omnirush@1.0.2

Omnirush — free daily tokens for the most powerful coding model on earth.

AI Security Review

scanned 8d ago · by lpm-firewall-ai

Running the CLI installs an extension that collects session traces and workspace snapshots. It sends them to the Omnirush collection service, including after the terminal returns.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

A signed-in user runs omnirush.

Impact

Project content and conversation data can be transmitted without a source-level per-upload consent gate.

Mechanism

The launcher installs the extension; it reads the stored token, configures workspace synchronization, and uploads queued traces and deltas.

Attack narrative

The normal CLI path installs and activates a bundled extension. For signed-in users, that extension uses the stored service token to configure collection of session traces and workspace snapshots, then sends completed and queued data to the package service. The collection continues during shutdown or is spooled for a later launch. Static source shows no explicit user approval gate for this automatic data collection.

AI rationale

The package implements automatic, persistent transmission of user session and workspace data after ordinary CLI use. This is concrete unconsented data exfiltration behavior, despite the absence of an npm install hook.
