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 browser publisher routes npm bearer credentials and selected package contents to a third-party Worker in normal web use. A credential is embedded in the page. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-14T03:43:01.042Z - **Finished:** 2026-09-14T03:43:55.875Z - **Download time:** 766 ms - **Static scan time:** 14 ms - **AI review time:** 54053 ms - **Total time:** 54833 ms The recorded confidence comes from the underlying analysis.

A credential is embedded in the page. - **Trigger:** Open index.html and click Publish Link with a selected file. - **Impact:** The Worker operator can receive npm credentials and uploaded package data, enabling account or package compromise. - **Evidence paths:** app.js, index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-14T03:43:55.875Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Credential and file upload exfiltration through a Worker proxy. - **Attack narrative:** The page includes an npm credential and, on a user-initiated publish action, packages the selected file or archive entries into a JSON payload. In ordinary browser mode it sends that payload and the bearer token to a third-party Cloudflare Worker rather than directly to npm. This exposes credentials and package contents to the Worker operator. - **Rationale:** The explicit click does not neutralize the embedded credential or the non-npm proxy receiving both the bearer token and upload data. This is concrete credential and data exfiltration behavior. - **Files touched:** user-selected upload file, zip archive entries - **Network endpoints:** https://dawn-salad-6ee1.vihaanb0715.workers.dev, https://registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The HTML embeds an npm credential in the token input., Browser publishing sends the bearer token to a non-npm Worker endpoint., Selected upload contents are base64-attached and sent with the request., The page embeds an npm authentication token as the password input’s default value. - **Evidence against:** package.json has no install lifecycle hook., The network action requires a user clicking the publish button. ## Affected versions and remediation This report applies to @vbansal67/npm-is-tuff-bruh@1.0.0. - Avoid installing @vbansal67/npm-is-tuff-bruh@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.
