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. A preinstall hook exfiltrates host and user installation metadata without a user command. It uses DNS and HTTP(S), including a raw IP address. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-07T08:17:49.294Z - **Finished:** 2026-09-07T08:18:31.112Z - **Download time:** 765 ms - **Static scan time:** 18 ms - **AI review time:** 41035 ms - **Total time:** 41818 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:** A preinstall hook exfiltrates host and user installation metadata without a user command. It uses DNS and HTTP(S), including a raw IP address. - **Trigger:** Installing the package with npm lifecycle scripts enabled. - **Impact:** Leaks identifying machine, user, directory, and package-manager metadata to external hosts. - **Evidence paths:** package.json, preinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T08:18:31.112Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time collection and DNS/HTTP beaconing. - **Attack narrative:** npm runs preinstall.js during installation. The script collects the username, hostname, working and install directories, platform, Node version, and npm metadata. It sends hostname and username through DNS and posts the full JSON object to an OAST host and a raw IP address, with HTTPS-to-HTTP fallback. This is unconsented install-time data exfiltration. - **Rationale:** The package performs concrete, automatic collection and external transmission during preinstall. Its research-oriented claims do not establish consent for exfiltration in downstream installations. - **Files touched:** preinstall.js - **Network endpoints:** dae7n4pijsh1ahi9684gu8get3kaiefc9.oast.online, 5.189.159.252 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Installation automatically runs preinstall.js., The install hook collects the local username, hostname, working directory, install path, platform, Node version, and npm metadata., It encodes hostname and username into a DNS lookup and posts the collected JSON to two external destinations., The hook falls back from HTTPS to plain HTTP, increasing exposure of the collected data. - **Evidence against:** The source does not read project files, spawn commands, or create persistence. ## Affected versions and remediation This report applies to @caliperx2/components@9999.0.0. - Avoid installing @caliperx2/components@9999.0.0. 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.
