Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Static inspection found an opaque detached child-process command in the launcher’s update path, alongside deliberate obfuscation in the published build. The inspected source does not establish a concrete attack, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 76.0% - **Started:** 2026-10-21T15:23:35.912Z - **Finished:** 2026-10-21T15:25:18.747Z - **Download time:** 1013 ms - **Static scan time:** 281 ms - **AI review time:** 101541 ms - **Total time:** 102835 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:** The launcher contains an update path that checks the npm registry and, when a newer release is available, starts a detached Node process with an obfuscated inline command. The command’s effect could not be resolved from the inspected source, so no concrete attack is established. - **Trigger:** Running the launcher when the registry reports a newer package version. - **Impact:** The child process may perform an update action; its exact behavior is unresolved. - **Evidence paths:** dist/launcher.js - **Review source:** ai\_review - **Reviewed:** 2026-10-21T15:25:18.747Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The update path passes an obfuscated string to a detached Node process using the -e option. - **Rationale:** Static inspection found an opaque detached child-process command in the launcher’s update path, alongside deliberate obfuscation in the published build. The inspected source does not establish a concrete attack, so this warrants a warning rather than a block. - **Files touched:** dist/launcher.js - **Network endpoints:** registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 76.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The launcher checks npm for a newer release and starts a detached Node process with an obfuscated inline command when one is found; the command’s behavior is unresolved., The published build runs an obfuscation script, and the shipped CLI and launcher use encoded string tables that make runtime behavior harder to audit. - **Evidence against:** The only declared lifecycle hook is prepublishOnly, which invokes the publishing build; no install-time hook is declared., The inspected launcher excerpts do not establish credential theft, command-output exfiltration, or another concrete attack. ## Affected versions and remediation This report applies to @funny-booth/agent-core@0.1.38. - Review the evidence and your use of @funny-booth/agent-core@0.1.38 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
