CWmike writes: The Federal Bureau of Investigation has opened an investigation into the leak of an estimated 114,000 Apple iPad user e-mail addresses. Hackers belonging to a group called Goatse obtained the e-mail addresses after uncovering a Web application on AT&T's Web site that returned an iPad user's e-mail address when it was sent specially written queries. After writing an automated script to repeatedly query the site, they downloaded the addresses, and then handed them over to Gawker.com. Now the FBI is trying to figure out whether this was a crime. U.S. law prohibits the unauthorized accessing of computers, but it is unclear whether the script that the Goatse group used violated the law, said Jennifer Granick, civil liberties director with the Electronic Frontier Foundation. 'The question is, when you do an automated test like this, [are you] getting any type of unauthorized access or not,' she said. If it turns out the data in question was not misused, it is unlikely that federal prosecutors will press charges, she added.
