Tag: anti-scrape
Recently we encountered a website that worked as usual, yet when composing and running scraping script/agent it has put up blocking measures.
In this post we’ll take a look at how the scraping process went and the measures we performed to overcome that.
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.
Given: a webpage to scrape.
If you inspect the DOM tree of that page you will find that quite a few tags are having the keyword dist. As an example:
<link rel="shortcut icon" type="image/x-icon" href="/wcsstore/ColesResponsiveStorefrontAssetStore/dist/30e70cfc76bf73d384beffa80ba6cbee/img/favicon.ico"><link rel="stylesheet" href="/wcsstore/ColesResponsiveStorefrontAssetStore/dist/30e70cfc76bf73d384beffa80ba6cbee/css/google/fonts-Source-Sans-Pro.css" type="text/css" media="screen">

Scraping JavaScript protected content
Here we come to one new milestone: the JavaScript-driven or JS-rendered websites scrape.
Recently a friend of mine got stumped as he was trying to get content of a website using PHP simplehtmldom library. He was failing to do it and finally found out the site was being saturated with JavaScript code. The anti-scrape JavaScript insertions do a tricky check to see if the page is requested and processed by a real browser and only if that is true, will it render the rest of page’s HTML code.
Cyber-attacks are becoming a real threat to businesses both small and large. The damage they bring into people’s lives is more severe than people presume. In 2019, hundreds of billions of dollars went down this tunnel, and the crime is yet to stop. With the evolvement of threat landscapes, attacks are becoming more and more sophisticated. It has also become clear that big companies need to understand that they cannot be 100% secure from such breaches. The real question is, if hackers manage to attack the big companies, how long would it take them to steal your data? The only way to handle this menace is if you understand these basic security strategies and implement them.
