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 package has risky install-time binary delivery and powerful runtime agent integration, including a Codex hook-trust bypass. Its visible safeguards and absence of confirmed exfiltration or broad foreign control-surface mutation make malicious intent unproven, but the residual risk warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-08-31T10:18:12.685Z - **Finished:** 2026-08-31T10:21:24.228Z - **Download time:** 1005 ms - **Static scan time:** 20779 ms - **AI review time:** 169758 ms - **Total time:** 191543 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 downloads checksum-pinned native helpers to the package-owned Negotium state directory. At runtime, its agent integration can copy Codex authentication data temporarily and launch Codex through a hook-trust-bypassing wrapper. - **Trigger:** npm postinstall, then use of the Negotium hosted-agent or Codex integration. - **Impact:** A compromised release host or a flaw in the local agent integration could affect the user's local agent environment; static inspection did not establish credential exfiltration or a foreign configuration mutation. - **Evidence paths:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, dist/hosted-agent.js, dist/mcp-factories.js, dist/agent-helpers.js, dist/runtime-helpers.js - **Review source:** ai\_review - **Reviewed:** 2026-08-31T10:21:24.228Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Native binary installation and privileged local agent-wrapper execution. - **Rationale:** The package has risky install-time binary delivery and powerful runtime agent integration, including a Codex hook-trust bypass. Its visible safeguards and absence of confirmed exfiltration or broad foreign control-surface mutation make malicious intent unproven, but the residual risk warrants a warning. - **Files touched:** ~/.negotium/binaries/browser-rs/v0.1.23/browser-rs, ~/.negotium/binaries/bash-rs/v0.1.7/bash-rs, ~/.codex/auth.json, ~/.claude/.credentials.json - **Network endpoints:** https://github.com/maestrojeong/browser-rs-mcp/releases/download/v0.1.23, https://github.com/maestrojeong/bash-rs-mcp/releases/download/v0.1.7 ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The install hook automatically downloads and installs native executables into the user's Negotium state directory., Runtime code creates a private Codex wrapper that invokes Codex with hook-trust bypass enabled., The package reads Codex authentication data into a temporary isolated directory during runtime setup., Agent helper code checks local Codex and Claude credential locations., Runtime helpers expose dynamic module loading through import.meta.require. - **Evidence against:** The installers pin release URLs and verify SHA-256 before installing a binary., The install hook only writes under the package's own .negotium state directory., The inspected DeepSeek request is a configured cron-summary feature using its official API host; no fixed unofficial credential gateway was found., The temporary Codex authentication copy is removed in a finally block., No self-dependency, foreign agent configuration write, or confirmed secret exfiltration was found. ## Affected versions and remediation This report applies to negotium@0.10.0. - Review the evidence and your use of negotium@0.10.0 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.
