AI Security Review
scanned 7d ago · by lpm-firewall-aiThe postinstall performs first-party agent extension setup, including writing agent configuration and potentially installing a related global MCP package. This warrants a warning; the inspected source does not establish a block-eligible attack.
Static reason
High-risk behavior combination matched malicious policy.; source fingerprint signature matched known malicious package; routed for review
Trigger
Installing the package through npm triggers postinstall.
Impact
Agent clients may load the package’s skills and MCP server without a separate setup command.
Mechanism
The hook runs the shared installer, writes skill files and MCP configuration for detected client targets, and may install or update @wowok/agent-mcp globally.
AI rationale
The postinstall performs first-party agent extension setup, including writing agent configuration and potentially installing a related global MCP package. This warrants a warning; the inspected source does not establish a block-eligible attack.
Evidence
package.jsonscripts/install.jsdist/installer.jsdist/targets.js
Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs scripts/install.js automatically after installation.
- The hook calls runLifecycle, which acts only on postinstall and installs skills into user-scoped targets.
- The default target list covers every configured client target; the installer adds a WoWok MCP entry to client configuration.
- The installer may install the related @wowok/agent-mcp package globally and skips MCP management only when a specific environment flag is set.
Evidence against
- The inspected behavior installs this package’s own skills and its named WoWok MCP server; no credential transfer or unrelated payload execution was identified.
