Removed suggestion- already done. Sounds more like the PayPal account was hacked, not your bank account. Sounds like this is already covered, but if your PP account is linked to any other active payment forms (other credit cards/etc.), then I would suggest contacting them and getting new account numbers as anyone who successfully logged onto your account could view the current payment account details.
That is the risk of allowing others to hold details on your accounts. If the first account is hacked, then your other payment accounts are vulnerable.
