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 is not proven malware because there is no lifecycle execution or observed exfiltration. Its broad wallet-key discovery and payment capabilities are nevertheless a real dangerous runtime surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-09-11T18:06:22.742Z - **Finished:** 2026-09-11T18:07:30.024Z - **Download time:** 503 ms - **Static scan time:** 2082 ms - **AI review time:** 64693 ms - **Total time:** 67282 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:** At runtime, exported wallet helpers can inspect private keys in wallet.json files under arbitrary hidden home-directory folders. Explicit import can copy a selected discovered key into the package session, and API calls can sign x402 payments. - **Trigger:** Calling wallet discovery or import helpers, constructing the Anthropic-compatible client without credentials, or making a wallet-billed API request. - **Impact:** A consumer or agent that invokes these APIs can expose or reuse local wallet credentials and authorize USDC payments. - **Evidence paths:** dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T18:07:30.024Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Cross-application wallet-key discovery, local key copying, and payment signing. - **Rationale:** The package is not proven malware because there is no lifecycle execution or observed exfiltration. Its broad wallet-key discovery and payment capabilities are nevertheless a real dangerous runtime surface. - **Files touched:** \/.\*/wallet.json, \/.blockrun/.session, \/.blockrun/.session.backup-\ - **Network endpoints:** https://blockrun.ai/api ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The exported wallet scanner enumerates hidden home-directory folders and reads wallet.json private keys., An exported import function copies a discovered private key into the package wallet session file., Constructing the Anthropic-compatible client without credentials automatically creates or loads a wallet., Wallet payment signing is reachable through user-invoked API requests. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The inspected entrypoints do not execute scanning, network requests, or shell commands merely on import., The code does not send discovered private keys over the network; importing a discovered wallet requires an explicit function call. ## Affected versions and remediation This report applies to @blockrun/llm@3.14.2. - Review the evidence and your use of @blockrun/llm@3.14.2 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.
