@linzumi/cli@1.0.256
Linzumi CLI — point a Codex agent at the real code on your laptop, with your team watching and steering from shared threads.
AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo automatic installation behavior or concrete malware action was found. The remote agent and credential-persistence capability remains a real, incompletely auditable risk.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user invokes the linzumi CLI connection, login, or cloud-agent features.
Impact
A user-authorized agent may access the selected workspace and transmit data to Linzumi services; the complete cloud runtime flow remains difficult to verify statically.
Mechanism
A remote-connected coding-agent runner and TCP tunnel use supplied credentials.
AI rationale
No automatic installation behavior or concrete malware action was found. The remote agent and credential-persistence capability remains a real, incompletely auditable risk.

Decision evidence
public snapshotAI called this Suspicious at 72.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The CLI dynamically loads a TCP tunnel module for user-invoked login and connection commands.
- The bundled tunnel module defines Linzumi WebSocket and service endpoints.
- The cloud supervisor accepts an MCP authentication value and writes it to a cloud guest filesystem.
- The published package contains large bundled runtime artifacts whose full cloud-agent data flow is not readily auditable statically.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- The executable is activated through the linzumi command, not on package installation.
- No source fact established covert credential exfiltration, remote payload evaluation, or destructive action.
