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 CLI reaches bundled runtime code whose encoded strings and decoder logic prevent reliable assessment from the inspected excerpts. No concrete attack was established, but the opaque reachable behavior remains unresolved and warrants manual review. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-19T10:34:50.489Z - **Finished:** 2026-10-19T10:35:23.067Z - **Download time:** 3300 ms - **Static scan time:** 4412 ms - **AI review time:** 24865 ms - **Total time:** 32578 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 concrete attack was established from the inspected source. The CLI loads heavily obfuscated runtime files, leaving their behavior unresolved. - **Trigger:** Invoking the \`numbors\` CLI loads \`dist/main.js\`. - **Impact:** The opaque runtime behavior could not be assessed, so malicious impact is unconfirmed. - **Evidence paths:** dist/main.js, dist/mcp-tools.js, dist/commands/forecast.js - **Review source:** ai\_review - **Reviewed:** 2026-10-19T10:35:23.067Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Encoded string tables and decoder logic obscure the runtime behavior in the CLI bundle and flagged modules. - **Rationale:** The CLI reaches bundled runtime code whose encoded strings and decoder logic prevent reliable assessment from the inspected excerpts. No concrete attack was established, but the opaque reachable behavior remains unresolved and warrants manual review. - **Files touched:** package.json, bin/cli.js, dist/main.js, dist/mcp-tools.js, dist/commands/forecast.js ### Review decision - **Verdict:** Manual Review - **Confidence:** 78.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The CLI entrypoint loads \`dist/main.js\` when invoked., \`dist/main.js\`, \`dist/mcp-tools.js\`, and \`dist/commands/forecast.js\` begin with encoded string tables and decoder logic that obscure their runtime behavior., The manifest's \`prepublishOnly\` hook runs tests and a build; no install-time hook is declared. - **Evidence against:** The inspected source did not establish a concrete malicious action, credential transfer, or network recipient., The manifest's \`prepublishOnly\` command is limited to tests and building. ## Affected versions and remediation This report applies to numbors@1.6.0. - Review the evidence and your use of numbors@1.6.0 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.
