WikiLeaks hacktivists downloading free 'spam attack' software

Wikileaks supporters are downloading increasing amounts of the spam-shooting software used to attack companies seen as hostile - a development that could challenge even internet giants such as PayPal and Amazon.com during the crucial Christmas shopping season.
US data security company Imperva says downloads of the attack program used to bombard websites with bogus requests for data have jumped to over 40,000, with thousands of new downloads reported overnight.
