I heard about this on the news too. This time I'm in the clear as I don't have an account with eBay. I did get hit with the Target hack, had to get my debit card re-issued - but I caught that quickly as I'm constantly monitoring my credit/debit cards.
It's for reasons like this that I choose not to subscribe to some of those "all inclusive" online financial tools. Yes, it's a nice idea to place all your financial information in one "secure" site, however, if that site has not yet been hacked - you really don't know what security weaknesses are there lurking, waiting for some hacker to exploit. I'm more likely to trust a site after it's been hacked rather than before. Why? Because the hack will expose the weaknesses in the system and the business will plug the holes.
Sites being hacked is just something we all need to deal with in this age of information technology. As technology continues to advance, so to criminal techniques and those trying to stop them. Those common sense rules of thumb are still be best defense - change your passwords often; don't use "easy to guess" passwords, be skeptical when you store any financial information online - any time you do, it's a calculated risk regardless of how secure the site; regularly monitor your financial activity for unusual charges.
Keep in mind - hacking isn't the only way people get your account information. There are those who run programs to find credit card/security code combinations until they find one that works, then use it. More of a brute force type method for stealing, but still happens. That's most likely how one of my credit cards were hacked a couple years back - it was a card I have as a backup and don't use at all, then all of a sudden I got a couple charges. To the card's credit - they contacted me within the hour of those charges being made flagging them as fraudulent. Was impressed.
