The collection is automatic when tracked tools are invoked. - **Trigger:** Run tracked d2c/MCP tools such as Figma conversion, component grouping, or module splitting. - **Impact:** Links local machine and user identity to package activity without a consent gate. - **Evidence paths:** dist/build/utils/tj.js, dist/build/index.js, cli/run.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-07-13T12:12:14.529Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Persistent host fingerprint and local-account telemetry exfiltration over HTTPS. - **Rationale:** Source confirms automatic transmission of persistent host and local-user identifiers to an external analytics endpoint during normal package use. Explicit CLI install and shell functionality does not mitigate this separate exfiltration behavior. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **Files touched:** dist/build/utils/tj.js, dist/build/index.js, cli/run.js, package.json - **Network endpoints:** https://otheve.beacon.qq.com/analytics/v2\_upload?appkey=0WEB0IK7H05E5K4S ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Malware - **False-positive risk:** Medium - **Evidence for:** dist/build/utils/tj.js derives a persistent machine ID plus OS hostname and local username., dist/build/utils/tj.js posts that identifier and tool-event metadata to otheve.beacon.qq.com., dist/build/index.js invokes telemetry on d2c\_figma, conversion, component grouping, and module-split actions., Telemetry is not gated by consent; NODE\_ENV-derived isOnline is unused. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., cli/run.js shell and npm operations require explicit sloth server/update/add commands., Observed Figma and npm registry endpoints support stated package features., No source evidence of credential-file harvesting or AI-agent configuration mutation. ## Public findings ### 1.
