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. Pattern generation activates opaque code that is decrypted using a remotely fetched key and evaluated at runtime. No confirmed malicious payload behavior is statically visible. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-28T06:06:14.280Z - **Finished:** 2026-09-28T06:07:22.901Z - **Download time:** 780 ms - **Static scan time:** 391 ms - **AI review time:** 67449 ms - **Total time:** 68621 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:** Pattern generation activates opaque code that is decrypted using a remotely fetched key and evaluated at runtime. No confirmed malicious payload behavior is statically visible. - **Trigger:** A user invokes the MCP pattern-generation tool. - **Impact:** The opaque plaintext runs with the privileges of the user running the MCP server, so its behavior cannot be verified from this package snapshot. - **Evidence paths:** dist/mcp.js, dist/core.enc.json - **Review source:** ai\_review - **Reviewed:** 2026-09-28T06:07:22.901Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The MCP entry point reads the encrypted algorithm, fetches a key from the configured service, decrypts it, and executes the plaintext with the Function constructor. - **Rationale:** The package uses remote-keyed encrypted code and dynamic evaluation for its core function, preventing meaningful static verification. There is no install-time execution or confirmed malicious action, so a warning is warranted rather than a block. - **Files touched:** dist/core.enc.json - **Network endpoints:** https://pindoupic.com/api/v1/crypto/algo-key ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package exposes CLI and MCP entry points and has no install lifecycle hook., The MCP code retrieves a key from the package service for an encrypted local code blob., The decrypted blob is executed with the Function constructor when pattern generation is requested., The bundled algorithm file is opaque encrypted data, preventing static verification of the executed code. ## Affected versions and remediation This report applies to @javascribe/pindoupic@0.4.0. - Review the evidence and your use of @javascribe/pindoupic@0.4.0 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.
