 All right, so your credit card number is on the dark web. What should you do? Number one, contact a credit reporting agency like Equifax, TransUnion, Experian, and you want to request a credit freeze. This will stop anyone else from accessing your credit. It makes it harder for thieves to open new accounts. And then you also want to ask for these free fraud alerts from the credit reporting agencies. And then finally, make sure that you shut that credit card down and you get a new one, especially if your bank was part of the leak.
