Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.6.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The package exposes a Prefactor CLI and has no install lifecycle hook. The inspected downloads, API requests, and platform check are consistent with CLI functionality and do not show automatic data collection or unrelated execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-31T22:57:31.910Z - **Finished:** 2026-10-31T22:57:59.301Z - **Download time:** 772 ms - **Static scan time:** 2303 ms - **AI review time:** 24315 ms - **Total time:** 27391 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:** No attack was identified in the inspected package source. - **Trigger:** CLI network and installation operations are initiated by user-run commands; package.json declares no lifecycle scripts. - **Impact:** No automatic credential collection, unrelated data transfer, or malicious execution was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-31T22:57:59.301Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer fetches the CLI’s own release assets from GitHub, and API requests use the configured Prefactor service URL and user-selected credentials. - **Rationale:** The package exposes a Prefactor CLI and has no install lifecycle hook. The inspected downloads, API requests, and platform check are consistent with CLI functionality and do not show automatic data collection or unrelated execution. - **Files touched:** $HOME/.prefactor (installer target) - **Network endpoints:** https://github.com/prefactordev/typescript-sdk/releases/download, https://app.prefactorai.com ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest identifies this as Prefactor’s CLI and exposes its library and CLI entry points; it declares no lifecycle scripts., The installer downloads release assets from the Prefactor GitHub releases host, unless the user configures an override., Downloaded assets are fetched by the installer’s explicit download routine; review found no install hook that invokes it automatically., The CLI’s \`ping\` command sends a supplied or selected API token to the configured Prefactor API URL when the user runs that command., Platform detection runs \`sysctl\` only to check whether macOS is under Rosetta translation. - **Evidence against:** The package uses network, filesystem, and child-process capabilities for CLI functions such as API requests and installing or updating its own binary., The scan’s reported dangerous delta is not supported by evidence of automatic malicious behavior in the inspected entry points and installer. ## Affected versions and remediation This report applies to @prefactor/cli@0.6.1. - Review the evidence and your use of @prefactor/cli@0.6.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
