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. The package can execute opaque code controlled by a remotely supplied decryption key. This affects both its CLI and MCP execution paths. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-28T06:06:23.123Z - **Finished:** 2026-09-28T06:07:21.170Z - **Download time:** 765 ms - **Static scan time:** 355 ms - **AI review time:** 56927 ms - **Total time:** 58047 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 package can execute opaque code controlled by a remotely supplied decryption key. This affects both its CLI and MCP execution paths. - **Trigger:** A user runs pattern generation through the CLI or MCP tool. - **Impact:** The service controlling the key can cause arbitrary JavaScript to run in the invoking user's process. - **Evidence paths:** dist/cli.js, dist/mcp.js, dist/core.enc.json - **Review source:** ai\_review - **Reviewed:** 2026-09-28T06:07:21.170Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoints fetch a key, decrypt bundled ciphertext, and pass the plaintext to the Function constructor. - **Attack narrative:** When pattern generation is requested, either entrypoint retrieves a remote key, decrypts an opaque bundled payload, and executes it dynamically. Because the executable code is not available for package review and the key provider can change what decrypts, the remote service controls code that runs in the user's local process. - **Rationale:** Opaque bundled code is decrypted using remotely supplied material and actively executed through the Function constructor. This is a concrete remote code execution path, not an inert encrypted asset. - **Files touched:** dist/cli.js, dist/mcp.js, dist/core.enc.json - **Network endpoints:** https://pindoupic.com/api/v1/crypto/algo-key ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Both executable entrypoints fetch a decryption key from the package service., The MCP entrypoint decrypts bundled opaque data and executes the resulting text with the Function constructor., Pattern generation activates the MCP decryption-and-execution routine., The encrypted payload is included as a large opaque data file. - **Evidence against:** No install lifecycle hook is declared in package metadata., No credential collection or outbound secret transmission was identified in the inspected behavior. ## Affected versions and remediation This report applies to @javascribe/pindoupic@0.3.0. - Avoid installing @javascribe/pindoupic@0.3.0. 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.
