Paypal is a lovely target, so it is right up there in terms of numbers of attackers, and skilled mechanisms to get money out of it, which is why they are getting much better at responding...I know, a long way to go, but they are now aiming the right way.
Most successful attacks there seem to use old fashioned routes - main one being reusing a password shared across sites, often somewhere with weaker security. Don't do it folks!!
Also current trojans are pretty smart - realistically now, if you visit malicious sites your av is not going to save you any more. And more real sites are becoming malicious through their own accidental vulnerabilities.
Apple is being targeted more and more, so don't rely on OSX being safe...attackers can get in just as fast as a windows box.
Use layers, trust as few sites/individuals as possible, and watch your accounts for oddities.
Be safe kids
