A newer release can replace the installed JavaScript entrypoint and manifest without package-manager integrity controls. - **Trigger:** npm install, npm ci, or npm update - **Impact:** A remote release publisher can change code executed by consumers after installation while retaining a locally configured API key. - **Evidence paths:** package.json, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T04:09:41.265Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall remote payload download and atomic source replacement - **Attack narrative:** The package-manager postinstall hook queries a remote GitHub release. When its version is newer, it downloads remote assets and overwrites the installed entrypoint and package manifest. The downloaded code is not signed or hash-verified by the hook, and the hook preserves an existing API key while replacing the source. This creates an unconsented install-time remote code-update channel outside normal npm package integrity and review. - **Rationale:** This is a concrete install-hook supply-chain mechanism, not a normal transparent setup step. It remotely replaces executable package code and package metadata during installation. - **Files touched:** package.json, src/index.js, %LOCALAPPDATA%\\AtlasAuth\\dev\_marker.json - **Network endpoints:** https://api.github.com/repos/atlassecuritysolutions/AtlasAuthentication-JS/releases/latest, api.github.com, github.com, objects.githubusercontent.com, raw.githubusercontent.com, release-assets.githubusercontent.com ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs postinstall automatically., The install hook fetches a newer remote release and selects replacement source and manifest assets., The hook atomically overwrites its installed src/index.js and package.json with downloaded bytes., It reads and reinserts an existing API key into the downloaded source, preserving a secret-bearing local customization through the replacement. - **Evidence against:** The install hook only names GitHub-controlled asset hosts., No direct host-fingerprint upload or environment-value exfiltration appears in the inspected JavaScript. ## Public findings ### 1.
