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 an install-time malware chain, but its automatic signing of server-controlled payment terms and cross-application wallet-key discovery create a concrete high-impact wallet-drain capability. The absence of lifecycle hooks and evidence of covert exfiltration supports a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-11T18:06:22.472Z - **Finished:** 2026-09-11T18:07:29.208Z - **Download time:** 759 ms - **Static scan time:** 2096 ms - **AI review time:** 63878 ms - **Total time:** 66736 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:** A wallet-configured client automatically signs server-specified USDC payment authorizations after a 402 response. Separately, explicit wallet-discovery APIs read private keys from other hidden application directories. - **Trigger:** A caller invokes a paid client method with a wallet, or explicitly calls wallet discovery or import APIs. - **Impact:** A compromised or malicious configured API server could obtain a signed transfer authorization for an excessive amount; explicit import can copy another application's discovered wallet key into BlockRun storage. - **Evidence paths:** dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T18:07:29.208Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic signing of unbounded server-supplied payment details and explicit cross-application wallet discovery. - **Rationale:** The package is not an install-time malware chain, but its automatic signing of server-controlled payment terms and cross-application wallet-key discovery create a concrete high-impact wallet-drain capability. The absence of lifecycle hooks and evidence of covert exfiltration supports a warning rather than a block. - **Files touched:** dist/index.js, .blockrun/.session, \/.\*/wallet.json - **Network endpoints:** blockrun.ai, api.blockrun.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for warning:** Runtime payment handling signs a USDC transfer authorization using the recipient and amount supplied in a 402 response, without a local spending limit., Exported wallet-discovery functions enumerate hidden home-directory application folders and read wallet.json private keys., The package can write a selected discovered private key into its own session file when the caller invokes wallet import. - **Evidence against:** package.json has no preinstall, install, postinstall, or other lifecycle hook., The wallet scanning and import routines are exported functions, not import-time behavior., Network requests and payment signing are part of the package's stated API-client and payment functionality; no secret exfiltration endpoint was found. ## Affected versions and remediation This report applies to @blockrun/llm@3.15.0. - Review the evidence and your use of @blockrun/llm@3.15.0 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.
