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 MCP executable contains an opaque encrypted algorithm that is unlocked by a remote key and dynamically executed. No confirmed data theft or install-time attack was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-28T08:08:48.527Z - **Finished:** 2026-09-28T08:09:50.259Z - **Download time:** 1009 ms - **Static scan time:** 458 ms - **AI review time:** 60264 ms - **Total time:** 61732 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:** The MCP executable contains an opaque encrypted algorithm that is unlocked by a remote key and dynamically executed. No confirmed data theft or install-time attack was identified. - **Trigger:** A user invokes bead-pattern generation through the MCP server. - **Impact:** The executable behavior cannot be statically audited while the remote key enables its opaque payload. - **Evidence paths:** dist/mcp.js, dist/core.enc.json - **Review source:** ai\_review - **Reviewed:** 2026-09-28T08:09:50.259Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime fetches a key, decrypts dist/core.enc.json, and evaluates the decrypted source. - **Rationale:** This is an active remote-key-gated opaque code path executed during normal use, so its behavior cannot be verified by static review. The absence of an install lifecycle hook and confirmed exfiltration makes a warning more proportionate than a block. - **Files touched:** dist/mcp.js, dist/core.enc.json - **Network endpoints:** https://www.pindoupic.com/api/v1/crypto/algo-key ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The manifest declares encrypted algorithm distribution with a remotely supplied key and exposes MCP and CLI executables., The MCP runtime requests an algorithm key from the configured service., It decrypts bundled content and executes the resulting text with the Function constructor., Pattern generation awaits that decrypted module before processing input. - **Evidence against:** The manifest has no preinstall, install, or postinstall lifecycle hook., The inspected MCP path contains no credential collection or transmission. ## Affected versions and remediation This report applies to @javascribe/pindoupic@0.5.1. - Review the evidence and your use of @javascribe/pindoupic@0.5.1 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.
