Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to @k18n/creatormarketplace-admin-language@99.0.2. The same advisory and Firewall decision cover these 3 recorded versions: 99.0.0, 99.0.1, 99.0.2. - Avoid installing @k18n/creatormarketplace-admin-language@99.0.2. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% 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. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** @k18n/creatormarketplace-admin-language - **Ecosystem:** npm - **Version:** 99.0.2 - **License:** ISC - **Version published:** 2026-06-28T02:45:33.735Z - **Package first seen:** 2026-07-08T17:25:10.588Z - **Package last seen:** 2026-07-08T17:25:10.588Z - **Known versions:** 3 - **Latest version:** 99.0.2 - **Appeal under review:** No - **Description:** Security research - dependency confusion proof of concept. This package demonstrates that the @k18n npm scope was unclaimed while being used internally by Kuaishou.
