The first thing to do after you're involved in a hack, according to experts
There's an order of operations when you've been involved in a hack like Equifax, Capital One, Wawa, or any of the hacks that have happened in the past few years.
 
1) If you use the service, change your password immediately. Do not reuse an old password.
2) If your data was breached, the experts suggest careful monitoring of bank and credit card accounts 
3) Consider a credit freeze (“for at least a year!”) if your Social Security number was compromised
4) You should expect social engineering scams that will use your information against you. Understand common email phishing scams
 
Be safe out there!
