Plenty of improvements to mouse movement algorithms have already been made and they’re still evolving. While the blog post and the product it introduces offer some interesting ideas, they don’t yet reach the robustness of modern anti-bot solutions and still trail current industry standards. I doubt it would take me - or any average reverse engineer - more than five seconds to bypass something like this. There are already numerous open source mouse movement libraries available; and even if they didn’t exist, writing one wouldn’t be difficult. Yes, mouse movement or keyboard data can be quite powerful in a modern anti-bot stack and an in depth analysis of it is genuinely valuable, but on its own it’s still insufficient. Relying on this data alone isn’t costly for the attacker and offers little real protection.
