Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The lifecycle behavior is a transparent, pinned-checksum bootstrap for this package's advertised helpers, not a concrete malicious chain. Agent and shell capabilities are activated by explicit runtime use, with no confirmed exfiltration or broad control-surface write. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-08-09T22:04:54.902Z - **Finished:** 2026-08-09T22:06:03.016Z - **Download time:** 518 ms - **Static scan time:** 11052 ms - **AI review time:** 56543 ms - **Total time:** 68114 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:** Install-time download installs two checksum-verified, package-aligned helper binaries. No credential exfiltration, remote payload execution beyond those pinned binaries, or foreign AI-agent configuration mutation was confirmed. - **Trigger:** npm postinstall; runtime actions require explicit negotium CLI or hosted-agent use. - **Impact:** Installs browser and background-shell helpers under the package state directory. - **Evidence paths:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, dist/main.js, dist/runtime/src/agents/codex-native-multi-agent.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-09T22:06:03.016Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** verified helper-binary bootstrap and user-invoked multi-agent runtime - **Rationale:** The lifecycle behavior is a transparent, pinned-checksum bootstrap for this package's advertised helpers, not a concrete malicious chain. Agent and shell capabilities are activated by explicit runtime use, with no confirmed exfiltration or broad control-surface write. - **Files touched:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, ~/.negotium/binaries/browser-rs/v0.1.19/browser-rs, ~/.negotium/binaries/bash-rs/v0.1.5/bash-rs - **Network endpoints:** https://github.com/maestrojeong/browser-rs-mcp/releases/download/v0.1.19, https://github.com/maestrojeong/bash-rs-mcp/releases/download/v0.1.5, http://127.0.0.1 ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json postinstall runs two installers., Installers download native binaries to ~/.negotium., dist/runtime/src/agents/fixtures/claude-attachments.jsonl contains instruction-like captured transcript text. - **Evidence against:** Both installers use fixed GitHub release URLs and pinned SHA-256 checks., Installers only write versioned browser-rs/bash-rs files under ~/.negotium., dist/main.js dispatches behavior only after explicit CLI invocation., Runtime network traffic is localhost MCP/control traffic or configured AI-provider use. ## Affected versions and remediation This report applies to negotium@0.2.33. - Review the evidence and your use of negotium@0.2.33 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.
