FUUUUUUUUUUUUU

A stranger with a German sounding name send me over 400 euros through PayPal.

Probably a scam. Can't open a dispute with PayPal because I am on the receiving end.

Be careful with scams. The last scam-looking thing I've seen pop up a lot is a mail from Paypal saying my account has been terminated due to a breaking a rule that encompasses a lot of different things (from scams to illegal activity).

I don't even use Paypal all that much so I knew this had to be a mistake. I just have a CardA that sometimes gives me trouble when paying online because the bank is kind of shit, but doesn't give me trouble when paying with it through Paypal.

Naturally, I'm curious about this. However all the details are in some mystery PDF attached.
At this point I just opened the PDF out of morbid curiosity in another machine. The mystery PDF contained a link to an external site where I could "view what was wrong". Naturally, I just deleted the file.

What tipped me off originally was the domain name. the mail didn't come from paypal.com, but paypal-live.com.
