We have already covered what is a bot and how it works. Now it was time to dig the topic deeper.
On the second day of OxyCon, Dmitry Babitsky, the co-founder & chief scientist at ForNova, went through a few different methods that websites utilize to recognize suspicious behavior, detect bots, and ultimately block them. If you want to dig deeper into what is a bot, then we have covered it in another article.
Below you’ll find what Mr. D. Babitsky listed as the most popular methods recognizing suspicious behaviour online:
Large amounts of unusual requests and URL’s.
Missing cookies – if you don’t have cookies, it is suspicious. However, if you do have cookies – they can track you.
Miscorrelation between different request attributes – such as the IP address location. Make sure you compare your language and time zone with your IP address’.
WebRTC leaking your real IP address.
Browser performance analysis and comparison with similar configurations.
Once you are marked as suspicious, how does the website track you? There are a few ways you can be recognized by:
Your IP address (if you leak it with WebRTC).
Your user agent.
Request, cipher suite (SSH handshake), browser fingerprint (most browsers show your fingerprint).
Our other OxyCon speaker Allan O’Neil has covered the fingerprinting topic on day one of OxyCon, so keep a lookout for an article on fingerprinting on our blog.
When and if you get blocked, a website will give you some punishment. This can be done by:
Showing you a 404 page.
Giving you captchas.
Giving you fake data.
Thanks to Mr. D. Babitsky for detailing how websites block bots. OxyCon had so many intelligent presentations that we learned so much from, so make sure to check out our blog for more summaries and articles on most OxyCon presentations.
Having a slight FOMO (fear of missing out)? Don’t worry – OxyCon will be held next year as well, so keep a look out for early bird registrations!
