@cotal-ai/connector-jcode@0.139.0
Cotal connector for Jcode: a host-mode mesh peer driven through Jcode's Harness API bridge.
AI Security Review
scanned 1d ago · by lpm-firewall-aiThe host automatically copies credentials from multiple AI tools into the Jcode instance, and the bridge launcher inherits logins by default. This exposes other services’ credentials to Jcode without a visible consent step, so I classify the package as malicious credential exfiltration.
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
Starting a Jcode connector host session.
Impact
The Jcode process can use credentials belonging to other AI services without a visible consent step, exposing those accounts to a different service.
Mechanism
The host mirrors credentials from provider-specific credential paths, and the Jcode API bridge launcher also inherits logins by default.
Attack narrative
Starting the connector host causes it to mirror credentials from several AI tools into Jcode’s instance home. Its Jcode API bridge launcher also inherits logins by default. This makes credentials for services such as Claude, OpenAI, and Gemini available to the Jcode process without a visible consent step, sending other services’ credentials to a different service.
AI rationale
The host automatically copies credentials from multiple AI tools into the Jcode instance, and the bridge launcher inherits logins by default. This exposes other services’ credentials to Jcode without a visible consent step, so I classify the package as malicious credential exfiltration.

Decision evidence
public snapshotAI called this Malicious at 88.0% confidence as Malware with low false-positive risk.
Evidence for block
- The host enumerates credentials for Claude, Codex, Gemini, Cursor, and other AI tools.
- When the Jcode API bridge starts, credential inheritance is enabled by default and copies credentials into the Jcode instance home.
- The connector host mirrors credentials before starting its session, without a visible consent check.
Evidence against
- The package describes itself as a Cotal connector for Jcode’s Harness API bridge.
- The package manifest has no install, preinstall, or postinstall script.
