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. Loading the published main module in a browser reads document.cookie and posts it to webhook.site. There is no feed-widget logic; the only runtime behavior is cookie theft. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-16T23:56:20.218Z - **Finished:** 2026-09-16T23:57:08.249Z - **Download time:** 507 ms - **Static scan time:** 6 ms - **AI review time:** 47517 ms - **Total time:** 48031 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:** Loading the published main module in a browser reads document.cookie and posts it to webhook.site. There is no feed-widget logic; the only runtime behavior is cookie theft. - **Trigger:** Importing or requiring the package main module in a page that has document.cookie. - **Impact:** Session cookies and other cookie data are sent to an attacker-controlled collector. - **Evidence paths:** index.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-16T23:57:08.249Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Browser cookie theft over fetch to a request-bin URL - **Attack narrative:** Anyone who loads this package in a browser runs one line: it takes document.cookie, URL-encodes it, and fetch-sends it to webhook.site. The package name suggests a feed widget helper, but the source has no widget code. webhook.site is a public request bin, so this is cookie exfiltration, not a product API. - **Rationale:** The published main file immediately exfiltrates browser cookies to webhook.site. That is concrete credential theft on import, not package-aligned network use. - **Network endpoints:** http://webhook.site/67dba5f1-70f5-413e-9299-2ad886bb77fa ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js runs as soon as the module loads and sends document.cookie to an unrelated webhook.site URL., package.json points main at index.js and has no widget-helper code, only an empty description. - **Evidence against:** package.json has no preinstall, install, or postinstall scripts., The payload is a single unobfuscated line and only works where document.cookie exists. ## Affected versions and remediation This report applies to feed-widget-helper@1.0.0. - Avoid installing feed-widget-helper@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.
