Summary
Malicious code in zomato-logger (npm)
Details
On `npm install`, the package's preinstall lifecycle script in package.json runs curl to POST the installer's hostname, current user (whoami), working directory, and the entire environment (base64-encoded `env` output) to http://d8s0b82plbq3u5sb2vo0sb3a9obr4yjt7.oast.site/install/<base64-pkg> over plain HTTP. The destination is an Interactsh / oast.site out-of-band collaborator subdomain — infrastructure used to capture exfiltrated data from victim hosts. The package itself is a hollow stub (index.js exports only `{ name, version }`), and the metadata (`description: "Zomato logging library"`, repo URL git+https://github.com/zomato/zomato-logger.git) impersonates Zomato, consistent with a dependency-confusion attack targeting an org-internal package name. Any host that resolves and installs this package leaks every environment variable (including any CI secrets, tokens, and credentials present in the build environment) to the attacker.
