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 published main file runs on import: it reads a flag-like value from /profile and POSTs it to /addPost. That is scrape-and-exfiltrate behavior, not a feed widget. There is no install-time hook. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-09-17T02:21:08.350Z - **Finished:** 2026-09-17T02:22:36.366Z - **Download time:** 509 ms - **Static scan time:** 6 ms - **AI review time:** 87500 ms - **Total time:** 88016 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:** The published main file runs on import: it reads a flag-like value from /profile and POSTs it to /addPost. That is scrape-and-exfiltrate behavior, not a feed widget. There is no install-time hook. - **Trigger:** Importing or bundling index.js, especially in a browser on a site that serves /profile and /addPost. - **Impact:** Profile page content is copied into a new post on the same origin. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-17T02:22:36.366Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time scrape of profile HTML and POST of the flag text - **Attack narrative:** When this module is imported or bundled, it immediately requests /profile, parses a .flag-value node, and POSTs that text to /addPost. The package does not export a helper API, and the name feed-widget-helper does not match this behavior. In a browser on a site that has those routes, that leaks profile content into a new post. There are no install lifecycle scripts, but the main entry is itself the payload. - **Rationale:** index.js is an import-time scrape-and-post payload that copies .flag-value from /profile to /addPost, which does not match a feed widget helper. That is concrete data theft even though there are no install hooks or third-party hosts. - **Network endpoints:** /profile, /addPost ### Review decision - **Verdict:** Malicious - **Confidence:** 92.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js has no exports and immediately GET-fetches /profile when the module loads, It parses a .flag-value node from that HTML and POSTs the text to /addPost, The package is named a feed widget helper but has empty metadata and no widget API - **Evidence against:** package.json has only a test script and no preinstall, install, or postinstall hooks, Fetches use same-origin relative paths, not a hardcoded third-party host, No child\_process, eval, filesystem, or environment-variable access ## Affected versions and remediation This report applies to feed-widget-helper@1.0.4. - Avoid installing feed-widget-helper@1.0.4. 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.
