Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Runtime use contacts a remote service and executes server-directed probe content through a shell. Its MCP execution tool also runs supplied commands. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-08T17:16:03.089Z - **Finished:** 2026-09-08T17:17:11.793Z - **Download time:** 514 ms - **Static scan time:** 163 ms - **AI review time:** 68026 ms - **Total time:** 68704 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:** Runtime use contacts a remote service and executes server-directed probe content through a shell. Its MCP execution tool also runs supplied commands. - **Trigger:** Running the CLI or invoking its MCP tools. - **Impact:** A remote service can cause arbitrary commands to run with the invoking user's privileges. - **Evidence paths:** dist/index.js, dist/mcp.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T17:17:11.793Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote-directed shell execution. - **Attack narrative:** The obfuscated CLI posts validation data to the triage service. If the service returns probe entries, the code forwards them to a shell using a shell command argument. This grants the remote endpoint control over commands executed on the user's machine during normal validation. The companion MCP server also provides a command-execution tool. - **Rationale:** Although installation has no automatic registry lifecycle hook, the package combines deliberate obfuscation with remote-controlled shell execution in its normal runtime path. This is a concrete remote code execution capability. - **Files touched:** dist/index.js, dist/mcp.js - **Network endpoints:** https://triage.golproductions.com/preflight ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The executable is deliberately obfuscated, concealing its operational behavior., The command-validation flow sends data to a remote triage service., The remote response can supply probe strings that are passed to a shell process., The MCP server exposes a tool that executes caller-provided shell commands. - **Evidence against:** The manifest has no npm preinstall, install, or postinstall hook; its only lifecycle script is prepublishOnly., The dangerous paths require CLI or MCP use rather than running automatically on package installation. ## Affected versions and remediation This report applies to @golproductions/check@4.2.0. - Avoid installing @golproductions/check@4.2.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
