binance nft limit

I saw someone get hacked buying nft for 400k busd etc 60k -90k and so, but when i enter in app i see binance nft daily limit its 1000 busd , and i can't increase it "user center" , and so on if you can, it is istant? I see it requires 2fa for increase limit , how hackers can buy 400k nft , enter in valid session , increase daily limit do all this shits without users recognize this?

​

I see it quite impossible , there is a proof of what happening ? Or are trolls , competition naabs exchange that try to make bad pubblicity to binance?
