AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Direct manifest inspection confirms two install-time scripts that fingerprint and exfiltrate the installer environment to an unrelated external callback domain. The empty runtime entrypoint does not mitigate this concrete lifecycle attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-13T20:34:08.600Z - **Finished:** 2026-08-13T20:34:46.249Z - **Download time:** 502 ms - **Static scan time:** 11 ms - **AI review time:** 37135 ms - **Total time:** 37649 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:** Automatic npm lifecycle scripts fingerprint the installer environment and transmit it to an external callback domain. Both preinstall and install perform the behavior without user action. - **Trigger:** npm preinstall/install lifecycle execution - **Impact:** Leaks installer username, hostname, working directory, and package identifier to an external operator. - **Evidence paths:** package.json, index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-13T20:34:46.249Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** base64-encoded host fingerprint exfiltration through HTTPS path and DNS query - **Attack narrative:** On installation, the package builds a base64 value containing \`whoami\`, hostname, current directory, and its package name. It places that value in an HTTPS request path and sends a second encoded package-derived value through DNS to callback.m0chan.co.uk. The duplicate preinstall and install hooks make this unconsented exfiltration automatic. - **Rationale:** Direct manifest inspection confirms two install-time scripts that fingerprint and exfiltrate the installer environment to an unrelated external callback domain. The empty runtime entrypoint does not mitigate this concrete lifecycle attack. - **Files touched:** package.json, index.js, README.md - **Network endpoints:** callback.m0chan.co.uk, https://$pkgsub.callback.m0chan.co.uk/$b64 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** \`preinstall\` collects username, hostname, working directory, and package name, then exfiltrates encoded data through HTTPS and DNS., \`install\` repeats the same automatic host-environment exfiltration. - **Evidence against:** \`index.js\` only exports an empty object; no additional runtime payload was found., README contains only a generic package description. ## Affected versions and remediation This report applies to @hzero-front-ui/c7n-ui@99.99.99. - Avoid installing @hzero-front-ui/c7n-ui@99.99.99. 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.
