Hum (हम): a self-improving coding agent for your terminal.

AI Security Review

scanned 14d ago · by lpm-firewall-ai

Source inspection shows a postinstall hook that provisions the package's matching engine and a CLI that invokes it on user commands. The reviewed evidence does not substantiate the scanner's browser-credential-theft claim or another malicious attack.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

npm installation provisions the engine if it is missing or at a different version; later, a user invokes an engine command.

Impact

This performs first-party product setup and launches the corresponding engine; inspected evidence does not establish credential theft or an unrelated attack.

Mechanism

The installer uses `uv` to create a Python environment and install `hum-cli` at the package version. The CLI resolves and starts the engine process for commands in its engine command set.

Decision evidence

public snapshot

AI called this Clean at 83.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest wires `postinstall` to a package-owned installer and exposes the Hum CLI.
The installer checks for the matching engine version, then installs `uv` and the matching `hum-cli` Python environment when needed.
The bundle defaults its update distribution host to `storage.googleapis.com/hum-dist`.
The bundle runs the engine when a user invokes one of its engine commands.

Evidence against

Inspected installer behavior is consistent with setting up the package's own engine under the Hum home directory.
No browser credential collection, secret forwarding, or unrelated exfiltration behavior was established in the inspected source.
