The story, "UK charges two, arrests two more linked with Anonymous," which posted to the newswire Friday, has been clarified in the first sentence of the fourth paragraph to refer to HBGary Federal. The fourth paragraph now reads:

She was allegedly instrumental in the hacking attack in February against HBGary Federal, a security company, which sought to expose Anonymous. In retaliation, Anonymous hacked the company's website and released more than 50,000 e-mails, exposing questionable business deals and causing HBGary Federal CEO Aaron Barr to resign.
