Description

Malicious code in @wbnr/design (npm)

Source: amazon-inspector

The package's preinstall lifecycle script runs automatically on npm install. It reads the installer's username (from USER/USERNAME environment variables) and the machine hostname (via os.hostname()), then embeds those identifiers along with the package name and a timestamp into both a DNS lookup and an HTTPS GET request directed at a hardcoded Burp Collaborator subdomain, 4otph6fase1x2won0hrfzul2wt2qqge5.oastify.com. The package name and scope (@wbnr) and its self-description indicate a dependency-confusion payload targeting an internal organization scope; any environment that resolves @wbnr/design from public npm will leak installer host identifiers to the attacker-controlled out-of-band endpoint. The 'harmless bug bounty PoC' framing in the package description does not change the observable behavior: installer-owned identifiers leave the machine to a third-party OOB collector on install.
