Brutforce CV2

[Blue*]

Hello
One of my friends managed to hack into an online DB with over 1.5k cards.
DB only had CCN+EXP it didnt save the CV2.
[Visa and MC not Amex]
I came up with one idea to create a software that works with Authorize.net api that will try to transact CCN+EXP+Random CV2 (from 000 to 999)
like a dictonary attack.

My question is.
Will bank redflag the card after soo many tries of incorrect Cv2?

The method Is not trying random cvv2. You have to choose one CVV2 and you'll end up with 10-15% of valid Information and to your amount which Is small It's not worth it In my opinion
