re: Hacked/Compromised?? Thoughts/Suggestions Needed.

What others said x1000 about not using the same password for all your logins, that's basic security 101. If you don't use a PW manager at least come up with some way of customizing PWs for sites in a way you can remember so they aren't all the same.

Not all websites handle their user info well. It's quite possible that a password on one site was not sufficiently protected such that hackers could get the plain text version and then since it's the same for all your accounts your email, Walmart etc were compromised.

You also need to contact your credit card that was charged and likely cancel and get a new one sent.
