AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The automatic Git-hook mutation and detached server launch create a concrete install-hook risk. Source inspection did not establish the stronger malicious behaviors required for a publish block.

Static reason

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

Trigger

npm installation runs postinstall.

Impact

The consumer project's pre-commit behavior changes and a background process binds locally.

Mechanism

Lifecycle hook writes a Git hook and spawns a detached local server.

AI rationale

The automatic Git-hook mutation and detached server launch create a concrete install-hook risk. Source inspection did not establish the stronger malicious behaviors required for a publish block.

Evidence

package.jsonscripts/postinstall.js.git/hooks/pre-commitdist/index.js

Network endpoints1

127.0.0.1

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

The manifest automatically runs a postinstall script.
Postinstall overwrites the consumer checkout's pre-commit hook.
Postinstall starts a detached web-server process unless CI or an opt-out variable is set.

Evidence against

No self-dependency is declared in the manifest.
The reviewed lifecycle code contains no credential collection or outbound network request.
The web server defaults to a loopback host.
