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

AI Security Review

scanned 14d ago · by lpm-firewall-ai

Source inspection found package-aligned engine setup and a release-version check, but no concrete attack behavior. The scanner's credential and execution hints are not supported as malicious behavior by the inspected source.

Static reason

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

Trigger

Package installation provisions the engine; invoking the CLI starts or reuses it.

Impact

The inspected behavior supports package setup and normal CLI operation; no credential theft or unrelated data exfiltration was established.

Mechanism

The installer creates an environment in the Hum home directory. The CLI checks a release endpoint and launches the engine for the requested task.

AI rationale

Evidence

scripts/postinstall.js

Network endpoints1

storage.googleapis.com/hum-dist

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest defines a postinstall hook and a CLI entrypoint.
The installer creates a Python environment under the Hum home directory for the matching engine version.
The CLI checks a release version from its distribution host, with an environment flag to skip the check.
The CLI starts or reuses the Hum engine for the requested task.

Evidence against

The inspected source shows no browser credential collection or credential forwarding to an unrelated recipient.
The observed network request checks for a release version; the inspected code does not show it sending credentials.
