Analysis of Bot Protection systems with available countermeasures 🚿. How to defeat anti-bot system 👻 and get around browser fingerprinting scripts 🕵️♂️ when scraping the web?
Whether you're just starting to build a web scraper from scratch and wondering what you're doing wrong because your solution isn't working, or you've already been working with crawlers for a while and are stuck on a page that gives you an error saying you're a bot, you can't go any further, keep reading.
Anti-bot solutions have evolved in recent years. More and more websites are introducing security measures: from simple ones, such as filtering IP addresses according to their geolocation, to advanced ones based on in-depth analysis of browser parameters and behavioral analysis. All this makes web scraping content more difficult and costly than a few years ago. Nevertheless, it is still possible. Here I highlight a few tips that you may find helpful.
Below you can find list of curated services that I used to get around different anti-bot protections. Depending on your use-case you may need one of the following:
Once you have decided on what type of evasion is going to be needed in your project, you can use the list below to pick the best provider for your project:
This is a non-exhaustive list of companies that provide the most advanced anti-bot solutions for businesses ranging from smaller e-commerce sites to Fortune 500 companies:
Join extra.community. There runs an automated tester Botty McBotface that uses several complicated techniques to determine what exact protection a tested website uses (credits to berstend and others from #insiders).
Important You use this software at your own risk. Some of them contain malwares just fyi. Use with caution.
Legend: 🤮 - Evasion based on noise. ❌ - No. ✔️ - Acceptable (with support libraries or not). 👍 - Very nice.
A ⭐ on this repo will be appreciated!
Here I study various aspects of evasion techniques used to get around bot detection systems used by major online websites. I cover both technical and non-technical matters, including recommendations, references to scientific papers and more.
The technical findings that I am sharing below are based on observations of running web scraping scripts for a few months against websites protected by the major anti-bot solution vendors.
I constantly add stuff to this section. Over time I will try to make it look&feel more structured.
