Install Maxy — AI for Productive People

AI Security Review

scanned 3mo ago · by lpm-firewall-ai

Source confirms a dangerous explicit-user-command agent configuration mutation, but no automatic lifecycle execution, payload execution chain, or exfiltration was established. Policy classifies this as warn-level capability abuse rather than malicious blocking behavior.

Static reason

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

Trigger

User runs create-maxy-code.

Impact

The installed Claude environment can operate without normal permission prompts and the CLI can persist services and modify host dependencies.

Mechanism

User-invoked Claude permission bypass, plugin registration, and host provisioning.

Decision evidence

public snapshot

AI called this Suspicious at 94.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

dist/index.js explicitly installs and configures Claude Code when its bin is run.
dist/permissions-seed.js writes Claude settings with defaultMode "bypassPermissions".
dist/index.js installs Claude plugins at user scope and creates persistent services.
The CLI performs privileged system/package installation and persistent deployment.

Evidence against

package.json has no preinstall, install, or postinstall hook; prepublishOnly is publisher-side.
All observed actions are reached from the explicit create-maxy-code CLI entrypoint.
Network URLs support declared dependency/service installation; no remote payload is fetched and executed by package code.
No credential harvesting or exfiltration path was confirmed in inspected installer sources.
