AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Direct source inspection contradicts the clean hint: the package ships an obfuscated fake-CAPTCHA redirect page as its main entrypoint. Although it has no install hook, the user-invoked browser payload is concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-08-11T17:48:03.192Z - **Finished:** 2026-08-11T17:49:46.680Z - **Download time:** 508 ms - **Static scan time:** 9 ms - **AI review time:** 102970 ms - **Total time:** 103488 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:** Opening the package entrypoint shows a fake security-verification page and redirects the browser to an obfuscated destination. Query parameters are propagated to that destination. - **Trigger:** A user opens index.html and the Turnstile callback fires. - **Impact:** Potential phishing or tracking redirect to a concealed remote site. - **Evidence paths:** package.json, index.html - **Review source:** ai\_review - **Reviewed:** 2026-08-11T17:49:46.680Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated query-preserving browser redirect behind a fake CAPTCHA. - **Attack narrative:** The only packaged entrypoint is a fake Cloudflare verification page. On its callback, obfuscated JavaScript builds a concealed URL, copies the current page's query parameters into it, and redirects with window.location.replace. This has no legitimate npm-package function and creates a concrete browser-phishing/redirect surface. - **Rationale:** Direct source inspection contradicts the clean hint: the package ships an obfuscated fake-CAPTCHA redirect page as its main entrypoint. Although it has no install hook, the user-invoked browser payload is concrete malicious behavior. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com/turnstile/v0/api.js ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.html is the manifest main entrypoint., index.html presents a Cloudflare-style Turnstile challenge., Its completion/error callbacks enter heavily obfuscated code., The code constructs an obfuscated URL, copies page query parameters, then calls window.location.replace(). - **Evidence against:** package.json has no lifecycle scripts., No Node filesystem, process, or child-process APIs are present. ## Affected versions and remediation This report applies to twcvhjlksdmx@1.0.0. - Avoid installing twcvhjlksdmx@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.
