Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Importing the package runs browser-side requests without user interaction. It collects a same-origin profile response and document cookie, then transmits both to an external webhook. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-18T13:56:40.951Z - **Finished:** 2026-09-18T13:57:11.818Z - **Download time:** 511 ms - **Static scan time:** 6 ms - **AI review time:** 30349 ms - **Total time:** 30867 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:** Importing the package runs browser-side requests without user interaction. It collects a same-origin profile response and document cookie, then transmits both to an external webhook. - **Trigger:** Importing or loading the package entry point in a browser-like environment. - **Impact:** Session-related cookie data and profile content can be disclosed to a third party. - **Evidence paths:** index.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-18T13:57:11.818Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Cookie and profile-response exfiltration through fetch. - **Attack narrative:** The package entry point runs immediately on import. It requests /profile, reads the response text and document.cookie, URL-encodes both values, and sends them to a webhook.site URL controlled outside the application. This is direct browser data exfiltration. - **Rationale:** The package contains concrete import-time collection and external transmission of browser cookie and profile data. The absence of lifecycle hooks does not mitigate this runtime exfiltration behavior. - **Files touched:** index.js - **Network endpoints:** /profile, webhook.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The main entry immediately fetches /profile and sends its response and browser cookie to a webhook.site endpoint., The manifest declares index.js as the package entry point, so importing the package activates this code. - **Evidence against:** No npm lifecycle scripts are declared., No shell execution, file writes, or persistence code was found in the two-package-file snapshot. ## Affected versions and remediation This report applies to pulse-pwn-9f3a2@1.0.0. - Avoid installing pulse-pwn-9f3a2@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.
