Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. An automatic install hook discovers a matching consumer repository and reports it to a remote service. This is undisclosed install-time telemetry outside the package's stated public-statistics purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-07T09:16:03.575Z - **Finished:** 2026-09-07T09:16:41.851Z - **Download time:** 504 ms - **Static scan time:** 48 ms - **AI review time:** 37723 ms - **Total time:** 38276 ms The recorded confidence comes from the underlying analysis.

This is undisclosed install-time telemetry outside the package's stated public-statistics purpose. - **Trigger:** Installing the package through npm outside CI or global mode. - **Impact:** Exposes the consuming project's repository identity, GitHub URL, detection source, and installation time to a third party without an explicit user action. - **Evidence paths:** package.json, postinstall.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-09-07T09:16:41.851Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall repository discovery and remote telemetry beacon. - **Attack narrative:** When npm installs the package, its postinstall hook walks the consumer directory and up to seven parents. It invokes Git or reads .git/config, and also reads package manifests to identify Best Radar repositories. If it finds one, it sends the repository identity, GitHub URL, source of detection, package version, and timestamp to a Cloudflare Workers endpoint. Errors are suppressed, making the telemetry silent. The README instead presents the package as using public npm installation statistics. - **Rationale:** This package contains a silent, automatic install-time telemetry beacon that inspects consumer project metadata and transmits it to a third party without an explicit user command. The vendor-name filter limits scope but does not make the unadvertised data collection consented. - **Files touched:** postinstall.js, package.json, .git/config - **Network endpoints:** https://bradar-cloud-bridge.bestradar.workers.dev/install-ping ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs postinstall.js automatically during npm installation., The installer searches the consuming project and parent directories, including Git configuration and package manifests, to identify repositories., The install hook silently sends the detected repository identity and install metadata to a third-party endpoint., The README advertises public npm statistics, while the source implements an undisclosed install-time network beacon. - **Evidence against:** The beacon limits reporting to repositories matching the Best Radar naming pattern., The inspected code does not read credentials, write files, download code, or execute remote payloads. ## Affected versions and remediation This report applies to best-radar-pulse@1.0.3. - Avoid installing best-radar-pulse@1.0.3. 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.
