Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The remote \`c.vipersfutbol.com\` script runs with the page's origin privileges; the embedded proxy stack can process routed browser traffic and cookie state. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 2.0.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Direct source inspection confirms automatic remote code loading and a browser proxy/service-worker stack that handles routed requests and cookies. There is no npm lifecycle execution, but the concrete runtime attack surface warrants blocking this package artifact. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-07-10T18:14:30.146Z - **Finished:** 2026-07-10T18:16:03.217Z - **Download time:** 513 ms - **Static scan time:** 2864 ms - **AI review time:** 89694 ms - **Total time:** 93071 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 main entry automatically imports a third-party remote script and local proxy/service-worker components. The local controller can intercept browser requests and exchange request metadata and cookies across its proxy context. - **Trigger:** A user opens or serves \`index.html\` in a browser. - **Impact:** The remote \`c.vipersfutbol.com\` script runs with the page's origin privileges; the embedded proxy stack can process routed browser traffic and cookie state. - **Evidence paths:** index.html, bfjdx/757lr8.js, ct1tl/pap3do.js, ct1tl/csbzam.js, ct1tl/jmqwjq.js, j6k3y8.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-07-10T18:16:03.217Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote script execution plus browser request/cookie interception. - **Attack narrative:** The package is presented as an npm artifact but its \`main\` is a browser page. On page load it executes a script from an unrelated third-party domain and loads local Scramjet proxy code. The bundled service-worker/controller path claims clients, conditionally intercepts fetches, and passes request URLs, headers, bodies, and cookie updates through its RPC layer. This establishes a concrete runtime web-control surface whose remote script can be changed outside the package, although there is no install-time execution. - **Rationale:** Direct source inspection confirms automatic remote code loading and a browser proxy/service-worker stack that handles routed requests and cookies. There is no npm lifecycle execution, but the concrete runtime attack surface warrants blocking this package artifact. - **Files touched:** index.html, bfjdx/757lr8.js, ct1tl/pap3do.js, ct1tl/csbzam.js, ct1tl/jmqwjq.js, j6k3y8.js, package.json - **Network endpoints:** https://c.vipersfutbol.com/script.js, https://www.googletagmanager.com/gtag/js?id=G-0VL3ZSBXDH ### Review decision - **Verdict:** Malicious - **Confidence:** 90.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** \`index.html\` executes \`https://c.vipersfutbol.com/script.js\` automatically when opened., \`index.html\` loads opaque \`bfjdx/757lr8.js\` and \`ct1tl/pap3do.js\` before the app bundle., \`j6k3y8.js\` installs a service worker that claims clients and routes matching requests., \`ct1tl/jmqwjq.js\` forwards intercepted requests, headers, bodies, and cookies through a controller RPC., \`ct1tl/csbzam.js\` injects the Scramjet client and exchanges cookies with the service worker. - **Evidence against:** \`package.json\` contains no \`scripts\`, lifecycle hook, or \`bin\` entry., The browser control surface is activated only by opening \`index.html\`, not npm installation., \`bfjdx/757lr8.js\`/\`ct1tl/\*\` appear to implement a web-proxy framework; no fixed exfiltration host was found in those sources. ## Affected versions and remediation This report applies to crazynut@2.0.0. - Avoid installing crazynut@2.0.0. 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.
