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 entrypoint harvests browser cookies and data from local application routes, then posts the results to an external webhook. It runs on import. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-18T13:55:08.508Z - **Finished:** 2026-09-18T13:55:37.915Z - **Download time:** 511 ms - **Static scan time:** 7 ms - **AI review time:** 28889 ms - **Total time:** 29407 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 entrypoint harvests browser cookies and data from local application routes, then posts the results to an external webhook. It runs on import. - **Trigger:** Loading or importing the package main entrypoint. - **Impact:** Cookies, route contents, HTTP statuses, and matching flag values can be disclosed to the webhook operator. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-18T13:55:37.915Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Browser data harvesting followed by external POST exfiltration. - **Attack narrative:** When the declared main file is imported in a browser-like environment, it reads document cookies, fetches ten local routes, extracts values matching a flag pattern, and POSTs the collected object to a fixed webhook.site URL. The behavior is automatic and has no legitimate exported interface or consent step. - **Rationale:** Source inspection confirms automatic credential and application-data collection with exfiltration to a fixed third-party endpoint. The lack of install hooks does not mitigate the malicious import-time behavior. - **Files touched:** index.js - **Network endpoints:** https://webhook.site/42c6d937-77c7-42a5-8678-ef06b4501e38 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The main entrypoint immediately reads browser cookies and sends collected data to a fixed webhook., It probes ten same-origin routes and extracts values matching a flag pattern from responses., Importing the declared main file activates the asynchronous collection routine without a user-facing API. - **Evidence against:** The manifest has no npm lifecycle scripts., No filesystem writes, shell commands, or persistence code were found. ## Affected versions and remediation This report applies to pflag14570@1.0.0. - Avoid installing pflag14570@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.
