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. No concrete malicious behavior was established, but automatic native-binary installation and permission-bypassing agent orchestration create a real elevated-capability risk. This warrants a warning rather than a publication block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-08T12:04:48.811Z - **Finished:** 2026-09-08T12:06:47.353Z - **Download time:** 512 ms - **Static scan time:** 23849 ms - **AI review time:** 94180 ms - **Total time:** 118542 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:** Installation downloads verified native tools into the package-owned Negotium state directory. When its runtime is used, it can run a permission-bypassing Claude agent, write Claude session data, and submit cron prompts to a configured LLM endpoint. - **Trigger:** Installing the package runs postinstall; invoking its runtime activates the agent and cron features. - **Impact:** A user who runs the runtime grants it substantial local agent capability; configured cron prompts may leave the machine for LLM summarization. - **Evidence paths:** package.json, install-browser-rs.mjs, dist/hosted-agent.js, dist/agent-helpers.js, dist/runtime/cron/summarize.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-08T12:06:47.353Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Native-tool bootstrap and user-invoked privileged agent orchestration. - **Rationale:** No concrete malicious behavior was established, but automatic native-binary installation and permission-bypassing agent orchestration create a real elevated-capability risk. This warrants a warning rather than a publication block. - **Files touched:** ~/.negotium/binaries/browser-rs/v0.3.2/browser-rs, ~/.claude/projects/\/\.jsonl - **Network endpoints:** https://github.com/maestrojeong/browser-rs-mcp/releases/download/${VERSION}, https://api.deepseek.com/v1/chat/completions ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Its postinstall hook automatically runs two installers., The browser installer downloads, verifies, and installs an executable under the user's Negotium state directory., Runtime launches Claude with permission bypass enabled., Runtime writes synthetic session records into Claude's user directory., Cron prompt summaries can send a configured API-key request to DeepSeek or an environment-selected URL. - **Evidence against:** Downloaded installer payloads are checked against hard-coded SHA-256 values before installation., The installer writes only to the package-owned .negotium state area., The DeepSeek call requires a supplied API key and uses the official endpoint by default., No source evidence shows secret harvesting, unsolicited external exfiltration, or install-time mutation of Codex or Claude configuration. ## Affected versions and remediation This report applies to negotium@0.14.2. - Review the evidence and your use of negotium@0.14.2 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.
