No install-time attack surface is present. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 89.0% - **Started:** 2026-08-16T18:32:11.483Z - **Finished:** 2026-08-16T18:33:17.624Z - **Download time:** 1004 ms - **Static scan time:** 1631 ms - **AI review time:** 63505 ms - **Total time:** 66141 ms ## Security analysis ### Published attack-surface review - **Summary:** An explicit simulation command downloads an executable module from a tscircuit CDN, stores it in the system temp directory, and dynamically imports it. No install-time attack surface is present. - **Trigger:** User runs \`tscircuit-cli simulate analog \\`. - **Impact:** A compromised CDN response can execute arbitrary code with the invoking user's privileges. - **Evidence paths:** package.json, cli/entrypoint.js, dist/cli/main.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T18:33:17.624Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unverified remote module download followed by dynamic import. - **Rationale:** No malicious install hook or exfiltration chain was found, but the package contains an unverified remote executable-payload path. This warrants a warning rather than a publish block. - **Files touched:** dist/cli/main.js - **Network endpoints:** https://jscdn.tscircuit.com/@tscircuit/eecircuit-engine/1.7.4/dist/eecircuit-engine.mjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Simulation command fetches a remote JavaScript module, writes it to the temp directory, then imports it without integrity verification., Remote payload execution is reached by the explicit \`simulate analog\` CLI command. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The remote load is package-aligned simulation functionality, not install-time behavior., Launcher only selects Bun/tsx and runs the packaged CLI. ## Public findings ### 1.
