AI Security Review
scanned 11d ago · by lpm-firewall-aiSource confirms a guarded first-party agent setup capability in an npm postinstall hook, which warrants a warning under the agent integration policy. The inspected behavior does not establish a malicious attack or support a publish block.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
npm runs the registered postinstall hook in an eligible node_modules context.
Impact
Project-level Claude guidance and settings may be added during installation.
Mechanism
The hook prompts and then copies CLAUDE.md and .claude/ files into the detected project root if they do not already exist; a blank answer continues with the copy.
AI rationale
Source confirms a guarded first-party agent setup capability in an npm postinstall hook, which warrants a warning under the agent integration policy. The inspected behavior does not establish a malicious attack or support a publish block.
Evidence
package.jsonbin/postinstall.jsCLAUDE.md.claude/
Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json registers a postinstall hook that runs bin/postinstall.js.
- The hook runs only in a node_modules install context, after project-root and template checks.
- The hook prompts before copying AI assistance files; declining skips the copy, but a blank response proceeds.
- The hook can add CLAUDE.md and .claude/ files to the consuming project when those destinations do not exist.
- The CLI also offers setup-ai with a confirmation prompt and skips copying when declined.
- The inspected view template contains ordinary view lifecycle examples and no active network behavior.
Evidence against
- The lifecycle setup is limited to package-provided Domma assistance files and checks for existing destinations.
- The inspected sources show no credential collection, exfiltration, or remote payload execution.
