AI Security Review

scanned 3h ago · by lpm-firewall-ai

Browser runtime code fetches a remote Google Tag Manager response and evaluates it as JavaScript. Separate runtime code injects a remote IP-information script and fetches site content/API data.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Loading `js/custom/all.js` or `js/custom/ip_check.js` in a browser page.

Impact

A compromised or changed remote endpoint can execute arbitrary code in visitors' page origin.

Mechanism

Remote script retrieval followed by dynamic JavaScript execution.

Rationale

The package contains a concrete browser-side remote code execution mechanism, but the endpoint is a declared Google Analytics resource and source inspection found no install hook, local harvesting, or destructive behavior. Warn rather than block.

Evidence

package.jsonjs/custom/all.jsjs/custom/ip_check.jsjs/sw.js

AI called this Suspicious at 90.0% confidence as Critical Vulnerability with medium false-positive risk.

Evidence for warning

`js/custom/all.js` fetches Google Tag Manager code and executes it with `new Function(n)`.
This remote-code path runs during browser script load, without user interaction.
The same bundle fetches package-site APIs and inserts fetched `/notice` HTML into the DOM.
`js/custom/ip_check.js` injects and executes a remote script from `lanyundev.com/api/ip_info`.

Evidence against

`package.json` has no preinstall, install, postinstall, or prepare lifecycle hook.
No package JavaScript references `child_process` or Node credential/file APIs.
No evidence of npm-install-time mutation, persistence, or local credential harvesting.
Other `Function` hits are bundled framework/polyfill code; no `eval(` or `atob(` occurs in `js/custom/all.js`.
