package.json declares both preinstall and postinstall scripts that run node callback.js, so the callback fires automatically on npm install with no user interaction. callback.js collects identifying data from the installer's machine — os.hostname(), os.userInfo().username, process.cwd(), the consuming package name@version, and process.platform/arch — and transmits it to two attacker-controlled collectors: (1) a DNS lookup whose label is the hex-encoded hostname under a canarytokens.com subdomain, and (2) an HTTPS GET to https://eolxuw8fddeyjj8.m.pipedream.net carrying the collected fields as query parameters. The callback wraps all I/O in try/catch and forces process.exitCode=0, so the install completes silently even if the network call fails, hiding the beacon from the installer. The package self-describes as a dependency-confusion proof-of-concept, but the behavior is genuine install-time exfiltration of installer-identifying data and harms any machine that runs npm install.
