@viraatdas/rudder@3.5.5

⚠ Under review

A TUI for managing coding agents: run Claude Code, Codex and opencode side by side, each in its own isolated jj workspace.

AI Security Review

scanned 4d ago · by lpm-firewall-ai

The inspected JavaScript behavior appears aligned with Rudder's CLI, but its dashboard launches bundled native executables that the available offline analyses could not inspect. No malicious behavior was established; manual review is needed to resolve the executables' behavior.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

Starting the Rudder dashboard on a platform with a bundled native executable.

Impact

The executable's effects remain unknown, so the package cannot be cleared from static source inspection alone.

Mechanism

The JavaScript resolves and launches the platform-specific executable; offline analysis could not identify its format or behavior.

Decision evidence

public snapshot

AI called this Manual Review at 84.0% confidence as Unknown with high false-positive risk.

AI review observations

dist/main.js launches a bundled native executable for the dashboard, passing through command arguments and the process environment.
Reviewer analyses for the macOS x64, macOS arm64, and Linux x64 binaries report unsupported formats, leaving their behavior unresolved.

Evidence against

The postinstall path sets up Rudder's workspace tool; its release archive is checked against a pinned SHA-256 before installation.
Inspected Codex usage code reads a saved access token and sends it to ChatGPT's usage endpoint.
