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 checksum-verified install of documented, package-owned binaries, not a foreign AI-agent control-surface mutation. Runtime shell and HTTPS capabilities are explicit MCP features with credential-bound/redacted handling; no concrete malicious chain was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-08-09T21:56:51.310Z - **Finished:** 2026-08-09T21:57:53.679Z - **Download time:** 508 ms - **Static scan time:** 9686 ms - **AI review time:** 52174 ms - **Total time:** 62369 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 confirmed malicious attack surface. Postinstall fetches two checksum-pinned, package-owned helper binaries; runtime command/network capabilities are exposed as documented MCP features. - **Trigger:** npm postinstall; later explicit Negotium CLI/MCP use - **Impact:** Installs browser/bash helper binaries under Negotium state; runtime can execute requested commands or HTTPS credential operations. - **Evidence paths:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, dist/runtime/src/mcp/vault-run.ts, dist/runtime/src/mcp/vault-http.ts, dist/runtime/src/agents/codex-native-multi-agent.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-09T21:57:53.679Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** verified helper-binary installation and user-invoked agent runtime tools - **Rationale:** The lifecycle behavior is a checksum-verified install of documented, package-owned binaries, not a foreign AI-agent control-surface mutation. Runtime shell and HTTPS capabilities are explicit MCP features with credential-bound/redacted handling; no concrete malicious chain was found. - **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 ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json defines postinstall., install-browser-rs.mjs downloads and installs a native executable., install-bash-rs.mjs downloads and installs a native executable., dist/runtime/src/mcp/vault-run.ts can run user-requested credential-bearing shell commands. - **Evidence against:** Install downloads are pinned to GitHub release URLs and SHA-256 verified., Installers only write Negotium-owned ~/.negotium binaries and can be skipped by env flags., No source evidence of credential harvesting or hard-coded exfiltration endpoint., Vault HTTP/shell functions require explicit MCP inputs and redact returned secret material., Agent-session writes are runtime features, not lifecycle execution. ## Affected versions and remediation This report applies to negotium@0.2.17. - Review the evidence and your use of negotium@0.2.17 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.
