If your credit card information has been stolen and used for fraudulent purchases, here are some steps you should take to protect yourself:

1. Immediately contact your credit card provider and report the unauthorized activity.
2. Request that new credit cards be issued, and note what additional protections the card provider might already have in place, such as security codes.
3. Request a fraud alert to be placed on your credit report, and consider freezing your credit.
4. Monitor your credit card statement regularly for continued and future fraud activities.
5. Consider filing a police report with your local police station.
