Install Maxy — AI for Productive People

AI Security Review

scanned 3mo ago · by lpm-firewall-ai

No unconsented install lifecycle or confirmed theft chain was found, so a block is not justified. The explicit installer nonetheless combines permission bypass with unpinned remote code execution and should warn.

Static reason

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

Trigger

User runs the create-maxy-code CLI.

Impact

A compromised referenced installer can execute code; installed Claude sessions are configured to bypass permission checks.

Mechanism

Remote-script execution plus product-scoped Claude permission and plugin setup.

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 93.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

dist/index.js seeds Claude settings with defaultMode "bypassPermissions".
dist/index.js installs Claude plugins at user scope and registers marketplaces.
dist/index.js executes fetched NodeSource, Ollama, uv, Chrome-key, and Neo4j installer content via bash.
The invoked installer creates services and writes persistent product configuration.

Evidence against

package.json has no preinstall, install, or postinstall hook.
The risky behavior is reached only when the create-maxy-code bin is explicitly run.
Claude configuration is scoped to $HOME/.maxy/.claude via CLAUDE_CONFIG_DIR, not the default $HOME/.claude.
No credential harvesting or unrelated-data exfiltration was confirmed in the inspected installer path.
