AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The install hook performs non-consensual consumer-project and existing agent-config mutation. Its scope appears limited to this product and no exfiltration or self-dependency chain was found, so a warning is more proportionate than a block.

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

npm install or pnpm add when the native prebuild is available.

Impact

The package changes project files and user AI-agent configuration without an explicit setup command.

Mechanism

Postinstall bootstrap and MCP configuration rewrite.

AI rationale

Evidence

package.jsonbin/lib/postinstall-prebuilds.mjsbin/lib/postinstall-host-bootstrap.mjsbin/lib/install-upgrade.mjs.envdataREADME.mdINSTALL.mdLicence.mdghostcrab-skills.cursor/mcp.json.cursor/mcp.json.bak.codex/config.toml.codex/config.toml.bak

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest runs a postinstall script automatically.
Postinstall creates consumer .env and data paths and adds package-controlled documentation and skill symlinks.
Postinstall invokes an upgrade routine without dry-run or process-kill opt-out.
That routine rewrites existing Cursor and Codex MCP configuration to register this package's server.

Evidence against

The configuration entries are specifically named for GhostCrab rather than arbitrary servers.
No runtime dependency on this package's own name was found.
No credential harvesting or external-network action was found in the install path.
