Monitor all of your accounts for any suspicious activity on a regular basis. If you see something unfamiliar, it could be a sign that you’ve been compromised. Keeping receipts and tracking your account activity will help you to see a charge that is out of the ordinary, and will help you assist the company in tracking that suspicious activity; plan to partner with that company in the investigation by providing them as much information as possible. Quick reactions can save time, money, and effort for everyone involved.
