Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 14 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Unknown - **Selected version:** 0.1.41 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 inspected source does not establish credential theft, destructive behavior, or an install-hook attack. The obfuscated runtime and automatic global update leave a concrete but unresolved execution risk, so this warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-22T17:50:19.726Z - **Finished:** 2026-10-22T17:51:12.762Z - **Download time:** 1028 ms - **Static scan time:** 293 ms - **AI review time:** 51715 ms - **Total time:** 53036 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 confirmed attack was identified. The obfuscated launcher automatically checks for a newer release and installs the latest package globally when it detects one, leaving update execution risk unresolved. - **Trigger:** A user runs the agent-core launcher and a newer package version is available. - **Impact:** The update path can replace the global installation without a separate confirmation in the inspected source; the obfuscated runtime limits behavior verification. - **Evidence paths:** dist/launcher.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T17:51:12.762Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher starts a detached process that runs npm to install the package’s latest release globally. - **Rationale:** The inspected source does not establish credential theft, destructive behavior, or an install-hook attack. The obfuscated runtime and automatic global update leave a concrete but unresolved execution risk, so this warrants a warning. - **Files touched:** dist/launcher.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes an obfuscated launcher as its executable and builds published output with an obfuscation step., When the launcher runs, it checks the latest package version and starts a detached process to install the latest release globally., The update installer invokes npm with the package name and @latest; this creates an automatic update path with unresolved execution risk., The feedback module sends automatic reports only for selected error codes, and the inspected dependencies show ordinary package identities and entrypoints. - **Evidence against:** The manifest has only a prepublishOnly build hook; no install-time hook was found., The launcher update check is part of the package’s launcher functionality, and the inspected update code checks for a newer version before installing. ## Affected versions and remediation This report applies to @funny-booth/agent-core@0.1.41. - Review the evidence and your use of @funny-booth/agent-core@0.1.41 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.
