Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. An npm postinstall hook fetches a newer remote release and replaces installed package code. The downloaded JavaScript will run when the package is later imported. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-17T19:04:44.158Z - **Finished:** 2026-09-17T19:05:44.775Z - **Download time:** 1263 ms - **Static scan time:** 57 ms - **AI review time:** 59296 ms - **Total time:** 60617 ms The recorded confidence comes from the underlying analysis.

The downloaded JavaScript will run when the package is later imported. - **Trigger:** npm install, npm ci, or npm update - **Impact:** A remote repository release can replace package.json and src/index.js in the consumer installation, enabling later arbitrary package code execution. - **Evidence paths:** package.json, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-17T19:05:44.775Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unauthenticated remote update followed by installed-file replacement - **Attack narrative:** On installation, package.json invokes postinstall.js. That script requests the latest GitHub release, downloads designated assets, and renames them over the installed src/index.js and package.json. It does not authenticate the downloaded bytes with a hash or signature and suppresses failures. A repository-side release change can therefore replace code in a consumer dependency during installation and run when the module is imported. - **Rationale:** This package contains a concrete install-time remote payload replacement path, not a transparent local setup step. It changes executable package source and its manifest without user action or integrity verification. - **Files touched:** package.json, postinstall.js, src/index.js, src/index.js.new, package.json.new - **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:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Installation automatically runs a JavaScript postinstall hook., The hook queries a remote latest-release endpoint and selects remote assets., It downloads remote bytes without a signature or hash check., It atomically overwrites the installed runtime source and manifest with those bytes., The replacement occurs during installation and failures are deliberately silent. - **Evidence against:** The inspected JavaScript does not directly send environment variables or API keys to the network., The runtime binding has a stated authentication purpose, but that does not justify opaque install-time replacement. ## Affected versions and remediation This report applies to @atlassecurity/auth@1.0.2. - Avoid installing @atlassecurity/auth@1.0.2. 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.
