Summary

Malicious code in @k18n/creatormarketplace-admin-language (npm)

Details

Package claims the @k18n npm scope (used internally by Kuaishou) and publishes at version 99.0.0 — the canonical high-version dependency-confusion shape that causes internal builds resolving @k18n from public npm to pull this artifact. A preinstall script in index.js collects host identifiers (os.hostname(), os.userInfo().username, install directory, cwd, package version) and transmits them to c.adityasec.com over two channels: an HTTPS POST to https://c.adityasec.com/LdCdrTByhmflbwt5qFNisg and a DNS lookup of a hex-encoded subdomain under c.adityasec.com (DNS exfil fallback for hosts where outbound HTTPS is restricted). The lifecycle hook fires automatically on `npm install` with no consent. The package's own description self-labels this as a 'dependency confusion proof of concept,' but the cover-story label does not change the installer-side harm: any build host that resolves @k18n from the public registry leaks internal hostnames, usernames, and build paths to a third-party operator.
