AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. This package contains no legitimate library implementation; its sole runtime artifact is an obfuscated, server-controlled redirect flow concealed behind a verification prompt. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-08-14T08:14:10.297Z - **Finished:** 2026-08-14T08:15:09.385Z - **Download time:** 764 ms - **Static scan time:** 25 ms - **AI review time:** 58298 ms - **Total time:** 59088 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's HTML entrypoint displays a fake security challenge. Completing it activates obfuscated code that obtains and decrypts a remote redirect target, then forwards browser query parameters. - **Trigger:** A user opens index.html and completes or errors the Turnstile challenge. - **Impact:** Can route victims, with URL parameters, to attacker-controlled content. - **Evidence paths:** index.html, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-14T08:15:09.385Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated server-controlled decrypted redirect behind a fake verification page. - **Attack narrative:** The sole package entrypoint is a Cloudflare-styled verification page. Its Turnstile callback runs heavily obfuscated code that POSTs to a concealed service, decrypts the response into a URL, appends the current page's query parameters, and redirects the browser. This is a concrete staged phishing/redirect chain rather than reusable package functionality. - **Rationale:** This package contains no legitimate library implementation; its sole runtime artifact is an obfuscated, server-controlled redirect flow concealed behind a verification prompt. - **Files touched:** index.html, package.json - **Network endpoints:** https://challenges.cloudflare.com/turnstile/v0/api.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Manifest exposes only an HTML page as the package entrypoint., The page impersonates a security-verification screen and invokes obfuscated logic after Turnstile completion., The callback POSTs to a concealed endpoint, decrypts a server-provided URL, copies current query parameters, and redirects the browser. - **Evidence against:** No npm lifecycle scripts are declared., No local filesystem, environment, or child-process access is present. ## Affected versions and remediation This report applies to @worrisome/reutil@1.0.2. - Avoid installing @worrisome/reutil@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.
