Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Importing the module in a browser starts a two-second timer that reads an auth token or the full localStorage dump and POSTs it to /addPost. There is no other product behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-17T06:06:45.279Z - **Finished:** 2026-09-17T06:07:37.457Z - **Download time:** 511 ms - **Static scan time:** 5 ms - **AI review time:** 51661 ms - **Total time:** 52178 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Importing the module in a browser starts a two-second timer that reads an auth token or the full localStorage dump and POSTs it to /addPost. There is no other product behavior. - **Trigger:** Requiring or importing index.js in a page that has localStorage. - **Impact:** Session tokens and other client-stored secrets are sent to the host app /addPost endpoint, where they can be stored or leaked. - **Evidence paths:** index.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-17T06:07:37.457Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time localStorage token harvest and fetch POST - **Attack narrative:** analytics-widget@1.0.0 is a two-file package whose main entry runs immediately. After two seconds it pulls localStorage.getItem('token') or serializes all of localStorage, then fetch-POSTs that value to /addPost. That is credential theft on import, not an analytics widget. The relative URL still ships secrets off the page into whatever that endpoint records. - **Rationale:** Inspected source shows import-time localStorage token theft and a fetch POST with no legitimate widget code. That is concrete credential exfiltration, so the package is blocked. - **Network endpoints:** /addPost ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js runs a top-level setTimeout on import, not behind an exported API., It reads localStorage key token or stringifies the entire localStorage object., Stolen data is POSTed with fetch to /addPost as JSON content., The package name analytics-widget has no analytics behavior; main is this harvester. - **Evidence against:** package.json has no preinstall, install, or postinstall scripts., The fetch target is a same-origin relative path, not a hardcoded third-party host. ## Affected versions and remediation This report applies to analytics-widget@1.0.0. - Avoid installing analytics-widget@1.0.0. 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.
