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 CLI is user-invoked and has no install lifecycle, but the entire runtime is obfuscated while config code reads the API key and loads fs and os. That hides destinations and file writes enough to warn, without a proven theft or remote-execution chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 64.0% - **Started:** 2026-09-27T19:32:44.792Z - **Finished:** 2026-09-27T19:33:50.534Z - **Download time:** 520 ms - **Static scan time:** 3997 ms - **AI review time:** 61224 ms - **Total time:** 65742 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:** The published CLI entry loads heavily obfuscated modules, including a config loader that touches the filesystem and the API key environment variable. No install hook or confirmed exfiltration sink was identified, but the obfuscation hides the actual request destinations and file writes. - **Trigger:** User or agent invocation of the numbots bin, which requires dist/main.js. - **Impact:** A consumer cannot verify from source whether the key or local files stay bound to the intended accounting service. - **Evidence paths:** bin/cli.js, dist/main.js, dist/config.js, dist/mcp-tools.js, dist/commands/forecast.js - **Review source:** ai\_review - **Reviewed:** 2026-09-27T19:33:50.534Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated runtime code loads fs and os and reads NUMBORS\_API\_KEY and NUMBORS\_URL; further network and file operations stay encoded. - **Rationale:** The CLI is user-invoked and has no install lifecycle, but the entire runtime is obfuscated while config code reads the API key and loads fs and os. That hides destinations and file writes enough to warn, without a proven theft or remote-execution chain. ### Review decision - **Verdict:** Suspicious - **Confidence:** 64.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** High - **Evidence for warning:** package.json has no preinstall, install, or postinstall script; scripts are build, test, and prepublishOnly only., bin/cli.js loads dist/main.js when the numbots command runs, with a fallback require of src/main., dist/main.js, dist/mcp-tools.js, and dist/commands/forecast.js are single-line string-array obfuscation, so their calls cannot be read statically., dist/config.js requires the fs and os modules through hex escapes and reads process.env.NUMBORS\_API\_KEY and process.env.NUMBORS\_URL. - **Evidence against:** No child\_process, eval, Function, or writeFile literals appear in the package., There is no runtime dependency on the package name and no install-time hook., README describes a user-run accounting CLI that stores a key the user supplies. ## Affected versions and remediation This report applies to numbors@1.5.0. - Review the evidence and your use of numbors@1.5.0 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.
