index.js line 5 exports a function that invokes /bin/bash to curl https://reverse-shell.sh/10.0.19.80:4443 and pipe the response to a shell, delivering an interactive reverse shell to the hardcoded endpoint 10.0.19.80:4443 on the host where the exported function is called. The destination is a hardcoded private-range IP, there is no authentication, no documentation of the behavior, and the fetched content is executed directly. The package's only exported functionality is this backdoor dropper.
