Is 加搜GEO safe?

Medium risk

加搜GEO downloads JavaScript handlers from files.jiayisiyu.com and injects them into AI chat pages without integrity checks.

The extension polls a version and config file on files.jiayisiyu.com, then fetches the handler scripts named there. It injects them into the page context of AI chat and search sites such as ChatGPT, Claude, Gemini and Google. The executed code is hosted off-package, so the reviewed bundle does not contain the logic that actually runs.

AI-chat helper injects remote JavaScript from files.jiayisiyu.com into AI sites

Code analysis shows the extension downloads handler scripts from files.jiayisiyu.com and injects them into AI-chat pages with no integrity check, so the code that runs is not in the reviewed package.

Remote resources the extension loads
  • Version file
    https://files.jiayisiyu.com/ai-screenshot/config/version.json

    Polled to learn when new remote code is available.

  • Config file
    https://files.jiayisiyu.com/ai-screenshot/config/config.json

    Names the handler file for each supported site.

  • Handler scripts
    https://files.jiayisiyu.com/ai-screenshot/config/handlers/chatgpt.js

    Per-site JavaScript injected into the page.

Host serving the executed code
    • files.jiayisiyu.com

    Serves config and handler JavaScript injected into AI-chat pages; not part of the reviewed package.

Observation

Static analysis finding. This behaviour was identified by reading the shipped extension code and has not yet been reproduced in a live run. The trigger conditions and the exact data sent are read from the code, not from an observed capture.

Where it sends data

Destinations our analysis observed 加搜geo contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • files.jiayisiyu.com

    加搜geo sends data to files.jiayisiyu.com. One other extension we have analysed sends data here.
