OpenAI-compatible LLM proxy with automatic provider failover, streaming support, and a terminal UI to manage providers, models and priority order.

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

This is not proven malware, but automatic daemon startup and global login persistence are risky install-time behavior. The optional WARP routing is a dangerous dual-use capability explicitly intended to work around rate limits.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

npm install starts the daemon; a global install enables login startup; a user invokes the WARP feature to download tunnel tools.

Impact

The package can leave a background process and user-level startup entry after installation, and its optional network tunnel can be used to evade provider rate limits.

Mechanism

Install-time daemon startup, login persistence, and optional verified remote tunnel binaries.

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The install hook starts a background daemon on ordinary installs and runs enable for global installs.
Global enable writes an operating-system login entry for the proxy.
The optional WARP feature downloads and runs third-party tunnel binaries, supporting rate-limit bypass.

Evidence against

The lifecycle hook skips npx, source checkouts, CI, and an explicit opt-out setting.
The uninstall hook invokes disable to remove the service.
Downloaded WARP files are checked against published checksums before being written.
No source evidence shows credential harvesting or exfiltration.
