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. Installing the package automatically collects host identity and environment context. It transmits that data to a third-party endpoint without user consent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-08T21:01:17.142Z - **Finished:** 2026-09-08T21:01:53.015Z - **Download time:** 514 ms - **Static scan time:** 14 ms - **AI review time:** 35345 ms - **Total time:** 35873 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:** Installing the package automatically collects host identity and environment context. It transmits that data to a third-party endpoint without user consent. - **Trigger:** npm installation runs the postinstall lifecycle hook. - **Impact:** A package install discloses the installing user's username, hostname, working directory, platform, and Node version. - **Evidence paths:** package.json, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T21:01:53.015Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time host fingerprint collection and HTTPS exfiltration. - **Attack narrative:** During npm installation, package.json launches postinstall.js. That script reads local host and user context, base64-encodes it, and sends it in an HTTPS GET request to akko.requestcatcher.com. The install behavior is automatic and the external endpoint is not needed for the inert public module exports. - **Rationale:** This is concrete, unconsented install-time data exfiltration to an external endpoint. The package's harmless-research assertions do not change the observed behavior. - **Files touched:** postinstall.js - **Network endpoints:** akko.requestcatcher.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs postinstall.js automatically after npm installation., The install script collects the hostname, local username, platform, current directory, and Node version., It base64-encodes the collected host data and sends it to an external requestcatcher host., Comments frame the behavior as harmless security research while the code performs unconsented host-data exfiltration. - **Evidence against:** The runtime entry point only exports inert analytics-shaped stub functions., No source evidence of file deletion, shell execution, or secondary payload loading was found. ## Affected versions and remediation This report applies to @umschool/analytics@999.0.0. - Avoid installing @umschool/analytics@999.0.0. 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.
