Late last year, activists attacked websites belonging to companies that refused to do business with WikiLeaks, an online group that has disclosed classified U.S. government documents.
When the activists, who called themselves Anonymous, found out it was being investigated by the Internet security company HBGary Federal, it hacked the company's servers and stole thousands of private e-mails. And then it dumped them onto the Internet.
It was an embarrassment for the security company to get hacked — but the content of some of those e-mails is raising concerns.
First, in conjunction with Apple, News Corp. founder Rupert Murdoch launched a news app called The Daily that publishes exclusively on the iPad.
"New times demand new journalism," Murdoch said to reporters at Manhattan's Guggenheim Museum. "Our challenge was to take the best of traditional journalism — competitive shoe-leather reporting, good editing, a skeptical eye and combine it with the best of contemporary technology."
