Is World Time safe?

Low risk

World Time loads HTML and links from linangdata.com into its popup and opens server-supplied links in new tabs.

When the popup opens, the extension requests three pages from linangdata.com and inserts the returned markup directly into the popup as links and banners. Links marked as tab-openers open in a new browser tab at whatever address the server provides. The requests carry a source label and a timestamp-based identifier.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

What actually happens
You did this

You click the World Time toolbar icon to open the popup.

The extension did this

The popup requests three pages from linangdata.com and writes whatever HTML comes back into the popup.

Links in that HTML open in new tabs at the address the server supplies.

The code that does this

Fetch, inject and tab-open handler in js/app.js

Readable version

The source ships unminified, so the shipped and readable forms are the same code. No JSON parsing, sanitizer or URL allowlist sits between the response and the DOM or the tab call.

js/app.js
// response body (string) -> $(...).html(body)// any element.navopentab -> chrome.tabs.create({ url: element.href })
What the popup sends and accepts
  • Request source tag
    source=worldClock

    Identifies which extension is asking for content.

  • Request timestamp
    uuid=1759312845123

    Millisecond clock value sent as a cache-busting uuid.

  • Response body
    <a class="navopentab" href="https://example.com/offer">Offer</a>

    Markup the server returns and the popup inserts as HTML.

  • Link target
    https://example.com/offer

    The href of a navopentab link, opened in a new tab on click.

Hosts contacted when the popup opens
    • linangdata.com

    Serves dynamiclinks.php, bannertop.php and bannerbottom.php whose output is inserted into the popup.

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 World Time 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.
