Hacking Paypal

Kali ini saya mendapat informasi mengenai hacking paypal yang sangat menarik. Saya kutip dari http://etutorials.org

Pay someone quickly without going to the trouble of setting up an account.
If you don't have a PayPal account and you want to see what the fuss is about, send someone money using PayPal. After all, everyone owes someone for something. Perhaps you owe a coworker for lunch, a friend who bought you a ticket to the big game, or another friend who sold you his old DVD player. Why not pay them via PayPal?
But to send someone money, you'll have to sign up for an account. Or will you? The answer is no, as long as the recipient has a PayPal account!
Using this procedure, you can also request and accept payments without requiring the customer to sign up for a PayPal account. Just fill in your own email address into the URL discussed here and send it to your customers.

To send money without creating a PayPal account, open up any web browser, and type this address (URL):
http://paypal.com/xclick/business=
Add the email address of the recipient of the money to the end of the URL, like this:
paypal.com/xclick/business=reg@paypalhacks.com
After pressing the Enter key (or Return on the Mac), the email address (reg@paypalhacks.com, in this case) will be sent to the PayPal web site, which will look up the user's account. If the email address refers to an existing PayPal account, you will see the Payment Details page (shown in Figure 2-7) with the following information:

Pay To
The email address of the recipient of your payment.

Payment For
An optional field, into which you can enter a note describing what the payment is for.

Currency
The currency it expects you to use; the default is U.S. dollars.

Amount
In this example, you will be required to enter the amount you wish to pay, since you didn't put the amount in the URL.
