Not possible to tell from the screenshot.
What is the URL?
If the blur effect is set on top, but the contact information is already
embedded in the webpage source, then you 1. crawl the page (with HTTrack), and
2. post-process (with separate custom coding) the result to extract whatever
you find in the source.

If the data is not already embedded in the webpage source, then you are
basically out of luck, as then it might be very much issue an AJAX request,
triggered after a human solved the captcha. Such dynamics are not possible to
solve with HTTrack. You should also think about why a captcha was installed in
the first place.
