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. The package's main module steals browser session-related data and authenticated profile content. It sends the collected data to a third-party webhook. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-18T13:55:08.701Z - **Finished:** 2026-09-18T13:55:37.346Z - **Download time:** 511 ms - **Static scan time:** 7 ms - **AI review time:** 28127 ms - **Total time:** 28645 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 main module steals browser session-related data and authenticated profile content. It sends the collected data to a third-party webhook. - **Trigger:** Importing or otherwise loading the package main module in a browser-like environment. - **Impact:** Cookies, page content, and authenticated profile data may be exposed to the webhook operator. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-18T13:55:37.346Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Immediate browser data collection followed by webhook exfiltration. - **Attack narrative:** When the configured main module loads, its immediately invoked function reads document.cookie and up to 1,500 characters of the page body. It also requests /profile with included credentials. Both records are posted through sendBeacon or fetch to a fixed webhook.site URL, exposing browser and account data without user action. - **Rationale:** This is concrete, automatic credential and application-data exfiltration from the package entry point. The fixed external receiver and immediate execution establish malicious behavior. - **Files touched:** index.js - **Network endpoints:** https://webhook.site/c4e39647-bfb8-47ef-b6d4-a112aacc6cd1, /profile ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The main entry point immediately collects browser cookies and page HTML, then sends them to a fixed webhook., It also fetches the authenticated local /profile endpoint and exfiltrates its response to the same webhook., Importing the configured main file triggers this code without an exported or user-invoked function. ## Affected versions and remediation This report applies to pf23727@1.0.0. - Avoid installing pf23727@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.
