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. When opened in a browser and the user presses Publish, the package sends an npm bearer token and selected package contents to a third-party worker. This can expose publishing credentials and private source files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-14T03:44:29.762Z - **Finished:** 2026-09-14T03:45:33.246Z - **Download time:** 762 ms - **Static scan time:** 14 ms - **AI review time:** 62707 ms - **Total time:** 63484 ms The recorded confidence comes from the underlying analysis.

This can expose publishing credentials and private source files. - **Trigger:** Opening index.html and clicking Publish after supplying a token and file. - **Impact:** An operator of the worker can obtain the token and uploaded package data, enabling unauthorized npm publishing or source disclosure. - **Evidence paths:** app.js, index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-14T03:45:33.246Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Third-party proxy upload carrying a bearer token and encoded file contents. - **Attack narrative:** The browser UI captures an npm token, saves it locally, encodes the chosen file or ZIP entries, and on Publish sends the payload with an Authorization bearer header. In ordinary browser use the target is a third-party worker rather than the npm registry, so that worker receives both the credential and package contents. The page also includes a prefilled credential-like token value. - **Rationale:** The source implements concrete credential and package-data transmission to an unrelated endpoint. User interaction is required, but it does not make forwarding an npm bearer token and archive contents to that endpoint safe. - **Files touched:** app.js, index.html - **Network endpoints:** https://dawn-salad-6ee1.vihaanb0715.workers.dev ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The page collects an npm authentication token and retains it in browser storage., On Publish, a browser-hosted run sends the bearer token to a third-party worker endpoint., It base64-encodes every non-excluded entry from the selected ZIP and includes it in that request., The HTML contains a prefilled npm-token value, exposing a credential-like secret., The page pre-fills an NPM Auth Token field with a credential-like npm token. - **Evidence against:** The manifest has no preinstall, install, or postinstall hook., The network request is triggered by the user clicking Publish, not by package installation. ## Affected versions and remediation This report applies to @vbansal67/npm-is-just-so-tuff@1.0.0. - Avoid installing @vbansal67/npm-is-just-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.
