Hacked!!

I just so happen to check one of credit card accounts to see how many rewards points I have earned because I was thinking about doing a little shopping. While I was perusing my account, I noticed a charge for $226.68 to a Paypal account. This was very strange because the only thing that I had charged to this particular credit card account this month was a few pizzas from Papa Johns on 4/29. I know I wasn't shopping on eBay and that is the only place I use Paypal account so I called my bank to find out more about the purchase. No luck, I called too late and I will have to deal with it in the morning. I decided to do a little snooping so I checked out my Paypal account. I could see the details of the transaction clearly. Somehow an unknown person with an email account "jailbrek" had lifted $220 plus $6.68 fee from my credit card and this transaction had the subject "You've got money!" so I guess they decided to take it!!!! I filed an unauthorized transaction report at Paypal and I am awaiting the results of the investigation (10 days) to see if they will refund my money. I changed all my passwords and deleted my credit card for this account. It really makes you wonder how secure online banking/shopping really is.
