That script can execute automatically during dependency installation. - **Trigger:** npm installation of kepler - **Impact:** Remote publisher-controlled code execution on the installer host. - **Evidence paths:** package.json, npm-shrinkwrap.json, index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-30T17:14:42.196Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote dependency install-script execution - **Attack narrative:** The manifest redirects dependency resolution to artifacts.yosiroute.com rather than a normal registry package. Its shrinkwrap declares the fetched package has an install script, so npm installation can execute remote-controlled code not included in this package for review. The high published version also conflicts with the embedded 1.0.0 metadata. - **Rationale:** The package is a minimal carrier for an unauditable remote dependency that automatically executes installation code. Static exports are benign but do not mitigate the install-time execution path. - **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:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json pins dependency to a non-registry URL., npm-shrinkwrap.json marks that remote dependency hasInstallScript., The remote dependency has no integrity hash or bundled source to audit., Manifest/package sources disagree on version (5.999.999 vs 1.0.0). - **Evidence against:** index.js only exports static name and version., No direct lifecycle script or network code exists in package files. ## Public findings ### 1.
