No install-time attack surface was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 92.0% - **Started:** 2026-07-15T08:54:11.509Z - **Finished:** 2026-07-15T08:56:47.126Z - **Download time:** 505 ms - **Static scan time:** 1097 ms - **AI review time:** 154014 ms - **Total time:** 155617 ms ## Security analysis ### Published attack-surface review - **Summary:** Runtime design-to-code tool use sends a persistent host/user fingerprint and conversion metadata to a third-party analytics endpoint. No install-time attack surface was found. - **Trigger:** User invokes Sloth MCP design-to-code tools or conversion flows. - **Impact:** Unconsented host/user metadata exfiltration during normal package use. - **Evidence paths:** dist/build/utils/tj.js, dist/build/index.js, package.json, cli/run.js - **Review source:** ai\_review - **Reviewed:** 2026-07-15T08:56:47.126Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unconditional analytics POST with machine and user identifiers. - **Rationale:** This is concrete runtime data exfiltration, but the inspected source does not establish a broader malicious chain such as credential theft, stealth persistence, remote payload execution, or install-time control-surface mutation. - **Files touched:** dist/build/utils/tj.js, dist/build/index.js, package.json, cli/run.js - **Network endpoints:** https://otheve.beacon.qq.com/analytics/v2\_upload?appkey=0WEB0IK7H05E5K4S ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for:** \`dist/build/utils/tj.js\` collects machine ID, hostname, OS, username/user ID., \`dist/build/utils/tj.js\` posts that fingerprint to \`otheve.beacon.qq.com\`., \`dist/build/index.js\` invokes telemetry during MCP tool/core conversion flows., \`isOnline\` is defined but not used to gate telemetry in \`dist/build/utils/tj.js\`. - **Evidence against:** \`package.json\` has no preinstall/install/postinstall lifecycle hook., No credential-file harvesting or remote code execution was found in reviewed telemetry paths., Child-process usage in \`cli/run.js\` is tied to explicit server/install/update commands. ## Public findings ### 1.
