaunchDaemon property list file, which could be used for persistence or privilege escalation on macOS systems.
This rule detects the string "launchctl load" within TCP traffic on port 22 (SSH). This indicates an attempt to load a launchd service on a macOS or Linux system via a remote SSH connection. This activity could be legitimate system administration but also could be indicative of an attacker establishing persistence or executing malicious services.
Detects browser processes making DNS queries or network connections to BNB Smart Chain RPC endpoints (and related EVM-compatible chain RPCs). This technique is a signal for EtherHiding-style attacks where malicious JavaScript injected into compromised websites queries smart contracts for payload retrieval. This generalizes beyond ClearFake to catch UNC5342 (North Korean DPRK) and other EtherHiding adopters documented since October 2025.
Detects command-line attempts to access, dump, or export macOS Keychain data using the 'security' utility. This behavior is commonly exhibited by infostealers, such as MacSync Stealer, targeting saved passwords, cryptocurrency wallets, and developer credentials.
This rule detects the creation of common ransomware ransom note filenames on a device. It triggers when two or more distinct ransom note files are created within a 5-minute window, indicating potential ransomware activity.
Detects the execution of the GitHub CLI command used to print the active authentication token, which is abused by the Shai-Hulud worm to steal developer credentials.
Detects the destructive command line used by the Miasma campaign's dead man's switch to wipe the user's home directory upon token revocation. Specifically looks for 'rm -rf ~/; rm -rf ~/Documents' executed by 'rm' or 'rm.exe'.
Detects attempts to disable Gatekeeper assessment or modify System Integrity

sub-500 UID accounts from the login screen and System Settings.
sub-500 UID accounts from the login screen and System Settings.
This rule detects outbound network connections from devices to IP addresses identified as malicious by a threat intelligence feed. It joins device network events with threat intelligence indicators, specifically looking for successful connections or connection requests to IPs with a confidence score greater than 50. The alert provides details about the device, the remote IP, the initiating process, and the threat intelligence context.
Detects process executions or command-line arguments referencing the installation of identified malicious npm packages, specifically 'chalk-tempalte', '@deadcode09284814/axios-util', 'axois-utils', and 'color-style-utils'. These packages are associated with 'Shai-Hulud clones' and 'Phantom Bot' campaigns, often involving typosquatting or similar deceptive naming conventions to trick developers into installing malicious dependencies.
This rule detects attempts to modify the Info.plist file on macOS systems to include 'LSUIElement' with a value of '<true/>'. This modification can be used by malware or unwanted applications to hide their presence from the macOS Dock and menu bar, effectively bypassing user detection and making the application run as a background process. The rule specifically looks for these two content strings within HTTP file data flowing to the client.
