Package is a dependency-confusion lure targeting Zomato's internal namespace. package.json declares a preinstall hook that runs curl on every npm install, posting the installer's hostname (hostname -f), username (whoami), current working directory, and the entire process environment (base64-encoded via env | base64 -w0) over plain HTTP to an interactsh out-of-band collector at d8s0b82plbq3u5sb2vo0sb3a9obr4yjt7.oast.site. The URL path embeds the package name and the form fields exfiltrate host, user, cwd, and env, so any CI/developer environment that misresolves Zomato's internal package name to this public release leaks AWS keys, GITHUBTOKEN, NPMTOKEN, and any other secrets exposed in the environment. A preuninstall hook performs a similar host beacon. The package's own functionality is a stub (index.js exports only {name, version}); its sole purpose is the install-time beacon. The description string self-identifies as Zomato's PDF generator service, confirming the dependency-confusion reconnaissance intent against Zomato's private namespace.
