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. No source evidence establishes credential theft, agent-control hijacking, destructive behavior, or a self-dependency chain. Automatic download of opaque executables during postinstall remains a real supply-chain risk that warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-14T12:45:28.839Z - **Finished:** 2026-09-14T12:47:03.526Z - **Download time:** 260 ms - **Static scan time:** 15267 ms - **AI review time:** 79159 ms - **Total time:** 94687 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:** Installing the package automatically retrieves two opaque native executables. One is later started by the background-shell feature. - **Trigger:** npm installation runs postinstall; using the background-shell feature starts the bash binary. - **Impact:** A pinned but uninspectable executable is written to the user's package-specific state directory and can run with that user's permissions. - **Evidence paths:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, dist/background-bash.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T12:47:03.526Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall native-binary download and later child-process launch. - **Rationale:** No source evidence establishes credential theft, agent-control hijacking, destructive behavior, or a self-dependency chain. Automatic download of opaque executables during postinstall remains a real supply-chain risk that warrants a warning. - **Files touched:** install-browser-rs.mjs, install-bash-rs.mjs, dist/background-bash.js, .negotium/binaries/browser-rs/v0.4.5/browser-rs, .negotium/binaries/bash-rs/v0.1.10/bash-rs - **Network endpoints:** github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The npm postinstall hook automatically runs two native-binary installers., Both installers download opaque platform executables, make them executable, and place them in the user's Negotium state directory., The runtime later starts the downloaded bash executable as a child process. - **Evidence against:** The installers pin SHA-256 hashes and reject a downloaded file whose hash differs., The install hook writes only under the package-specific Negotium state directory; no foreign agent configuration write was found., The DeepSeek request uses an explicit configured key and its documented default endpoint; no fixed unofficial credential gateway was found. ## Affected versions and remediation This report applies to negotium@0.16.0. - Review the evidence and your use of negotium@0.16.0 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.
