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 stated placeholder purpose does not require automatic external telemetry. Its postinstall beacon exfiltrates host-derived data through both HTTPS and DNS. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-08-14T13:03:18.099Z - **Finished:** 2026-08-14T13:03:59.950Z - **Download time:** 505 ms - **Static scan time:** 24 ms - **AI review time:** 41320 ms - **Total time:** 41851 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:** Installation automatically transmits host-derived telemetry to a third-party OAST endpoint. A DNS fallback leaks a hostname-derived label. - **Trigger:** npm install - **Impact:** Unconsented installation-context data exfiltration - **Evidence paths:** package.json, beacon.js, cli.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T13:03:59.950Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall HTTPS and DNS telemetry beacon - **Attack narrative:** On npm install, the package runs beacon.js. It builds telemetry containing hostname, platform, Node version, and CI status, then sends it to an OAST host over HTTPS; if that fails, it performs a DNS lookup with a hostname-derived subdomain. This is an unconsented install-time network exfiltration channel. - **Rationale:** The package's stated placeholder purpose does not require automatic external telemetry. Its postinstall beacon exfiltrates host-derived data through both HTTPS and DNS. - **Files touched:** package.json, beacon.js - **Network endpoints:** https://d9v7gkqgp7glpsfhspo0bnf169cgo7f97.oast.pro/canary, d9v7gkqgp7glpsfhspo0bnf169cgo7f97.oast.pro ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** postinstall executes beacon.js automatically., Beacon sends hostname, platform, Node version, and CI status to an external OAST host., DNS fallback embeds hostname-derived label in lookup. - **Evidence against:** CLI only displays a placeholder notice and exits., No file reads, shell execution, or payload loading found. ## Affected versions and remediation This report applies to atomic-meta-check@0.0.1. - Avoid installing atomic-meta-check@0.0.1. 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.
