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. A browser UI collects an npm token and a selected package file. In normal web use, it sends both to a non-npm worker host. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-14T03:44:29.759Z - **Finished:** 2026-09-14T03:45:25.480Z - **Download time:** 766 ms - **Static scan time:** 14 ms - **AI review time:** 54941 ms - **Total time:** 55721 ms The recorded confidence comes from the underlying analysis.

In normal web use, it sends both to a non-npm worker host. - **Trigger:** A user opens index.html, selects a file, and clicks Publish Link. - **Impact:** The worker can receive npm credentials and private package source, enabling account or package compromise. - **Evidence paths:** app.js, index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-14T03:45:25.480Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Bearer-token and package-upload relay to a third-party worker. - **Attack narrative:** The HTML entry point loads a publishing interface. After a user supplies an npm token and package file, app.js serializes the selected content and sends it with the bearer token. Browser execution routes this request to an opaque worker host rather than directly to npm, exposing the credential and package data to that host. - **Rationale:** This is concrete credential and source-data exfiltration through an opaque third-party relay. User interaction does not make forwarding an npm bearer token to that host safe. - **Files touched:** index.html, app.js - **Network endpoints:** https://dawn-salad-6ee1.vihaanb0715.workers.dev, https://registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The browser publisher sends an npm bearer token and uploaded package contents to a third-party worker., Normal browser use selects the worker endpoint instead of the npm registry., Uploaded ZIP entries are base64 encoded into attachments before the request., The page persists npm authentication tokens in browser local storage., The page embeds an npm authentication token as the default value of its token input. - **Evidence against:** There are no npm lifecycle hooks or install-time scripts., The network action requires a user to select a file and click the publish button. ## Affected versions and remediation This report applies to @vbansal67/npm-is-so-so-tuff@1.0.0. - Avoid installing @vbansal67/npm-is-so-so-tuff@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.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 95.0% - **Path:** index.html - **Public source:** [View source]() The page embeds an npm authentication token as the default value of its token input.
