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 source is heavily obfuscated and performs portal authentication and bearer-token requests, but inspected evidence does not establish credential theft, an unrestricted credential destination, or another concrete attack. Classify as suspicious because behavior and reporting activation remain unresolved. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 75.0% - **Started:** 2026-10-12T02:55:27.208Z - **Finished:** 2026-10-12T02:56:01.146Z - **Download time:** 1278 ms - **Static scan time:** 331 ms - **AI review time:** 32329 ms - **Total time:** 33938 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:** No concrete attack was confirmed. Obfuscated launcher and portal request code leave unresolved uncertainty about credential and token handling. - **Trigger:** Running the published CLI or invoking a knowledge or feedback operation. - **Impact:** The inspected code is consistent with portal authentication and API use, but obfuscation and incomplete destination or activation evidence prevent confirming the handling scope. - **Evidence paths:** package.json, dist/launcher.js, dist/index.js, dist/feedback.js, launcher.config.json - **Review source:** ai\_review - **Reviewed:** 2026-10-12T02:56:01.146Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher posts entered login credentials to its configured portal; the main module sends a bearer token to that portal, and feedback code posts a token and JSON body to a supplied base URL. - **Rationale:** The source is heavily obfuscated and performs portal authentication and bearer-token requests, but inspected evidence does not establish credential theft, an unrestricted credential destination, or another concrete attack. Classify as suspicious because behavior and reporting activation remain unresolved. - **Files touched:** package.json, dist/launcher.js, dist/index.js, dist/feedback.js, launcher.config.json - **Network endpoints:** https://app.ai-agentos.jp ### Review decision - **Verdict:** Suspicious - **Confidence:** 75.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes dist/index.js as its main module and agent-core and salesbot command entrypoints., The obfuscated launcher sends an email and password in a POST request, but the destination is resolved through launcher configuration and is not fully inspectable from the excerpt., The main module sends a bearer token to its configured portal for a knowledge request., The feedback module sends a bearer token and JSON body to a caller-provided base URL; the inspected excerpt does not establish how that URL is restricted or how reporting is activated. - **Evidence against:** The inspected package manifest has no preinstall, install, or postinstall hook., The included launcher configuration points to the product portal app.ai-agentos.jp., The inspected login flow sends credentials entered into the launcher, consistent with portal authentication. ## Affected versions and remediation This report applies to @funny-booth/agent-core@0.1.21. - Review the evidence and your use of @funny-booth/agent-core@0.1.21 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.
