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. On installation, the package harvests host, environment, and project configuration data and sends it to an external callback host. It also sends a DNS beacon containing encoded host and user data. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-08T21:38:13.619Z - **Finished:** 2026-09-08T21:38:55.123Z - **Download time:** 1015 ms - **Static scan time:** 25 ms - **AI review time:** 40463 ms - **Total time:** 41504 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:** On installation, the package harvests host, environment, and project configuration data and sends it to an external callback host. It also sends a DNS beacon containing encoded host and user data. - **Trigger:** npm postinstall during package installation - **Impact:** Environment secrets, internal infrastructure details, host identity, and .env or configuration-file contents may be disclosed. - **Evidence paths:** package.json, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T21:38:55.123Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time credential and project-file exfiltration over HTTPS and DNS - **Attack narrative:** npm invokes postinstall.js automatically. The hook gathers host and user identity, reads operating-system network files, filters environment variables for likely secrets, walks parent directories for .env and configuration files, and sends the collected data to akko.requestcatcher.com. It also issues a DNS lookup encoding host and user data. - **Rationale:** This is concrete, unconsented install-time collection and exfiltration of credentials and project data. The harmless research framing does not match the implemented behavior. - **Files touched:** postinstall.js, package.json, .env, .env.local, .env.production, .env.development, config.js, config.json, config/database.yml, /etc/hostname, /etc/hosts, /etc/resolv.conf - **Network endpoints:** akko.requestcatcher.com, dep.\.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 when npm installs it., The install hook sends encoded payloads to akko.requestcatcher.com., The hook collects host and user identifiers and emits a DNS beacon., It selects environment variables likely to contain credentials or infrastructure details., It searches parent project directories for .env and configuration files, reads them, and transmits their contents., Comments framing this as harmless security research conflict with the credential and file collection behavior. - **Evidence against:** The runtime index exports only inert analytics-shaped functions., No destructive filesystem operation or child-process execution was found. ## Affected versions and remediation This report applies to @umschool/analytics@999.0.4. - Avoid installing @umschool/analytics@999.0.4. 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.
