When there is text in the form of images, there is OCR. In the same way, with the verification code, some people are studying how to break the verification code.
There are two ways to crack the verification code: simple image recognition, and complex manual coding (it is said that a group of Filipinos were hired). Manual coding is basically 1 minute per piece, which is quite cheap.

Of course, I haven’t watched the detailed video. It would be easier if there were design loopholes that would allow the verification code to be bypassed (generally unlikely)
