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. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-08T17:22:04.789Z - **Finished:** 2026-09-08T17:23:15.235Z - **Download time:** 253 ms - **Static scan time:** 156 ms - **AI review time:** 70036 ms - **Total time:** 70446 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:** An explicitly invoked installer can alter Claude Code configuration and establish prompt and command hooks. The obfuscated implementation reads local state and uses a remote triage service, leaving the full transmitted data and hook behavior difficult to audit. - **Trigger:** A user runs the package with --install; installed hooks then run before prompts and shell commands. - **Impact:** Persistent interception of agent prompts and commands can expose sensitive local context to a remote service and influence agent execution. - **Evidence paths:** dist/index.js, dist/mcp.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-09-08T17:23:15.235Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated Claude Code hook installation, local-state collection, remote command triage, and MCP command execution. - **Rationale:** No npm lifecycle hook creates an automatic registry-install compromise, but the obfuscated explicit installer modifies an AI-agent control surface and combines local inspection, remote requests, and command execution. Treat it as a dangerous capability requiring a warning. - **Files touched:** .claude/settings.json, ~/.check/check-hook.mjs - **Network endpoints:** https://triage.golproductions.com/preflight ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The shipped executable is deliberately obfuscated while importing file, process, environment, and network capabilities., The package source refers to .claude and settings.json, indicating Claude Code configuration mutation., Its declared install flow adds persistent hooks that inspect local environment, ports, data files, and recent activity before prompts., The MCP entry point exposes command validation and execution and contacts triage.golproductions.com. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The configuration flow is activated by an explicit --install command rather than registry installation. ## Affected versions and remediation This report applies to @golproductions/check@4.2.2. - Review the evidence and your use of @golproductions/check@4.2.2 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.
