Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 3.22.1 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The scanner's wallet-transfer matches resolve to payment signing that uses the recipient and amount from a service payment challenge. The manifest has no install hook, and the inspected wallet-discovery code warns that other wallets are not adopted automatically. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-18T12:03:03.283Z - **Finished:** 2026-10-18T12:03:57.634Z - **Download time:** 1291 ms - **Static scan time:** 2130 ms - **AI review time:** 50926 ms - **Total time:** 54351 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 attack was identified. The wallet transfer behavior inspected is part of caller-triggered, challenge-based payment handling. - **Trigger:** A caller uses a payment-enabled API operation and the service returns a payment challenge. - **Impact:** No unauthorized transfer or credential disclosure was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-18T12:03:57.634Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client signs the challenge's stated recipient and amount; wallet discovery is used for a migration notice, with adoption requiring an explicit address. - **Rationale:** The scanner's wallet-transfer matches resolve to payment signing that uses the recipient and amount from a service payment challenge. The manifest has no install hook, and the inspected wallet-discovery code warns that other wallets are not adopted automatically. ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json routes imports and requires to the inspected runtime bundles and defines no install lifecycle hook., The CommonJS bundle signs USDC payment authorizations for the supplied recipient and amount, with an asset check against the selected network., The JavaScript bundle passes the parsed payment challenge's recipient and amount into the payment signer and validates the resource URL against the configured API base., Wallet adoption is exposed through an explicit address argument; setup reports discovered wallets and says they are not adopted automatically. ## Affected versions and remediation This report applies to @blockrun/llm@3.22.1. - Review the evidence and your use of @blockrun/llm@3.22.1 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.
