You should be fine. It said that your credit card wasn't in their database. Windows prompts aren't allowed to lie.

"Dixie Normous" sounds legit, I thrust that guy, where do I download the app?

No, it says right there your info was not in any hacker database.

I bank with Dixie Normous.

Nah, it's probably fine. Don't bother checking your accounts for the next 4 months, you have no reason

What can they do without the security code?

Benefits of Debit, this would not be able to happen

Isn't there supposed to be a security code? The three-digit thing? Not sure you can brute-force that easily.

Hey, if you want i can run to the town hall and check with the official records as well? Just give me your credit card number, expiration date and security code.

You're still using windows 7 so yeah /s . But jokes aside your fine all credit card numbers are automatically redacted. Put yours below with the CCV code and expiration date, and watch the magic happen.

Look at that lovely, lovely Aero UI. Microsoft reserved a special place in hell for themselves the minute they killed Aero.

No issue if the info gets hashed and the service's database is only searched for the hash à la have I been pwned, it's probably legit 😜
