MacOS Emond Launch Daemon
Detects additions to the Emond Launch Daemon that adversaries may use to gain persistence and elevate privileges.
Startup Item File Created - MacOS
Detects the creation of a startup item plist file, that automatically get executed at boot initialization to establish persistence. Adversaries may use startup items automatically executed at boot initialization to establish persistence. Startup items execute during the final phase of the boot process and contain shell scripts or other executable files along with configuration information used by the system to determine the execution order for all startup items.
Atomic MacOS Stealer - Persistence Indicators
Detects creation of persistence artifacts placed by Atomic MacOS Stealer in macOS systems. Recent Atomic MacOS Stealer variants have been observed dropping these to maintain persistent access after compromise.
Axios NPM Compromise File Creation Indicators - MacOS
Detects file creation events linked to the Axios NPM supply chain compromise on macOS devices. Axios is a popular JavaScript HTTP client. On March 30, 2026, malicious versions (1.14.1, 0.30.4) were published to npm, injecting a dependency (plain-crypto-js@4.2.1) that executed a postinstall script as a cross-platform RAT dropper.
Python Path Configuration File Creation - MacOS
Detects creation of a Python path configuration file (.pth) in Python library folders, which can be maliciously abused for code execution and persistence. Modules referenced by these files are run at every Python startup (v3.5+), regardless of whether the module is imported by the calling script. Default paths are '\lib\site-packages\*.pth' (Windows) and '/lib/pythonX.Y/site-packages/*.pth' (Unix and macOS).
