Detached node.exe child spawned via lib/caller.js middleware payload
Detects a Node.js process spawning a detached child process that executes a script named 'caller.js'. This behavior is consistent with the 'nodemon-sudo' or 'tslint-conf' supply chain attacks, which leverage detached child processes to execute malicious second-stage payloads while suppressing console output, effectively creating a persistent, hidden backdoor.
