@linzumi/cli@1.0.260
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-aiThis is a high-risk agent-management and remote-execution tool, but source inspection found no install hook, stealth trigger, or confirmed credential theft. Its capabilities warrant a warning rather than a malware block.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Running linzumi commands, including VM and runner workflows.
Impact
A compromised service or authorized remote workflow could cause code execution in the downloaded runtime or VM context.
Mechanism
Remote runtime download and cloud VM shell execution.
AI rationale
This is a high-risk agent-management and remote-execution tool, but source inspection found no install hook, stealth trigger, or confirmed credential theft. Its capabilities warrant a warning rather than a malware block.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The installed CLI imports and runs its bundled implementation when the user invokes the linzumi command.
- The implementation fetches a server-selected editor runtime archive, extracts it into the user cache, and later uses its executable.
- The vm agent-exec command passes user-supplied arguments to sh -c in a persistent cloud VM.
- The launcher sends startup telemetry to the Linzumi service by default.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- The risky capabilities are reached through explicit CLI commands, not package installation or import alone.
- No source-confirmed credential harvesting or unrelated secret exfiltration was found.
