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 is not proven malicious, but its postinstall hook stages externally hosted native executables that are later launched. Hash pinning and inspected secret protections lower the risk, yet do not remove the install-time native payload boundary. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-07T13:28:33.309Z - **Finished:** 2026-09-07T13:30:20.651Z - **Download time:** 1033 ms - **Static scan time:** 22012 ms - **AI review time:** 84295 ms - **Total time:** 107342 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:** On npm installation, the package downloads two pinned native binaries into its own Negotium state directory and makes them executable. One is later launched by the package's runtime. - **Trigger:** npm installation runs postinstall; a later Negotium runtime action starts the background command service. - **Impact:** A release-hosted native artifact becomes executable on the host outside the normal npm tarball review boundary. - **Evidence paths:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, dist/hosted-agent.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T13:30:20.651Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall native binary download followed by runtime process launch. - **Rationale:** The package is not proven malicious, but its postinstall hook stages externally hosted native executables that are later launched. Hash pinning and inspected secret protections lower the risk, yet do not remove the install-time native payload boundary. - **Files touched:** .negotium/binaries/browser-rs/v0.3.2/browser-rs, .negotium/binaries/bash-rs/v0.1.7/bash-rs - **Network endpoints:** https://github.com/maestrojeong/browser-rs-mcp/releases/download/v0.3.2, https://github.com/maestrojeong/bash-rs-mcp/releases/download/v0.1.7 ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** Installation automatically runs two downloader scripts., The installer fetches a native executable, verifies a fixed hash, and saves it executable in the user's Negotium state directory., The runtime can launch the installed background command service., The package contains AI-agent and credential-handling runtime code. - **Evidence against:** The downloaded browser binary is checked against a hard-coded SHA-256 before installation., The inspected credential hook blocks access to runtime secret storage and redacts output., No self-dependency, foreign agent-configuration write, credential exfiltration endpoint, or hidden payload execution was found in the inspected sources. ## Affected versions and remediation This report applies to negotium@0.14.1. - Review the evidence and your use of negotium@0.14.1 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.
