The cabin in the woods is a metaphor for an unmonitored public software repository, where a dependency not tracked by developers can unleash devastating consequences. The incantations to unlock demonic possession represent the risks of ignoring security vulnerabilities and lack of protection. Unwitting temporary residents, such as developers and processes, are vulnerable to attacks without knowledge or defense. The book in the cabin represents the dependency that is not being monitored, while the demonic possession symbolizes the chaos and destruction caused by neglecting software supply chain security.
