Malicious code in computerrock-babel-preset-react-app (npm)
Details
The package impersonates the well-known babel-preset-react-app under a fake org-style prefix and ships no Babel preset code. package.json declares "preinstall": "node index.js", which runs automatically on npm install. index.js collects hostname, platform, arch, homedir, username/uid/gid/shell, OS info, current working directory, and the output of `whoami` and `id`, then POSTs the JSON payload to a hardcoded https://0bccssrkeubggq24k750nrw0erki88wx.oastify.com/detox56 URL (a Burp Collaborator out-of-band exfiltration host). The package's only function is reconnaissance and exfiltration of installer-side identifiers to an attacker-controlled host.
