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 install-time remote native payload is a real supply-chain attack surface and warrants a warning. Pinned integrity checks and the absence of a concrete malicious behavior rule out a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-08-09T21:56:48.451Z - **Finished:** 2026-08-09T21:57:43.620Z - **Download time:** 503 ms - **Static scan time:** 12556 ms - **AI review time:** 42108 ms - **Total time:** 55169 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 scripts download verified native browser and shell helper binaries, then make them executable in Negotium state storage. This is a meaningful remote-native-payload risk but no concrete malicious chain was found. - **Trigger:** npm postinstall; later Negotium browser/background-shell use - **Impact:** A compromised or incorrectly trusted pinned release binary would run with the installing user's privileges. - **Evidence paths:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, dist/main.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T21:57:43.620Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** verified remote binary download and execution - **Rationale:** The install-time remote native payload is a real supply-chain attack surface and warrants a warning. Pinned integrity checks and the absence of a concrete malicious behavior rule out a block. - **Files touched:** 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:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs postinstall downloaders., Both install scripts fetch and chmod native executables., Downloaded binaries execute later as browser/bash runtime helpers. - **Evidence against:** Downloads use fixed GitHub URLs and pinned SHA-256 checks., Installers only write under configured ~/.negotium state., No source evidence of credential exfiltration or foreign agent-config mutation., README describes this as a multi-agent CLI with browser/terminal adapters. ## Affected versions and remediation This report applies to negotium@0.2.20. - Review the evidence and your use of negotium@0.2.20 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.
