You’ve found the website you need to scrape, set up your scraper and fired it, just to sadly realize PerimeterX has blocked you.

PerimeterX’s dynamically complex bot detection system relies on server-side and client-side checks to distinguish humans from bots. It deploys several layers of protection and, for the most part, manages to do its job without interrupting the user experience.

But don’t fall into despair! There are a couple of things you can try to bypass PerimeterX (called HUMAN now) before giving up on your goal of scraping that delicious data.

Headless Chrome detection and anti-detection

In the post we summarize how to detect the headless Chrome browser and how to bypass the detection. The headless browser testing should be a very important part of todays web 2.0. If we look at some of the site’s JS, we find them to checking on many fields of a browser. They are similar to those collected by fingerprintjs2.

So in this post we consider most of them and show both how to detect the headless browser by those attributes and how to bypass that detection by spoofing them.

See the test results of disguising the browser automation for both Selenium and Puppeteer extra.

Captcha solving with Java and why you should avoid it

In this blog post we are going to show how you can solve [Re]captcha with Java and some third party APIs, and why you should probably avoid them in the first place.
