Cotal connector for Jcode: a host-mode mesh peer driven through Jcode's Harness API bridge.
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe connector's startup path mirrors credentials from several unrelated AI clients into its private Jcode home, expanding the agent's access without a visible consent check. I found no package-source evidence that those credentials are transmitted to an unrelated host, so this warrants a warning rather than a block.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
When the Cotal core launches a Jcode connector host seat.
Impact
The Jcode runtime can access credentials for other AI services and may use them to act through those services. The package source does not establish an unrelated-host transmission.
Mechanism
The host inventories credential files under the user's home directory and copies them into the seat's private Jcode home before starting Jcode; no opt-in guard is visible on this path.

The connector's startup path mirrors credentials from several unrelated AI clients into its private Jcode home, expanding the agent's access without a visible consent check.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- Starting a Jcode host seat calls mirrorJcodeCredentials before launching the private Jcode instance.
- The mirrored credential inventory includes files for Claude, Codex, Gemini, Cursor and GitHub Copilot.
- The mirror copies inventoried credentials into the private Jcode home; the source does not show this package transmitting them to a foreign host.
- The manifest exports a connector module and has no install lifecycle script.
Evidence against
- The package is a Jcode connector, and the credential mirroring occurs as part of its host startup flow.
- The reviewed package source does not establish that the mirrored credentials are sent to an unrelated host.
