Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Installation metadata is disclosed to a third-party analytics service without an affirmative opt-in. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 1.7.1 - **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: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package's install dependency chain activates default-on analytics that transmits installation metadata to scarf.sh without affirmative installer consent. This is an automatic installation disclosure, so I classify it as malicious data exfiltration under the installation beacon policy. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-21T14:22:37.265Z - **Finished:** 2026-10-21T14:24:08.661Z - **Download time:** 1514 ms - **Static scan time:** 20 ms - **AI review time:** 89861 ms - **Total time:** 91396 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:** Scarf's install hook sends installation and dependency metadata to its analytics service by default. The reporter permits opting out but does not require affirmative consent before sending. - **Trigger:** Installing the package with npm when analytics has not been explicitly disabled. - **Impact:** Installation metadata is disclosed to a third-party analytics service without an affirmative opt-in. - **Evidence paths:** package.json, .lpm-dependency-evidence-33d84252-0d08-4fe4-b0cf-967eaacfefe9/2/npm-linux/package.json, .lpm-dependency-evidence-33d84252-0d08-4fe4-b0cf-967eaacfefe9/2/npm-linux/report.js - **Review source:** ai\_review - **Reviewed:** 2026-10-21T14:24:08.661Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The Scarf postinstall reporter gathers platform, architecture, Node version, and dependency metadata, then posts it to scarf.sh. - **Attack narrative:** During installation, Scarf runs its postinstall reporter. The reporter defaults to opted in, builds an installation metadata payload, and sends it to scarf.sh unless the installer opts out; its notice does not require a yes before sending. - **Rationale:** The package's install dependency chain activates default-on analytics that transmits installation metadata to scarf.sh without affirmative installer consent. This is an automatic installation disclosure, so I classify it as malicious data exfiltration under the installation beacon policy. - **Files touched:** package.json, .lpm-dependency-evidence-33d84252-0d08-4fe4-b0cf-967eaacfefe9/2/npm-linux/package.json, .lpm-dependency-evidence-33d84252-0d08-4fe4-b0cf-967eaacfefe9/2/npm-linux/report.js - **Network endpoints:** scarf.sh ### Review decision - **Verdict:** Malicious - **Confidence:** 88.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json declares Scarf as a runtime dependency, and Scarf's manifest runs its reporter during postinstall., The reporter defaults to opted in; it proceeds unless the installer has opted out, without requiring an affirmative response., The reporter builds an install payload containing platform, architecture, Node version, and dependency metadata., The reporter selects scarf.sh and sends the payload in an HTTPS request. ## Affected versions and remediation This report applies to @reboot-dev/reboot-std@1.7.1. - Avoid installing @reboot-dev/reboot-std@1.7.1. 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.
