Cisco NVM - Browser Spawned Unix Shell with External Connection

Detects a Unix-based (Linux or macOS) browser process spawning a Unix shell that establishes an outbound connection to an external destination. This browser-to-shell execution chain may indicate malicious browser content, drive-by execution, a compromised website, or abuse of a browser extension on Linux or macOS systems. The behavior may also occur during legitimate development, installation, automation, or enterprise software workflows.
