Flurin:
I´ve followed the link: it requires more or less the same information you need to provide when you open a new Paypal account, but regarding credit card information:
-it requires not only the Verification Number (as Paypal does) but also your Card PIN Number!!!
-it also requires your Bank Name, Bank Telephone Number, Routing Number (something that appears on your checks) and Bank Account Number !!!!!!!!
This is phishing, definitely.
Not sure if there´s a way to report Paypal what´s going on with this.
As for my bank, they have inserted a big message on the main page of their website, stating that THEY DON´T REQUIRE CONFIDENTIAL INFORMATION VIA E-MAIL.
When Paypal gets aware of this affair, they should do something similar.
FUCK PHISHING!!!!!
