PayPal (EBAY) is on guard against hackers looking to crash its site after it cut ties with WikiLeaks. On Wednesday, hackers hit Visa (V) and MasterCard (MA), then unsuccessfully tried to bring Amazon (AMZN) down on Thursday. After they reportedly threatened PayPal, the company said it will more closely screen new developers.
