Bypassing Captcha when Chrome opened in remote debugging mode

[ds4573]

I've used SeleniumBase OK in two situations independently - it's great.

1. Log onto a website and bypass Cloudflare
2. Connect to an existing Chrome Window already opened via remote debugging (--remote-debugging-port=9222 etc etc)

Has already managed to combine the two? eg

1. Open Chrome with remote debugging
2. Use SeleniumBase to connect to open Chrome
   ---- so far so good
   3.When I then try to log on to the required website, Cloudflare stops things. I assue that it detects Chrome in remote debugging mode and there's no way around this.

Any ideas / suggestions? The application might seem weird, but I have a system using SeleniumVBA in Excel that no longer works because CloudFlare blocks login. I can rewrite everything to use SeleniumBase but am trying to avoid the work. If I can get logged in via SeleniumBase to the open Chrome window, I can then connect into this with SeleniumVBA and its business as usual.

Look forward ot any suggestion, Dain

Taking control of existing browsers via remote-debugging-port is covered in https://www.youtube.com/watch?v=vt2zsdiNh3U.

Note that if you take control of an existing browser that wasn't stealthy to begin with, then you probably still won't be stealthy.

Plenty of examples of Cloudflare-bypass in the SeleniumBase/examples/cdp_mode folder:

• https://github.com/seleniumbase/SeleniumBase/blob/master/examples/cdp_mode/raw_gitlab.py
• https://github.com/seleniumbase/SeleniumBase/blob/master/examples/cdp_mode/raw_planetmc.py

Thanks MIke, appreaciate the quick response.
Launching Chrome in remote debugger mode via command prompt is not stealthy.
So is there actually a way to do it to make it stealthy? Can SeleniumBase be used to do this?

All these examples are bypassing Cloudflare:

• https://github.com/seleniumbase/SeleniumBase/blob/master/examples/cdp_mode/raw_gitlab.py
• https://github.com/seleniumbase/SeleniumBase/blob/master/examples/cdp_mode/raw_planetmc.py
• https://github.com/seleniumbase/SeleniumBase/blob/master/examples/cdp_mode/raw_ahrefs.py
• https://github.com/seleniumbase/SeleniumBase/blob/master/examples/cdp_mode/raw_cf.py

(And the remote-debugging-port is used to to connect the CDP-Driver to the browser that was spun up with the stealthy version of Selenium. That's why you can call sb.reconnect() from those examples and call regular Selenium WebDriver methods again.)

Sorry Mike, you're dealing with a Python-challenged 72 year old Australian. I'm OK with Excel VBA, you are operating at about 10 levels higher in the programming world.

But guess what, I got it to f***ing work. Turned out to be easy.

I ran the gitlab example with the URL changed to the page I want to work with, got the page open with Captcha bypassed, and left the page open by using a checkpoint() at the end of the code. Then I ran my Excel VBA code using port 9222 (guessed the number) and it hooked in no problem.

One question, the Chrome window closes when the code is complete. Is there any way of leaving it open (other than checkpoint() or similar?

If you're ever around the Sunshine Coast, Queensland, Australia, I'll buy you a beer.

breakpoint() is the way to keep the browser open at the end of the script.
