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. The package deliberately obfuscates its published runtime, and the entrypoint imports an automatic feedback reporter whose endpoint and caller path remain unresolved. The inspected excerpts do not prove malicious behavior, 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:** 78.0% - **Started:** 2026-10-17T10:25:33.773Z - **Finished:** 2026-10-17T10:26:05.306Z - **Download time:** 255 ms - **Static scan time:** 252 ms - **AI review time:** 31025 ms - **Total time:** 31533 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 obfuscated runtime includes an automatically triggered feedback reporter, but inspection did not resolve its destination or full activation path. The available source does not establish a concrete attack. - **Trigger:** A selected failure may activate automatic feedback reporting; the exact caller path could not be resolved from the obfuscated entrypoint. - **Impact:** Possible failure-report disclosure remains unresolved; no confirmed credential theft or other attack behavior was identified. - **Evidence paths:** package.json, dist/index.js, dist/feedback.js - **Review source:** ai\_review - **Reviewed:** 2026-10-17T10:26:05.306Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The feedback helper sends a JSON body through a supplied request function, while encoded strings obscure the destination and report details. - **Rationale:** The package deliberately obfuscates its published runtime, and the entrypoint imports an automatic feedback reporter whose endpoint and caller path remain unresolved. The inspected excerpts do not prove malicious behavior, so this warrants a warning rather than a block. - **Files touched:** package.json, dist/index.js, dist/feedback.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The publish script explicitly obfuscates the distributed JavaScript, and the prepublishOnly hook runs that script., The main entrypoint imports the obfuscated feedback module, which posts a JSON body and automatically reports selected failures., The obfuscated strings prevent confirming the report destination, payload contents, and whether every reporting path is user-consented. - **Evidence against:** The inspected feedback helper submits a supplied JSON body; the excerpts do not establish credential collection, a malicious payload loader, or an unrelated recipient. ## Affected versions and remediation This report applies to @funny-booth/agent-core@0.1.34. - Review the evidence and your use of @funny-booth/agent-core@0.1.34 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.
