Let's look at the really scary one.
App name's stripped off.
This app tells you the personal unique ID,
which is whited out because this is from Lee's personal phone,
the card bin, so the last three or four digits
on the back of your card.
Here, display name, 9563.
That is the credit card information.
So what it's showing you, the expiration-- and I love this.
It gives you the expiration in Unix Epoch, but then
it also converts it for you--
the billing zip code, the name of it.
So now, we know it's a MasterCard that ends in 9563.
That's the user's billing zip code.
This is when it expires.
This is the card number on the back,
and this is that user's ID.
You need 8 digits in between, and you have full-on credit
card theft potential here.
It's not good.
Some of the apps do a really good job.
Some of them do a hideous job.
Do not expect-- once you're like,
OK, my banking app is actually pretty good, always check it.
What I do is I consistently load my apps
and then minimize them to see if it even gives a blank screen.
If it's not giving you that blank screen,
what else is going on in the background?
