@viraatdas/rudder@2.14.63

A Claude Code-style terminal app for running coding agents with worktree-isolated runs.

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The package has no demonstrated install-time credential theft or hidden remote payload, but its postinstall mutates global tooling and its runtime updater installs another release of itself. Broad credential-upload functionality is explicit-command gated, so the evidence supports a warning rather than a block.

Static reason

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

Trigger

npm postinstall; then normal CLI startup for auto-update, or an explicit cloud secret/snapshot command.

Impact

It can mutate globally installed software and transmit high-value local credentials when cloud features are invoked.

Mechanism

Automatic external tool installation, self-update, and cloud credential synchronization.

AI rationale

Evidence

scripts/postinstall.mjsdist/version-check.jsdist/cloud.jspackage.json~/.claude/.credentials.json~/.codex/auth.json~/.config/gh~/.aws/credentials~/.npmrc

Network endpoints2

registry.npmjs.orgrudder-cloud-control.fly.dev

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The install hook automatically invokes Homebrew or Cargo to install jj when it is absent.
Normal CLI startup checks the registry and can globally install and rerun a newer release of this same package.
Cloud snapshot code includes agent authentication files, cloud credentials, shell configuration, and package-manager configuration by default.
The cloud secret-sync command reads selected credentials and environment values, then posts them to the package cloud service.

Evidence against

Secret synchronization is reachable only through the explicit `rudder cloud secrets sync` subcommand.
Cloud requests require a configured login token when a token is required.
No obfuscation, hidden evaluator, or install-time credential upload was found.
The postinstall hook does not write AI-agent configuration or contact a network endpoint directly.
