Google reCAPTCHA v3 works silently, scoring requests from 0.0 to 1.0 without user interaction. It analyzes behavior. A low score triggers additional challenges or outright blocks. Attackers cannot easily replay or solve a score.
Tools like Selenium or Puppeteer, combined with mouse movement randomization and cookie/session reuse, can sometimes fool Google’s risk analysis engine. Adding a solving service makes the success rate climb to ~70%.
: For a few dollars per thousand solves, malicious actors can hire human labor in "CAPTCHA farms" to bypass these gates manually, rendering simple puzzles nearly useless against motivated attackers.
