Ali Express and credit card frauds?

A lot of people around me claims that they have been victims of credit card thefts after shopping on Ali Express (one person even claims it happened several times). I am very sceptical to this because AE have hundreds of millions of customers and if someone at AE was stealing CC-numbers, it should be millions of victims and a big scandal.

Googling for it returns a lot of results such as

https://www.reddit.com/r/Aliexpress/comments/6p5tjo/how_safe_is_credit_card_info_on_ae/

where people claim that their CC details were stolen at AE, but they never substantiate their claims. To me, it sounds like an urban myth and it is much more likely that it happened at a local gas station or taxi or something mundane like that.

Are there any official reports that support/refute that AE has a problem with CC frauds? Or that it ever happened (yes, I know you can’t prove non-existence)?
