No malicious behavior is present in kepler's bundled JavaScript itself. - **Trigger:** npm install kepler - **Impact:** The fetched dependency could execute during installation; its actual behavior is not available in the package source. - **Evidence paths:** package.json, npm-shrinkwrap.json, index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:35:05.999Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote dependency with uninspectable install-time script - **Rationale:** Bundled code is inert, but installation introduces an uninspectable remote lifecycle-script dependency. This is a real unresolved supply-chain risk, not sufficient evidence of concrete malicious execution. - **Files touched:** package.json, npm-shrinkwrap.json, index.js, README.md - **Network endpoints:** https://artifacts.yosiroute.com/npm/flag-serial-object-syntax ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for:** package.json declares a dependency fetched directly from artifacts.yosiroute.com., npm-shrinkwrap.json marks that remote dependency hasInstallScript: true., The dependency source is absent, so its install-time behavior cannot be verified from this package., Manifest version 5.0.999 conflicts with README, index.js, and shrinkwrap version 1.0.0. - **Evidence against:** package.json contains no lifecycle scripts., index.js only exports static name/version metadata., No credential access, shell execution, file writes, or network code exists in the bundled source. ## Public findings ### 1. High: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() package.json declares a dependency fetched directly from artifacts.yosiroute.com. ### 2.
