What happen to my personal information after i got scammed?

So, i got Au Pair scam.
First, he asked me to give my personal data like full name, address, mobile phone, passport photo page and some money to the travel agent. i sent him the data and the money. and he asked for more. suddenly i noticed that it's scam. so i try to stop keep in touch with him. The problem is, he got my Passport number and my personal information.

I'm afraid he will use it for something bad. will the fake-family will use the victim personal information to do something bad?

Note:
i haven't given them any account number. the crucial things are scanned passport photo page, scanned passport photo, scanned signature.. sooo stupid
what should i do? i read that we can change our passport number. will it work?

welcome to Scamwarners.
I wouldn't worry too much. He asked for your personal information as that is what a real employer would do. He's only after your money, and probably has little interest in doing anything with the info you gave him.
He'll probably have this information for hundreds of people anyway. So the odds of him using yours would be low

weeeeeeeeeeeeewwww........

Thanks God.. It was so freaking me out

Thanks for you answer
