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 sole package entry is an obfuscated HTML page that retrieves, decrypts, and uses a remotely supplied URL. This is an active remote redirect mechanism with a concealed destination. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-29T07:52:01.117Z - **Finished:** 2026-09-29T07:53:06.966Z - **Download time:** 250 ms - **Static scan time:** 31 ms - **AI review time:** 65567 ms - **Total time:** 65849 ms The recorded confidence comes from the underlying analysis.

This is an active remote redirect mechanism with a concealed destination. - **Trigger:** Opening or rendering index.html. - **Impact:** Visitors can be sent to an operator-controlled destination that is not auditable from the published package. - **Evidence paths:** index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-29T07:53:06.966Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The embedded script performs a fetch request, decrypts the response into a URL, and drives an automatic redirect flow; Turnstile is loaded as part of the page. - **Attack narrative:** When the package entry is opened, its inline obfuscated script contacts an obscured endpoint, decrypts a returned URL, and automatically follows the resulting host flow. The destination is deliberately hidden from static inspection, while a Turnstile challenge is loaded to gate the page. This is a covert remote redirect loader rather than a normal npm package entry. - **Rationale:** The only entry point implements an obfuscated, remotely controlled redirect chain whose target is encrypted until runtime. That concealed active behavior is malicious. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package exposes index.html as its only main entry., The entry contains heavily obfuscated code that sends a JSON request with fetch., The response is decrypted and converted into a URL, then an automatic promise flow uses the resolved host URL., The page also loads a Cloudflare Turnstile script, consistent with gating the redirect flow. ## Affected versions and remediation This report applies to jxnbdyh8wpfhcb@1.0.0. - Avoid installing jxnbdyh8wpfhcb@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.
