Neither array is read anywhere in endpointmap's own code — index.js only exposes the registry object — and the bytes are opaque (XOR-shaped, with no key shipped in this package). At the same time, package.json declares `\"bytecraft\": \"*\"` as a dependency. endpointmap's source never `require`s bytecraft; the only effect of the declaration is to force installation of whatever `bytecraft@latest` happens to be at install time. The combination — staged encoded data in this package plus an unpinned, never-imported sibling that can be updated to act as the decoder/runtime — is the canonical 'data here, decoder there' split designed to evade per-package review. An installer of endpointmap is exposed to whatever bytecraft resolves to at install/require time, including future malicious versions, without endpointmap itself ever needing another release.\n\n## Source: ghsa-malware (7cf1ae7dc26d8ebda1199b5e88d8fb0d49e4db8f72ff01b5f2b0dea88cf4a8a0)\nAny computer that has this package installed or running should be considered fully compromised.
