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 package's only entrypoint is an obfuscated browser challenge page that contacts a concealed endpoint and redirects the visitor. This is unrelated to a normal npm package runtime. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-22T00:18:49.793Z - **Finished:** 2026-09-22T00:27:41.048Z - **Download time:** 507 ms - **Static scan time:** 37 ms - **AI review time:** 530710 ms - **Total time:** 531255 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 package's only entrypoint is an obfuscated browser challenge page that contacts a concealed endpoint and redirects the visitor. This is unrelated to a normal npm package runtime. - **Trigger:** Loading index.html or importing the declared main entrypoint in a browser context. - **Impact:** Visitors can be routed through a deceptive challenge to an undisclosed remote destination. - **Evidence paths:** package.json, index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-22T00:27:41.048Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It loads Turnstile, posts a concealed host key through fetch, and invokes redirectToHost after the challenge or a timeout. - **Attack narrative:** The package presents a Cloudflare-style challenge while hiding its operational logic in a large obfuscated script. On load, it uses a concealed key in a remote request and automatically calls a redirect routine after the challenge or timeout. The undisclosed destination and deceptive browser flow create a concrete phishing or traffic-redirection capability. - **Rationale:** The sole npm entrypoint is an obfuscated remote challenge-and-redirect page, not package functionality. Its concealed request and automatic redirect constitute concrete malicious behavior. - **Network endpoints:** https://challenges.cloudflare.com, https://challenges.cloudflare.com/turnstile/v0/api.js ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package declares an HTML page as its only runtime entrypoint., The entrypoint loads Cloudflare Turnstile and invokes a hidden challenge-redirect callback after completion., Obfuscated code sends a JSON request containing a concealed host key, then schedules a redirect function automatically., The runtime is deliberately heavily obfuscated, concealing its endpoint selection and redirect logic. - **Evidence against:** No npm lifecycle hook or filesystem mutation was found in package.json., No direct credential or local-file harvesting primitive was identified in the inspected entrypoint. ## Affected versions and remediation This report applies to lufxchwmxwyps@1.0.2. - Avoid installing lufxchwmxwyps@1.0.2. 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.
