This vulnerability isn't a huge one and isn't even so much technical but I thought it was at least worth addressing. This problem arises from the Secret Questions seciotion of the pay pal account, and as far as I know this only affects canadian members. One of the secret questions you can select when setting up your pay pal account is to enter the last 4 digits of your drivers license. The problem here, is that the last 4 digits of most any canadian drivers license are the month and day that you were born. For example of the last 7 digits of my drivers license were 8-40726 then I would be born on july 26th, 1984. Canada uses this as a secondary measure to ensure validity of age against people modify their license (I used to work in a bar). So anyone who wanted to know the answer to the last 4 digits of your drivers license secret question would only need to know the day and month you were born to know the answer. Seeing as how the other 3 possible secret choice questions are kinda weak anyways, it doesn't provide much security against someone who has done their homework from stealing your money. Also it is my guess that this question was just left over from the secret question on the american paypal, which american licenses don't use the same method, I think. Anyways, have fun. J.
