Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected JavaScript indicates the prebuilt executables can be activated for proof hashing, but host analysis could not resolve either executable's behavior. No independent attack evidence was established, so the unresolved native behavior requires manual review. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-28T22:16:19.388Z - **Finished:** 2026-10-28T22:16:41.947Z - **Download time:** 510 ms - **Static scan time:** 156 ms - **AI review time:** 21892 ms - **Total time:** 22559 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 in the inspected JavaScript. The behavior of two shipped native executables remains unresolved. - **Trigger:** The CLI may invoke the platform-matching native executable when resolving its hasher. - **Impact:** The unresolved executable behavior prevents a clean verdict; no concrete attack impact is established. - **Evidence paths:** native/prebuilt/darwin-x64/b20miner-hasher, native/prebuilt/darwin-arm64/b20miner-hasher, .lpm-inspection-XTrFBz/0-0f579ee8f374.txt, .lpm-inspection-XTrFBz/1-8cbb241f6962.txt, dist/hasher.js - **Review source:** ai\_review - **Reviewed:** 2026-10-28T22:16:41.947Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The executables are shipped in the package and selected by the hasher, but available offline analysis could not determine their behavior. - **Rationale:** The inspected JavaScript indicates the prebuilt executables can be activated for proof hashing, but host analysis could not resolve either executable's behavior. No independent attack evidence was established, so the unresolved native behavior requires manual review. - **Files touched:** native/prebuilt/darwin-x64/b20miner-hasher, native/prebuilt/darwin-arm64/b20miner-hasher ### Review decision - **Verdict:** Manual Review - **Confidence:** 99.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest exposes a CLI and includes the native prebuilt directory in the package., The hasher selects a platform-specific prebuilt executable unless the JavaScript fallback is explicitly selected., The offline analysis could not determine the behavior of the Darwin x64 executable., The offline analysis could not determine the behavior of the Darwin arm64 executable. - **Evidence against:** The manifest lists no install lifecycle scripts., The inspected JavaScript shows the native executable is used for proof hashing; no separate attack behavior was established. ## Affected versions and remediation This report applies to b20miner@0.3.2. - Review the evidence and your use of b20miner@0.3.2 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.
