Cloudflare unveiled Precursor, a new tool designed to detect bots based on how they interact with web pages. This system injects JavaScript into HTML responses to track user behavior like pointer movements and keyboard activity. With over 1 trillion requests analyzed daily, Cloudflare aims to catch bots by looking at the big picture of user sessions rather than individual actions. Precursor collects data continuously throughout a session and sends it back for analysis, helping developers identify suspicious patterns that might slip past traditional bot detection methods.
