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 fabric-asset-pipeline@1.0.0. The same advisory and Firewall decision cover these 2 recorded versions: 1.0.0, 1.0.1. - Avoid installing fabric-asset-pipeline@1.0.0. 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% fabric-asset-pipeline@1.0.0 declares a postinstall hook that runs index.js on npm install. index.js is heavily obfuscated (obfuscator.io-style rotated string array plus base64+RC4 decoding of identifiers and URLs, with newline/regex anti-formatting hooks) and implements a Minecraft credential stealer: functions stealLauncherAccounts(), stealAltLaunchers(), and readSessionDump() read account credential stores from the official Minecraft launcher (launcher\_accounts.json / launcher\_profiles.json) as well as Prism/MultiMC, TLauncher, Modrinth, PolyMC, and GDLauncher, plus a session dump from the OS temp directory. Extracted account names, access tokens, and refresh tokens are POSTed via https.request to a hardcoded webhook whose URL is RC4-decoded at runtime. A companion sendInfo() call ships os.hostname(), os.userInfo().username, os.platform()/os.release(), and the recovered Minecraft username to the same endpoint. None of this behavior is part of the package's advertised 'asset loader bridge' purpose, and the obfuscation deliberately conceals both the exfiltration functions and the destination URL. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** fabric-asset-pipeline - **Ecosystem:** npm - **Version:** 1.0.0 - **Version published:** 2026-09-28T16:29:39.217Z - **Package first seen:** 2026-09-28T18:40:06.061Z - **Package last seen:** 2026-09-28T18:40:06.061Z - **Known versions:** 2 - **Latest version:** 1.0.1 - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]()
